# Config maturity tags #
########################

# As per features adoption and deprecation proposal we support 4 levels of configuration keys maturity:
# * Sandbox -> Experimental/alpha features, not recommended for production use, can be removed at any time without further notice.
# * Incubating -> Beta features, long-term support is not guaranteed.
# * Stable -> General Availability (GA) features for which long-term support is expected.
# * Deprecated -> Deprecated keys, soon to be removed.
#
# For more info, please take a look at the proposal: https://github.com/falcosecurity/falco/blob/master/proposals/20231220-features-adoption-and-deprecation.md.


################################
# Falco command-line arguments #
################################

# To explore the latest command-line arguments supported by Falco for additional
# configuration, you can run `falco --help` in your terminal. You can also pass
# configuration options from this config file as command-line arguments by using
# the `-o` flag followed by the option name and value. In the following example,
# three config options (`json_output`, `log_level`, and
# `engine.kind`) are passed as command-line
# arguments with their corresponding values: falco -o "json_output=true"
# -o "log_level=debug" -o "engine.kind=kmod" 
# Please note that command-line arguments take precedence over the options
# specified in this config file.


###############################
# Falco environment variables #
###############################

# Customize Falco settings using environment variables:
#
# - HOST_ROOT: Specifies the prefix to the underlying host `/proc` filesystem
#   when deploying Falco over a container with read-only host mounts instead of
#   directly on the host. Defaults to "/host". 
#
# - FALCO_HOSTNAME: Customize the hostname output field logged by Falco by
#   setting the "FALCO_HOSTNAME" environment variable.
#
# - FALCO_CGROUP_MEM_PATH: Specifies the file path holding the container
#   memory usage metric for the `metrics` feature. Defaults to
#   "/sys/fs/cgroup/memory/memory.usage_in_bytes" (Kubernetes).
#
# - SKIP_DRIVER_LOADER is used by the Falco fat image to skip the driver loading part.
#
# - FALCO_FRONTEND is useful when set to noninteractive to skip the dialog choice during 
# the installation of Falco deb/rpm packages. This setting is somewhat similar to DEBIAN_FRONTEND.
#
# - FALCO_DRIVER_CHOICE is useful when set to kmod, ebpf, or modern_ebpf (matching the names 
# used in engine.kind in the Falco config) during the installation of Falco deb/rpm packages. 
# It skips the dialog choice but retains the driver configuration.
#
# - FALCOCTL_ENABLED is useful when set to 'no' during the installation of Falco deb/rpm packages, 
# disabling the automatic artifacts followed by falcoctl.


###############################
# Falco config files settings #
###############################

# [Stable] `config_files`
#
# Falco will load additional configs files specified here.
# Their loading is assumed to be made *after* main config file has been processed,
# exactly in the order they are specified.
# Therefore, loaded config files *can* override values from main config file.
# Also, nested include is not allowed, ie: included config files won't be able to include other config files.
#
# Like for 'rules_files', specifying a folder will load all the configs files present in it in a lexicographical order.
config_files:
  - /etc/falco/config.d

# [Stable] `watch_config_files`
#
# Falco monitors configuration and rules files for changes and automatically
# reloads itself to apply the updated configuration when any modifications are
# detected. This feature is particularly useful when you want to make real-time
# changes to the configuration or rules of Falco without interrupting its
# operation or losing its state. For more information about Falco's state
# engine, please refer to the `base_syscalls` section.
watch_config_files: true

#####################
# Falco rules files #
#####################

# [Stable] `rules_files`

# NOTICE: Before Falco 0.38, this config key was `rules_file` (singular form), which is now deprecated in favor of `rules_files` (plural form).
#
# Falco rules can be specified using files or directories, which are loaded at
# startup.
#
# If the entry is a file, it will be read directly. If the entry is a directory,
# all files within that directory will be read in alphabetical order.
#
# The falco_rules.yaml file ships with the Falco package and is overridden with
# every new software version. falco_rules.local.yaml is only created if it
# doesn't already exist.
#
# To customize the set of rules, you can add your modifications to any file.
# It's important to note that the files or directories are read in the order
# specified here. In addition, rules are loaded by Falco in the order they
# appear within each rule file.
#
# If you have any customizations intended to override a previous configuration,
# make sure they appear in later files to take precedence. On the other hand, if
# the conditions of rules with the same event type(s) have the potential to
# overshadow each other, ensure that the more important rule appears first. This
# is because rules are evaluated on a "first match wins" basis, where the first
# rule that matches the conditions will be applied, and subsequent rules will
# not be evaluated for the same event type.
#
# By arranging the order of files and rules thoughtfully, you can ensure that
# desired customizations and rule behaviors are prioritized and applied as
# intended.
# 
# With Falco 0.36 and beyond, it's now possible to apply multiple rules that match 
# the same event type, eliminating concerns about rule prioritization based on the 
# "first match wins" principle. However, enabling the `all` matching option may result
# in a performance penalty. We recommend carefully testing this alternative setting  
# before deploying it in production. Read more under the `rule_matching` configuration.
rules_files:
  - /etc/falco/falco_rules.yaml
  - /etc/falco/falco_rules.local.yaml
  - /etc/falco/rules.d

# [Incubating] `rules`
#
# --- [Description]
#
# Falco rules can be enabled or disabled by name (with wildcards *) and/or by tag.
#
# This configuration is applied after all rules files have been loaded, including
# their overrides, and will take precedence over the enabled/disabled configuration
# specified or overridden in the rules files.
#
# The ordering matters and selections are evaluated in order. For instance, if you
# need to only enable a rule you would first disable all of them and then only
# enable what you need, regardless of the enabled status in the files.
#
# --- [Examples]
#
# Only enable two rules:
#
# rules:
#   - disable:
#       rule: "*"
#   - enable:
#       rule: Netcat Remote Code Execution in Container
#   - enable:
#       rule: Delete or rename shell history
#
# Disable all rules with a specific tag:
#
# rules:
#   - disable:
#       tag: network
#

################
# Falco engine #
################

# [Stable] `engine`
#
# --- [Description]
#
# Falco supports different engines to generate events.
# Choose the appropriate engine kind based on your system's configuration and requirements.
#
# Available engines:
# - `kmod`: Kernel Module (Kernel Module)
# - `ebpf`: eBPF (eBPF probe)
# - `modern_ebpf`: Modern eBPF (CO-RE eBPF probe)
# - `gvisor`: gVisor (gVisor sandbox)
# - `replay`: Replay a scap trace file
# - `nodriver`: No driver is injected into the system.
#   This is useful to debug and to run plugins with 'syscall' source.
#
# Only one engine can be specified in the `kind` key.
# Moreover, for each engine multiple options might be available,
# grouped under engine-specific configuration keys.
# Some of them deserve an in-depth description:
#
################### `buf_size_preset`
#
# --- [Description]
#
# The syscall buffer index determines the size of the shared space between Falco
# and its drivers. This shared space serves as a temporary storage for syscall
# events, allowing them to be transferred from the kernel to the userspace
# efficiently. The buffer size for each online CPU is determined by the buffer
# index, and each CPU has its own dedicated buffer. Adjusting this index allows
# you to control the overall size of the syscall buffers.
#
# --- [Usage]
#
# The index 0 is reserved, and each subsequent index corresponds to an
# increasing size in bytes. For example, index 1 corresponds to a size of 1 MB,
# index 2 corresponds to 2 MB, and so on:
#
# [(*), 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB]
#   ^    ^     ^     ^     ^     ^      ^      ^       ^       ^       ^
#   |    |     |     |     |     |      |      |       |       |       |
#   0    1     2     3     4     5      6      7       8       9       10
#
#
# The buffer dimensions in bytes are determined by the following requirements:
# (1) a power of 2.
# (2) a multiple of your system_page_dimension.
# (3) greater than `2 * (system_page_dimension).
#
# The buffer size constraints may limit the usability of certain indexes. Let's
# consider an example to illustrate this:
#
# If your system has a page size of 1 MB, the first available buffer size would
# be 4 MB because 2 MB is exactly equal to 2 * (system_page_size), which is not
# sufficient as we require more than 2 * (system_page_size). In this example, it
# is evident that if the page size is 1 MB, the first index that can be used is 3.
#
# However, in most cases, these constraints do not pose a limitation, and all
# indexes from 1 to 10 can be used. You can check your system's page size using
# the Falco `--page-size` command-line option.
# 
# --- [Suggestions]
#
# The buffer size was previously fixed at 8 MB (index 4). You now have the
# option to adjust the size based on your needs. Increasing the size, such as to
# 16 MB (index 5), can reduce syscall drops in heavy production systems, but may
# impact performance. Decreasing the size can speed up the system but may
# increase syscall drops. It's important to note that the buffer size is mapped
# twice in the process' virtual memory, so a buffer of 8 MB will result in a 16
# MB area in virtual memory. Use this parameter with caution and only modify it
# if the default size is not suitable for your use case.
#
################### `drop_failed_exit`
#
# --- [Description]
#
# Enabling this option in Falco allows it to drop failed system call exit events
# in the kernel drivers before pushing them onto the ring buffer. This
# optimization can result in lower CPU usage and more efficient utilization of
# the ring buffer, potentially reducing the number of event losses. However, it
# is important to note that enabling this option also means sacrificing some
# visibility into the system.
#
################### `cpus_for_each_buffer` (modern_ebpf only)
#
# --- [Description]
#
# The modern_bpf driver in Falco utilizes the new BPF ring buffer, which has a
# different memory footprint compared to the current BPF driver that uses the
# perf buffer. The Falco core maintainers have discussed the differences and
# their implications, particularly in Kubernetes environments where limits need
# to be carefully set to avoid interference with the Falco daemonset deployment
# from the OOM killer. Based on guidance received from the kernel mailing list,
# it is recommended to assign multiple CPUs to one buffer instead of allocating
# a buffer for each CPU individually. This helps optimize resource allocation
# and prevent potential issues related to memory usage.
#
# This is an index that controls how many CPUs you want to assign to a single
# syscall buffer (ring buffer). By default, for modern_bpf every syscall buffer
# is associated to 2 CPUs, so the mapping is 1:2. The modern BPF probe allows
# you to choose different mappings, for example, changing the value to `1`
# results in a 1:1 mapping and would mean one syscall buffer for each CPU (this
# is the default for the `bpf` driver).
#
# --- [Usage]
#
# You can choose an index from 0 to MAX_NUMBER_ONLINE_CPUs to set the dimension
# of the syscall buffers. The value 0 represents a single buffer shared among
# all online CPUs. It serves as a flexible option when the exact number of
# online CPUs is unknown. Here's an example to illustrate this:
#
# Consider a system with 7 online CPUs:
#
#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
#
# - `1` means a syscall buffer for each CPU so 7 buffers
#
#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
#                   |     |  |        |  |  |  |
#       BUFFERs     0     1  2        3  4  5  6
#
# - `2` (Default value) means a syscall buffer for each CPU pair, so 4 buffers
#
#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
#                   |     |  |        |  |  |  |
#       BUFFERs     0     0  1        1  2  2  3
#
# Please note that in this example, there are 4 buffers in total. Three of the
# buffers are associated with pairs of CPUs, while the last buffer is mapped to
# a single CPU. This arrangement is necessary because we have an odd number of
# CPUs.
#
# - `0` or `MAX_NUMBER_ONLINE_CPUs` mean a syscall buffer shared between all
#   CPUs, so 1 buffer
#
#          CPUs     0  X  2  3  X  X  6  7  8  9   (X means offline CPU)
#                   |     |  |        |  |  |  |
#       BUFFERs     0     0  0        0  0  0  0
#
# Moreover, you have the option to combine this parameter with
# `buf_size_preset` index. For instance, you can create a large shared
# syscall buffer of 512 MB (using buf_size_preset=10) that is
# allocated among all the online CPUs.
#
# --- [Suggestions]
#
# The default choice of index 2 (one syscall buffer for each CPU pair) was made
# because the modern bpf probe utilizes a different memory allocation strategy
# compared to the other two drivers (bpf and kernel module). However, you have
# the flexibility to experiment and find the optimal configuration for your
# system.
# 
# When considering a fixed buf_size_preset and a fixed buffer dimension:
# - Increasing this configs value results in lower number of buffers and you can
#   speed up your system and reduce memory usage
# - However, using too few buffers may increase contention in the kernel,
#   leading to a slowdown.
# 
# If you have low event throughputs and minimal drops, reducing the number of
# buffers (higher `cpus_for_each_buffer`) can lower the memory footprint.

# Falco plugins #
#################

# [Stable] `load_plugins` and `plugins`
#
# --- [Description]
#
# Falco plugins enable integration with other services in your ecosystem.
# They allow Falco to extend its functionality and leverage data sources such as
# Kubernetes audit logs or AWS CloudTrail logs. This enables Falco to perform
# fast on-host detections beyond syscalls and container events. The plugin
# system will continue to evolve with more specialized functionality in future
# releases.
#
# Please refer to the plugins repo at
# https://github.com/falcosecurity/plugins/blob/master/plugins/ for detailed
# documentation on the available plugins. This repository provides comprehensive
# information about each plugin and how to utilize them with Falco.
#
# Please note that if your intention is to enrich Falco syscall logs with fields
# such as `k8s.ns.name`, `k8s.pod.name`, and `k8s.pod.*`, you do not need to use
# the `k8saudit` plugin. This information is automatically extracted from
# the container runtime socket. The `k8saudit` plugin is specifically designed
# to integrate with Kubernetes audit logs and is not required for basic enrichment
# of syscall logs with Kubernetes-related fields.
#
# --- [Usage]
#
# Disabled by default, indicated by an empty `load_plugins` list. Each plugin meant
# to be enabled needs to be listed as explicit list item.
# 
# For example, if you want to use the `k8saudit` plugin,

# load_plugins: [k8saudit, json]
load_plugins: []

# Customize subsettings for each enabled plugin. These settings will only be

# Falco outputs settings #
##########################

# [Stable] `time_format_iso_8601`
#
# When enabled, Falco will display log and output messages with times in the ISO
# 8601 format. By default, times are shown in the local time zone determined by
# the /etc/localtime configuration.
time_format_iso_8601: false

# [Incubating] `buffer_format_base64`
#
# When enabled, Falco will output data buffer with base64 encoding. This is useful
# for encoding binary data that needs to be used over media designed to consume
# this format.
buffer_format_base64: false

# [Stable] `priority`
#
# Any rule with a priority level more severe than or equal to the specified
# minimum level will be loaded and run by Falco. This allows you to filter and
# control the rules based on their severity, ensuring that only rules of a
# certain priority or higher are active and evaluated by Falco. Supported
# levels: "emergency", "alert", "critical", "error", "warning", "notice",
# "info", "debug"
priority: debug

# [Stable] `json_output`
#
# When enabled, Falco will output alert messages and rules file
# loading/validation results in JSON format, making it easier for downstream
# programs to process and consume the data. By default, this option is disabled.
json_output: false

# [Stable] `json_include_output_property`
#
# When using JSON output in Falco, you have the option to include the "output"
# property itself in the generated JSON output. The "output" property provides
# additional information about the purpose of the rule. To reduce the logging
# volume, it is recommended to turn it off if it's not necessary for your use
# case.
json_include_output_property: true

# [Incubating] `json_include_message_property`
#
# When using JSON output in Falco, you have the option to include the formatted
# rule output without timestamp or priority. For instance, if a rule specifies
# an "output" property like "Opened process %proc.name" the "message" field will
# only contain "Opened process bash" whereas the "output" field will contain more
# information.
json_include_message_property: false

# [Stable] `json_include_tags_property`
#
# When using JSON output in Falco, you have the option to include the "tags"
# field of the rules in the generated JSON output. The "tags" field provides
# additional metadata associated with the rule. To reduce the logging volume,
# if the tags associated with the rule are not needed for your use case or can
# be added at a later stage, it is recommended to turn it off.
json_include_tags_property: true

# [Stable] `buffered_outputs`
#
# Enabling buffering for the output queue can offer performance optimization,
# efficient resource usage, and smoother data flow, resulting in a more reliable
# output mechanism. By default, buffering is disabled (false).
buffered_outputs: false

# [Incubating] `rule_matching`
#
# The `rule_matching` configuration key's values are:
#  - `first`: Falco stops checking conditions of rules against upcoming event
#    at the first matching rule
#  - `all`: Falco will continue checking conditions of rules even if a matching 
#    one was already found
#
# Rules conditions are evaluated in the order they are defined in the rules files.
# For this reason, when using `first` as value, only the first defined rule will 
# trigger, possibly shadowing other rules.
# In case `all` is used as value, rules still trigger in the order they were
# defined.
# 
# Effectively, with this setting, it is now possible to apply multiple rules that match
# the same event type. This eliminates concerns about rule prioritization based on the
# "first match wins" principle. However, enabling the `all` matching option may result in
# a performance penalty. We recommend carefully testing this alternative setting before
# deploying it in production.
rule_matching: first

# [Stable] `outputs_queue`
#
# Falco utilizes tbb::concurrent_bounded_queue for handling outputs, and this parameter
# allows you to customize the queue capacity. Please refer to the official documentation:
# https://oneapi-src.github.io/oneTBB/main/tbb_userguide/Concurrent_Queue_Classes.html.
# On a healthy system with optimized Falco rules, the queue should not fill up.
# If it does, it is most likely happening due to the entire event flow being too slow,
# indicating that the server is under heavy load.
# 
# `capacity`: the maximum number of items allowed in the queue is determined by this value. 
# Setting the value to 0 (which is the default) is equivalent to keeping the queue unbounded. 
# In other words, when this configuration is set to 0, the number of allowed items is 
# effectively set to the largest possible long value, disabling this setting.
# 
# In the case of an unbounded queue, if the available memory on the system is consumed, 
# the Falco process would be OOM killed. When using this option and setting the capacity, 
# the current event would be dropped, and the event loop would continue. This behavior mirrors 
# kernel-side event drops when the buffer between kernel space and user space is full.
outputs_queue:
  capacity: 0

# [Sandbox] `append_output`
#
# Add information to the Falco output.
# With this setting you can add more information to the Falco output message, customizable by
# rule, tag or source.
# You can also add additional data that will appear in the output_fields property
# of JSON formatted messages or gRPC output but will not be part of the regular output message.
# This allows you to add custom fields that can help you filter your Falco events without
# polluting the message text.
#
# Each append_output entry has an optional `match` map which specifies which rules will be
# affected.
# `match`:
#   `rule`: append output only to a specific rule
#   `source`: append output only to a specific source
#   `tags`: append output only to rules that have all of the specified tags
# If none of the above are specified (or `match` is omitted)
# output is appended to all events.
# If more than one match condition is specified output will be appended to events 
# that match all conditions.
# And several options to add output:
#   `extra_output`: add output to the Falco message
#   `extra_fields`: add new fields to the JSON output and structured output, which will not
#             affect the regular Falco message in any way. These can be specified as a
#             custom name with a custom format or as any supported field
#             (see: https://falco.org/docs/reference/rules/supported-fields/)
#
# Example:
# 
# append_output:
#   - match:
#       source: syscall
#     extra_output: "on CPU %evt.cpu"
#     extra_fields:
#       - home_directory: "${HOME}"
#       - evt.hostname
#
# In the example above every event coming from the syscall source will get an extra message
# at the end telling the CPU number. In addition, if `json_output` is true, in the "output_fields"
# property you will find three new ones: "evt.cpu", "home_directory" which will contain the value of the
# environment variable $HOME, and "evt.hostname" which will contain the hostname.

# Falco exposed services #
##########################

# [Stable] `grpc`
#
# Falco provides support for running a gRPC server using two main binding types:
# 1. Over the network with mandatory mutual TLS authentication (mTLS), which
#    ensures secure communication
# 2. Local Unix socket binding with no authentication. By default, the
#    gRPCserver in Falco is turned off with no enabled services (see
#    `grpc_output`setting). 
#
# To configure the gRPC server in Falco, you can make the following changes to
# the options:
#
# - Uncomment the relevant configuration options related to the gRPC server.
# - Update the paths of the generated certificates for mutual TLS authentication
#   if you choose to use mTLS.
# - Specify the address to bind and expose the gRPC server.
# - Adjust the threadiness configuration to control the number of threads and
#   contexts used by the server.
#
# Keep in mind that if any issues arise while creating the gRPC server, the
# information will be logged, but it will not stop the main Falco daemon.

# [Stable] `webserver`
#
# Falco supports an embedded webserver that runs within the Falco process,
# providing a lightweight and efficient way to expose web-based functionalities
# without the need for an external web server. The following endpoints are
# exposed:
# - /healthz: designed to be used for checking the health and availability of
#   the Falco application (the name of the endpoint is configurable).
# - /versions: responds with a JSON object containing the version numbers of the
#   internal Falco components (similar output as `falco --version -o
#   json_output=true`).
#
# Please note that the /versions endpoint is particularly useful for other Falco
# services, such as `falcoctl`, to retrieve information about a running Falco
# instance. If you plan to use `falcoctl` locally or with Kubernetes, make sure
# the Falco webserver is enabled.
#
# The behavior of the webserver can be controlled with the following options,
# which are enabled by default:
#
# The `ssl_certificate` option specifies a combined SSL certificate and
# corresponding key that are contained in a single file. You can generate a
# key/cert as follows:
#
# $ openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out

# [Stable] `output_timeout`
#
# Generates Falco operational logs when `log_level=notice` at minimum
#
# A timeout error occurs when a process or operation takes longer to complete
# than the allowed or expected time limit. In the context of Falco, an output
# timeout error refers to the situation where an output channel fails to deliver
# an alert within a specified deadline. Various reasons, such as network issues,
# resource constraints, or performance bottlenecks can cause timeouts.
#
# The `output_timeout` parameter specifies the duration, in milliseconds, to
# wait before considering the deadline exceeded. By default, the timeout is set
# to 2000ms (2 seconds), meaning that the consumer of Falco outputs can block
# the Falco output channel for up to 2 seconds without triggering a timeout
# error.
#
# Falco actively monitors the performance of output channels. With this setting
# the timeout error can be logged, but please note that this requires setting
# Falco's operational logs `log_level` to a minimum of `notice`.
#
# It's important to note that Falco outputs will not be discarded from the
# output queue. This means that if an output channel becomes blocked
# indefinitely, it indicates a potential issue that needs to be addressed by the
# user.
output_timeout: 2000

# [Stable] `syscall_event_timeouts`
#
# Generates Falco operational logs when `log_level=notice` at minimum
#
# Falco utilizes a shared buffer between the kernel and userspace to receive
# events, such as system call information, in userspace. However, there may be
# cases where timeouts occur in the underlying libraries due to issues in
# reading events or the need to skip a particular event. While it is uncommon
# for Falco to experience consecutive event timeouts, it has the capability to
# detect such situations. You can configure the maximum number of consecutive
# timeouts without an event after which Falco will generate an alert, but please
# note that this requires setting Falco's operational logs `log_level` to a
# minimum of `notice`. The default value is set to 1000 consecutive timeouts
# without receiving any events. The mapping of this value to a time interval
# depends on the CPU frequency.
syscall_event_timeouts:

# [Stable] `syscall_event_drops` -> [CHANGE NOTICE] Automatic notifications will be simplified in Falco 0.38! If you depend on the detailed drop counters payload, use 'metrics.output_rule' along with 'metrics.kernel_event_counters_enabled' instead
#
# Generates "Falco internal: syscall event drop" rule output when `priority=debug` at minimum
#
# --- [Description]
#
# Falco uses a shared buffer between the kernel and userspace to pass system
# call information. When Falco detects that this buffer is full and system calls
# have been dropped, it can take one or more of the following actions:
#   - ignore: do nothing (default when list of actions is empty)
#   - log: log a DEBUG message noting that the buffer was full
#   - alert: emit a Falco alert noting that the buffer was full
#   - exit: exit Falco with a non-zero rc
#
# Notice it is not possible to ignore and log/alert messages at the same time.
#
# The rate at which log/alert messages are emitted is governed by a token
# bucket. The rate corresponds to one message every 30 seconds with a burst of
# one message (by default).
#
# The messages are emitted when the percentage of dropped system calls with
# respect the number of events in the last second is greater than the given
# threshold (a double in the range [0, 1]). If you want to be alerted on any
# drops, set the threshold to 0.
#
# For debugging/testing it is possible to simulate the drops using the
# `simulate_drops: true`. In this case the threshold does not apply.
#
# --- [Usage]
#
# Enabled by default, but requires Falco rules config `priority` set to `debug`.
# Emits a Falco rule named "Falco internal: syscall event drop" as many times in
# a given time period as dictated by the settings. Statistics here reflect the
# delta in a 1s time period.
#
# If instead you prefer periodic metrics of monotonic counters at a regular
# interval, which include syscall drop statistics and additional metrics,
# explore the `metrics` configuration option.

# Generates "Falco internal: metrics snapshot" rule output when `priority=info` at minimum
# By selecting `output_file`, equivalent JSON output will be appended to a file.
#
# periodic metric snapshots (including stats and resource utilization) captured
# at regular intervals
#
# --- [Warning]
#
# Due to a regression (https://github.com/falcosecurity/falco/issues/2821) some metrics
# like `falco.host_num_cpus` or `falco.start_ts` will not be available when you use
# source plugins (like k8saudit).
#
# --- [Description]
#
# Consider these key points about the `metrics` feature in Falco:
#
# - It introduces a redesigned stats/metrics system.
# - Native support for resource utilization metrics and specialized performance
#   metrics.
# - Metrics are emitted as monotonic counters at predefined intervals
#   (snapshots).
# - All metrics are consolidated into a single log message, adhering to the
#   established rules schema and naming conventions.
# - Additional info fields complement the metrics and facilitate customized
#   statistical analyses and correlations.
# - The metrics framework is designed for easy future extension.
#
# The `metrics` feature follows a specific schema and field naming convention.
# All metrics are collected as subfields under the `output_fields` key, similar
# to regular Falco rules. Each metric field name adheres to the grammar used in
# Falco rules. There are two new field classes introduced: `falco.` and `scap.`.
# The `falco.` class represents userspace counters, statistics, resource
# utilization, or useful information fields. The `scap.` class represents
# counters and statistics mostly obtained from Falco's kernel instrumentation
# before events are sent to userspace, but can include scap userspace stats as
# well.
#
# It's important to note that the output fields and their names can be subject
# to change until the metrics feature reaches a stable release.
# In addition, the majority of fields represent an instant snapshot, with the
# exception of event rates per second and drop percentage stats. These values
# are computed based on the delta between two snapshots.
#
# To customize the hostname in Falco, you can set the environment variable
# `FALCO_HOSTNAME` to your desired hostname. This is particularly useful in
# Kubernetes deployments where the hostname can be set to the pod name.
#
# --- [Usage]
#
# `enabled`: Disabled by default.
#
# `interval`: The stats interval in Falco follows the time duration definitions
# used by Prometheus.
# https://prometheus.io/docs/prometheus/latest/querying/basics/#time-durations
#
# Time durations are specified as a number, followed immediately by one of the
# following units:
# 
# ms - millisecond
# s - second
# m - minute
# h - hour
# d - day - assuming a day has always 24h
# w - week - assuming a week has always 7d
# y - year - assuming a year has always 365d
#
# Example of a valid time duration: 1h30m20s10ms
#
# A minimum interval of 100ms is enforced for metric collection. However, for
# production environments, we recommend selecting one of the following intervals
# for optimal monitoring:
# 
# 15m
# 30m
# 1h
# 4h
# 6h
#
# `output_rule`: To enable seamless metrics and performance monitoring, we
# recommend emitting metrics as the rule "Falco internal: metrics snapshot".
# This option is particularly useful when Falco logs are preserved in a data
# lake. Please note that to use this option, the Falco rules config `priority`
# must be set to `info` at a minimum.
#
# `output_file`: Append stats to a `jsonl` file. Use with caution in production
# as Falco does not automatically rotate the file. It can be used in combination
# with `output_rule`.
#
# `rules_counters_enabled`: Emit counts for each rule.
#
# `resource_utilization_enabled`: Emit CPU and memory usage metrics. CPU usage
# is reported as a percentage of one CPU and can be normalized to the total
# number of CPUs to determine overall usage. Memory metrics are provided in raw
# units (`kb` for `RSS`, `PSS` and `VSZ` or `bytes` for `container_memory_used`)
# and can be uniformly converted to megabytes (MB) using the
# `convert_memory_to_mb` functionality. In environments such as Kubernetes when 
# deployed as daemonset, it is crucial to track Falco's container memory usage. 
# To customize the path of the memory metric file, you can create an environment 
# variable named `FALCO_CGROUP_MEM_PATH` and set it to the desired file path. By 
# default, Falco uses the file `/sys/fs/cgroup/memory/memory.usage_in_bytes` to 
# monitor container memory usage, which aligns with Kubernetes' 
# `container_memory_working_set_bytes` metric. Finally, we emit the overall host 
# CPU and memory usages, along with the total number of processes and open file 
# descriptors (fds) on the host, obtained from the proc file system unrelated to 
# Falco's monitoring. These metrics help assess Falco's usage in relation to the 
# server's workload intensity.
#
# `state_counters_enabled`: Emit counters related to Falco's state engine, including 
# added, removed threads or file descriptors (fds), and failed lookup, store, or 
# retrieve actions in relation to Falco's underlying process cache table (threadtable). 
# We also log the number of currently cached containers if applicable.
#
# `kernel_event_counters_enabled`: Emit kernel side event and drop counters, as
# an alternative to `syscall_event_drops`, but with some differences. These
# counters reflect monotonic values since Falco's start and are exported at a
# constant stats interval.
#
# `kernel_event_counters_per_cpu_enabled`: Detailed kernel event and drop counters
# per CPU. Typically used when debugging and not in production.
#
# `libbpf_stats_enabled`: Exposes statistics similar to `bpftool prog show`,
# providing information such as the number of invocations of each BPF program
# attached by Falco and the time spent in each program measured in nanoseconds.
# To enable this feature, the kernel must be >= 5.1, and the kernel
# configuration `/proc/sys/kernel/bpf_stats_enabled` must be set. This option,
# or an equivalent statistics feature, is not available for non `*bpf*` drivers.
# Additionally, please be aware that the current implementation of `libbpf` does
# not support granularity of statistics at the bpf tail call level.
#
# `include_empty_values`: When the option is set to true, fields with an empty
# numeric value will be included in the output. However, this rule does not
# apply to high-level fields such as `n_evts` or `n_drops`; they will always be
# included in the output even if their value is empty. This option can be
# beneficial for exploring the data schema and ensuring that fields with empty
# values are included in the output.
#
# `plugins_metrics_enabled`: Falco can now expose your custom plugins' 
# metrics. Please note that if the respective plugin has no metrics implemented, 
# there will be no metrics available. In other words, there are no default or 
# generic plugin metrics at this time. This may be subject to change.
#
# If metrics are enabled, the web server can be configured to activate the
# corresponding Prometheus endpoint using `webserver.prometheus_metrics_enabled`.
# Prometheus output can be used in combination with the other output options.
#
# todo: syscall_counters_enabled option

# Falco performance tuning (advanced) #
#######################################

# [Stable] `base_syscalls`, use with caution, read carefully
#
# --- [Description]
#
# This option configures the set of syscalls that Falco traces.
#
# --- [Falco's State Engine]
#
# Falco requires a set of syscalls to build up state in userspace. For example,
# when spawning a new process or network connection, multiple syscalls are
# involved. Furthermore, properties of a process during its lifetime can be
# modified by syscalls. Falco accounts for this by enabling the collection of
# additional syscalls than the ones defined in the rules and by managing a smart
# process cache table in userspace. Processes are purged from this table when a
# process exits.
#
# By default, with
#   ```
#   base_syscalls.custom_set = []
#   base_syscalls.repair = false
#   ```
# Falco enables tracing for a syscall set gathered: (1) from (enabled) Falco
#   rules (2) from a static, more verbose set defined in
#   `libsinsp::events::sinsp_state_sc_set` in
#   libs/userspace/libsinsp/events/sinsp_events_ppm_sc.cpp This allows Falco to
#   successfully build up it's state engine and life-cycle management.
#
# If the default behavior described above does not fit the user's use case for
# Falco, the `base_syscalls` option allows for finer end-user control of
# syscalls traced by Falco.
#
# --- [base_syscalls.all]
#
# `base_syscalls.all` enables monitoring of all events supported by Falco and
# defined in rules and configs.
# By default some events, such as `write`, are ignored (run `falco -i` to get
# the full list) unless base_syscalls.all is true.
# This option may negatively impact performance.
#
# --- [base_syscalls.custom_set]
#
# CAUTION: Misconfiguration of this setting may result in incomplete Falco event
# logs or Falco being unable to trace events entirely.
#
# `base_syscalls.custom_set` allows the user to explicitly define an additional
# set of syscalls to be traced in addition to the syscalls from each enabled
# Falco rule.
#
# This is useful in lowering CPU utilization and further tailoring Falco to
# specific environments according to your threat model and budget constraints.
#
# --- [base_syscalls.repair]
#
# `base_syscalls.repair` is an alternative to Falco's default state engine
# enforcement. When enabled, this option is designed to (1) ensure that Falco's
# state engine is correctly and successfully built-up (2) be the most system
# resource-friendly by activating the least number of additional syscalls
# (outside of those enabled for enabled rules)
#
# Setting `base_syscalls.repair` to `true` allows Falco to automatically
# configure what is described in the [Suggestions] section below.
#
# `base_syscalls.repair` can be enabled with an empty custom set, meaning with
# the following,
#   ```
#   base_syscalls.custom_set = []
#   base_syscalls.repair = true
#   ```
# Falco enables tracing for a syscall set gathered: (1) from (enabled) Falco
#   rules (2) from minimal set of additional syscalls needed to "repair" the
#   state engine and properly log event conditions specified in enabled Falco
#   rules
#
# --- [Usage]
#
# List of system calls names (<syscall-name>), negative ("!<syscall-name>")
# notation supported.
#
# Example: base_syscalls.custom_set: [<syscall-name>, <syscall-name>,
# "!<syscall-name>"] base_syscalls.repair: <bool>
#
# We recommend to only exclude syscalls, e.g. "!mprotect" if you need a fast
# deployment update (overriding rules), else remove unwanted syscalls from the
# Falco rules.
#
# Passing `-o "log_level=debug" -o "log_stderr=true" --dry-run` to Falco's cmd
# args will print the final set of syscalls to STDOUT.
#
# --- [Suggestions]
#
# NOTE: setting `base_syscalls.repair: true` automates the following suggestions
# for you.
#
# These suggestions are subject to change as Falco and its state engine evolve.
#
# For execve* events: Some Falco fields for an execve* syscall are retrieved
# from the associated `clone`, `clone3`, `fork`, `vfork` syscalls when spawning
# a new process. The `close` syscall is used to purge file descriptors from
# Falco's internal thread / process cache table and is necessary for rules
# relating to file descriptors (e.g. open, openat, openat2, socket, connect,
# accept, accept4 ... and many more)
#
# Consider enabling the following syscalls in `base_syscalls.custom_set` for
# process rules: [clone, clone3, fork, vfork, execve, execveat, close]
#
# For networking related events: While you can log `connect` or `accept*`
# syscalls without the socket syscall, the log will not contain the ip tuples.
# Additionally, for `listen` and `accept*` syscalls, the `bind` syscall is also
# necessary.
#
# We recommend the following as the minimum set for networking-related rules:
# [clone, clone3, fork, vfork, execve, execveat, close, socket, bind,
# getsockopt]
#
# Lastly, for tracking the correct `uid`, `gid` or `sid`, `pgid` of a process
# when the running process opens a file or makes a network connection, consider
# adding the following to the above recommended syscall sets: ... setresuid,
# setsid, setuid, setgid, setpgid, setresgid, setsid, capset, chdir, chroot,
# fchdir ...
base_syscalls:
  custom_set: []

# `thread_table_size`
#
# Set the maximum number of entries (the absolute maximum value can only be MAX UINT32) 
# for Falco's internal threadtable (process cache). Please note that Falco operates at a 
# granular level, focusing on individual threads. Falco rules reference the thread leader 
# as the process. The size of the threadtable should typically be much higher than the 
# number of currently alive processes. The default value should work well on modern 
# infrastructures and be sufficient to absorb bursts.
#
# Reducing its size can help in better memory management, but as a consequence, your 
# process tree may be more frequently disrupted due to missing threads. You can explore 
# `metrics.state_counters_enabled` to measure how the internal state handling is performing,

# [Incubating] `container_engines`
#
# This option allows you to explicitly enable or disable API lookups against container 
# runtime sockets for each supported container runtime. 
# Access to these sockets enables Falco to retrieve container and Kubernetes fields, 
# helping identify workload owners in modern containerized environments. 
# Refer to the fields docs:
# 
# - [Kubernetes fields](https://falco.org/docs/reference/rules/supported-fields/#field-class-k8s)
# - [Container fields](https://falco.org/docs/reference/rules/supported-fields/#container)
# 
# Additionally, Falco can use container events as a data source for alerting (evt.type = container).
# 
# For most container engines, you can solely enable or disable them, and Falco will search the 
# default (hard-coded) container runtime socket paths, such as `/var/run/docker.sock` for Docker.
#
# However, for Kubernetes settings, you can customize the CRI socket paths:
# 
# - `container_engines.cri.sockets`: Pass a list of container runtime sockets.
# - `container_engines.cri.disable_async`: Since API lookups may not always be quick or 
# perfect, resulting in empty fields for container metadata, you can use this option option 
# to disable asynchronous fetching. Note that missing fields may still occasionally occur.
# 
# The equivalent (stable) CLI args are `--cri` or `--disable-cri-async`.
