SUPPORTED CONFIGURATION KEYS
Both configuration directives and commandline switches are listed below.
A configuration consists of key/value pairs, separated by the ':' char.
Starting a line with the '!' symbol, makes the whole line to be ignored
by the interpreter, making it a comment. Please also refer to QUICKSTART
document and the 'examples/' sub-tree for some examples.
Directives are sometimes grouped, like sql_table and print_output_file:
this is to stress if multiple plugins are running as part of the same
daemon instance, such directives must be casted to the plugin they refer
to - in order to prevent undesired inheritance effects. In other words,
grouped directives share the same field in the configuration structure.

FOREWORDS: Individual IP packets are uniquely identified by their header field values (a
rather large set of primitives!). Same applies to uni-directional IP flows, as
they have at least enough information to discriminate where packets are coming
from and going to. Aggregates are instead used for the sole purpose of IP
accounting and hence can be identified by an arbitrary set of primitives.
The process to create an aggregate starting from IP packets or flows is: (a)
select only the primitives of interest (generic aggregation), (b) optionally
cast certain primitive values into broader logical entities, ie. IP addresses
into network prefixes or Autonomous System Numbers (spatial aggregation) and
(c) sum aggregate bytes/flows/packets counters when a new tributary IP packet
or flow is captured (temporal aggregation).
DESC: Aggregate captured traffic data by selecting the specified set of primitives.
sum_<primitive> are compound primitives which sum ingress/egress traffic in a
single aggregate; current limit of sum primitives: each sum primitive is mutual
exclusive with any other, sum and non-sum, primitive. The 'none' primitive
allows to make a single grand total aggregate for traffic flowing through.
'tag', 'tag2' and 'label' generates tags when tagging engines (pre_tag_map,
post_tag) are in use. 'class' enables L7 traffic classification.
NOTES: * List of the aggregation primitives available to each specific pmacct daemon,
along with their description, is available via -a command-line option, ie.
"pmacctd -a".
* Some primitives (ie. tag2, timestamp_start, timestamp_end) are not part of
any default SQL table schema shipped. Always check out documentation related
to the RDBMS in use (ie. 'sql/README.mysql') which will point you to extra
primitive-related documentation, if required.
* peer_src_ip, peer_dst_ip: two primitives with an obscure name conceived to
be as generic as possible due to the many different use-cases around them:
peer_src_ip is the IP address of the node exporting NetFlow/IPFIX or sFlow;
peer_dst_ip is the BGP next-hop or IP next-hop (if use_ip_next_hop is set
to true).
* sampling_rate: if counters renormalization (ie. sfacctd_renormalize) is
enabled this field will report a value of one (1); otherwise it will report
the rate that is passed by the protocol or sampling_map. A value of zero (0)
means 'unknown' and hence no rate is applied to original counter values.
* src_std_comm, src_ext_comm, src_lrg_comm, src_as_path are based on reverse
BGP lookups; peer_src_as, src_local_pref and src_med are by default based on
reverse BGP lookups but can be alternatively based on other methods, for
example maps (ie. bgp_peer_src_as_type). Internet traffic is by nature
asymmetric hence reverse BGP lookups must be used with caution (ie. against
own prefixes).
* mpls_label_top, mpls_label_bottom primitives only include the MPLS label
value, stripped of EXP code-points (and BoS flag). Visibiliy in EXP values
can be achieved by defining a custom primitive to extract the full 3 bytes,
ie. 'name=mplsFullTopLabel field_type=70 len=3 semantics=raw' for NetFlow/
IPFIX. On the contrary mpls_label_stack does extract the full 3 bytes.
* mpls_vpn_rd primitive value can be sourced in multiple ways in case of
IPFIX/NFv9. The current preference is: flow_to_rd.map > RD in IPFIX/NFv9
data packet > RD in IPFIX/NFv9 option packets.
* timestamp_start, timestamp_end and timestamp_arrival let pmacct act as a
traffic logger up to the msec level (if reported by the capturing method).
timestamp_start records NetFlow/IPFIX flow start time or observation;
timestamp_end records NetFlow/IPFIX flow end time; timestamp_arrival
records libpcap packet timestamp and sFlow/NetFlow/IPFIX packet arrival
time at the collector. Historical accounting (enabled by the *_history
config directives, ie. kafka_history) finest granularity for time-bins
is 1 minute: timestamp_start can be used for finer greater granularitiies,
ie. second (timestamps_secs set to true) or sub-second.
* tcpflags: in pmacctd, uacctd and sfacctd daemons TCP flags are ORed until
the aggregate is flushed - hence emulating the behaviour of NetFlow/IPFIX.
If a flag analysis is needed, packets with different flags (combinations)
should be isolated using a pre_tag_map/pre_tag_filter or aggregate_filter
features (see examples in QUICKSTART and review libpcap filtering syntax
via pcap-filter man page).
* export_proto_seqno reports about export protocol (NetFlow, sFlow, IPFIX)
sequence number and can be very relevant to detect packet loss. nfacctd and
sfacctd do perform simple non-contextual sequencing checks but these are
mainly limited to check out-of-order situations; proper contextual checking
can be performed as part of post-processing. A specific plugin instance,
separate from the main / accounting one, can be configured with 'aggregate:
export_proto_seqno' for the task. An example of a simple check would be to
find min/max sequence numbers, compute their difference and make sure it
does match to the amount of entries in the interval; the check can be then
windowed over time by using timestamps (ie. 'timestamp_export' primitive
and/or *_history config directives).
* timestamp_export is the observation time at the exporter. This is only
relevant in export protocols involving caching, ie. NetFlow/IPFIX. In all
other cases this would not be populated or be equal to timestamp_start.
* In nfacctd, undocumented aggregation primitive class_frame allows to apply
nDPI clssification to NFv9/IPFIX packets with IE 315 (dataLinkFrameSection).
class primitive instead allows to leverage traditional classification using
NetFlow v9/IPFIX IE 94, 95 and 96 (applicationDescription, applicationId
and applicationName).
* vlan / in_vlan / out_vlan: in NetFlow / IPFIX and sFlow, where there is
indication (explicit or implicit, ie. expressing sample direction) of
ingress / egress sampling, 'vlan' checks both cases reporting the VLAN ID
of the first case checked reporting a non-zero ID (ingress > egress); more
intuitively, in_vlan reports ingress VLAN ID if any and out_vlan reports
egress VLAN ID if any.
* srv6_seg_ipv6_list primitive is only available if using an encoding, like
JSON or Avro, that supports complex data (ie. arrays, maps, etc.).
DEFAULT: src_host
KEY: aggregate_primitives [GLOBAL, MAP]
DESC: Expects full pathname to a file containing custom-defined primitives. Once
defined in this file, primitives can be used in 'aggregate' statements. The
feature is currently available only in nfacctd, for NetFlow v9/IPFIX, pmacctd
and uacctd. Examples are available in 'examples/primitives.lst.example'. This
map does not support reloading at runtime.
DEFAULT: none
KEY: aggregate_filter [NO_GLOBAL, NO_UACCTD]
DESC: Per-plugin filtering applied against the original packet or flow. Aggregation
is performed slightly afterwards, upon successful match of this filter.
By binding a filter, in tcpdump syntax, to an active plugin, this directive
allows to select which data has to be delivered to the plugin and aggregated
as specified by the plugin 'aggregate' directive. See the following example:
...
aggregate[inbound]: dst_host
aggregate[outbound]: src_host
aggregate_filter[inbound]: dst net 192.168.0.0/16
aggregate_filter[outbound]: src net 192.168.0.0/16
plugins: memory[inbound], memory[outbound]
...
This directive can be used in conjunction with 'pre_tag_filter' (which, in
turn, allows to filter tags). You will also need to force fragmentation handling
in the specific case in which a) none of the 'aggregate' directives is including
L4 primitives (ie. src_port, dst_port) but b) an 'aggregate_filter' runs a filter
which requires dealing with L4 primitives. For further information, refer to the
'pmacctd_force_frag_handling' directive.
DEFAULT: none
KEY: aggregate_unknown_etype [GLOBAL]
VALUES: [ true | false ]
DESC: By default, Ethernet frames with unknown EtherTypes for which pmacct has not
implemented decoding support are ignored by the aggregation engine. Enabling this
option allows such frames to be aggregated by the available Ethernet L2 header
fields ('src_mac', 'dst_mac', 'vlan', 'cos', 'etype'). This is currently
supported in pmacctd and uacctd; while it only makes ARP packets pass through
in sfacctd.
DEFAULT: false
KEY: dtls_path [GLOBAL]
DESC: Full path to a directory containing files needed to establish a successful DTLS
session (key, certificate and CA file); a key.pem file can be generated with the
"certtool --generate-privkey --outfile key.pem" command-line; a self-signed
cert.pem certificate, having previously created the key, can be generated with
the "certtool --generate-self-signed --load-privkey key.pem --outfile cert.pem"
command-line; the ca-certificates.crt CA file can be copied from (ie. on Debian
or Ubuntu) "/etc/ssl/certs/ca-certificates.crt".
DEFAULT: none
KEY: writer_id_string
DESC: A "writer_id" field is added when sending data onto a Kafka or RabbitMQ broker,
this is meant to add contextual information about the collector producing data
(ie. $proc_name) or the specific batch of data (ie. PID of the writer process,
$writer_pid). Additional static information and separators can be supplied as
part of the string. Some variables are supported:
$proc_name The name of the process producing data. This maps to the plugin
name in case of 'kafka' and 'amqp' plugins and core_proc_name
when the write is made from the Core Process, ie. BGP, BMP and
Streaming Telemetry cases
$writer_pid The PID of the process producing data
$pmacct_build The build version of the collector producing data
Note: The '_' character is part of the variables alphabet not hence it isn't a
valid separator between any two variables and between any variable and static
text. It can only used as part of variables, like the ones defined above, or
static text.
DEFAULT: $proc_name/$writer_pid
KEY: pcap_filter [GLOBAL, PMACCTD_ONLY, ONLY_PMBMPD]
DESC: This filter is global and applied to all incoming packets. It's passed to libpcap
and expects libpcap/tcpdump filter syntax. Being global it doesn't offer a great
flexibility but it's the fastest way to drop unwanted traffic.
DEFAULT: none
KEY: pcap_protocol [GLOBAL, PMACCTD_ONLY]
DESC: If set, specifies a specific packet socket protocol value to limit packet capture
to (for example, 0x0800 = IPv4). This option is only supported if pmacct was built
against a version of libpcap that supports pcap_set_protocol().
DEFAULT: none
KEY: pcap_arista_trailer_offset [GLOBAL, PMACCTD_ONLY]
DESC: Arista does set a trailer structure to convey extra info (ie. output interface, etc.) when
mirroring packets. This knob sets the byte offset from the end of the packet to indicate
where the trailer starts.
DEFAULT: none
KEY: pcap_arista_trailer_flag_value [GLOBAL, PMACCTD_ONLY]
DESC: When 'pcap_arista_trailer_offset' is set, specify the expected value in the arista trailer
flag field that indicates the output interface is present (this varies by chipset).
DEFAULT: 1
KEY: snaplen (-L) [GLOBAL, NO_NFACCTD, NO_SFACCTD]
DESC: Specifies the maximum number of bytes to capture for each packet. This directive has
key importance to both classification and connection tracking engines. In fact, some
protocols (mostly text-based eg.: RTSP, SIP, etc.) benefit of extra bytes because
they give more chances to successfully track data streams spawned by control channel.
But it must be also noted that capturing larger packet portion require more resources.
The right value need to be traded-off. In case classification is enabled, values under
200 bytes are often meaningless. 500-750 bytes are enough even for text based
protocols. Default snaplen value is OK if classification is disabled.
DEFAULT: 128 bytes
KEY: plugins (-P) [GLOBAL]
VALUES: [ memory | print | mysql | pgsql | sqlite3 | nfprobe | sfprobe | tee | amqp | kafka ]
DESC: Plugins to be enabled. memory, print, nfprobe, sfprobe and tee plugins are always
compiled in pmacct executables as they do not have external dependencies. Database
(ie. RDBMS, noSQL) and messaging ones (ie. amqp, kafka) do have external dependencies
and hence are available only if explicitely configured and compiled (see QUICKSTART).
'memory' plugin uses a memory table as backend and a client tool, 'pmacct', can fetch
the memory table content; the memory plugin is only good to prototype solutions, lab
environment without mass traffic generation and small/home production environments.
mysql, pgsql and sqlite3 plugins do output respectively to MySQL (or MariaDB via the
MySQL-compatible C API), PostgreSQL and SQLite 3.x (or BerkeleyDB 5.x via the SQLite
API compiled-in) databases to store data. 'print' plugin prints output data to flat-
files or stdout in JSON, Apache Avro, CSV or tab-spaced encodings. 'amqp' and 'kafka'
plugins allow to output data to RabbitMQ and Kafka brokers respectively. All these
plugins - to output to stdout, files, RDBMS and messaging brokers - are suitable for
production solutions and/or larger scenarios.
'nfprobe' plugin is a NetFlow/IPFIX agent and exports collected data via NetFlow v5/
v9 and IPFIX datagrams to a remote collector. 'sfprobe' plugin is a sFlow agent and
exports collected data via sFlow v5 datagrams to a remote collector. Both 'nfprobe'
and 'sfprobe' plugins can be run only via pmacctd and uacctd daemons (in other words
no collect NetFlow v5 / re-export IPFIX and similar trans-codings are supported).
The 'tee' plugin is a replicator of NetFlow/IPFIX/sFlow data (also transparent); it
can be run only via nfacctd and sfacctd.
Plugins can be either anonymous or named; configuration directives can be global or
bound to a specific plugins when named. An anonymous plugin is declared as 'plugins:
mysql' in the config whereas a named plugin is declared as 'plugins: mysql[name]'.
Then directives can be bound to a specific named plugin as: 'directive[name]: value'.
DEFAULT: memory
KEY: [ nfacctd_pipe_size | sfacctd_pipe_size | pmacctd_pipe_size ] [GLOBAL, NO_UACCTD]
DESC: Defines the size of the kernel socket to read traffic data. The socket is highlighted
below with "XXXX":
XXXX
[network] ----> [kernel] ----> [core process] ----> [plugin] ----> [backend]
[__________pmacct___________]
On Linux systems, if this configuration directive is not specified default socket size
awarded is defined in /proc/sys/net/core/[rw]mem_default ; the maximum configurable
socket size is defined in /proc/sys/net/core/[rw]mem_max instead. Still on Linux, the
"drops" field of /proc/net/udp or /proc/net/udp6 can be checked to ensure its value
is not increasing.
DEFAULT: Operating System default
KEY: [ bgp_daemon_pipe_size | bmp_daemon_pipe_size ] [GLOBAL]
DESC: Defines the size of the kernel socket used for BGP and BMP messaging. The socket is
highlighted below with "XXXX":
XXXX
[network] ----> [kernel] ----> [core process] ----> [plugin] ----> [backend]
[__________pmacct___________]
On Linux systems, if this configuration directive is not specified default socket size
awarded is defined in /proc/sys/net/core/rmem_default ; the maximum configurable socket
size (which can be changed via sysctl) is defined in /proc/sys/net/core/rmem_max
instead.
DEFAULT: Operating System default
KEY: plugin_pipe_size
DESC: Core Process and each of the plugin instances are run into different processes. To
exchange data, they set up a circular queue (home-grown implementation, referred to
as 'pipe') and highlighted below with "XXXX":
XXXX
[network] ----> [kernel] ----> [core process] ----> [plugin] ----> [backend]
[__________pmacct___________]
This directive sets the total size, in bytes, of such queue. Its default size is set
to 4MB. Whenever facing heavy traffic loads, this size can be adjusted to hold more
data. In the following example, the queue between the Core process and the plugin
'test' is set to 10MB:
...
plugins: memory[test]
plugin_pipe_size[test]: 10240000
...
When enabling debug, log messages about obtained and target pipe sizes are printed.
If obtained is less than target, it could mean the maximum socket size granted by
the Operating System has to be increased. On Linux systems default socket size awarded
is defined in /proc/sys/net/core/[rw]mem_default ; the maximum configurable socket
size (which can be changed via sysctl) is defined in /proc/sys/net/core/[rw]mem_max
instead.
In case of data loss messages containing the "missing data detected" string will be
logged - indicating the plugin affected and current settings.
Alternatively see at plugin_pipe_zmq and plugin_pipe_zmq_profile.
DEFAULT: 4MB
KEY: plugin_buffer_size
DESC: By defining the transfer buffer size, in bytes, this directive enables buffering of
data transfers between core process and active plugins. Once a buffer is filled, it
is delivered to the plugin. Setting a larger value may improve throughput (ie. amount
of CPU cycles required to transfer data); setting a smaller value may improve latency,
especially in scenarios with little data influx. It is disabled by default. If used
with the home-grown circular queue implemetation, the value has to be minor/equal to
the size defined by 'plugin_pipe_size' and keeping a ratio between 1:100 and 1:1000
among the two is considered good practice; the circular queue of plugin_pipe_size size
is partitioned in chunks of plugin_buffer_size.
Alternatively see at plugin_pipe_zmq and plugin_pipe_zmq_profile.
DEFAULT: Set to the size of the smallest element to buffer
KEY: plugin_pipe_zmq
VALUES: [ true | false ]
DESC: By defining this directive to 'true', a ZeroMQ queue is used for queueing and data
exchange between the Core Process and the plugins. This is in alternative to the
home-grown circular queue implementation (see plugin_pipe_size description). This
directive, along with all other plugin_pipe_zmq_* directives, can be set globally
or be applied on a per plugin basis (ie. it is a valid scenario, if multiple
plugins are instantiated, that some make use of home-grown queueing, while others
use ZeroMQ based queueing). For a quick comparison: while relying on a ZeroMQ queue
introduces an external dependency, ie. libzmq, it reduces the bare minimum the need
of settings of the home-grown circular queue implementation. See QUICKSTART for
some examples.
DEFAULT: false
KEY: plugin_pipe_zmq_retry
DESC: Defines the interval of time, in seconds, after which a connection to the ZeroMQ
server (Core Process) should be retried by the client (Plugin) after a failure is
detected.
DEFAULT: 60
KEY: plugin_pipe_zmq_profile
VALUES: [ micro | small | medium | large | xlarge ]
DESC: Allows to select some standard buffering profiles. Following are the recommended
buckets in flows/samples/packets per second (the configured buffer value is
reported in brackets and is meant only to facilitate transitioning existing
deployments from plugin_buffer_size):
micro : up to 1K (0KB)
small : from 1K to 10-15K (10KB)
medium : from 10-10K to 100-125K (100KB)
large : from 100-125K to 250K (1MB)
xlarge : from 250K (10MB)
A symptom that the selected profile may be undersized is the missing data warnings
appearing in the logs; a symptom it is oversized instead is the latency in data
being purged out: in fact the buffer has to fill up in order to be released to the
plugin. The amount of flows/samples per second can be estimated as described in Q21
in the FAQS document; 'large' and 'xlarge' (and possibly also 'medium') profiles
may be counter-productive in case of a 'tee' plugin: excessive burstiness may cause
UDP drops due to small default kernel buffers. Should no profile fit the sizing,
the buffering value can be customised using the plugin_buffer_size directive.
DEFAULT: micro
KEY: plugin_pipe_zmq_hwm
DESC: Defines the messages high watermark, that is, "The high water mark is a hard
limit on the maximum number of outstanding messages ZeroMQ shall queue in
memory for any single peer that the specified socket is communicating with. A
value of zero means no limit.". If configured, upon reaching the set watermark
value, exceeding data will be discaded and an error log message will be output.
DEFAULT: 0
KEY: plugin_exit_any
VALUES: [ true | false ]
DESC: Daemons gracefully shut down (core process and all plugins) if either the core
process or all the registered plugins bail out. Setting this to true makes the
daemon to gracefully shut down in case any single one of the plugins bails out
and regardless there may be more plugins still active.
DEFAULT: false
KEY: propagate_signals [GLOBAL]
VALUES: [ true | false ]
DESC: When a signal is sent to the Core Process, propagate it to all active plugins;
this may come handy in scenarios where pmacct is run inside a (Docker) container.
DEFAULT: false
KEY: files_umask
DESC: Defines the mask for newly created files (log, pid, etc.) and their related directory
structure. A mask less than "002" is not accepted due to security reasons.
DEFAULT: 077
KEY: files_uid
DESC: Defines the system user id (UID) for files opened for writing (log, pid, etc.); this
is indeed possible only when running the daemon as super-user. This is also applied
to any intermediary directory structure which might be created. Both user string and
id are valid input.
DEFAULT: Operating System default (current user UID)
KEY: files_gid
DESC: Defines the system group id (GID) for files opened for writing (log, pid, etc.); this
is indeed possible only when running the daemon as super-user; this is also applied
to any intermediary directory structure which might be created. Both group string and
id are valud input.
DEFAULT: Operating System default (current user GID)
KEY: pcap_interface (-i) [GLOBAL, PMACCTD_ONLY]
DESC: Interface on which 'pmacctd' listens. If such directive isn't supplied, a libpcap
function is used to select a valid device. [ns]facctd can catch similar behaviour by
employing the [ns]facctd_ip directives; also, note that this directive is mutually
exclusive with 'pcap_savefile' (-I).
DEFAULT: Interface is selected by by the Operating System
KEY: pcap_interface_wait (-w) [GLOBAL, PMACCTD_ONLY]
VALUES: [ true | false ]
DESC: If set to true, this option causes 'pmacctd' to wait for the listening device to become
available; it will try to open successfully the device each few seconds. Whenever set to
false, 'pmacctd' will exit as soon as any error (related to the listening interface) is
detected.
DEFAULT: false
KEY: pcap_savefile (-I) [GLOBAL, NO_UACCTD, NO_PMBGPD]
DESC: File in libpcap savefile format to read data from (as an alternative to live data
collection). As soon as the daemon processed the file, it exits (unless, in pmacctd,
'pcap_savefile_wait' is specified). The directive is mutually exclusive with reading
live traffic (ie. pcap_interface (-i) for pmacctd, [ns]facctd_ip (-L) and
[ns]facctd_port (-l) for nfacctd and sfacctd respectively, bmp_daemon_ip for pmbmpd).
If using a traffic daemon (ie. nfacctd) with a BMP thread (ie. bmp_daemon: true) and
wanting to feed both with a savefile, only one file can be supplied (that is, only a
single pcap_savefile can be specified in the config): if having multiple files, ie.
one with traffic data and one with BMP data, these can be merged using, for example,
Wireshark which offers options to prepend, merge chronologically and append data.
Note: reading libpcap savefiles does use the cap_next_ex() call which seems not to be
highly portable, ie. a capture produced on a Linux does not always read on a MacOS.
Note: when using home-grown buffering (ie. not ZeroMQ), usleep() calls are placed
upon wrapping-up one buffer and starting up a new one. This may lead to under using
CPU and not the quickest processing experience; if a fastest rate is wanted, switch
buffering to ZeroMQ ('plugin_pipe_zmq: true').
DEFAULT: none
KEY: pcap_savefile_wait (-W) [GLOBAL, NO_UACCTD, NO_PMBGPD]
VALUES: [ true | false ]
DESC: If set to true, this option will cause the daemon to wait indefinitely for a signal
(ie. CTRL-C when not daemonized or 'killall -9 pmacctd' if it is) after being finished
processing the supplied libpcap savefile (pcap_savefile). This is particularly useful
when inserting fixed amounts of data into memory tables.
DEFAULT: false
KEY: pcap_savefile_delay (-Z) [GLOBAL, NO_UACCTD, NO_PMBGPD]
DESC: When reading from a pcap_savefile, sleep for the supplied amount of seconds before
(re)playing the file. For example this is useful to let a BGP session be established
and a RIB be finalised before playing a given file or buy time among replays so for
a dump event to trigger.
DEFAULT: 0
KEY: pcap_savefile_replay (-Y) [GLOBAL, NO_UACCTD, NO_PMBGPD]
DESC: When reading from a pcap_savefile, replay content for the specified amount of times.
Other than for testing in general, this may be useful when playing templated-based
protocols, ie. NetFlow v9/IPFIX, to replay data packets that could not be parsed
the first time due to the template not being sent yet.
DEFAULT: 1
KEY: [ pcap_direction | uacctd_direction ] [GLOBAL, ONLY_PMACCTD, ONLY_UACCTD]
VALUES: [ "in", "out" ]
DESC: Defines the traffic capturing direction with two possible values, "in" and "out". In
pmacctd this is used to 1) determine which primitive to populate, whether in_iface or
out_iface with the pcap_ifindex value and 2) tag / filter data basing on direction in
pre_tag_map. Not all platforms do support pcap_set_direction() and a quick test is to
check if tcpdump, ie. 'tcpdump -i <interface> -Q in', does work as intended. In uacctd
the only functionality is the latter of the two use-cases.
DEFAULT: none
KEY: pcap_ifindex [GLOBAL, PMACCTD_ONLY]
VALUES: [ "sys", "hash", "map", "none" ]
DESC: Defines how to source the ifindex of the capturing interface. If "sys" then a
if_nametoindex() call is triggered to the underlying OS and the result is used; if
"hash" an hashing algorithm is used against the interface name to generate a unique
number per interface; if "map" then ifindex definitions are expected as part of a
pcap_interfaces_map (see below).
DEFAULT: none
KEY: pcap_interfaces_map [GLOBAL, PMACCTD_ONLY, MAP]
DESC: Allows to listen for traffic data on multiple interfaces (compared to pcap_interface
where only a single interface can be defined). The map allows to define also ifindex
and capturing direction on a per-interface basis; to include the computed ifindex in
output data set pcap_ifindex to 'map'. The map can be reloaded at runtime by sending
the daemon a SIGUSR2 signal (ie. "killall -USR2 nfacctd"). Sample map in
examples/pcap_interfaces.map.example .
DEFAULT: none
KEY: promisc (-N) [GLOBAL, PMACCTD_ONLY]
VALUES: [ true | false ]
DESC: If set to true, puts the listening interface in promiscuous mode. It's mostly useful when
running 'pmacctd' in a box which is not a router, for example, when listening for traffic
on a mirroring port.
DEFAULT: true
KEY: imt_path (-p)
DESC: Specifies the full pathname where the memory plugin has to listen for client queries.
When multiple memory plugins are active, each one has to use its own file to communicate
with the client tool. Note that placing these files into a carefully protected directory
(rather than /tmp) is the proper way to control who can access the memory backend.
DEFAULT: /tmp/collect.pipe
KEY: imt_buckets (-b)
DESC: Defines the number of buckets of the memory table which is organized as a chained hash
table. A prime number is highly recommended. Read INTERNALS 'Memory table plugin' chapter
for further details.
DEFAULT: 32771
KEY: imt_mem_pools_number (-m)
DESC: Defines the number of memory pools the memory table is able to allocate; the size of each
pool is defined by the 'imt_mem_pools_size' directive. Here, a value of 0 instructs the
memory plugin to allocate new memory chunks as they are needed, potentially allowing the
memory structure to grow undefinitely. A value > 0 instructs the plugin to not try to
allocate more than the specified number of memory pools, thus placing an upper boundary
to the table size.
DEFAULT: 16
KEY: imt_mem_pools_size (-s)
DESC: Defines the size of each memory pool. For further details read INTERNALS 'Memory table
plugin'. The number of memory pools is defined by the 'imt_mem_pools_number' directive.
DEFAULT: 8192
KEY: syslog (-S) [GLOBAL]
VALUES: [ auth | mail | daemon | kern | user | local[0-7] ]
DESC: Enables syslog logging, using the specified facility.
DEFAULT: none (logging to stderr)
KEY: logfile [GLOBAL]
DESC: Enables logging to a file (bypassing syslog); expected value is a pathname. The target
file can be re-opened by sending a SIGHUP to the daemon so that, for example, logs can
be rotated.
DEFAULT: none (logging to stderr)
KEY: amqp_host
DESC: Defines the AMQP/RabbitMQ broker IP. All amqp_* directives are used by the AMQP plugin
of flow daemons only. Check *_amqp_host out (ie. bgp_daemon_msglog_amqp_host) for the
equivalent directives relevant to other RabbitMQ exports.
DEFAULT: localhost

bmp_daemon_msglog_amqp_host | sfacctd_counter_amqp_host |
telemetry_daemon_msglog_amqp_host | telemetry_dump_amqp_host ] [GLOBAL]
DESC: See amqp_host. bgp_daemon_msglog_amqp_* directives are used by the BGP thread/daemon
to stream data out; bgp_table_dump_amqp_* directives are used by the BGP thread/daemon
to dump data out at regular time intervals; bmp_daemon_msglog_amqp_* directives are
used by the BMP thread/daemon to stream data out; bmp_dump_amqp_* directives are
used by the BMP thread/daemon to dump data out at regular time intervals;
sfacctd_counter_amqp_* directives are used by sfacctd to stream sFlow counter data out;
telemetry_daemon_msglog_amqp_* are used by the Streaming Telemetry thread/daemon to
stream data out; telemetry_dump_amqp_* directives are used by the Streaming Telemetry
thread/daemon to dump data out at regular time intervals.
DEFAULT: See amqp_host
KEY: amqp_vhost
DESC: Defines the AMQP/RabbitMQ server virtual host; see also amqp_host.

DESC: See amqp_passwd; see also bgp_daemon_msglog_amqp_host.
DEFAULT: See amqp_passwd
KEY: amqp_routing_key
DESC: Name of the AMQP routing key to attach to published data. Dynamic names are supported
through the use of variables, which are computed at the moment when data is purged to
the backend. The list of variables supported is:
$peer_src_ip Value of the peer_src_ip primitive of the record being processed.
$tag Value of the tag primitive of the record being processed.
$tag2 Value of the tag2 primitive of the record being processed.
$post_tag Configured value of post_tag.
$post_tag2 Configured value of post_tag2.
See also amqp_host.

DESC: See amqp_routing_key; see also bgp_daemon_msglog_amqp_host. Variables supported by
the configuration directives described in this section:
$peer_src_ip BGP peer IP address (bgp_*) or sFlow agent IP address (sfacctd_*).
$bmp_router BMP peer IP address.
$telemetry_node Streaming Telemetry exporter IP address.
$peer_tcp_port BGP peer TCP port.
$bmp_router_port BMP peer TCP port.
$telemetry_node_port Streaming Telemetry exporter port.
DEFAULT: none
KEY: [ amqp_routing_key_rr | kafka_topic_rr ]
DESC: Performs round-robin load-balancing over a set of AMQP routing keys or Kafka topics.
The base name for the string is defined by amqp_routing_key or kafka_topic. This key
accepts a positive int value. If, for example, amqp_routing_key is set to 'blabla'
and amqp_routing_key_rr to 3 then the AMQP plugin will round robin as follows:
message #1 -> blabla_0, message #2 -> blabla_1, message #3 -> blabla_2, message #4
-> blabla_0 and so forth. This works in the same fashion for kafka_topic. By default
the feature is disabled, meaning all messages are sent to the base AMQP routing key
or Kafka topic (or the default one, if no amqp_routing_key or kafka_topic is being

For Kafka it is adviced to create topics in advance with a tool like kafka-topics.sh
(ie. "kafka-topics.sh --zookeepeer <zookeeper URL> --topic <topic> --create") even
if auto.create.topics.enable is set to true (default) on the broker. This is because
topic creation, especially on distributed systems, may take time and lead to data
loss.

VALUES: [ true | false ]
DESC: Marks messages as persistent and sets Exchange as durable so to prevent data loss
if a RabbitMQ server restarts (it will still be consumer responsibility to declare
the queue durable). Note from RabbitMQ docs: "Marking messages as persistent does
not fully guarantee that a message won't be lost. Although it tells RabbitMQ to
save message to the disk, there is still a short time window when RabbitMQ has
accepted a message and hasn't saved it yet. Also, RabbitMQ doesn't do fsync(2) for
every message -- it may be just saved to cache and not really written to the disk.
The persistence guarantees aren't strong, but it is more than enough for our simple
task queue."; see also amqp_host.

for the connection. 4096 is the minimum size, 2^31-1 is the maximum; it may be needed to
up the value from its default especially when making use of amqp_multi_values which will

KEY: amqp_heartbeat_interval
DESC: Defines the heartbeat interval in order to detect general failures of the RabbitMQ server.
The value is expected in seconds. By default the heartbeat mechanism is disabled with a
value of zero. According to RabbitMQ C API, detection takes place only upon publishing a
JSON message, ie. not at login or if idle. The maximum value supported is INT_MAX (or
2147483647); see also amqp_host.

KEY: kafka_topic
DESC: Name of the Kafka topic to attach to published data. Dynamic names are supported by
kafka_topic through the use of variables, which are computed at the moment when data
is purged to the backend. The list of variables supported by amqp_routing_key:
$peer_src_ip Value of the peer_src_ip primitive of the record being processed.
$tag Value of the tag primitive of the record being processed.
$tag2 Value of the tagw primitive of the record being processed.
$post_tag Configured value of post_tag.
$post_tag2 Configured value of post_tag2.
It is adviced to create topics in advance with a tool like kafka-topics.sh (ie.
"kafka-topics.sh --zookeepeer <zookeeper URL> --topic <topic> --create") even if
auto.create.topics.enable is set to true (default) on the broker. This is because
topic creation, especially on distributed systems, may take time and lead to data
loss.
DEFAULT: 'pmacct.acct'
KEY: kafka_config_file
DESC: Full pathname to a file containing directives to configure librdkafka. All knobs
whose values are string, integer, boolean, CSV are supported. Pointer values, ie.
for setting callbacks, are currently not supported through this infrastructure.
The syntax of the file is CSV and expected in the format: <type, key, value> where
'type' is one of 'global' or 'topic' and 'key' and 'value' are set according to
librdkafka doc https://github.com/edenhill/librdkafka/blob/master/CONFIGURATION.md
Both 'key' and 'value' are passed onto librdkafka without any validation being
performed; the 'value' field can also contain commas no problem as it is also not
parsed. Examples are:
topic, compression.codec, snappy
global, socket.keepalive.enable, true
DEFAULT: none
KEY: kafka_broker_host
DESC: Defines one or multiple, comma-separated, Kafka brokers for the bootstrap process.
If only a single broker IP address is defined then the broker port is read via the
kafka_broker_port config directive (legacy syntax); if multiple brokers are defined
then each broker port, if not left to default 9092, is expected as part of this
directive, for example: "broker1:10000,broker2". When defining multiple brokers,
if the host is IPv4, the value is expected as 'address:port'. If IPv6, it is
expected as '[address]:port' (although when defining a single broker, this is not
required as the IPv6 address is detected and wrapped-around '[' ']' symbols).
Resolvable hostnames are also accepted, if host resolves to multiple addresses it
will round-robin the addresses for each connection attempt. SSL connections can be
configured as "ssl://broker3:9000,ssl://broker2". All kafka_* directives are used
by the Kafka plugin of flow daemons only. Check other *_kafka_broker_host out (ie.
bgp_daemon_msglog_kafka_broker_host) for the equivalent directives relevant to
other Kafka exports.

partition). See also kafka_broker_host.
DEFAULT: -1
KEY: kafka_partition_dynamic

DESC: Enables dynamic Kafka partitioning, ie. data is partitioned according to the value
of the Kafka broker topic partition key. See also kafka_partition_key.
DEFAULT: false
KEY: kafka_partition_key
DESC: Defines the Kafka broker topic partition key. A string of printable characters is
expected as value. Dynamic names are supported through the use of variables, which
are computed at the moment data is purged to the backend. The list of supported
variables follows:
