Django Logging

Welcome to django_logging Documentation!

The django_logging is a powerful yet simple Django package that extends and enhances Python's built-in logging without relying on any third-party libraries. Our goal is to keep things straightforward while providing flexible and customizable logging solutions that are specifically designed for Django applications.

One of the key advantages of django_logging is its seamless integration. Get started with django_logging in your existing projects without refactoring any code. Even if you're already using the built-in logging module, you can instantly upgrade to advanced features with just a simple installation. No extra changes or complicated setup required!

imagine you have a Django package that was developed a few years ago and already uses Python's built-in logging. Refactoring the entire codebase to use another logging package would be a daunting task. But with django_logging, you don't have to worry about that. Simply install django_logging and enjoy all its advanced features with logging each LEVEL in separate files with three extra formats (json, xml, flat) without having to make any changes to your existing code.

Language: Python >= 3.9
Framework: Django >= 4.2

Documentation

The documentation is organized into the following sections:

Quick Start
Usage
LogiBoard Integration
Settings
Available Format Options
Required Email Settings

Quick Start

Getting started with django_logging is simple. Follow these steps to get up and running quickly:

Install the Package

first, Install django_logging via pip:

$ pip install dj-logging

Add to Installed Apps

Add django_logging to your INSTALLED_APPS in your Django settings file:

INSTALLED_APPS = [
    # ...
    'django_logging',
    # ...
]

Run Your Server

Start your Django Development server to verify the installation:

python manage.py runserver

when the server starts, you'll see an initialization message like this in your console:

INFO | 'datetime' | django_logging | Logging initialized with the following configurations:
Log File levels: ['DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL'].
Log files are being written to: logs.
Console output level: DEBUG.
Colorize console: True.
Log date format: %Y-%m-%d %H:%M:%S.
Email notifier enabled: False.

By default, django_logging will log each level to its own file:

DEBUG : logs/debug.log
INFO : logs/info.log
WARNING : logs/warning.log
ERROR : logs/error.log
CRITICAL : logs/critical.log

In addition, logs will be displayed in colorized mode in the console, making it easier to distinguish between different log levels.

That's it! django_logging is ready to use. For further customization, refer to the Settings section

Usage

Once django_logging is installed and added to your INSTALLED_APPS, you can start using it right away. The package provides several features to customize and enhance logging in your Django project. Below is a guide on how to use the various features provided by django_logging.

Basic Logging Usage:

At its core, django_logging is built on top of Python’s built-in logging module. This means you can use the standard logging module to log messages across your Django project. Here’s a basic example of logging usage:

import logging

logger = logging.getLogger(__name__)

logger.debug("This is a debug message")
logger.info("This is an info message")
logger.warning("This is a warning message")
logger.error("This is an error message")
logger.critical("This is a critical message")

These logs will be handled according to the configurations set up by django_logging, using either the default settings or any custom settings you've provided.

Context Manager:

You can use the config_setup context manager to temporarily apply django_logging configurations within a specific block of code. Example usage:

from django_logging.utils.context_manager import config_setup
import logging

logger = logging.getLogger(__name__)

def foo():
  logger.info("This log will use the configuration set in the context manager!")

with config_setup():
    """ Your logging configuration changes here"""
    foo()

# the logging configuration will restore to what it was before, in here outside of with block

Note: AUTO_INITIALIZATION_ENABLE must be set to False in the settings to use the context manager. If it is True, attempting to use the context manager will raise a ValueError with the message:

"You must set 'AUTO_INITIALIZATION_ENABLE' to False in DJANGO_LOGGING in your settings to use the context manager."

Log and Notify Utility:

To send specific logs as email, use the log_and_notify_admin function. Ensure that the ENABLE option in LOG_EMAIL_NOTIFIER is set to True in your settings:

from django_logging.utils.log_email_notifier.log_and_notify import log_and_notify_admin
import logging

logger = logging.getLogger(__name__)

log_and_notify_admin(logger, logging.INFO, "This is a log message")

You can also include additional request information (ip_address and browser_type) in the email by passing an extra dictionary:

from django_logging.utils.log_email_notifier.log_and_notify import log_and_notify_admin
import logging

logger = logging.getLogger(__name__)

def some_view(request):
    log_and_notify_admin(
        logger,
        logging.INFO,
        "This is a log message",
        extra={"request": request}
    )

Note: To use the email notifier, LOG_EMAIL_NOTIFIER["ENABLE"] must be set to True. If it is not enabled, calling log_and_notify_admin will raise a ValueError:

"Email notifier is disabled. Please set the 'ENABLE' option to True in the 'LOG_EMAIL_NOTIFIER' in DJANGO_LOGGING in your settings to activate email notifications."

Additionally, ensure that all Required Email Settings are configured in your Django settings file.

Execution Tracker Decorator:

The execution_tracker decorator is used to log the performance metrics of any function. It tracks execution time and the number of database queries for decorated function (if enabled).

Example Usage:

import logging
from django_logging.decorators import execution_tracker

@execution_tracker(logging_level=logging.INFO, log_queries=True, query_threshold=10, query_exceed_warning=False)
def some_function():
    # function code
    pass

Arguments:

logging_level (int): The logging level at which performance details will be logged. Defaults to logging.INFO.

log_queries (bool): Whether to log the number of database queries for decorated function(if DEBUG is True in your settings). If log_queries=True, the number of queries will be included in the logs. Defaults to False.

query_threshold (int): If provided, the number of database queries will be checked. If the number of queries exceeded the given threshold, a warning will be logged. Defaults to None.

query_exceed_warning (int): Whether to log a WARNING message if number of queries exceeded the threshold. Defaults to False.

Example Log Output:

INFO | 'datetime' | execution_tracking | Performance Metrics for Function: 'some_function'
  Module: some_module
  File: /path/to/file.py, Line: 123
  Execution Time: 0.21 second(s)
  Database Queries: 15 queries (exceeds threshold of 10)

If log_queries is set to True but DEBUG is False, a WARNING will be logged:

WARNING | 'datetime' | execution_tracking | DEBUG mode is disabled, so database queries are not tracked. To include number of queries, set `DEBUG` to `True` in your django settings.

Request Logging Middleware:

The django_logging.middleware.RequestLogMiddleware is a middleware that logs detailed information about each incoming request to the server. It is capable of handling both synchronous and asynchronous requests.

To enable this middleware, add it to your Django project's MIDDLEWARE setting:

MIDDLEWARE = [
   #...
   'django_logging.middleware.RequestLogMiddleware',
   #...
]

Key Features

Request Information Logging:

Logs the following details at the start of each request:
- Request method
- Request path
- Query parameters
- Referrer (if available)
Example log at request start:

INFO | 2024-10-03 16:29:47 | request_middleware | REQUEST STARTED:
method=GET
path=/admin/
query_params=None
referrer=http://127.0.0.1:8000/admin/login/?next=/admin/
| {'ip_address': '127.0.0.1', 'request_id': '09580021-6bff-4b82-99b5-c52406b2cc91',
   'user_agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36'}

Response Information Logging:

Logs the following details after the request is processed:
- User (or 'Anonymous' if not authenticated)
- HTTP Status code
- Content type
- Time taken to process the request
- Optionally logs SQL queries executed during the request (if enabled)
Example log at request completion:

INFO | 2024-10-03 16:29:47 | request_middleware | REQUEST FINISHED:
user=[mehrshad (ID:1)]
status_code=200
content_type=[text/html; charset=utf-8]
response_time=[0.08 second(s)]
3 SQL QUERIES EXECUTED
Query1={'Time': 0.000(s), 'Query':
          [SELECT "django_session"."session_key", "django_session"."session_data", "django_session"."expire_date" FROM "django_session"
          WHERE ("django_session"."expire_date" > '2024-10-03 12:59:47.812918' AND "django_session"."session_key" = 'uq0nrbglazfm4cy656w3451xydfirh45') LIMIT 21]}

Query2={'Time': 0.001(s), 'Query':
          [SELECT "auth_user"."id", "auth_user"."password", "auth_user"."last_login", "auth_user"."is_superuser", "auth_user".
          "username", "auth_user"."first_name", "auth_user"."last_name", "auth_user"."email", "auth_user"."is_staff", "auth_user".
          "is_active", "auth_user"."date_joined" FROM "auth_user" WHERE "auth_user"."id" = 1 LIMIT 21]}

| {'ip_address': '127.0.0.1', 'request_id': '09580021-6bff-4b82-99b5-c52406b2cc91',
  'user_agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36'}

Request ID:
- A unique request ID is generated for each request (or taken from the X-Request-ID header if provided). This request ID is included in logs and can help with tracing specific requests.
SQL Query Logging:
- If SQL query logging is enabled, all queries executed during the request will be logged along with their execution time.
Note: to enable Query logging, you can set LOG_SQL_QUERIES_ENABLE to True in settings. for more details, refer to the Settings.
Streaming Response Support:
- The middleware supports both synchronous and asynchronous streaming responses, logging the start and end of the streaming process, as well as any errors during streaming.
User Information:
- Logs the authenticated user's username and ID if available, or 'Anonymous' if the user is not authenticated.
IP Address and User-Agent:
- The middleware logs the client's IP address and user agent for each request.

Context Variables Usage

We use context variables in RequestLogMiddleware to store the following information for each request:

request_id: A unique identifier for the request.
ip_address: The client’s IP address.
user_agent: The client's user agent string.

These context variables can be accessed and used in other parts of the logging system or during the request processing lifecycle.

MonitorLogSizeMiddleware

This middleware monitors the size of the log directory and checks it weekly. It triggers the logs_size_audit management command to assess the total size of the log files. If the log directory size exceeds a certain limit (LOG_DIR_SIZE_LIMIT), the middleware sends a warning email to the ADMIN_EMAIL asynchronously.

To enable this middleware, add it to your Django project's MIDDLEWARE setting:

MIDDLEWARE = [
   #...
   'django_logging.middleware.MonitorLogSizeMiddleware',
   #...
]

Context Variable Management

django_logging includes a powerful ContextVarManager class, allowing you to manage context variables dynamically within your logging system. These variables are bound to the current context and automatically included in your log entries via the %(context)s placeholder in the log format.

Binding and Unbinding Context Variables

The ContextVarManager provides several methods to manage context variables efficiently:

bind(**kwargs):

The bind method allows you to bind key-value pairs as context variables that will be available during the current context. These variables can be used to add contextual information to log entries.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)

# Binding context variables
manager.bind(user="test_user", request_id="abc123")

logger.info("Logging with context")

Log Output:

INFO | 2024-10-03 12:00:00 | Logging with context | {'user': 'test_user', 'request_id': 'abc123'}

unbind(key: str):

The unbind method removes a specific context variable by its key. It effectively clears the context variable from the log entry.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)

manager.unbind("user")
logger.info("Logging without the 'user' context")

Log Output:

INFO | 2024-10-03 12:05:00 | Logging without the 'user' context | {'request_id': 'abc123'}

Batch Binding and Resetting Context Variables

batch_bind(**kwargs):

The batch_bind method binds multiple context variables at once and returns tokens that can be used later to reset the variables to their previous state. This is useful when you need to bind a group of variables temporarily.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)

tokens = manager.batch_bind(user="admin_user", session_id="xyz789")

logger.info("Logging with batch-bound context")

Log Output:

INFO | 2024-10-03 12:10:00 | Logging with batch-bound context | {'user': 'admin_user', 'session_id': 'xyz789'}

reset(tokens: Dict[str, contextvars.Token]):

The reset method allows you to reset context variables to their previous state using tokens returned by batch_bind.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)

manager.reset(tokens)

logger.info("Context variables have been reset")

Log Output:

INFO | 2024-10-03 12:15:00 | Context variables have been reset |

clear():

The clear method clears all bound context variables at once, effectively removing all contextual data from the log entry.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)
manager.clear()

logger.info("All context variables cleared")

Log Output:

INFO | 2024-10-03 12:20:00 | All context variables cleared |

Retrieving and Merging Context Variables

get_contextvars():

The get_contextvars method retrieves the current context variables available in the context. This method is useful for inspecting or debugging the context.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)

current_context = manager.get_contextvars()
print(current_context)  # Output: {'user': 'admin_user', 'session_id': 'xyz789'}

merge_contexts(bound_context: Dict[str, Any], local_context: Dict[str, Any]):

The merge_contexts method merges two dictionaries of context variables, giving priority to the bound_context. This is useful when you want to combine different sources of context data.

Example:

from django_logging.contextvar import manager

bound_context = {"user": "admin_user"}
local_context = {"request_id": "12345"}

merged_context = manager.merge_contexts(bound_context, local_context)
print(merged_context)  # Output: {'user': 'admin_user', 'request_id': '12345'}

get_merged_context(bound_logger_context: Dict[str, Any]):

The get_merged_context method combines the bound logger context with the current context variables, allowing you to retrieve a single dictionary with all the context data.

Example:

from django_logging.contextvar import manager

bound_logger_context = {"app_name": "my_django_app"}

merged_context = manager.get_merged_context(bound_logger_context)
print(merged_context)  # Output: {'app_name': 'my_django_app', 'user': 'admin_user'}

Scoped Context Management

scoped_context(**kwargs):

The scoped_context method provides a context manager to bind context variables temporarily for a specific block of code. After the block completes, the context variables are automatically unbound.

Example:

from django_logging.contextvar import manager
import logging

logger = logging.getLogger(__name__)

with manager.scoped_context(transaction_id="txn123"):
   logger.info("Scoped context active")

logger.info("Scoped context no longer active")

Log Output:

INFO | 2024-10-03 12:30:00 | Scoped context active | {'transaction_id': 'txn123'}
INFO | 2024-10-03 12:30:10 | Scoped context no longer active |

send_logs Command

This Django management command zips the log directory and emails it to a specified email address. The command is useful for retrieving logs remotely and securely, allowing administrators to receive log files via email.

Key Features:

Zips Log Directory: Automatically compresses the log directory into a single zip file.
Email Log Files: Sends the zipped log file to a specified email address.

How It Works:

Setup Log Directory: The command retrieves the log directory from Django settings (DJANGO_LOGGING['LOG_DIR']).
Zip the Logs: Compresses the entire log directory into a zip file stored in a temporary location.
Email the Zip File: Sends the zipped log file to the email address provided as an argument, attaching it to an email message.
Cleanup: After sending the email, the temporary zip file is deleted to free up disk space.

Command Execution:

To execute the command, use the following syntax:

python manage.py send_logs <email>

Example:

If you want to send the logs to [email protected], the command would be:

python manage.py send_logs [email protected]

This will zip the log directory and send it to [email protected] with the subject "Log Files".

generate_pretty_json Command

This Django management command allows you to locate and prettify JSON log files stored in a log directory that generated by django_logging. It takes JSON files from the log directory, formats them into a clean, readable structure, and saves the result in the pretty directory.

Key Features:

Locate JSON Logs: Automatically finds .json files in the json log directory.
Pretty Formatting: Reformats the JSON logs into a valid JSON array with proper indentation, improving readability.
Separate Output Directory: Saves the reformatted JSON files in a pretty subdirectory, preserving the original files.

How It Works:

Setup Directories: The command looks for a json subdirectory within your defined log directory. If it doesn't exist, an error is displayed.
Process JSON Files: Each .json file found in the directory is processed:
- Parses multiple JSON objects within the file.
- Reformats them as a pretty JSON array with proper indentation.
- Saves the new, formatted JSON in the pretty subdirectory with the prefix formatted_.

Command Execution:

To execute the command, use the following syntax:

python manage.py generate_pretty_json

Example:

Running the command will process the following files:

logs/json/error.json ➡ logs/json/pretty/formatted_error.json
logs/json/info.json ➡ logs/json/pretty/formatted_info.json

generate_pretty_xml Command

This Django management command allows you to locate and reformat XML log files stored in a log directory generated by django_logging. It processes XML files by wrapping their content in a <logs> element and saves the reformatted files in a separate directory.

Key Features:

Locate XML Logs: Automatically finds .xml files in the xml log directory.
Reformatting: Wraps XML content in a <logs> element, ensuring consistency in structure.
Separate Output Directory: Saves the reformatted XML files in a pretty subdirectory with the prefix formatted_, preserving the original files.

How It Works:

Setup Directories: The command looks for an xml subdirectory within your defined log directory. If it doesn't exist, an error is displayed.
Process XML Files: Each .xml file found in the directory is processed:
- The content of each XML file is wrapped inside a <logs> element.
- The reformatted file is saved in the pretty subdirectory with the prefix formatted_.

Command Execution:

To execute the command, use the following syntax:

python manage.py generate_pretty_xml

Example:

Running the command will process the following files:

logs/xml/error.xml ➡ logs/xml/pretty/formatted_error.xml
logs/xml/info.xml ➡ logs/xml/pretty/formatted_info.xml

logs_size_audit Command

This Django management command monitors the size of your log directory. If the total size exceeds the configured limit, the command sends a warning email notification to the admin. The size check helps maintain log storage and prevent overflow by ensuring administrators are informed when logs grow too large.

Key Features:

Log Directory Size Check: Automatically calculates the total size of the log directory.
Configurable Size Limit: Compares the total size of the log directory against a configured limit.
Email Notification: Sends an email warning to the administrator when the log size exceeds the defined limit.

How It Works:

Setup Log Directory: The command retrieves the log directory from Django settings, specifically DJANGO_LOGGING['LOG_DIR'] or the Default. If the directory doesn't exist, an error is logged and displayed.
Calculate Directory Size: It calculates the total size of the files in the log directory.
Compare with Size Limit: The command compares the total directory size (in MB) with the configured size limit, which can be configured as LOG_DIR_SIZE_LIMIT in settings.
Send Warning Email: If the directory size exceeds the configured limit, the command sends a warning email to the admin, detailing the current log size.

Command Execution:

To execute the command, use the following syntax:

python manage.py logs_size_audit

Example:

Running the command when the log directory exceeds the size limit will trigger an email to the administrator:

Example log size: 1200 MB (limit: 1024 MB)
An email will be sent to ADMIN_EMAIL configured in Django settings.

LogiBoard Integration

The LogiBoard in the django_logging package provides an interface for uploading, extracting, and exploring log files that have been zipped and shared via email. This allows for easier log management.

Note: Superuser Access Only

Only superusers have access to the LogiBoard URL. If accessed by a non-superuser, they will get Access Denied page made by Lazarus.

Setup Instructions

Add to URLs: Include the following in your URL configuration to enable access to LogiBoard:
```
from django.urls import path, include


urlpatterns = [
    # ...
    path('django-logging/', include('django_logging.urls')),
    # ...
]
```
LogiBoard will be accessible at the following link in your project after setting it up: /django-logging/log-iboard/
Static Files: Run the following command to collect and prepare the static files necessary for LogiBoard's interface:
```
python manage.py collectstatic
```
The collectstatic command is required to gather and serve static assets (such as JavaScript, CSS, and images) used by LogiBoard. This ensures the front-end of the log upload and browsing interface works correctly.
Enable LogiBoard: In your settings file, ensure the following setting is added under DJANGO_LOGGING:
```
DJANGO_LOGGING = {
    # ...
    "INCLUDE_LOG_iBOARD": True,
    # ...
}
```
This setting ensures that LogiBoard is available in your project.

Using LogiBoard

Logiboard is designed to help administrators easily review log files that have been zipped and sent via email (generated by the send_logs management command). This is particularly useful for remotely retrieving log files from production systems or shared environments.

Access Logiboard: Go to the link /django-logging/log-iboard/ in your project to open the LogiBoard interface.
Upload ZIP Files: Click the upload icon or drag and drop ZIP files into the upload area. Only ZIP files are supported for upload.
Explore Log Files: After uploading, Logiboard automatically extracts the log files and displays their structure. You can browse through directories and open log files in supported formats, such as .log, .txt, .json, and .xml.
Upload New Files: Once you're done reviewing, click the "Send Another" button to upload and explore more logs.

LogiBoard makes it simple to manage and review logs, ensuring you can quickly access and analyze critical log data.

The django_logging package provides predefined log format options that you can use in configuration. Below are the available format options:

FORMAT_OPTIONS = {
    1: "%(levelname)s | %(asctime)s | %(module)s | %(message)s | %(context)s",
    2: "%(levelname)s | %(asctime)s | %(context)s | %(message)s",
    3: "%(levelname)s | %(context)s | %(message)s",
    4: "%(context)s | %(asctime)s - %(name)s - %(levelname)s - %(message)s",
    5: "%(levelname)s | %(message)s | %(context)s | [in %(pathname)s:%(lineno)d]",
    6: "%(asctime)s | %(context)s | %(levelname)s | %(message)s",
    7: "%(levelname)s | %(asctime)s | %(context)s | in %(module)s: %(message)s",
    8: "%(levelname)s | %(context)s | %(message)s | [%(filename)s:%(lineno)d]",
    9: "[%(asctime)s] | %(levelname)s | %(context)s | in %(module)s: %(message)s",
    10: "%(asctime)s | %(processName)s | %(context)s | %(name)s | %(levelname)s | %(message)s",
    11: "%(asctime)s | %(context)s | %(threadName)s | %(name)s | %(levelname)s | %(message)s",
    12: "%(levelname)s | [%(asctime)s] | %(context)s | (%(filename)s:%(lineno)d) | %(message)s",
    13: "%(levelname)s | [%(asctime)s] | %(context)s | {%(name)s} | (%(filename)s:%(lineno)d): %(message)s",
    14: "[%(asctime)s] | %(levelname)s | %(context)s | %(name)s | %(module)s | %(message)s",
    15: "%(levelname)s | %(context)s | %(asctime)s | %(filename)s:%(lineno)d | %(message)s",
    16: "%(levelname)s | %(context)s | %(message)s | [%(asctime)s] | %(module)s",
    17: "%(levelname)s | %(context)s | [%(asctime)s] | %(process)d | %(message)s",
    18: "%(levelname)s | %(context)s | %(asctime)s | %(name)s | %(message)s",
    19: "%(levelname)s | %(asctime)s | %(context)s | %(module)s:%(lineno)d | %(message)s",
    20: "[%(asctime)s] | %(levelname)s | %(context)s | %(thread)d | %(message)s",
}

You can reference these formats by their corresponding integer keys in your logging configuration settings.

Required Email Settings

To use the email notifier, the following email settings must be configured in your settings.py:

EMAIL_HOST: The host to use for sending emails.
EMAIL_PORT: The port to use for the email server.
EMAIL_HOST_USER: The username to use for the email server.
EMAIL_HOST_PASSWORD: The password to use for the email server.
EMAIL_USE_TLS: Whether to use a TLS (secure) connection when talking to the email server.
DEFAULT_FROM_EMAIL: The default email address to use for sending emails.
ADMIN_EMAIL: The email address where log notifications will be sent. This is the recipient address used by the email notifier to deliver the logs.

Example Email Settings:

EMAIL_HOST = 'smtp.example.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'your-password'
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = '[email protected]'
ADMIN_EMAIL = '[email protected]'

These settings ensure that the email notifier is correctly configured to send log notifications to the specified ADMIN_EMAIL address.
