django-requestlog 1.1.8

Middleware to log http requests to postgresql

Django-Requestlog

Middleware who logs each request with their headers and the body into to PostgreSQL for diagnostic purposes.

Why Logging to the database?

Logging to the database instead of to a logfile has the advantage that it can be searched by people not having access to the server logs. Of course this only works for low traffic sites. And I recommend to purge those logs regularly with the provided manage command or celery task.

What is logged?

The log is written to the table requestlog_requestlog.

• timestamp
• client IP address
• django user-id
• method
• URL
• header fields
• cookies
• query parameter
• POST body
• HTTP status code
• the first 1024 of the response

Settings

Request logging has to be explicitely enabled (for performance reasons):

REQUEST_LOGGING_ENABLED = True

You can ask the service to ignore certain fields from the querystring and the header. You do this by setting the name of the fields in the Django settings variable REQUEST_LOGGING_HIDE_PARAMETERS. For example like this:

REQUEST_LOGGING_HIDE_PARAMETERS = [ 'HTTP_AUTHORIZATION', 'password' ]

Filter certain IPs (e.g. internal Kubernetes health check requests)

REQUEST_LOGGING_IGNORE_IPS = [ '10.2.3.4' ]

Filter certain paths by Regex (including query string):

REQUEST_LOGGING_IGNORE_PATHS = [ '/admin/login' ]

Purge old entries

You can use the following management command which deletes entries older than 3 days:

./manage.py requestlog_purge

Or you trigger the task with Celery beat by adding a shared task to your projects task list:

In your settings:

CELERY_BEAT_SCHEDULE = {
    ...    
    'requestlog.tasks.delete_old_requestlog_entries': {
        'task': 'requestlog.tasks.delete_old_requestlog_entries',
        'schedule': crontab(hour=2, minute=0)
        'args': (30,) # This is the number of days to keep the entries 
    },
}
