Make the most out of the logging system

Procrastinate logs quite a few things, using structured logging. By default, the messages can seem not very informative, but the details are not mixed into the log messages, they are added as extra elements to the logs themselves.

This way, you can adapt the logs to whatever format suits your needs the most, using a log filter:

import logging

class ProcrastinateLogFilter(logging.Filter):
    def filter(record):
        # adapt your record here
        return True

logging.getLogger("procrastinate").addFilter(ProcrastinateLogFilter)

We’ll try to document what attribute is available on each log, but one common thing is the “action” attribute, that describes the event that triggered the logging. You can match on this.
