Standard Library Logging

Logfire can act as a sink for standard library logging by emitting a Logfire log for every standard library log record.

main.py

from logging import basicConfig, getLogger

import logfire

logfire.configure()
basicConfig(handlers=[logfire.LogfireLoggingHandler()])

logger = getLogger(__name__)

logger.error("Hello %s!", "Fred")
# 10:05:06.855 Hello Fred!

Oh no! Too many logs from...

A common issue with logging is that it can be too verbose... Right?

Don't worry! We are here to help you.

In those cases, you can set the log level to a higher value to suppress logs that are less important. Let's see an example with the apscheduler logger:

main.py

import logging

logger = logging.getLogger("apscheduler")
logger.setLevel(logging.WARNING)

In this example, we set the log level of the apscheduler logger to WARNING, which means that only logs with a level of WARNING or higher will be emitted.
