How to use loguru with google.cloud.logging

[fabianmax]

Hi,

I enjoy using loguru due to its simplicity. Unfortunately, I am currently running into the problem of how to combine loguru with the google.cloud.logging function to have correct logging in GCP Cloud Functions.

The described way is this: https://cloud.google.com/logging/docs/reference/libraries

Any ideas how to combine loguru with this?

Hi.

This is surely possible, but I'm unable to install google-cloud-logging to test my hypothesis.

You can for example use a custom function propagating logs to GCP as a Loguru sink:

from google.cloud import logging
from loguru import logger

logging_client = logging.Client()
gcp_logger = logging_client.logger("gcp-logger")

def log_to_gcp(message):
    gcp_logger.log_text(message, severity=message.record["level"].name)

logger.add(log_to_gcp)

According to documentation, you can also maybe call client.setup_logging() that will configure a standard handler compatible with standard logging. You can retrieve it and add it as a Loguru sink, as Loguru supports standard handlers as well.

Here's a trick i found, which work https://stackoverflow.com/a/77275130/7052018

_GCP_LOG_FORMAT = (
        "{level:<.1}{time:MMDD HH:mm:ss.SSSSSS} {process} {name}:{line}] {message} | {extra}"
    )

    logger.remove()
    logger.add(
        sys.stdout,
        format=_GCP_LOG_FORMAT,
        level=log_level,
        colorize=True,
    )
