loki-handler

Python logging handler for Loki.
https://grafana.com/loki

Backport of Andrey Maslov's python-logging-loki for Python 2.X.

Installation

pip install loki-handler

Usage

import logging
import loki_handler


handler = loki_handler.LokiHandler(
    url="https://my-loki-instance/loki/api/v1/push", 
    tags={"application": "my-app"},
    auth=("username", "password"),
    version="1",
)

logger = logging.getLogger("my-logger")
logger.addHandler(handler)
logger.error(
    "Something happened", 
    extra={"tags": {"service": "my-service"}},
)

Example above will send Something happened message along with these labels:

• Default labels from handler
• Message level as serverity
• Logger's name as logger
• Labels from tags item of extra dict

The given example is blocking (i.e. each call will wait for the message to be sent).
