OpenCensus logging Integration

|pypi|

.. |pypi| image:: https://badge.fury.io/py/opencensus-ext-logging.svg :target: https://pypi.org/project/opencensus-ext-logging/

The logging integration enriches the log records with trace ID, span ID and sampling flag. The following attributes will be added to LogRecord:

* traceId
* spanId
* traceSampled

Note that this only takes effect for loggers created after the integration.

Installation

::

pip install opencensus-ext-logging

Usage

.. code:: python

import logging

from opencensus.trace import config_integration
from opencensus.trace.samplers import AlwaysOnSampler
from opencensus.trace.tracer import Tracer

config_integration.trace_integrations(['logging'])
logging.basicConfig(format='%(asctime)s traceId=%(traceId)s spanId=%(spanId)s %(message)s')
tracer = Tracer(sampler=AlwaysOnSampler())

logger = logging.getLogger(__name__)
logger.warning('Before the span')
with tracer.span(name='hello'):
    logger.warning('In the span')
logger.warning('After the span')
