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.
pip install opencensus-ext-logging
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')
