Question

How can you stop New Relic / Celery from constantly printing the below to Heroku’s log.

app[scheduler.1]: [INFO/MainProcess] Starting new HTTP connection (1): collector-6.newrelic.com
app[scheduler.1]: [INFO/MainProcess] Starting new HTTP connection (1): collector-6.newrelic.com
app[scheduler.1]: [INFO/MainProcess] Starting new HTTP connection (1): collector-6.newrelic.com
app[scheduler.1]: [INFO/MainProcess] Starting new HTTP connection (1): collector-6.newrelic.com

Setup

The above log entries appear every minute. The app reporting this is a celery worker started via Procfile that reads (in part):

scheduler: newrelic-admin run-program python manage.py celery worker --loglevel=ERROR -B -E --maxtasksperchild=1000

Despite setting loglevel to ERROR it appears that celery is ignoring this argument. Interestingly enough, on my local machine, this setting is respected.

Versions

celery==3.0.12
django-celery==3.0.11
newrelic==1.6.0.13

    Temporary solution, per New Relic support, is to add the below to your settings.py or a celeryconfig.py (depending on which you use for celery settings).

    import logging
class RequestsConnectionFilter(logging.Filter):
    def filter(self, record):
        return False
logging.getLogger('newrelic.lib.requests.packages.urllib3.connectionpool').addFilter(RequestsConnectionFilter())

    NR support told me they plan to build this suppression into future versions of the python agent.
