Export hosted sentry statsd metrics to prometheus

Primary LanguagePython

Monitor hosted sentry with prometheus

Since sentry does not support prometheus as a monitoring backend, we can send StatsdMetricsBackend metrics to statsd_exporter and configure prometheus to scrape them.

Demo:

sentry metrics

TODO

  • Add grafana dashboard
  • Deploy to kubernetes/minikube

Test

docker-compose build
docker-compose up

  • to view the scraped metrics in prometheus navigate to http://localhost:9090/

  • to view the translated statsd metrics navigate to http://localhost:9102/metrics

Notes:

  • The first time you do docker-compose up, you need to run:

    • docker exec -it <sentry_web_container_id> bash

    • sentry upgrade (we need to create database tables, and create a superuser account).

    • docker-compose stop

    • docker-compose up

  • The statsd metrics backend is configured in sentry.conf.py. Ref: (https://github.com/getsentry/sentry/blob/master/docs/internal-metrics.rst)
