Currently, EventGate is using service-runner ^2.7.7, emitting metrics via statsd, which in production eventgate-wikimedia is translated to prometheus via promtheus-statsd-exporter. We should do the following:
- Update to a recent service-runner (^2.8.1) with Prometheus metrics support.
- Configure eventgate-wikimedia to use Prometheus metrics.
- Remove prometheus-statsd-exporter usaeg from eventgate helm chart.
- Make sure Grafana dashboards continue to work, or make new ones if metrics have changed.
This will allow us to do T257237: eventgate-wikimedia should emit metrics about validation errors
