As a recommendation from performance review (T246707), we should track the rate at which relevant Echo events/notifications are occurring.
This was originally instrumented with event logging (see Schema:Echo), but that was disabled because it was seen as redundant with data already in Echo's DB tables: https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/274345
Q: Do we have a good way of using the rate of inserts on a given DB table as a metric? A: It appears not.

[mediawiki/extensions/Echo@master] Collect baseline event and notification stats
@Mholloway where can we see these new stats?
Edit: I gave it a try and found the metrics in the Graphite data source. I created a draft grafana dashboard to take a first look at it https://grafana.wikimedia.org/d/onyD7cOMk/echo-extension-notification-baseline-track?orgId=1
Thanks for picking that up, @MSantos. I guess we can close this ticket out now that we know the metrics are indeed being collected (and we have a dashboard for them).
