Grafana

Here's some really cool Grafana dashboards that display our Graphite metrics:

Graphite

Raw metrics can be browsed at https://graphite.wikimedia.org/ (under Metrics -> eventlogging).

We publish 4 types of counts to graphite:

  • Overall counts
  • Per schema counts
  • Server side counts
  • Client side counts

Within the overall counts, there are 4 submetrics:

  • Raw counts: Number of all events that reach the system.
  • Valid counts: Number of events that pass validation.
  • insertAttempted: Number of events that get queued up for insertion to MySQL database.
  • inserted: Number of events that get actually inserted into MySQL database.
