Change Details

* [] Cache hit rates and size for: * [] ParserCache (latest revision) * [] ParserCache (stable revision) -- this currently isn't split out in the existing Grafana board * [] RevisionOutputCache (older revisions) * [] Parser load * [] Kartotherian load * [x] Logs: duplicate parses coming from Kartographer * https://logstash.wikimedia.org/goto/2b8afe93427118362ea5c4f2ac1b7323 * [] Logs: stable cache miss Healthy: no impact on load Unhealthy: decrease in RevisionOutputCache cache hit rate; increase in parser load; any stable cache miss We'll want to watch the stable cache long-term.

* [] Cache hit rates and size for: * [] ParserCache (latest revision) * [] ParserCache (stable revision) -- this currently isn't split out in the existing Grafana board, and might be impossible because it's using the same store as the latest ParserCache. Maybe we add logging for cache hit / miss, or not split out for now since we don't expect any impact. * [] RevisionOutputCache (older revisions) * [] Parser load * [] Kartotherian load * [x] Logs: duplicate parses coming from Kartographer * https://logstash.wikimedia.org/goto/2b8afe93427118362ea5c4f2ac1b7323 * [] Logs: stable cache miss Healthy: no impact on load Unhealthy: decrease in RevisionOutputCache cache hit rate; increase in parser load; any stable cache miss We'll want to watch the stable cache long-term.
