Editing Gitaly dashboards

Use the Grafana web interface to make changes to dashboards if necessary.

Remember to hit the 'Save' button at the top of the Grafana screen when making changes.

Tiled (repeated) dashboards

If you want to make a change across a tiled Grafana dashboard such as the feature request rate overview, then edit the first tile (top left). Its settings get applied to the other tiles as well. If you edit any tile other than the first your changes will be lost.

Drop-down values

At the top of most of our Grafana dashboards you will find drop-down menus for GRPC method names, Prometheus jobs etc. The possible values in these drop-downs are defined with Prometheus queries. To see or change these queries, go into the dashboard's global settings (the gear icon at the top of the page) and look in the 'Templating' section. You can then edit entries.

Note that Grafana 'templates' use a combination of PromQL and Grafana-specific modifiers.

Ad-hoc latency graphs with ELK

Gitaly RPC latency data from Prometheus uses irregular (exponential) bucket sizes which gives you unrealistic numbers. To get more realistic percentiles you can use ELK.

  • Go to ELK
  • Click 'Visualize'
  • Search for gitaly rpc latency example
  • Edit as needed
