Metrics and charts for read distribution
Problem to solve
When using horizontal read distribution &2013 (closed) in a Gitaly Cluster, I want to be able visualize the request rates per Gital node so that I can observe read distribution in action.
Proposal
Add a chart to the default Grafana dashboard that shows the rate RPC rate for each Gitaly node.
This way I can see if the load is being distributed as expected each Gitaly node.
