Description

Proposal

Provide a metric for metric server performance:

  • The rate and error rate to update HPA
  • The rate to query the so active

See https://github.com/kedacore/keda/issues/3098#issuecomment-1144421310

Use-Case

Monitor integration between HPA & metric server

Anything else?

Relates to https://github.com/kedacore/keda/issues/3098

Contributor guide

Research direction
Explore the existing metrics system in KEDA (e.g., Prometheus metrics endpoint) and implement new metrics for metric server performance: rate and error rate of HPA updates, and query rate.
