Overview

Today we have hypershift_hostedcluster_nodepools as a metric exposed to provide information on the # of nodepools used per cluster. 

Additional NodePools metrics such as hypershift_nodepools_size and hypershift_nodepools_available_replicas are available but not ingested in Telemetry.

In addition to knowing how many nodepools per hosted cluster, we would like to expose the knowledge of the nodepool size.

This will help inform our decision making and provide some insights on how the product is being adopted/used.

Goals

The main goal of this epic is to show the following NodePools metrics on Telemeter, ideally as recording rules: 

• Hypershift_nodepools_size

• hypershift_nodepools_available_replicas

Requirements

The implementation involves creating updates to the following GitHub repositories:

• Cluster Monitoring Operator
• HyperShift Operator (like this PR)
