Previous to version 4, the documentation for Openshift referenced Heapster for obtaining metrics on resource usage of pods, such as in this documentation:


In researching Heapster, I see that it may have been deprecated:


I do see that references to it have been somewhat removed from later documentation, such as this:


Has Heapster been replaced with something that is still maintained? Or has Red Hat taken to ensuring its properly supported (secure, functional) for version 4 and beyond?


Hi Ryan, Heapster/Hawkular has been replaced by Prometheus/Grafana and the Cluster Monitoring Operator (https://docs.openshift.com/container-platform/4.1/monitoring/cluster-monitoring/about-cluster-monitoring.html)

This will also be used for Pos Autoscaling aka HPA https://docs.openshift.com/container-platform/4.1/nodes/pods/nodes-pods-autoscaling.html

So no more heapster for OCP 4.x
