Kubernetes agents fails to collect Performance metrics due to not able to unable to access heapster name space. Below error is logged in agent log:
In the current version of Container Management cartridge, Kubernetes agent relies on Heapster service for performance metrics collection. If Heapster service information in agent properties is missing/incorrect or the service itself is encountering any issues in the target/monitored Kubernetes cluster then the agent will not be able to access the service name space.
Verify that Heapster service Name Space and Heapster Service Name parameters are configured correctly in agent properties
Restart Heapster service to check if resolves the issue
If issue still persists, please gather Agent Manager DEBUG bundle for further investigation
