Kubernetes Management Pack Alerts are not triggering

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

You configured custom alerts for Kubernetes nodes to trigger based on CPU Usage %. However, such metric does not existed, and the alerts are not being triggered. 

Environment

Aria Operations 8.x

Resolution

The metrics for CPU/Memory/Disk Usage % are defined for cAdvisor as the 'Collector Service'.  Whereas the 'Collector Service' for Prometheus currently only comes with OOTB metrics that are defined at cluster level for CPU, memory, and disk usage. Recommend creating custom alerts on Kubernetes node objects with the Prometheus OOTB metrics, such as the Usage (%) metric that can be found under the "Throttle and Usage(CPU)" metric folder.
