Metric Used

container_cpu_usage_seconds_total

Note : This is a Kubernetes metric used for instance availability monitoring. If the metric is not available, use the similar metric as exposed by the monitoring system.

Resolution The alert gets cleared when the CPU utilization is below the critical threshold.

Note: The threshold is configurable in the SeppAlertrules.yaml file.
