Metric Used

kube_pod_container_resource_limits

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 memory utilization falls below the critical threshold.

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