Is it possible to container restarts for a CONTAINER_GROUP_INSTANCE?

crabbylou — Fri, 03 Nov 2023 16:56:47 GMT

I can grab a bunch of container statistics for CONTAINER_GROUP_INSTANCES easily, but I am trying to get container restarts for a container group instance in a given namespace.

Is there any way to do this? Am I mixing apples and oranges here?

Any advice appreciated.

Do you want to perform a reboot or display information about restarts on your environments?

Display the number of restarts per time interval.

There is a metric to report the number of container restarts: builtin:kubernetes.container.restarts

Hi Radek, I cannot get this to pull for a CONTAINER_GROUP_INSTANCE. Is there a trick to this?

I can pull for a Kubernetes Namespace.

All my other CGI stats are being queried by CGI.

Hi,

For the builtin:kubernetes.container.restarts metric, you do not have the CONTAINER_GROUP_INSTANCE dimension available. This is a different entityType. It is only present for metrics:

builtin:containers.cpu.*
builtin:containers.memory.*

The metric that tells us about pod restarts on Kubernetes is builtin:kubernetes.container.restarts and below you have the dimensions you can use:

Kubernetes workload (dt.entity.cloud_application), Kubernetes pod (dt.entity.cloud_application_instance), Kubernetes namespace (dt.entity.cloud_application_namespace), Kubernetes cluster (dt.entity.kubernetes_cluster), Kubernetes node (dt. entity.kubernetes_node), dt.kubernetes.node.system_uuid, k8s.cluster.name, k8s.container.name, k8s.cronjob.name, k8s.deployment.name, k8s.namespace.name, k8s.node.name, k8s.pod.name, k8s.pod.uid, k8s.workload.kind, k8s.workload.name.

In this case, I would recommend using Kubernetes namespace.

Some docs for you:

Hope this help.
