Datadog Agent

Kube_cluster_name label does not show in Kfuse stack

Symptom

MELT data ingested from Datadog agent is missing the kube_cluster_name label.

Resolution

There is a known issue in Datadog agent cluster name detection that requires the cluster agent to be up. If the agent starts up before the cluster agent, then it fails to detect the cluster name. See https://github.com/DataDog/datadog-agent/issues/24406 .

A workaround is to do a rollout restart of the Datadog agent daemonset.

kubectl rollout restart daemonset datadog-agent
