Removing a Cluster

1. Uninstall the Helm chart

helm uninstall dataagent --namespace dataagent

This removes the agent pod, service account, ClusterRole, and ClusterRoleBinding.

The mTLS credential secret (dataagent-mtls-credentials) is created at runtime by the agent, not by Helm, so it survives helm uninstall. Delete it explicitly to avoid a reinstall reusing the stale certificate:

kubectl delete secret dataagent-mtls-credentials --namespace dataagent --ignore-not-found

2. Delete the namespace (optional)

The dataagent namespace is always preserved on helm uninstall, regardless of who created it. To remove it:

kubectl delete namespace dataagent

3. Remove the cluster from the dashboard

After uninstalling the agent, the cluster will appear as Disconnected in the dashboard. To remove it entirely:

1. Go to Settings → Clusters
2. Find the disconnected cluster
3. Click Remove

Effect on incidents

• Active incidents from the removed cluster are automatically resolved when the agent disconnects and stops sending heartbeats (within 4 hours via auto-resolution).
• Removing the cluster from the dashboard immediately deletes all its incident history.
