+title: Registered clusters
+weight: 105
+---
+
+The commands/steps listed on this page can be used to check clusters that you are registering or that are registered in Rancher.
+
+Make sure you configured the correct kubeconfig (for example, `export KUBECONFIG=$PWD/kubeconfig_from_imported_cluster.yml`)
+
+### Rancher agents
+
+Communication to the cluster (Kubernetes API via cattle-cluster-agent) and communication to the nodes is done through Rancher agents.
+
+If the cattle-cluster-agent cannot connect to the configured `server-url`, the cluster will remain in **Pending** state, showing `Waiting for full cluster configuration`. 
+
+#### cattle-node-agent
+
+> Note: cattle-node-agents are only present in clusters created in Rancher with RKE.
+
+Check if the cattle-node-agent pods are present on each node, have status **Running** and don't have a high count of Restarts:
+
+```
+kubectl -n cattle-system get pods -l app=cattle-agent -o wide
+```
+
+Example output:
+
+```
+NAME                      READY     STATUS    RESTARTS   AGE       IP                NODE
+cattle-node-agent-4gc2p   1/1       Running   0          2h        x.x.x.x           worker-1
+cattle-node-agent-8cxkk   1/1       Running   0          2h        x.x.x.x           etcd-1
+cattle-node-agent-kzrlg   1/1       Running   0          2h        x.x.x.x           etcd-0
+cattle-node-agent-nclz9   1/1       Running   0          2h        x.x.x.x           controlplane-0
+cattle-node-agent-pwxp7   1/1       Running   0          2h        x.x.x.x           worker-0
+cattle-node-agent-t5484   1/1       Running   0          2h        x.x.x.x           controlplane-1
+cattle-node-agent-t8mtz   1/1       Running   0          2h        x.x.x.x           etcd-2
+```
+
+Check logging of a specific cattle-node-agent pod or all cattle-node-agent pods:
+
+```
+kubectl -n cattle-system logs -l app=cattle-agent
+```
+
+#### cattle-cluster-agent
+
+Check if the cattle-cluster-agent pod is present in the cluster, has status **Running** and doesn't have a high count of Restarts:
+
+```
+kubectl -n cattle-system get pods -l app=cattle-cluster-agent -o wide
+```
+
+Example output:
+
+```
+NAME                                    READY     STATUS    RESTARTS   AGE       IP           NODE
+cattle-cluster-agent-54d7c6c54d-ht9h4   1/1       Running   0          2h        x.x.x.x      worker-1
+```
+
+Check logging of cattle-cluster-agent pod:
+
+```
+kubectl -n cattle-system logs -l app=cattle-cluster-agent
+```
