Missing nodes

Problem

You have completed the installation procedure for New Relic's Kubernetes integration and the cluster shows up in your New Relic account, but some or all nodes are missing.

Solution

If you deployed the infrastructure agent and completed the Kubernetes installation procedure but not all nodes show up, complete these steps:

1. Confirm that the infrastructure agent can be scheduled on every node by running:

   kubectl describe daemonset RELEASE_NAME-nrk8s-kubelet

   Copy

   Notice that in V2 version of the Kubernetes integration you needed to run:

   kubectl describe daemonset newrelic-infra

   Copy

2. Confirm that the time on all nodes is accurate. Nodes that are more than 2 minutes ahead or behind will not show up in the Cluster explorer. The following NRQL query can be used to check if this is the case:

   FROM K8sNodeSample SELECT latest(nr.ingestTimeMs - timestamp) / 1000 AS 'Clock offset seconds' FACET nodeName LIMIT max SINCE 1 DAY AGO

   Copy

3. Retrieve the logs from the infrastructure agent on the nodes that do not appear in the cluster explorer and confirm there are no error messages.
