Cluster health monitoring

You can monitor the status of your clusters, use Red Hat Lightspeed advisor to manage your cluster health, troubleshoot a stale cluster, and create integrations with third-party applications to receive cluster event notifications.

Cluster status reference

With the Red Hat OpenShift Cluster Manager, you can manage your clusters and monitor them for potential issues. The Status column in the Clusters list reports each cluster’s state so you can monitor your clusters at a glance.

The cluster status is shown in the Clusters list in OpenShift Cluster Manager. Normally, a cluster shows a status of Ready, however, there are other possible cluster statuses.

Table 1. Cluster status
Cluster status Description

Waiting

STS clusters only. Waiting for users to complete the necessary tasks before the cluster can be installed.

Validating

CCS clusters only. Waiting for users to complete the necessary tasks before the cluster can be installed.

Pending

Interim state after users complete the required tasks but before the cluster installation starts.

Installing

The cluster is currently being installed.

Ready

Cluster is installed and is ready for use.

Cluster is connected to Red Hat OpenShift Cluster Manager and is reporting Telemetry data. No manual registration is required.

Error

Failure in creating or destroying a cluster.

Disconnected

Cluster does not send Telemetry data to OpenShift Cluster Manager. The disconnection could be because the cluster is installed on a private network, or because the Telemetry is disabled.

Stale

The cluster is connected but has not sent Telemetry data to OpenShift Cluster Manager recently.

You can no longer view internal information about the cluster in the OpenShift Cluster Manager Monitoring tab, including any alerts firing, cluster operators, and resource usage. To know the workaround steps, see Troubleshooting a stale cluster.

Limited support

When a cluster transitions to a Limited Support status, it means that the SLA is no longer applicable and credits requested against the SLA are denied. It does not mean that you no longer have product support. The cluster can return to a fully-supported status if the violating factors are remediated.

Powering down

Cluster goes into hibernation mode.

Hibernating

Cluster is inactive. Users can choose to move clusters into hibernation to reduce maintenance costs.

Resuming

Interim state after users choose to take clusters from hibernation mode. Cluster is powering on but not fully functional yet.

Uninstalling

Cluster is being uninstalled.

Archived

Clusters are moved from the cluster list view to the Archive list. In the archived list, you can see two tabs only: Overview and Support.
