Chapter 3. Using the OpenShift Container Platform dashboard to get cluster information

The OpenShift Container Platform web console captures high-level information about the cluster.

3.1. About the OpenShift Container Platform dashboards page

Access the OpenShift Container Platform dashboard, which captures high-level information about the cluster, by navigating to HomeOverview from the OpenShift Container Platform web console.

The OpenShift Container Platform dashboard provides various cluster information, captured in individual dashboard cards.

The OpenShift Container Platform dashboard consists of the following cards:

  • Details provides a brief overview of informational cluster details.

    Status include ok, error, warning, in progress, and unknown. Resources can add custom status names.

    • Cluster ID
    • Provider
    • Version
  • Cluster Inventory details number of resources and associated statuses. It is helpful when intervention is required to resolve problems, including information about:

    • Number of nodes
    • Number of pods
    • Persistent storage volume claims
    • Bare metal hosts in the cluster, listed according to their state (only available in metal3 environment)
  • Status helps administrators understand how cluster resources are consumed. Click on a resource to jump to a detailed page listing pods and nodes that consume the largest amount of the specified cluster resource (CPU, memory, or storage).
  • Cluster Utilization shows the capacity of various resources over a specified period of time, to help administrators understand the scale and frequency of high resource consumption, including information about:

    • CPU time
    • Memory allocation
    • Storage consumed
    • Network resources consumed
    • Pod count
  • Activity lists messages related to recent activity in the cluster, such as pod creation or virtual machine migration to another host.

3.2. Recognizing resource and project limits and quotas

You can view a graphical representation of available resources in the Topology view of the web console Developer perspective.

If a resource has a message about resource limitations or quotas being reached, a yellow border appears around the resource name. Click the resource to open a side panel to see the message. If the Topology view has been zoomed out, a yellow dot indicates that a message is available.

If you are using List View from the View Shortcuts menu, resources appear as a list. The Alerts column indicates if a message is available.
