View Grafana dashboards

Using the Grafana web UI, you can view the visual representation of the metric graphs based on the time series databases.

This section describes only the OpenStack-related Grafana dashboards. For other dashboards, including the system, Kubernetes, Ceph, and StackLight dashboards, see Mirantis Container Cloud Operations Guide: View Grafana dashboards.

Note

• Some Grafana dashboards include a View logs in OpenSearch Dashboards link to immediately view relevant logs in the OpenSearch Dashboards web UI.

• Grafana dashboards that present node data have an additional Node identifier drop-down menu. By default, it is set to machine to display short names for Kubernetes nodes. To display Kubernetes node name labels, change this option to node.

To view the Grafana dashboards:

1. Log in to the Grafana web UI as described in Mirantis Container Cloud Operations Guide: Access StackLight web UIs.

2. From the drop-down list, select the required dashboard to inspect the status and statistics of the corresponding service deployed in Mirantis OpenStack on Kubernetes:
