View Grafana dashboards

Using the Grafana web UI, you can view the visual representation of the metric graphs based on the time series databases. Most Grafana dashboards include a View logs in Kibana link to immediately view relevant logs in the Kibana web UI.

Note

Starting from Container Cloud 2.12.0, 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 Access StackLight web UIs.

  2. From the drop-down list, select the required dashboard to inspect the status and statistics of the corresponding service in your management or managed cluster:
