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 OpenSearch Dashboards link to immediately view relevant logs in the OpenSearch Dashboards web UI. The OpenSearch Dashboards web UI displays logs filtered using the Grafana dashboard variables, such as the drop-downs. Once you amend the variables, wait for Grafana to generate a new URL.

Note

Due to the known issue, the View logs in OpenSearch Dashboards link does not work in Container Cloud 2.26.0 (Cluster releases 17.1.0 and 16.1.0). The issue is addressed in Container Cloud 2.26.1 (Cluster releases 17.1.1 and 16.1.1).

Caution

The Grafana dashboards that contain drop-down lists are limited to 1000 lines. Therefore, if you require data on a specific item, use the filter by name instead.

Note

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 Getting access.

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

   Component	Dashboard	Description
   Ceph cluster	Ceph Cluster	Provides the overall health status of the Ceph cluster, capacity, latency, and recovery metrics.
