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.
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.
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:
Log in to the Grafana web UI as described in Access StackLight web UIs.
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:
Provides the overall health status of the Ceph cluster, capacity, latency, and recovery metrics.
Provides an overview of the host-related metrics, such as the number of Ceph Monitors, Ceph OSD hosts, average usage of resources across the cluster, network and hosts load.
Provides metrics for Ceph OSDs, including the Ceph OSD read and write latencies, distribution of PGs per Ceph OSD, Ceph OSDs and physical device performance.
Provides metrics for Ceph pools, including the client IOPS and throughput by pool and pools capacity usage.
Ironic bare metal
Provides graphs on Ironic health, HTTP API availability, provisioned nodes by state and installed
