Sample Dashboards in Grafana

Use the sample dashboards to get familiar with the types of graphs you can create. As of MEP 1.1, sample dashboards are available by default in Grafana.

Displaying the Sample Dashboards

For Grafana 4.x, 5.x, and 6.x, navigate to the Welcome to Grafana page, and click the Home drop-down menu to display the sample dashboards. Once you select a dashboard, it displays in the Recently viewed dashboards list on the Home page.

In Grafana 7.5.x and later, use these steps to display the dashboards:
  1. Navigate to the Welcome to Grafana page.
  2. On the left-side icon menu, click Dashboard > Manage. The list of dashboards is displayed.
  3. Click a dashboard in the list to load the dashboard. The General / Node Dashboard page is displayed.
  4. Loading the dashboard adds the dashboard to the Recently viewed dashboards list on the General / Home page.

Sample Dashboard Descriptions

CLDB Dashboard
The CLDB dashboard provides a high-level view of the data-fabric cluster. It displays the following information about the cluster: number of nodes, status of nodes, number of volumes, container information, disk capacity, and the utilization of CPU, memory, and disks across the cluster.
Node Dashboard
The Node dashboard provides node-specific information. It displays the following information for the selected node: CPU, memory, network I/O, filesystem I/O, HPE Ezmeral Data Fabric Database operations, and Node Manager metrics. All the metrics are tagged with node hostname and the fqdn drop-down menu on the top left can be used to switch between nodes.
Volume Dashboard
The Volume dashboard provides volume-specific information. It displays the following information for the selected volume: raw data size, snapshot size, total size (including the snapshot size), volume utilization trends, read/write latency, number of reads/writes, and read/write throughput. All the metrics are tagged with volume name. Use the VolumeName drop-down menu on the top left to switch between volumes.

Troubleshooting Sample Dashboards

The sample dashboards should display metrics automatically. However, with certain MEPs, some manual configuration may be required to view sample dashboard metrics.

Configure the ClusterID in the CLDB dashboard
When the ClusterID drop-down menu on the CLDB dashboard is set to None, you must manually enter the ClusterID. You can determine the ClusterID from the Manage Licenses page on the Control System. ClusterID is usually an eighteen digit number.
Configure the Hostname in the Node dashboards
When the fqdn drop-down menu on the Node dashboard is set to None, you must manually enter the hostname for the node that you want to view metrics for.
Configure the Volume in the Volume dashboard
When the VolumeName drop-down menu on the Volume dashboard is set to None, you must manually enter the volume name for the volume that you want to view metrics for. The Volumes page on the Control System lists the volume names in the format required by the field. For example, you can enter mapr.cluster.root in the VolumeName drop-down menu.
Note: You must apply the manual configuration each time you view a dashboard.
