Sample Dashboards in Grafana
Use the sample dashboards to get familiar with the types of graphs you can create. As of EEP 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:
- Navigate to the Welcome to Grafana page.
- On the left-side icon menu, click Dashboard > Manage. The list of dashboards is displayed.
- Click a dashboard in the list to load the dashboard. The General / Node Dashboard page is displayed.
- 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, file system 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 EEPs, 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 toNone
, 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 toNone
, 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 toNone
, 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 entermapr.cluster.root
in theVolumeName
drop-down menu.
NOTE
You must apply the manual configuration each time you view a dashboard.
