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.

On Grafana's Home Dashboard, click the Home dropdown menu to access the following sample dashboards:
CLDB Dashboard
The CLDB dashboard provides a high-level view of the MapR 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, MapR Filesystem I/O, MapR 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 and the VolumeName drop-down menu on the top left can be used to switch between volumes.

Once you select a dashboard, it displays in the recently viewed dashboards list on the Home Dashboard.

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 in the MCS. 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 in the MCS 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: The manual configuration must be applied each time you view a dashboard.
