Viewing the list of Nodes

Explains how to view the list of Nodes using either the Control System or the CLI.

Viewing the list of Nodes on the Control System

Note: The Nodes page is not available in the Kubernetes version of the Control System.

The page contains the following panes:

Node Health	Displays each node’s health.
Active Alarms	Displays active alerts for nodes in the cluster.
Current Resource Utilization	Plots the current CPU and memory utilization for each node as a graph. This helps visualize the nodes that utilize the most CPU and memory.
Nodes	Displays all the nodes in the cluster.

For each node in the cluster, the Nodes pane displays the following:

Column Name	Column Description
Health	The health of the node. Value can be: — Healthy — Degraded — Critical — Maintenance
Hostname	The hostname of the node.
Physical IPs	The physical IP address or addresses associated with the node.
Last FS Heartbeat	The time since the node's last heartbeat to the CLDB.
Memory Utilized	The amount of memory used by the node.
Memory Total	The total amount of memory on the node.
CPU Utilized	The CPU usage metric for the node.
Disk Utilized	The amount of disk space utilized on the node.
Total Disk Space	The total amount of disk space on the node.
Physical Topology	The rack path to the node.
Running Services	The number of services running on the node.

Selecting the checkbox beside a node makes the following buttons available:

The basic command to view all the nodes on a cluster is:

maprcli node list -cluster <cluster>
