Viewing Node Information

To monitor the resource usage of nodes, go to the Nodes tab. This tab provides information about all nodes in a cluster and monitoring data of a node, such as the CPU usage, memory usage, network inbound rate, network outbound rate, disk read rate, and disk write rate.

Navigation Path

Log in to the UCS console.
In the navigation pane, choose Container Intelligent Analysis. Choose Container Insights > Clusters, click the cluster name in Cluster Overview, and click the Nodes tab.

This tab displays information about all nodes. To view the monitoring data of a node, click the node name to access its Overview tab and switch to the Pods or Monitoring tab to view the corresponding data.

Viewing the Node List

The node list displays the name, status, IP address, number of pods (allocated/total), CPU request/limit/usage, and memory request/limit/usage of each node.

You can search for the desired node by name, status, private IP address, or public IP address. You can click in the upper right corner of the list to export data of all nodes or selected nodes. The exported file is in .xlsx format, and the file name contains the timestamp.

Node Overview displays the name, status, CPU usage, memory usage, cluster, IP address, and region of each node. You can click the search box above the list, select a property type, and enter a keyword to search for the desired node.

If the CPU limit or memory limit of a node exceeds 100%, the node resources are overcommitted and the sum of workload limits (maximum available values) of the node exceeds the node specifications. If a workload occupies too many resources, the node may be abnormal.

Viewing Node Details

In the node list, click the node name to to access its Overview page and switch to the Pods or Monitoring tab to view the corresponding data.

**Table 1** Modules on the node details page
Module	Description
Overview	You can click the node name to access this tab. On this tab, you can view: Resource Overview: displays the node status and number of pods as well as abnormal events. Node Monitoring: displays the monitoring data in the last hour, last 8 hours, last 24 hours, and custom period, including the CPU usage, memory usage, and network inbound/outbound rate. Pod Usage Trend: displays top 5 pods by used CPU and memory in the last hour, last 8 hours, last 24 hours, and custom period.
Pods	This tab lists the name, status, namespace, IP address, node, number of restarts, CPU request/limit, memory request/limit, CPU usage, and memory usage of each pod. You can search for the desired pod by name, status, namespace, IP address, or node. You can click in the upper right corner of the list to export data of all pods or selected pods. The exported file is in .xlsx format, and the file name contains the timestamp. You can click the name of a pod to view its detailed monitoring data. For more information, see Viewing Pod Information.
Monitoring	This tab displays the resource usage of the node in each dimension in the last 1 hour, last 8 hours, last 24 hours, or a custom period. To view more monitoring information, click View Dashboard to access the Dashboard tab. For details, see Dashboard.
