Node View

Updated on 2025-01-07 GMT+08:00

The node view displays node resource, network, and disk metrics, so you can better monitor a node.

Metric Description

You can view the node metrics in the following tables.

Figure 1 Resource metrics
Table 1 Resource metrics

Metric

Unit

Description

Node CPU Usage

%

CPU usage of a node.

CPU Requests Commitment

%

Total CPU requests/Total CPU of the node

CPU Limits Commitment

%

CPU limits/Total CPU of the node

Memory Usage

%

Memory usage of a node.

Memory Requests Commitment

%

Total memory requests/Total memory of the node

Memory Limits Commitment

%

Memory limits/Total memory of the node

Pod CPU Usage

%

CPU usage of the pod on the node

Used Memory

byte

Memory usage of the pod on the node

Figure 3 Disk metrics
Table 3 Disk metrics

Metric

Unit

Description

Node Disk I/O Rate (Read + Write)

N/A

The number of read/write operations on the disk by the pod on the node per second.

Node Disk Throughput (Read + Write)

byte/s

Total number of bytes read from and written to the disk by the pod on the node per second.
