Node View

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.

**Table 1** Node resource metrics
Metric	Unit	Description
Node CPU Rate	%	CPU usage of the node.
CPU Requests Commitment	%	CPU requests of the node/Total CPU of the node
CPU Limits Commitment	%	CPU limits/Total CPU of the node
Memory Usage	%	Memory usage of the node.
Memory Requests Commitment	%	Memory requests of the node/Total memory of the node
Memory Limits Commitment	%	Memory limits of the node/Total memory of the node
Pods CPU Rate	%	CPU usage of each pod on the node
Memory Usage	Bytes	Memory usage of the pod on the node

**Table 2** Node network metrics
Metric	Unit	Description
Receive Bandwidth	Bytes/s	The number of bytes received by the node per second.
Transmit Bandwidth	Bytes/s	The number of bytes sent by the node per second.
Network Receive Rate (Pod)	Bytes/s	The number of bytes received by each pod on the node per second.
Network Transmit Rate (Pod)	Bytes/s	The number of bytes sent by the pod on the node per second.
Rate of Received Packets	Count/s	The number of packets received by each pod on the node per second.
Rate of Transmitted Packets	Count/s	The number of packets transmitted by each pod on the node per second.
Rate of Received Packets Dropped	Count/s	The number of packets not received by each pod on the node per second.
Rate of Transmitted Packets Dropped	Count/s	The number of packets transmitted by each pod on the node but not received by the receiver per second.

**Table 3** Node disk metrics
Metric	Unit	Description
Node I/O Per Second (Reads + Writes)	Count/s	Total number of read and write operations performed by each pod on the disk per second.
Node I/O Throughput (Read + Write)	Bytes/s	Total number of bytes read from and written to the disk by each pod on the node per second.
