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.
| 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 |
| 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. |
| 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. |
