Performance View
The Performance view displays the following information about nodes in the cluster, including:
- Hlth - each node's health: healthy, degraded, critical, or maintenance
- Hostname - DNS hostname for the nodes in this cluster
- Memory - percentage of memory used and the total memory
- % CPU - percentage of CPU usage on the node
- # CPUs - number of CPUs present on the node
- Bytes Received - number of bytes received in 1 second, through all network interfaces on the node
Performance Metrics
| Metric | Description |
|---|---|
| Bytes Sent | The number of bytes sent in 1 second, through all network interfaces on the node. |
| # RPCs | The number of RPC calls. |
| RPC In Bytes | The number of RPC bytes received by this node every second. |
| RPC Out Bytes | The number of RPC bytes sent by this node every second. |
| # Disk Reads | The number of disk read operations on this node every second. |
| # Disk Writes | The number of disk write operations on this node every second. |
| Disk Read Bytes | The number of bytes read from all the disks on this node every second. |
| Disk Write Bytes | The number of bytes written to all the disks on this node every second. |
| # Disks | The number of disks on this node. |
| Gets - 1m | The number of data retrievals (gets) executed on this region's primary node in a 1-minute interval. |
| Puts - 1m | The number of data writes (puts) executed on this region's primary node in a 1-minute interval. |
| Scans - 1m | The number of data seeks (scans) executed on this region's primary node in a 1-minute interval. |
