Vserver throughput and latency metrics
Availability: This command is available to cluster administrators at the admin privilege level.
Description
This command continuously displays performance data for Vservers at a regular interval. The command output displays data in the following columns:
Vserver - Vserver name.
Total Ops - total number of operations per second.
Read Ops - read operations per second.
Write Ops - write operations per second.
Other Ops - other operations per second.
Read (Bps) - read throughput in bytes per second.
Write (Bps) - write throughput in bytes per second.
Latency(us) - average latency for an operation in microseconds.

- -max <integer> - Maximum Number of Instances
- Specifies the maximum number of Vservers to display. The default setting is 25.
Examples
The following example displays Vserver statistics:
