statistics volume show
Volume throughput and latency metrics
Availability: This command is available to cluster and Vserver administrators at the admin privilege level.
Description
This command continuously displays performance data for volumes at a regular interval. The command output displays data in the following columns:
- 
Volume - volume name.
 - 
Vserver - vserver name.
 - 
Aggregate - aggregate 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.
 
Parameters
[-volume <text>]- Volume- 
Selects the volume for which you want to display performance data.
 [-vserver <vserver name>]- Vserver- 
Selects the vserver for which you want to display performance data.
 [-aggregate <text>]- Aggregate- 
Selects the aggregate for which you want to display performance data.
 [-sort-key <text>]- Column to Sort By- 
If this parameter is specified, the command displays statistics sorted by the specified column.
 -interval <integer>- Interval- 
Specifies, in seconds, the interval between statistics updates. The default setting is 5 seconds.
 -iterations <integer>- Iterations- 
Specifies the number of iterations the command runs before terminating. The default setting is 1. If the number is 0 (zero), the command continues to run until you interrupt it by pressing Ctrl-C.
 -max <integer>- Maximum Number of Instances- 
Specifies the maximum number of volumes to display. The default setting is 25.
 
Examples
The following example displays volume statistics:
cluster1::> statistics volume show
cluster1 : 12/31/2013 16:00:04
