The -G option of the vxstat command provides a detailed view of the IOPS statistics for an application volume group. You can obtain a detailed view of the statistics per second or an average of the accumulated statistics per second over a specified time interval.
For clustered environments, the detailed statistics is displayed for each node in the cluster.
See the vxstat(1M) manual page.
You can view the following information:
For example, to view the IOPS statistics per second for existing application volume groups:
# vxstat -g oradg -G <<<< average per second output
