qos_volume
The workload_volume table provides workload statistics on a per volume basis. Workload information at a file or LUN level are not shown by this table (See the workload table). This table provides information such as operations per second, a breakdown of where read operations are going, the interarrival time of operation request messages, working set size information, operation latency per workload, and deferred workload information.
