Storage Path Counters

Performance counters are modeled using the PerfCounterInfo data object type. Each instance of a PerfCounterInfo data object contains metadata about a specific metric available from the system. The storage path group of performance counters supports real-time performance metrics (such as latency and read- and write-speeds) for I/O operations on a storage path.

Average number of read commands issued per second on the storage path during the collection interval.

Average number of write commands issued per second on the storage path during the collection interval.
totalReadLatency absolutemillisecond3averageRead latency οοο
Average amount of time for a read issued on the storage path. Total latency = kernel latency + device latency.
totalWriteLatency absolutemillisecond3averageWrite latency οοο
Average amount of time for a write issued on the storage path. Total latency = kernel latency + device latency.
