Virtual Disk 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 virtual disk group of performance counters supports real-time performance metrics (such as latency and read- and write-speeds) for I/O operations on virtual disks.

Average number of read commands issued per second to the virtual disk during the collection interval.

Average number of write commands issued per second to the virtual disk during the collection interval.
totalReadLatency absolutemillisecond2averageRead latency οοο
Average amount of time for a read operation from the virtual disk. Total latency = kernel latency + device latency.
totalWriteLatency absolutemillisecond2averageWrite latency οοο
Average amount of time for a write operation to the virtual disk. Total latency = kernel latency + device latency.
