Description
Derived counters
Performance object type
For each virtual disk, this counter records the average
data transfer size of the read requests received during
the current sampling interval.
Average Read Size (KB)
Vdisk
For each virtual disk, this counter records the average
data transfer size of the write requests received during
the current sampling interval.
Average Write Size (KB)
Vdisk
For each virtual disk, this counter records the average
data transfer size of the I/O requests received during the
current sampling interval.
Average IO Size (KB)
Vdisk
For each virtual disk, this counter records the percentage
of the read requests (hit + miss) during the current
sampling interval.
Read Hit %
Vdisk
For each virtual disk, this counter records the weighted
average value of the read latency weighted with number
of I/O requests during the current sampling interval.
Average Read Latency (ms)
Vdisk
For each virtual disk, this counter records the weighted
average value of the latency for I/O requests (both read

and write) received weighted during the current sampling
interval.
For each virtual disk group, this counter records the total
I/O requests received during the current sample interval.
Total Req/s
VDISK GRP
For each virtual disk group, this counter records the total
data rate (read and write data rate) during the current
sample interval.
Total MB/s
VDISK GRP
For each virtual disk group, this counter records the total
data rate during the current sample interval. It includes

all the read requests, regardless of whether they resulted
in a cache hit or a cache miss.
For each virtual disk group, this counter records the total
read requests received during the current sample interval.
