Disk Metrics for Cluster Compute Resources
Disk metrics provide information about disk use.
Table 5-17. Disk Metrics for Cluster Compute Resources
Metric Key Metric Name Description
disk | commandsAveraged_average Commands per second Average number of commands issued per
second during the collection interval.
disk | totalLatency_average Disk Command Latency (ms) Average amount of time taken for a command
from the perpsective of the guest operating
system. This metric is the sum of the Kernal
Device Command Latency and Physical
Device Command Latency metrics.
disk | totalReadLatency_average Disk Read Latency Average amount of time for a read operation
from the virtual disk. The total latency is the
sum of kernal latency and device latency.
disk | totalWriteLatency_average Disk Write Latency Average time taken for a write from the
perspective of the guest operating system. This
metric is the sum of the Kernel Write Latency
and Physical Write Latency metrics.
disk | numberRead_summation Read Rate (KBps) Amount of data read during the collection
interval.
disk |
numberReadAveraged_average
Reads per second Average number of read commands issued per
second during the collection interval.
disk | usage_average Usage Rate (KBps) Average of the sum of the data read and
written for all of the disk instances of the host
or virtual machine.
disk | workload Workload (%) Percent workload.
disk | numberWrite_summation Write Rate (KBps) Amount of data written to disk during the
collection interval.
disk |
numberWriteAveraged_average
Writes per second Average number of write commands issued
per second during the collection interval.
disk | read_average Read Requests Number of times data was read from the disk
during the collection interval.
