vRealize Operations collects datastore and disk space metrics for storage pod objects.

Storage Pod metrics include capacity and badge metrics. See definitions in:
Table 1. Datastore Metrics for Storage Pods
Metric Name Description
Read IOPS Average number of read commands issued per second during the collection interval.

Key: datastore|numberReadAveraged_average

Writes per second Average number of write commands issued per second during the collection interval.

Key: datastore|numberWriteAveraged_average

Read Throughput (KBps) Amount of data read in the performance interval.

Key: datastore|read_average

Write Throughput (KBps) Amount of data written to disk in the performance interval.

Key: datastore|write_average

Total Throughput (KBps) Usage Average.

Key: datastore|usage_average

Read Latency Average amount of time for a read operation from the datastore. Total latency = kernel latency + device latency.

Key: datastore|totalReadLatency_average

Write Latency Average amount of time for a write operation to the datastore. Total latency = kernel latency + device latency.

Key: datastore|totalWriteLatency_average

Total Latency (ms) The average amount of time taken for a command from the perspective of a Guest OS. This is the sum of Kernel Command Latency and Physical Device Command Latency.

Key: datastore|totalLatency_average

Total IOPS Average number of commands issued per second during the collection interval.

Key: datastore|commandsAveraged_average

Table 2. Disk Space Metrics for Storage Pods
Metric Name Description
Freespace Unused space available on datastore.

Key: diskspace|freespace

Total used Total space used.

Key: diskspace|disktotal

Capacity Total capacity of datastore.

Key: diskspace|capacity

Virtual Machine used Space used by virtual machine files.

Key: diskspace|used

Snapshot Space Space used by snapshots.
