vRealize Operations Manager 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 Key

Metric Name

Description

datastore|numberReadAveraged_average

Reads per second

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

datastore|numberWriteAveraged_average

Writes per second

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

datastore|read_average

Read Rate

Amount of data read in the performance interval.

datastore|write_average

Write Rate

Amount of data written to disk in the performance interval.

datastore|usage_average

Usage Average

Usage Average.

datastore|totalReadLatency_average

Read Latency

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

datastore|totalWriteLatency_average

Write Latency

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

datastore|totalLatency_average

Disk Command Latency

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.

datastore|commandsAveraged_average

Commands per second

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

Table 2. Diskspace Metrics for Storage Pods

Metric Key

Metric Name

Description

diskspace|disktotal

Total used

Total space used.

diskspace|freespace

Freespace

Unused space available on datastore.

diskspace|capacity

Capacity

Total capacity of datastore.

diskspace|used

Virtual Machine used

Space used by virtual machine files.

diskspace|snapshot

Snapshot Space

Space used by snapshots.
