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 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.

Key: diskspace|snapshot
