The vCenter adapter instance collects datastore and disk space metrics for storage pods.

Storage Pod metrics include capacity and badge metrics. See definitions in:

Capacity and Project-Based Metrics

Badge Metrics

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.

Diskspace Metrics for Storage Pods

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
