vRealize Network Insight collects datastore metrics to learn about storage space use and to check metric trends to identify spikes or abnormal growth.
| Metric Name | Metric API Name | Decription |
|---|---|---|
| Capacity | datastore.capacity.absolute.latest.bytes | Total storage capacity of the datastore. |
| Committed Space | datastore.committed.absolute.latest.bytes | Storage space on the datastore that is used by the virtual machine to store disks, logs, snapshots, and configuration files. |
| Free Space | datastore.freespace.absolute.latest.bytes | Free space available on the datastore. |
| Free Space Percent (%) | datastore.freespace.absolute.latest.percent | Ratio of free storage space to the total storage capacity on the datastore. |
| Provisioned Space | datastore.provisioned.absolute.latest.bytes | Storage capacity allocated for all VMs on the datastore. |
| Provisioned Space Percent (%) | datastore.provisioned.absolute.latest.percent | Ratio of the provisioned space to the total storage capacity for the datastore. |
| Read IOPS | datastore.numberReadAveraged.rate.average.number | Average number of read commands issued per second on the datastore. |
| Read Latency (ms) | datastore.weightedTotalReadLatency.absolute.average.millisecond | Average read latency over a period of 24 hours. |
| Read Rate (kbps) | datastore.read.rate.average.kiloBytesPerSecond | Read throughput averaged over a period of 24 hours. |
| RW IOPS | datastore.numberRWAveraged.rate.average.number | Average number of read and write commands issued per second over a period of 24 hours. |
| RW Rate (kbps) | datastore.usage.rate.average.kiloBytesPerSecond | Read and write throughput averaged over a period of 24 hours. |
| Uncommitted Space | datastore.uncommitted.absolute.latest.bytes | Additional storage space that is potentially used by the VM on the datastore. This storage space is needed for thin-provisioned VMs to allow lazily allocated disks to expand or storage for swap. |
| Used Space | datastore.usedspace.absolute.latest.bytes | Storage capacity used by VMs on the datastore. |
| Used Space Percent (%) | datastore.usedspace.absolute.latest.percent | Ratio of used storage capacity to the total storage capacity on the datastore. |
| Write IOPS | datastore.numberWriteAveraged.rate.average.number | Average number of write commands issued per second on the datastore. |
| Write Latency (ms) | datastore.weightedTotalWriteLatency.absolute.average.millisecond | Average write latency over a period of 24 hours. |
| Write Rate (kbps) | datastore.write.rate.average.kiloBytesPerSecond | Write throughput averaged over a period of 24 hours. |
