VM Datastore Metrics

Virtual Machine Datastore metrics provide information about the performance of the link that connects the datastore to the VM.

Metric Name	Metric API Name	Decription
Committed Space	datastore.committed.absolute.latest.bytes	Storage space on the datastore that is commited for this link.
Read IOPS	datastore.numberReadAveraged.rate.average.number	Average number of read commands issued per second during the collection interval.
Read Latency (ms)	datastore.totalReadLatency.absolute.average.millisecond	Average latency of each read operation issued by the link through which the host is connected to the datastore.
Read Rate (Kbps)	datastore.read.rate.average.kiloBytesPerSecond	Average number of kilobytes read by the link through which the host is connected to the datastore.
RW IOPS	datastore.numberRWAveraged.rate.average.number	Average number of read and write commands issued per second during the collection interval.
RW Rate (Kbps)	datastore.usage.rate.average.kiloBytesPerSecond	The aggregated input rates and output rates of the link through which the host is connected to the datastore.
Write IOPS	datastore.numberWriteAveraged.rate.average.number	Average number of write commands issued per second during the collection interval.
Write Latency (ms)	datastore.totalWriteLatency.absolute.average.millisecond	Average latency of each write operation issued by the link through which the host is connected to the datastore.
Write Rate (Kbps)	datastore.write.rate.average.kiloBytesPerSecond	Average number of kilobytes written by the link through which the host is connected to the datastore.
