Storage counters at the datastore level

vCenter only provides the following screen for datastores. It is a fixed set of charts with a fixed configuration.

The complete list of charts available in vCenter is listed as follows:

Storage I/O Control Normalized Latency
Storage I/O Control Normalized Aggregate IOPS
Average Device Latency per host (Top 10 only)
Maximum Queue Depth per host (Top 10 only)
Read IOPS per host (Top 10 only)
Write IOPS per host (Top 10 only)
Average Read Latency per VM vDisk (Top 10 only)
Average Write Latency per VM vDisk (Top 10 only)
Read IOPS per VM vDisk (Top 10 only)
Write IOPS per VM vDisk (Top 10 only)

As you can see, this list is rather limited. For example, there are no counters for throughput, be it read, write, or total. Most charts only show the top 10 data points.

vRealize Operations provides a richer set of data for storage at the datastore level, including IOPS, throughput, latency, and outstanding I/O. For most of them, you get the data for Read...
