Storage counters at the datastore level

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

Storage counters at the datastore level

Datastore counters provided by vCenter

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)
  • Maximum Queue Depth per host (Top 10)
  • Read IOPS per host (Top 10)
  • Write IOPS per host (Top 10)
  • Average Read Latency per VM vDisk (Top 10)
  • Average Write Latency per VM vDisk (Top 10)
  • Read IOPS per VM vDisk (Top 10)
  • Write IOPS per VM vDisk (Top 10)

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, write, and total.
