Table 1‑29. Data Counters
Chart Label Description
Storage I/O Control
Normalized Latency
This is the latency that is monitored by Storage I/O Control to detect congestion on the
datastore.

Storage I/O Control Aggregate IOPs
This chart displays the number of I/O operations per second on the datastore, aggregated across all hosts
and virtual machines accessing the datastore. The chart displays zero values when Storage I/O Control is
disabled.
This chart is located in the Performance view of the datastore Performance tab. The datastoreIops counter
can also be displayed for datastore cluster charts.

Storage I/O Control Activity
This chart displays the percentage of time during which Storage I/O Control actively controlled the
datastore latency.
This chart is located in the Performance views of the datastore and datastore cluster Performance tabs.

Average Device Latency per Host
This chart displays the average amount of latency on a host device. The chart displays the ten hosts with the
highest device latency.
This chart is located in the Performance view of the datastore Performance tab.
