Collection Level
Indicates the minimum value to which the statistics collection level must be set
for the metric to be gathered during each collection interval. You can assign a
collection level of 1 to 4 to each collection interval enabled on your vCenter
Server, with 4 containing the most data counters.
V H R C D
Indicates the entity for which the counter applies. One of:
n
V – virtual machines
n
H – hosts
n
R – resource pools
n
C – compute resources
n
D – datastores
Calculations for all metrics listed in the data counter tables are for the duration of the data collection cycle.
Collection cycle durations are specified with the Statistics Collection Interval setting.
N
OTE
The availability of some data counters in the vSphere Client depends on the statistics Collection Level
set for the vCenter Server. The entire set of data counters are collected and available in vCenter Server. You
can use the vShpere Web Services SDK to query vCenter Server and get statistics for all counters. For more
information, see the VMware vSphere API Reference.

Cluster Services Metrics
The cluster-services metric group (clusterServices) tracks performance statistics for clusters configured by
using VMware DRS (distributed resource scheduler), VMware HA (high availability), or both.
Table C-1
lists the cluster services data counters.
N
OTE
The cluster services metrics appear only in the advanced performance charts.
