vSphere Basic System Administration Collection Level V H R C D 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. 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. NOTE 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. This appendix includes the following topics: n "Cluster Services Metrics," on page 326 n "CPU Metrics," on page 327 n "Disk Metrics," on page 331 n "Management Agent Metrics," on page 335 n "Memory Metrics," on page 336 n "Network Metrics," on page 344 n "Storage Utilization Metrics," on page 346 n "System Metrics," on page 347 n "Virtual Machine Operations Metrics," on page 348 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. NOTE The cluster services metrics appear only in the advanced performance charts. 326 VMware, Inc.
