Resource Pool. Number of Virtual Machines

This report aggregates historical data and shows the number of virtual machines (total and active) in selected resource pools across a time range.


The Resource Pool. Number of Virtual Machines report is a linked report that is based on the Veeam Performance Report from the Veeam Report Library.

The report features a predefined list of VM state performance counters. The object picker control for the report scope has a predefined filter which limits selection to Objects of the VMware Resource Pool class and Groups that include objects of the VMware Resource Pool class.


Data Aggregation: defines the aggregation period (Hourly or Daily).

Date/time Selection: defines the time period to analyze in the report.

Histogram: defines the type of values shown on the x-axis of the chart.

Split into sections by: defines whether the sections will be split by resource pools, selected groups/objects, or counters.

Chart Options: defines the type of an object for which a separate chart will be displayed. The list of available options depends on the Split into sections by value.

Scope: defines a list of Groups or Objects to analyze in the report. The Add Group option returns a Group and all objects that a group contains (with all performance counter instances). The Add Object option returns only the selected object.

Counters: defines collection rules for performance counters to analyze in the report.
