Virtual Machines. Disk Performance History

This report aggregates historical data and shows disk usage statistics for selected virtual machines across a time range.


The Virtual Machines. Disk Performance History 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 disk usage performance counters. The object picker control for the report scope has a predefined filter which limits selection to Objects of the VMware Virtual Machine class and Groups that include objects of the VMware Virtual Machine 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 VMs, 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.
