Disk Performance History" dateModified: "2026-09-10" --- # Virtual Machines. Disk Performance History This report aggregates historical data and shows disk usage statistics for selected virtual machines across a time range. ## Description 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. ## Parameters 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. ## Sample Usage Report on disk usage rate for the selected VMs during this week. ### Instructions 1. Open the Virtual Machines. Disk Performance History report. 2. From the **Data Aggregation** list, select *Daily*. 3. From the **From** list, select *This Week* > *Monday*. From the **To** list, select *This Week* > *Friday*. 4. From the **Histogram** list, select *No*. 5. In the **Split into sections by** list, select *VMware Virtual Machine*. 6. In the **Scope** section, click **Add Group**. Click **Search** and select the necessary VMs. Click **Add** and click **OK**. 7. In the **One chart for** list, select *Counter*. 8. In the Counters list, select *VMGuest-disk\\usageRateKB/s (VMGUEST.Collect.totalDiskUsageRate)*. 9. Click **Run** to view the report. **Report Output** The report will show how the average disk usage rate has changed for the selected virtual machines during the week. The table will detail daily values for disk usage rate (sample count, average, minimum, maximum, and standard deviation values). You can click the **Instance: _Total** link in the output table to drill down to the [Veeam Performance Details Report](veeam_performance_details_report.md).
