This report aggregates historical performance data for datastores and virtual machines in selected datastore clusters. The report shows top or bottom objects for a specific performance counter across a time range.
The Datastore Cluster. Top (Bottom) N Contained Objects or Instances is a linked report that is based on the Veeam Performance Top (Bottom) N Report from the Veeam Report Library.
The report features a predefined list of datastore and VM guest performance counters. The object picker control for the report scope has a predefined filter which limits selection to Objects of the VMware Datastore Cluster class and Groups that include objects of the VMware Datastore Cluster class.
Date/time Selection: defines the time period to analyze in the report.
Algorithm: defines whether top or bottom performing objects and/or performance counter instances will be displayed in the report.
Count: defines the number of top or bottom objects and/or performance counter instances that will be included in the report. The value can range between 1 and 200.
Group by: defines how data will be grouped in the report (by Object, Counter Instance or Object and Counter Instance).
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.
Counter: defines a collection rule for a performance counter to analyze in the report.
Report on top 10 virtual machines with the largest snapshot sizes stored on the selected datastore.
- Open the Datastore Cluster. Top (Bottom) N Contained Objects or Instances report.
- From the From list, choose This Week > Monday. From the To list, choose This Week > Friday.
- From the Algorithm list, choose Top.
- In the Count field, type 10.
- From the Group by list, choose Object.
- In the Scope section, click Add Group. Click Search and select the necessary datastore. Click Add and click OK.
- From the Counter list, select VMGuest\snapshotsSizeMB (VMGUEST.Collect.snapshotSize).
- Click Run to view the report.
The report will show 10 VMs with the largest snapshots.
The chart will display the following details for every VM: snapshot size and the minimum-to-maximum size range for the selected period.
The table will display additional details for every VM: VM name, sample count, minimum, maximum and average snapshot size values, and standard deviation.
If several objects have the same ranking function value, the report will include more objects than you have set in the Count field. For example, the “bottom 10” report will show 11 objects if two objects “share” the same position (have the same value).
You can click VM names in the output table to drill down to the Veeam Performance Details Report.
