To run this report: 1. Open the **vSphere Hosts. Number of Virtual Machines** report. 2. From the **Data Aggregation** list, select *Daily*. 3. From the **From** list, select *This month* > *First day*. From the **To** list, select *This month* > *Last day*. 4. From the **Histogram** list, select *No*. 5. In the **Split into sections by** list, select *VMware vSphere Host*. 6. In the **Scope** section, include the necessary host in the report. 7. From the **One chart for** list, select *Counter*. 8. In the **Counters** list, select *VMHost\\vmActive (HOST.Collect.vmActive) and VMHost\\vmTotal (HOST.Collect.vmTotal)*. 9. Click **Run** to view the report. [![vSphere Hosts: Number of Virtual Machines Report Settings](images/number_of_vms_controls.png "vSphere Hosts: Number of Virtual Machines Report Settings")](images/number_of_vms_controls.png){.toggle scale=65} The report will show how the total number and number of active VMs have been changing for the selected vSphere host during the month. In this example, the report shows that the number of active VMs increased significantly on 04.04. and then stayed without any changes after 06.04.
