Accessing VMware Performance Reports

 

OpManager monitors all the critical parameters of your VMware servers and allows you to generate reports on the collected value. It provides over 70 different reports out-of-the-box, helping you get an insight into the performance trend and top hosts and VMs. All these reports are grouped under host reports & Virtual Machines reports. Further, they are subdivided based on system resources such as CPU, Memory, Network & Disk. The complete list of reports supported by OpManager is given in Table 3 for reference.

Host Reports:


View the reports for resources such as CPU, Memory, Network & Disk. Moreover, OpManager offers views to compare the performance of each VMs in a host. Say for example, when you see a gradual rise in Host CPU utilization trend, it would be useful to know which VM got affected due to the rise in physical resource. This information helps you quickly identify and fix the problem. With OpManager, you can select 'per VM' view (refer the screenshot given below) to compare the performance of VMs in that host.

Host reports

VM Reports:


VM Reports offer reports for each individual VMs. Refer the screenshot given below.
vm-reports

Accessing Reports:

You can generate reports from the snapshot page or directly access the Reports tab. For ease of use, all the reports of the VMs and hosts are grouped under Virtual Devices category under the Reports tab. Click on the report name to generate the report.
Virtual-device-reports

Example: The screenshot below shows the memory used report for a host. You can select the required performance report from the Select Report dropdown menu. If you wish to view the report for another host, select the required host from For Host dropdown menu. To view the amount of memory used by each VM, select the per VM check box.

The screenshot below shows the legend summary and table view. Legend summary provides the minimum, maximum and average values of memory used by the host. Table view provides the same values collected during the recent polls.

The reports can be exported to PDF or XLS format. You can also schedule reports and email them.
