As a virtual infrastructure administrator, you respond to customer complaints and alerts, and identify problems that occur on the objects in your environment. You use the information on the Symptoms tab to help determine whether the triggered symptoms indicate conditions that contribute to the reported or identified problem.
You must research a problem of poor performance on one of your virtual machines, as reported by one of your customers. When you view the Alerts tab for the virtual machine, the only alert that appears is named Virtual Machine is Violating Risk Profile 1 in vSphere Hardening Guide.
When you reviewed the Capacity tab for the virtual machine, you identified that problems were occurring with memory and disk space. Now, you focus your attention to the triggered symptoms on the virtual machine.
The following method of using the Symptoms tab to evaluate problems is provided as an example for using vRealize Operations Manager , and is not definitive. Your troubleshooting skills and your knowledge of the particular aspects of your environment determine which methods work for you.
- In the menu, click Dashboards, then click Troubleshoot a VM in the left pane.
- Search for a virtual machine to troubleshoot.
In this example, the virtual machine name is named sales-10-dk.
- With the virtual machine selected, click the Alerts tab, and click the Symptoms tab.
- Review and evaluate the triggered symptoms.
Option Evaluation Process Symptom Are any of the triggered symptoms related to the critical states you see for memory or disk space? Status Are the symptoms active or inactive? Even inactive symptoms can provide information about the past state of the object. To add any inactive symptoms, click Status: Active on the toolbar to remove the filter. Created On When did the symptoms trigger? How does the time of the triggered symptom compare with the other symptoms? Information Can you identify a correlation between the triggered symptoms and the state of the Time Remaining and Capacity Remaining badges?

- Independent nonpersistent disks are being used
- Autologon feature is enabled

- Virtual machine disk space time remaining is low
- Virtual machine CPU time remaining is low
- Guest partition disk space usage
- Virtual machine memory time remaining is low
