Compare Symptoms on a Timeline When You Troubleshoot a Virtual Machine Problem
Looking at the triggered symptoms for an object over time allows you to compare triggered symptoms,
alerts, and events when you are troubleshooting problems with objects in your environment. The Timeline
tab in vRealize Operations Manager provides a visual chart on which to see triggered symptoms that you
can use to investigate problems in your environment.
After you identify the following symptoms as possible indicators of the root cause of the reported
performance problems on the sales-10-dk virtual machine, you compare them to each other over time,
looking for interesting or common paerns.

The following method of evaluating problems using the Timeline tab is provided as an example for using
vRealize Operations Manager and is not denitive. Your troubleshooting skills and your knowledge of the
particulars of your environment determine which methods work for you.
Prerequisites
Review the triggered object symptoms. See “Review the Triggered Symptoms When You Troubleshoot a
Virtual Machine Problem,” on page 46.
Procedure
1 Enter the name of the virtual machine in the Search text box, located on the main title bar.
In this example, the virtual machine name is sales-10-dk.
2 Click the Troubleshooting tab and click the Timeline tab.
3 On the Timeline toolbar, click Date Control and select a time that is on or before the reference
symptoms were triggered.
The default time range is the last 6 hours. For a broader view of the virtual machine over time,
congure a range that includes triggered symptoms and generated alerts.
4 To view the point at which the symptoms were triggered and to identify which line represents which
symptom, drag the timeline week, day, or hour section left and right across the page.
5 Click Select Event Type and select all the event types.
Consider whether events correspond to triggered symptoms or generated alerts.
6 In the Related Hierarchies list in the upper left pane, click vSphere Hosts and Clusters.
The available ancestors and descendant objects depend on the selected hierarchy.
