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 56.
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.
7 To see if the host is experiencing a contributing problems, click Show Ancestor Events.
Consider whether the host has symptoms, alerts, or events that provide you with more information
about memory or disk space issues.
Comparing virtual machine symptoms to host symptoms, and looking at the symptoms over time indicates
the following trends:
n
The host resource usage, host disk usage, and host CPU usage symptoms are triggered for about 10
minutes approximately every 4 hours.
n
The virtual machine guest le system out of space symptom is triggered and canceled over time.
Sometimes the symptom is active for an hour and canceled. Sometimes it is active for two hours. But no
more than 30 minutes occur between cancellation and the next triggering of the symptom.
What to do next
Look at events in the context of the analysis badges and alerts. See “Identify Inuential Events When You
Troubleshoot a Virtual Machine Problem,” on page 59.
