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 48.
Identify Influential Events When You Troubleshoot a Virtual Machine Problem
Events are changes to objects in your environment that are based on changes to metrics, properties, or
information about the object. Examining the events for the problematic virtual machine in the context of the
analysis badges and alerts might provide visual clues to the root cause of a problem.
As a virtual infrastructure administrator investigating a reported performance problem with a virtual
machine, you compared symptoms on the timeline and identied interesting behavior around the guest le
system that you want to examine in the context of other badge metrics to determine if you can nd the root
cause of the problem.
The following method of evaluating problems using the Events 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
Examine triggered symptoms, alerts, and events over time. See “Compare Symptoms on a Timeline When
You Troubleshoot a Virtual Machine Problem,” on page 47
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 Events tab.
3 On the Events toolbar, click Date Control and select a time that is on or before the symptoms were
triggered.
4 Click Select Event Type and select all of the event types.
Consider whether any changes correspond to other events.
5 Click Show Parent Events and click through the badges on the toolbar to review the events.
Consider whether any of the events, which are listed in the data grid below the chart, correspond to
problems with the host that might contribute to the reported problem.
6 Click Show Child Events and click through the badges on the toolbar to review the events.
Consider whether any of the events show problems with the datastore.
Your evaluation shows no particular correlation between the workload or anomalies and the time at which
the guest le system out of space symptom was triggered each time.
