Option Evaluation Process
Created On Do the date and time stamps for the symptoms indicate that they were triggered before the alert you
are investigating, indicating that it might be a related symptom? Were the symptoms triggered after
the alert was generated, indicating that the alert symptoms contributed to these other symptoms?
Information Can you identify a correlation between the alert symptoms and the other symptoms based on the
triggering metric values?
What to do next
n
If your review of the symptoms and the provided information clearly indicates that the
recommendations will solve the problem, implement one or more of the recommendations. For an
example, of implementing one of the recommendations, see “Run a Recommendation On a Datastore to
Resolve an Alert,” on page 18.
n
If your review of the symptoms did not convince you that the recommendations will resolve the
problem or provide you with enough information to identify the root cause, continue your investigation
using the Timeline tab. See “Compare Alerts and Events Over Time in Response to a Datastore Alert,”
on page 15.
Compare Alerts and Events Over Time in Response to a Datastore Alert
To evaluate an alert over time, compare the current alert and symptoms for the datastore to other alerts and
symptoms, other events, other objects, and over time.
As a network operations engineer, you use the Timeline tab to compare this alert to other alerts and events
in your environment so that you can determine if you can resolve the problem of the datastore running out
of disk space by applying one or more alert recommendations.
Prerequisites
Verify that you are addressing the alert for which you received an alert message in your email. See
“Respond to an Alert in Your Email,” on page 13.
Procedure
1 In the left pane of vRealize Operations Manager, click the Alerts icon.
2 Click the alert name link.
The center pane view changes to display the alert detail tabs.
3 Click the Timeline tab.
The Timeline tab displays the generated alert and the triggered symptoms for the aected object in a
scrollable timeline format, starting when the alert was generated.
4 To determine if other alerts are generated for the object, click the other alert buons.
In this example, the datastore alert generated a Risk alert, so the other alerts to add to the timeline are
Health and Eciency. Scroll through the timeline using the week timeline at the boom.
5 To view events that might contribute to the alert, click Select Event Type and click the check box for
each event type.
Events related to the object are added to the timeline. You add the events to your evaluation of the
current state of the object and whether the recommendations can resolve the problem.
6 Click Show Ancestor Events and select Host.
Because the alert is related to disk space, adding the host to the timeline allows you to see what alerts
and symptoms are generated for the host. As you scroll through the timeline, when did some of the
related alerts begin? When are they no longer on the timeline? What was the eect on the state of the
datastore object?
