Compare Alerts and
Events Over Time in Response to a Datastore Alert
To evaluate an
alert over time, compare the current alert and symptoms to other alerts and
symptoms, other events, other objects, and over time.
Verify that you are addressing
the alert for which you received an alert message in your email. See

As a network operations
engineer, you use the
tab to compare this alert to other alerts
and events in your environment. This way, you can determine if you can resolve
the problem of the datastore running out of disk space by applying one or more
alert recommendations.
- From the left menu, clickTroubleshootand then clickAlerts. Select the alert name in the data grid.The alert details appear to the right.
- Click .TheTimelinetab displays the generated alert and the triggered symptoms for the affected object in a scrollable timeline format, starting when the alert was generated.
- Scroll through the timeline using the week timeline at the bottom.
- To view events that might contribute to the alert, clickEvent Filtersand 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 determine whether the recommendations can resolve the problem.
- ClickView Fromand selectHostunder Parents.Because the alert is related to disk space, adding the host to the timeline helps you to see what alerts and symptoms are generated for the host. As you scroll through the timeline, ask: when did some of the related alerts begin? When are they no longer on the timeline? What was the effect on the state of the datastore object?
- ClickView Fromand selectPeerunder Parents.If other datastores have alerts related to the alert you are currently investigating, seeing when the alerts for the other datastores were generated can help you determine what resource problems you are experiencing.
- To remove canceled alerts from your timeline, clickFiltersand deselect theCanceledcheck box.Removing the canceled alerts and symptoms from the timeline clears the view and helps you to focus on current alerts.
- If your evaluation of alerts in the timeline indicated that one or more of the recommendations to resolve the alert are valid, implement the recommendations. See Run a Recommendation on a Datastore to Resolve an Alert.
- If you need more information about the affected object, continue your investigation. See View the Affected Datastore in Relation to Other Objects.
