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.

Before you begin

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.

About this task

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.

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 affected 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 buttons.

    In this example, the datastore alert generated a Risk alert, so the other alerts to add to the timeline are Health and Efficiency. Scroll through the timeline using the week timeline at the bottom.

  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 effect on the state of the datastore object?

  7. Click Show Peer Events.

    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 in your environment.

  8. To remove canceled alerts from your timeline, click Select Status and deselect the Canceled check box.

    Removing the canceled alerts and symptoms from the timeline clears the view and allows you to focus on current alerts.
