The generated alerts, triggered symptoms, and change events for the current object over time appear on the Timeline tab. You use the timeline to identify common trends over time that are contributing to the status of objects in your environment.
How the Events Timeline Works
The timeline view includes alerts, symptoms, and events for the selected object for the last 6 hours. To view the data for a particular time, click the timeline in one of the three tiers. Then move your mouse to the left to see data from the past or to the right to move back to the present.
The view is limited to approximately 50 alerts, symptoms, and events. If your timeline includes more than this number, you can use the toolbar options to remove data from the timeline until it contains data that you find useful for your investigation.
