The generated alerts, triggered symptoms, and change events for the current object over time appear on the Timeline display. You use the timeline to identify common trends over time that are contributing to the status of objects in your environment.

How the Timeline Display Works

The Timeline works by combining the data for alerts, symptoms and events and displaying it in a unified view. By default only active items are shown, however you can customize the data for each independently tab by using the filters to the top right and from the INCLUDE menu, which allows you to use parent, child and peer options to examine the object in a broader environmental context, as it is not always effective to investigate a problem on an individual object by looking only at the object. This context often reveals unexpected influences or consequences for the problem.

The timeline is a tool that provides you a graphical view of patterns. If the system triggers a symptom and then cancels it at various intervals over time, you can compare the event to other changes to the object or to the related objects. These changes might be the root cause of the problem.

The view is limited to 700 alerts, symptoms, and events accordingly. If your timeline includes more than this number, you can use the filters in each tab to remove data from the timeline until it contains data that you find useful for your investigation.
