You get a call from a user. Her computer is slow—can you fix it, please? The first thing that you want to determine is whether the computer really *is* slow. If yes, the next thing you want to find out is what slows the computer down.

The **Computer Overview** dashboard (**Dashboards > Computer Overview**) has a [Computer Event Timeline Widget](/performanceguard/dashboards-and-widgets/widgets/computer-event-timeline-widget/) that makes it easy to determine if a selected computer has had performance problems. If it has, the widget makes it easy to see exactly which problems the computer has had, and exactly when they happened.

The widget looks at events that have happened on the selected computer, and displays them as bubble markers on a timeline. Remember what an event is? It's a threshold violation, for example a response time that isn't acceptable. You can zoom in on relevant events and click the bubbles to view details.
