Using the System Event Dashboard : Dashboard tab
  
Dashboard tab
The Dashboard tab provides a top-level view of NetIM status, and provides the means to navigate down to root-cause events.
The accordion boxes for categories include:
Network Changes
Data Collection
Diagnostics
Device Availability
System Configuration
Poller and Metrics Collection
Maintenance
Within each accordion box, the Dashboard include a set of LEDs to show the status of specific events in that category. Some events show trees of LEDs so you can navigate to child LEDs.
By default, an LED shows the worst case status of its children. If one of many children is red, then the parent LED will be red. To see the details about any event, double-click the event or its LED to jump to the Event Details tab. When the Event Details tab appears, the chosen event will have the focus.
