How do events and event controls work?
Once you enable Events in the time controls, you can find these events in the charts that display Device, Local Traffic and Web Application Security data (), and in the charts that display specific application and BIG-IP device data ( or ).
Events displayed in statistics charts provide you with insights about changes in application traffic or device resource data that might require attention or mitigation. An event includes any non-statistical measure that is reported by your BIG-IP device. Events usually indicate how the system was disrupted as a result of traffic changes, changes in system objects, or attacks. You can use events to identify if and when a specific occurrence affected an object's performance.
This figure shows a close up of the event controls on a typical overview screen. To view a screen similar to this, click.

What does this control do?
This control displays, below the chart area, the events table, which lists all events that occurred at a specific time. Click an event indicator to display the event table.
The indicator number displays the number of detected events at that time. This number adjusts to reflect changes to the time focus.
Events are color-coded according to their Category color. When more than one event category event occurs at a time, the indicator shape changes. You can view the event category breakdown by hovering the cursor over the indicator, as shown in the figure.
Use this control to filter the events displayed in the chart by category. Each category indicates the type of the reported event.
Categories provide an organization structure that can indicate the nature or origin of each event. Each category is color-coded, and the number indicates the quantity of events from that category that are displayed in the chart. De-selecting a category (marked in gray) directly impacts the corresponding quantities in the log-levels and the events displayed in the chart.
Use this control to filter by log level the events that are displayed in the chart. Each log level indicates the severity of the reported event.
Log levels indicate the severity of each event. Log levels are listed in descending order of severity, where
