Viewing event details in the Events Timeline

You can view all performance events and their related details in the Events Timeline pane of Performance Explorer. This is a quick and efficient method of viewing all the threshold events that occurred on the root object during a specified time range, which can be helpful when troubleshooting performance issues.

About this task

The Events Timeline pane shows critical, warning, and informational events that occurred on the root object during the selected time range. Critical events are sent when a critical limit in a threshold policy is exceeded. Warning events are sent when a warning limit in a threshold policy is exceeded, or when dynamic thresholds are exceeded. Informational events are sent when ONTAP configuration change events occur.

Critical, warning, and informational events have their own timelines. Single and multiple events are represented by an event point on the timeline. You can position your cursor over an event point to see the event details. To increase the visual granularity of multiple events, you can decrease the time range. This spreads out multiple events into single events, enabling you to separately view and investigate each event.

The event points on the Events Timeline line up vertically with their corresponding spikes in the counter charts trend lines that are displayed below the Events Timeline. This provides a direct visual correlation between events and overall performance.


  1. On the Events Timeline pane, position the cursor over an event point on a timeline to view a summary of the event or events at that event point.
    A pop-up dialog displays information about the event types, the date and time when the events occurred, the state, and the event duration.
  2. View full event details for one event or multiple events:
