The Event Count dashlet displays the count of events for the selected applications, groups, or devices based on the specified status, severity, and advanced filtering options. The dashlet displays the count of events in a stacked, or Column chart, or in a segmented, or Bar chart. The charts plot event count against severity while the stacks or segments indicate the status of those events.
Click the data points to open the Events page where individual events are listed. The events are filtered based on criteria you selected from the Configuration page. For more information see viewing event details and understanding event states.
At least one instance of a TrueSight Infrastructure Manager server must be registered with the Presentation Server for this dashlet template to be available.
You can configure this dashlet when you add or edit a dashboard.
Click the Configure Dashlet icon.

In the Event Count dashlet, the column chart data is stacked and the bar chart data is segmented. This section contains more information about understanding the dashlet data.
All the events that are in the Open status for all severity types are marked in color and appear in the bottom stack of a column chart or left segment of a bar chart. All other statuses (not Open) appear in shades of the color gray. If you hover over a data point, a tooltip displays the status. The following table shows the colors and their meanings:
|Critical events that have the status Open
|Major events that have the status Open
|Minor events that have the status Open
|Warning events that have the status Open
|Informational events that have the status Open
|OK events that have the status Open
|Events of unknown type and have the status Open
|Events with status Acknowledged (applicable to all severities)
|Events with status Assigned (applicable to all severities)
|Events with status Blackout (applicable to all severities)
|Events with status Closed (applicable to all severities)
If a chart displays only gray segments, no events are in Open status. The total number of events for each severity is displayed at the top of the columns and to the extreme right of the bars. A total count of 0 indicates that there are no events under that severity. Total counts are not displayed for dashlets configured for only one status type or if only status type is available. See the following figure for an example:
You can restrict the number of columns or bars by configuring the dashlet to display fewer severity and status types.
