The Top Impacted Devices dashlet displays the top impacted devices in your IT environment as a chart based on the event severity. The event count from different severities against each top impacted device is shown in the bar segments. Tooltips are available on the dashlet.

On the bar chart, click any bar segment to open the Device Details page, as shown in the figure.

Dashlet requirements

At least one instance of a TrueSight Infrastructure Manager server must be registered with the Presentation Server for this dashlet template to be available.

Configuring the dashlet

You can configure this dashlet when you add or edit a dashboard.

  1. Click Add Dashlet and select the Top Impacted Devices dashlet.
  2. Click the Configure Dashlet  icon.

  3. Enter a meaningful and descriptive Title for the dashlet.
  4. From the Refresh Rate list, select a frequency for refreshing the chart view.
    The default is 5 minutes.

  5. In the Device Filter section, select from one of these options to filter for the event count:
    • Applications (All or Selected) 

    • Groups (All or Selected)

    • Device Types (All or Selected)

      For the Selected option, click the  link to search for and add the applications, groups, or device types. A  link is displayed after you selected the applications, groups, or device types. Click the   link to change the selected applications, groups, or device types.

      Differentiating between the All and Select All options

      In the Device Filter section there is a difference in behavior between choosing the All Groups or All Device Types and choosing the Select All option from the Groups and Device Types search dialog boxes.

      • Choose All to select all the groups or devices that are currently in TrueSight. This list changes automatically as groups or devices are added or removed.
      • Choose Select All to select only the items that are returned from a search. The list of groups or devices does not change.

      See the figure for an example.


      If the dashboard user selects an application from the Applications list at the dashboard level, then that selection is honored and takes precedence over the choices selected in this step.


      It is possible that one or more of the seleted applications, groups, or device types were deleted from the TrueSight server after they were selected. In that case, a red colored check box is displayed adjacent to the name of that application, group, or device type as shown in this figure.

  6. From the Status list, select one or more event status to display: OpenAcknowledged,AssignedBlackout, and Closed.
    By default 
    OpenAcknowledged, and Assigned are selected.

    From the Severity list, select one or more event severity to display: CriticalMajor,MinorWarning, and Information.
    By default, 
    CriticalMajor, and Minor are selected.


    If no Status or Severity is selected, all types are displayed.


  7. Select the height of the dashlet row: 1X2X, or 3X
    The value of X is approximately 100 pixels. The default height is 2X.

  8. Click Apply to add the configured dashlet to the dashboard.

    Best practice

    After you save the dashlet, change the dashboard row size settings to 50% layout or larger.
