Creating widgets from a Dynamic query data source

The Dynamic Search data source uses the IBM® QRadar® dynamic search API to search for data that involves aggregated functions such as COUNT, SUM, MAX, and AVG. For example, you can count the number of asset IDs per asset hostname by using the COUNT_PER function.

1. Click Configure dashboard.

   The Configure dashboard screen displays a library of available widgets, with details about each widget.

2. Click Create new widget.
3. On the New Dashboard Item page, enter a name and a description for the widget.
4. Select Dynamic Search from the data source list in the Query section, and enter a JSON query.
5. Optional: If the QRadar version is 7.4.3 or later and you are an administrator, click the Dynamic search query builder link to build a query.
   1. Select a Data Source.
   2. Complete the Available Columns and Available Filters sections.
   3. To add a name, description, range of the search, retention period, or search type to your query, enable one or more Extra Search Properties.
   4. To copy your JSON script, click Generate JSON.
      Your results appear in the JSON generated by your query section. Click Copy to Clipboard to copy your JSON script.
   5. In the New Dashboard Item page, paste the copied JSON script.
6. Optional: Add parameters to the dynamic search query.
   1. Insert existing parameters in the query. Click the Insert Parameter icon, and then click Insert for each relevant parameter.
      Important: In dynamic search queries, parameters must be preceded with a dollar sign (for example, ${NumberOfRules}).
   2. To change the default value of the parameter, click the View Parameters icon, and click Save after you set the default value.
      When you change the default value for a parameter, you're changing the value everywhere the parameter is used in your workspace, except in expanded or pinned dashboards and widgets. If you don't set the value as the default value, the updated change applies only to the current session. However, if you set the value as the default, the current session value also uses that value.

      The predefined SYSTEM:username parameter returns the username of the user who is logged in. System parameters are read only and you cannot change the default value.

   3. To add a parameter to your workspace, click Add, give the parameter a name and default value, if needed, and then click Save.

      After you add parameters to a widget on a dashboard for the first time, the Parameters card appears on the dashboard. If you remove parameters from the widget, and no other widget in that dashboard uses the parameter, the Parameters card disappears.

7. Click Run Query.
   When you first create the widget, you can't configure the charts when no data results are returned. Try making the criteria in the fields less strict and run the query again.
8. Create a dashboard chart in the Views section.
   Because you can create multiple views and charts from the same query, give the view a unique name. By default, the chart's title and status on the title bar are displayed; to hide them, click the More options icon and switch the settings to Off.
9. Select a chart type and configure the relevant properties. For use cases to help you decide which chart type to use, see Widget chart types.

10. Preview how the chart looks and then click Save.
    Tip: The labels for the chart come from the queries that are used. If they are unintelligible in the preview, edit the labels in the View section.
