Example: Search progress events in HTML dashboards

This example uses a converted HTML Dashboard to retrieve the progress of a search, including the status of the search and the properties of the search job.

[example]

This example shows the modified code (which is highlighted) for a converted HTML dashboard, and the Simple XML code for the original dashboard.

To view this dashboard:

  1. Copy the HTML code, find and replace "APP_NAME" with your app name, then save the HTML file under an existing app in $SPLUNK_HOME/etc/apps/app_name/local/data/ui/html/.
  2. Refresh the Splunk Web server by going to http://<localhost:port>/debug/refresh and clicking Refresh.
  3. In Splunk Web, view the dashboard in your app. For example, to view myexample.html in mysplunkapp, go to http://<localhost:port>/app/mysplunkapp/myexample.

To recreate the example:

  1. Save the XML file under an existing app in $SPLUNK_HOME/etc/apps/app_name/local/data/ui/views/.
  2. Refresh the Splunk Web server by going to http://<localhost:port>/debug/refresh and clicking Refresh.
  3. In Splunk Web, open the dashboard in your app. For example, to view myexample.xml in mysplunkapp, go to http://<localhost:port>/app/mysplunkapp/myexample.
  4. Click ..., then click Convert to HTML.
  5. Click Shared for Permissions, click Convert Dashboard, then click Edit HTML.
  6. Modify the HTML as shown in the example, then click Save.

// In the require function, we include the necessary libraries and modules for

//
// When you add libraries or modules, remember to retain this mapping order
// between the library or module and its function parameter. You can do this by
// adding to the end of these lists, as shown in the commented examples below.
