In the Splunk Web Interface, you can navigate to /manager/system/deploymentserver to get access to a set of tables that give you information on your deployment infrastructure. Namely, the Apps, Server Classes, and Clients.
Clicking on one of this tabs gives you a table that can be filtered on in a few ways. Is it possible to expose these tables in a Splunk search? I have done some investigation of the REST documentation, and nothing has stood out.
