I am a neophyte to both Splunk and Servicenow. I have installed your app, and ran a few examples. Works great, nice job. It has fallen to me to integrate the two, and so far so good. But I am stuck on understanding how to leverage your app in regards to aggregate. There is is precious little knowledge, and I assume this is something I should know, but don't. Could you offer a novice explanation with a couple of novice examples please?
There doesn't appear to be much information on how to use aggregate functions for ServiceNow, after glancing through the ServiceNow wiki. There are examples of how to use some of the aggregate functions (i.e. SUM, AVG, COUNT, MIN, MAX) with "having" and "group by" clauses. Here's a link to the wiki that describes aggregates and provides examples:
The in-app help for the ServiceNow app provides an example of how to use aggregates within Splunk. Note that you will also need to activate the Aggregate Web Services Plug-In in your ServiceNow portal:
