You got it sorted; however some of this information is in the tutorials? Have
you had a go through the tutorials ...
<p>
I *would* like to make a tutorial for the graph module; but in general I need a
friend on the user list here in order to try out the result and tell me if it
makes sense. It sounds like you are working through the graph api at reasonable
clip; let me know if you would be able to volunteer in this capacity.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
