Wait step using correlation - NEW!

[Edward Diehl]

Hi Jake,

It's been a long time since I played around with correlations.  I have never had the opportunity to actually put one in production.  I put a blog on SDN covering the whole process of setting up a correction.  As a part of developing the blog I built a prototype that did work.  Let me see if I can find that prototype and to see how the event was entered.

 

Kudos for giving it a try.  I'll get back to you.
