I must confess ... this mission got me to add a PerfStack widget to my Orion NOC! Generally I use it to check the stats on my VM's. This time, I created a PerfStack Widget of Core Switches and a PerStack Widget of my PaloAlto Firewalls... very cools stuff! Thanks @KMSigma.SWI for the quick video!!! Have had a fun time with this mission.. thought provoking ... not going to the Cloud any time soon, but I did feed off the comments from users and hope to be ready to monitor when the time comes!
