I did see you writeup on Cacti some months ago. Our Chief Network Engineer has a Cacti effort underway and has one developer working on integrating Cacti into the NOC. Their primary focus is to status 1000+ Cisco devices spread across the network but I have added their server to the F5 SNMP access list. I pointed the developer to your writeup in hopes of helping her get the BigIP into a template.
I will give the Cacti solution another look. I will still have to see the iRule solution through the end now that I have ventured down that path.
Thanks to both of you for the quick feedback!!!
