Problem this snippet solves:
There currently isn't a way to directly access which pools are referenced in iRules and which iRules reference pools. This sample solves that by pulling down all pools and rules and searches the content of the rules for a reference of each pool. It then presents two tables: The first shows all the rules with a listing of the pools that are referenced in them. The second shows all the pools with a listing of all rules they are referenced in.
