NimbostratusiRule to monitor dependant servers
Hi iRule noob ... Is it possible to construct a cunning iRule which monitors servers that are not in a pool, but the servers IN the pool are dependent on these downstream servers [I think Oracle db] ...

CirrusUsing iRule SIDEBAND you can "interact" with external server/service (check availability in your scenario):

But in my opinion the best choice is to create an external monitor that will do monitoring of your external server and apply to pool members.

You don't have to check external server availability for every connections you receive on VS, so an external monitor will be a good solution.
