iControl / iRules or Health Monitors?
Hello again!
Since posting the last question about the iControl rules of engagement, I've been looking at our existing solution (very backend monitoring heavy) and have determined that in our environment it will not scale very well.
To this end, I'm trying to work out if there is any way of setting a dependency on the minimum number of active pool members. I've seen that dependencies can be created on 3DNS, our service requires three wide ip's which are all dependant on each other being available, if any are down, a regional failover occurs (at 3DNS level).
I'm trying to work out the best method for applying the following logic on BigIP:
Pool A ( 6 members )
If Pool A has less than 4 session state active members then mark pool down.
Any comments / advice warmly received as ever!!
