WLS: Advanced Monitoring with F5 Questions

We have created our own monitor addition to the application that F5 monitor uses to identify problems - monitores cpu load, states of wls, running states etc. So if the WLS is rejecting requests to the monitoring applet or the reported states are not as described, the node state is set down. When the monitor is down, the irule knows which was the session replica server and forwarded next requests to the second server. So if the node is set down, then only active connections are allowed, when some connections are released and wls is not overloaded anymore, the f5 monitor request sets the node to the active state.
