Monitor and pull a node

Howdy,

 

I've looked this forum and I can't seem to find something I need???

 

 

I am looking to monitor the CPU of a web server (which is being load balanced in a pool) and when the CPU gets to a certain point pull the web server out of the pool? I see where people are using SNMP and WMI for some of this but for whatever reason those monitors according to the manual are for "weighted" load balancing? I want to use a non specific load balance (round robin) and just have the f5 pull the server when CPU gets to a certain point. Anyone got any ideas how to solve this puzzle?

 

 

 

Thanks

    You could build an external monitor which only returns up if the script finds the server CPU usage below a defined threshold.

     

     

    You can find example external monitors in the Codeshare:
