Hi Peter,

 

 

The simplest option might be to build a status page on the application which displays UP if the count of sessions or jobs that the server is currently processing is lower than the threshold it can handle. You could then configure an HTTP monitor to check the page for the string "UP". If the server doesn't show UP, it would be marked down by the pool.

 

 

Else, you could potentially use an iRule to count the number of jobs which have been sent to each server, but it would be much more complicated compared with the first option. If you do want to explore the iRule route, can you explain how you could determine when a job has been started and completed based on the request and/or responses sent to the VIP?
