Hello Brijesh.

 

Pool monitoring works separately from the regular traffic. Actually, regular traffic is managed by TMM deamon and monitoring uses a different one (bigd).

  • bigd is control-plane
  • tmm is data-plane

 

Having said this, you could modify some big-ip configuration using iRules+iCalls but I don't recommend you do that. Your best chance is to configure a custom monitor instead.
