iRUle to check current pool member and show if its up.

I believe I see where your problem is. I think the problem stems for the actual load balancing selection that is occurring. taking that into account and doing some tweaking I think this might work nicely for you

 

 

 
 when HTTP_REQUEST { 
 if {[HTTP::uri] eq "/status" } { 
 scan [LB::select] %s%s%s%s%d command current_pool command2 current_member current_port  
 eval [LB::select] 
 set response "$current_pool Pool Status - [clock format [clock seconds]]" 
 if { [active_members $current_pool] < 1 } { 
 append response "POOL NAME:$current_pool
 CURRENT MEMBER:$current_member:$current_port
 STATUS: DOWN 
" 
 } else { 
 append response "POOL NAME:$current_pool
 CURRENT MEMBER:$current_member:$current_port
 STATUS: UP 
" 
 } 
 } 
 HTTP::respond 200 content $response "Content-Type" "text/html" 
 } 
 

 

 

Keep in mind that the code is forcing the LB evaluation early so this may have impact on load balancing after the code is run.
