OK, so, something like this;

 

when HTTP_RESPONSE { 
 if { [HTTP::status] >= 400 } { 
 log local0. "[LB::server addr] in Pool:[LB::server pool] returned HTTP status: [HTTP::status]" }
}

 

Alternatively, if you meant only log this for a specific server;

 

when HTTP_RESPONSE { 
 if { ([LB::server addr] equals 10.20.10.100) && ([HTTP::status] >= 400) } { 
 log local0. “[LB:server addr] in Pool:[LB::server pool] returned HTTP status: [HTTP::status]” }
}
