Server Monitor Flapping

I was wondering if there was something one could do to remove a member out of a pool after a repeated up/down state in a certain period of time?       Thanks!

Here are a few related examples:

 

 

 
 when HTTP_RESPONSE { 
     Check if response code is a 503 
    if { [HTTP::status] == 503 } { 
  
        Mark current server down 
       LB::down 
    } 
 }

 

 

 
 when LB_FAILED { 
     Mark current server down 
    LB::down 
 }

 

 

For info on the LB_FAILED event, you can check the wiki page:
