F5 Health Monitor, Remote Server Maintenance

Is this a web app? If so, take a look at the "receive disable string" option of your current health monitor. If you have access to manipulate the health monitor response from the pool members, I think it would be cleaner and not rely on a separate management server. If you use a separate management server and that server has an unexpected outage, not good, especially when you don't have admin access the the F5 environment.
