Our solution is similar to afedden, and for the same concerns (no non-f5-admin owner with anything but readonly). Monitors for web servers here send GET /status.html, expect 'Service is up', and disable string 'Service is down'.

 

This gives service owners autonomy they really enjoy. They change their own html document to return 'maintenance' or something similar to gracefully remove a pool node, 'Service is down' to match the receive string, and 'Service is disabled' to match the disable string.

 

The disable string in practice never benefits the service owner because it takes much to long for connections to fade away.
