LTM - iRule to check monitor status and route traffic accordingly.

The server should only be configured on 443 in the default pool. The default pool is assigned two monitors - HTTPS and TCP check to see if its listening on 8300. If either of 443 or 8300 monitor is down send traffic on port 8200. If both 443 and 8300 is down then mark pool offline (use default pool). So, i created the pool with the server on port 443. Assigned it both monitors. Set availability to 'ALL' which take down the pool and then through iRule I can route it to 8200. However, what i am not able to achieve is 'when both monitors are down, use the default pool'.
