I agree - we can provide some interface which can smoothly integrate 
monit with external check scripts.

The script should return to monit (for example):
- the status (error level)
- detailed description of the situation (message)

The script should probably not perform the action itself - this should 
be monit responsibility. Monit can map the error level (status) to the 
appropriate action and call the methods (such as alert, stop, restart, 
unmonitor, etc.)

Monit can encapsulate the script:

- set the timelimit on script execution (in the case that the script 
will not return in some time limit, monit can perform the actions 
related to unresponsive fault monitor (for example send alert, etc.)

- make sure that there is just one instance running
