You can add logging statements to your external monitor to view the variable output. /var/log/ltm is a good target.
Once I know the variables, I play with the script from the shell until it behaves like I expect.
Make sure you have handling to gracefully exit the process included in the script. These monitors fire off at the interval you specify, usually seconds, and they can stack up quite quickly and cause memory contention issues.
If your external monitor was going to use curl, for example, the variables you create in the external monitor definition would become the arguments for curl.
-u $username -p $password, etc.
