A script to monitor that functions are working properly

[krambriw]

Hello,

I have played a bit with creating a script for a special purpose using the email sending sample provided by Bartman (thanks!) and it works as follows:

- The script starts a MainTask that then schedules itself and performs certain tasks as long as all conditions are fulfilled
- The script also starts a thread that schedules a LiveCheck monitoring function

As long as the MainTask is running, the LiveCheck is OK and nothing else except logging really happens. However, when the MainTask stops, the LiveCheck sends an email with an error report.

Could you please give me a feedback on the script below if this should be done differently or if you have any ideas to make it better/simpler/more professional?

I have attached an xml-file for the simple eg project so that you can run it easily. I have commented out the actual email sending...

First start the "LiveCheckWithThread" script and you should see activities in the log.

Then stop the MainTask by starting the "Stop" script (it sets a eg.globals that is used as a condition flag to stop it)

Best regards, Walter
