Ok. I don't know why but today I decided to just remove the files and the monitor and then re-added them just like I did the first time and now it's working. Unfortunately I can't seem to see what the result of the test really is. I tried to redirect the output to a different file but it creates the file with nothing in it. I set DEBUG=0 and also DEBUG=1 and neither setting produces any additional output.
I don't know why it didn't work from the beginning because it's actually configured identical to my original attempt.
