Hi Trent,

I have tried copying your configuration and your notification script 
verbatim, but unfortunately it didn't work, the logger executable didn't 
write anything and I could not even determine if it was called at all.

I'm probably doing something very wrong but I cannot figure it out. For 
the moment I'll go back to a simple shell script for disk space 
notifications.

Thank you very much for your help.
