Notifications via External Monitor

Can you clarify what you mean by "will not work" when run as an EAV ? Do you mean that the semaphore file isn't deleted, or is it that it isn't created and you get continuous emails, or something else ? Also, rather than running curl a second time if the monitor fails, I would grab the output in the first curl, and store that in a variable to be written to the .html file on failure, just in case the pool member's output has changed between the first and second instance or curl.
