It won't work the way you are doing it now. You are using an ls
command to dynamically create the list of files to check in your
client-local, so when that file is missing, the ls command doesn't
output it as a filename to check, so the test drops off when that file
dissappears,<br>
<br>
Since the files are dynamic, I assume created every day, you are going
to have to figure out a way to tell if one of them goes away. Maybe
you could have a cron job that runs every morning, and does an ls of
the files and saves the output somewhere like
/var/tmp/todays_files.txt, and then in your client-local you could do
something like:<br>
<br>
[hostname]<br>
file:`head -1 /var/tmp/todays_files.txt|tail -1`<br>
file:`head -2 /var/tmp/todays_files.txt|tail -1`<br>
file:`head -3 /var/tmp/todays_files.txt|tail -1`<br>
...<br>
<br>
That would add a file entry for every line of todays_files.txt. So if
one of the files got deleted, it would still be referenced in
todays_files.txt, and thus continue to be monitored (including
notification that it was no longer there).<br>
<br>
That is a frightful way to do it, but I can't think of anything better
at the moment :) Dealing with randomly generated filenames is a pain.<br>

of my problem of why the file
