Hi Larry. Thanks for the reply.
There should always be files in the directories. The dba keeps 7 days of backups and deletes anything > 8 days old.
So, here's an update to see if anyone has other suggestions. It's still not working. Details on current settings for client-local.cfg and analysis.cfg are below:
Any further help or alertnative method appreciated…

client-local.cfg for mysqlserver01:
[MYSQLSERVER01]
# dir:`find /Volumes/MySQL_Backups/ -name '*.sql' -mtime 0 2>/dev/null`
# file:/Volumes/MySQL_Backups/mysql_backup_20121004.sql
file:`find /Volumes/MySQL_Backups/ -name '*.sql' 2>/dev/null | sort -r | head -1`
This returns a file with the latest timestamp -
Fri Oct 5 12:59:57 CDT 2012 - Files ok
[green] /Volumes/MySQL_Backups/mysql_backup_20121005.sql<http://srmxymon.ambrosi.com/xymon-cgi/svcstatus.sh?CLIENT=MYSQLSERVER01&SECTION=file:/Volumes/MySQL_Backups/mysql_backup_20121005.sql>
Clicking the link above gives this:

If there will always be files in that directory you might want to consider getting rid of the -mtime argument to your find command. That way you will always get a file returned and then your mtime test in analysis.cfg will catch that the returned file, which should be the newest one in the directory thanks to the sort, is too old.
Thanks,

Thanks Ryan. Do you have any suggestions on how to get an alert if the
file doesn't exist ? It only gives me "no files checked" when the file
isn't there. That's okay if I can get that translated into an email that
informs someone that no file was created.
Does that make sense, or is my logic flawed ?
