hi all,

Trying to get file monitoring to work. Works find with fixed filenames 
but I need to match a pattern in a directory and find the oldest file. 
If more than say 7200 sec old in mtime then generate an alert.

in client-local.cfg I have

file:`ls -t /ftp/input/* | tail -1`

which produces the oldest file name on the web page.

I have the following in hobbit-clients.cfg

   FILE %/ftp/input/*.gz RED mtime<7200

but I get no alarms.

Any ideas ?

For wildcard, you want '.*' to represent any character instead of '*'
alone.  I have a handful of this kind of FILE checks.

another thing I do is use /bin/ls instead of 'ls', so the file name
generated by the backticks won't contain any termcap escape characters or
alike.

Do you mean like this ?

FILE %/ftp/input/.*.gz RED mtime<7200 or

FILE %/ftp/input/.* RED mtime<7200

both are ok,since .* is not greedy as in PERL's. The former is preferred
since it provides more exact match.

to my surprise, * actually works on my Hobbit-4.2rc1-20060712 server.

what's your test condition?  You want it to alert when your oldest file is
less than 2-hour old ?   More commonly, people want to test if their oldest
file is older than 2-hour old (mtime >7200 instead of mtime < 7200).

To further troubleshoot: on your client, check the
logfetch.ClientNameHere.cfg under ~hobbit/client/tmp/. Also check
msg.ClientNameHere.txt therein to see whether it has a
[file:/ftp/input/oldestFileName.gz]
section.

I left it with the .*.gz to look acuratly for the files I want to 
monitor - and ys you are right I need to switch the contition for mtime 
round.

The tip og using the full file path made it work.
