[Xymon] File monitoring with `date` in filename

Hi Mark,

thanks, but this doesn't work either. I assume the problem is that the backticks are evaluated, but the "$(date)" isn't as that is done by sh and sh doesn't know $(variable). So what we need is some thing like one backtick expansion after the other. or a way to let ksh do the job. But I don't know if there is way to achieve that.

The workaround is ok for the moment. If the log is missing it wouldn't be very serious as we are checking for MTIME<600 (last access more then 10 minutes ago). So xymon will get red in case todays file is missing as it is older than that, kind regards Rolf

Wonder if you need to preface the operation with an eval to get the date command to operate first -- don't know if this will work with Xymon.

FILE eval find /home/mypath/log/update_out_$(date +%Y%m%d).txt MTIME<red

The other thing I would be a little leery of, is having any expression calculation in the filepath variable in the find command -- some older Unix flavors may get upset over this syntax. Calculations/regex tend to be better supported with the --name attribute. Ditto with presumed output versus need to use "-print " in older find commands. If you don't need to support older Unix flavors, then ignore all of this.

FILE eval find /home/mypath/log --name "update_out_$(date +%Y%m%d).txt" --print MTIME<red

Above would need more work though as by itself it will keep hunting down the log directory tree for possibly other files.

The thing I don't particular care for with ls --tr /home/mypath/log/update_put_*.txt| tail -1 is what happens if the current day's file is missing? Then you are parsing yesterday's or the last log file. No complaints if the wrong file is being operated on. Would ~assume you want some kind of alert if the today's log file is missing....

Thanks Deepak,

unfortunately that won't help as I need the file with the present date in its name. I did now: ls -tr /home/mypath/log/update_out_*.txt|tail -1 This workaround helped. But I'm still curious if there is a solution for first expanding the date and second the whole expression find /home/mypath/log/update_out_$(date +%Y%m%d).txt (sorry, I dropped the find in my first posting)

kind regards Rolf

Looks like your analysis.cfg entry is wrong.Try this.

FILE /home/mypath/log/update_out_[0-9]*-[0-9]*-[0-9]*\.txt MTIME<600 red

Dear xymon users,

I got stuck while trying to monitor a file which should be updated regularly and which has got a timestamp in its name. "files" on the server remains clear, no data . Could someone tell me what is wrong with these settings or what have i forgotten?

On the server we have in analysis.cfg HOST=myserver FILE /home/mypath/log/update_out_$(date +%Y%m%d).txt MTIME<600 red

in client-local.cfg: [myserver] file:find /mypath/log/update_out_$(date +%Y%m%d).txt

I see an entry for this file on the client in tmp logfetch.myserver.cfg file:find /mypath/log/update_out_$(date +%Y%m%d).txt

but there is nothing for this file in msg.myserver.txt

File exists and is readable: find /home/mypath/log/update_out_$(date +%Y%m%d).txt -exec ls -l {} \; -rw-rw-r-- 1 ... 2467070 Sep 26 08:43 /home/mypath/log/update_out_20130926.txt

In xymonclient.log I see an entry sh: syntax error at line 1: (' unexpected but I don't know if it is related to the file problem or to anything else. I know that sh can't deal with $(xy), I tried as well FILE /home/mypath/log/update_out_date +%Y%m%d`.txt MTIME<600 red but in vain.

Any help appreciated, kind regards Rolf
