Cron syslog issue

    I have written a custom cron. This cron executes a rake task every 5 minutes. I also log the trace of this execution in a file locally on my server. The whole process seems to execute seamlessly every 5 minutes, but then it seems to log it in /var/log/syslog. I investigated on the syslog and found that system's critical errors, and other cron issues are logged in syslog. Has anybody faced this kind of an issue ?

    Everything is logged in syslog

    it's defined in the config file /etc/rsyslog.conf
    Code:
    *.*;auth,authpriv.none		-/var/log/syslog
    If you want cron log to go somewhere else, uncomment the line
    Code:
    #cron.*				/var/log/cron.log
    and all cronlog entries will go there (they will also still go to syslog though.

    Syslog.conf

    But in my etc/syslog.conf, Everything is referenced as /mnt/log/syslog and not /var/log/syslog .

    Is this the same for you also.. I Have logged in as root.

    Ah well, that depends on what the admin of the server set-up.

    default it's /var/log/* .. but maybe if you run in a openvz container, vps, or smth .. those folders could be different (weird, but ok) ..

    If all your log files are in /mnt/log/*

    then set a line: cron.* -/mnt/log/cron.log

    in your rsyslog.conf and restart rsyslogd

    syslog issue

    Thanks for the quick reply..

    But, I have these logs stored both in

    /var/log/syslog and /mnt/log/syslog

    is this possible. My configuration seems to store only in /mnt/log/syslog

    it might help if you post the content of rsyslog.conf :)

    Code:
    sed -i 's/#cron\./cron\./' /etc/rsyslog.conf
    /etc/init.d/rsyslog restart
    all cron related stuff will go into /mnt/log/cron.log now

    I guess that /mnt/log and/or /var/log is a symlink to one another

    show me:
    Code:
    ls -al /var
    ls -al /mnt
     
: cron, rails
