Re: [Condor-users] Truncate, rotate or archive history file?

One of my friends advise me this:

Create a file, say  condorhistory in /etc/logrotate.d/


/path/to/condor/spool/history {
    rotate 52
    olddir /home/condor/spool/history/rotated

If you want to force a rotation now rather than waiting 1 week.

Run: /etc/cron.daily/logrotate

and then edit: /var/lib/logrotate.status

and change the date for this file to say the year 2004

Then run: /etc/cron.daily/logrotate

again or just wait one week. Hope that helps.

Our HISTORY files on each of our Condor nodes is getting large. Is
there some way to safely truncate and archive this file without
shutting down a daemon, or configure it to be done automatically?

You can just "mv" it to a new name, a new file will be created.

What I do is keep a hard link to "history" named "history.YYYYMM".
At the start of the month I can simply delete "history".  In this case
I also create a new "history" myself so I can make a new hard link.

I do this automatically with a cron job:

0 0 1 * * cd /exports/condor/spool && rm history && touch history && ln history $(date +history.\%Y\%m)
