Hey Alex,

After following this advice, I could easily see that this happens due to disk
space running out on my server,
it seems that the logs has filled over 100GB of log data, since I made a
configuration mistake (I think?) by setting this:
> quote_type
> logfile_rotate 0

If I remember and read correctly, this means that the rotation of the files is
disabled and they will just keeping increasing
in size if left unchecked.
I have now gone ahead and changed all the configuration file to this setting:
> quote_type
> logfile_rotate 1
>
So now it should rotate once daily, and on the next rotation it should be
deleted, and this is all handled by logrotate on Debian-based machines?
This is my / cat /etc/logrotate.d/squid:
➜ / cat /etc/logrotate.d/squid
#
# Logrotate fragment for squid.
#
/var/log/squid/*.log {
daily
compress
delaycompress
rotate 2
missingok
nocreate
sharedscripts
prerotate
test ! -x /usr/sbin/sarg-reports || /usr/sbin/sarg-reports daily
endscript
postrotate
test ! -e /var/run/squid.pid || test ! -x /usr/sbin/squid || /usr/sbin/squid
-k rotate
endscript
}
Is there a way for me to set it so it just get deleted every 24 or 12 hours
without the archive first?
Thanks,
Roee
