I am trying to understand how log rotation and other regular tasks work. I thought I understood cron and didn't need anacron but find it's installed anyway now and it's emailing me daily, weekly & monthly reports and I've worked out that it's being called by cron from /etc/crontab ... all well and good and I think I can see . Also my direct entries into root's crontab are working fine.
However, I don't really understand what's rotating my mail logs. I can see that some things are rotated by logrotate which is called daily by cron but can rotate at whatever pace is set for the log in /etc/logrotate.conf (e.g. for /var/log/wtmp) or in a file for each package in /etc/logrotate.d Trouble is that I can't see that mail logs are rotated by that (I run postfix logging to /var/log/mail.log etc.) I think they would be rotated by cron.weekly savelog using sysklogd-listfiles to give a list of logs to rotate (I'm guessing this bit). However, cron.weekly is Emailing me this: /etc/cron.weekly/sysklogd: /etc/cron.weekly/sysklogd: syslogd-listfiles: command not found /etc/cron.weekly/sysklogd: syslogd-listfiles: command not found and I think that may be because I'm running syslog-ng not sysklogd (syslog-ng is the only "sys" in ps aux output).... but my mail logs are getting rotated every Sunday at a time varying from 07.37 to 08.18 to judge from the timestamps on the files. I'd really like to understand how this is happening, not least because I want to stop them being compressed and set up pflogsumm to run immediately after the rotation on the last week's log.
