After I installed nginx, its logs have been rotating weekly as per a weekly cron job on Sunday 00:00
However this week the logs failed to rotate, and I can't figure out why.
The only thing I can think that would have affected it is I did an apt-get upgrade. This went smoothly, with only one config file needing manual merging.
I can't find any logs for logrotate itself. It seems like I would expect to see something in /var/syslog for the logrotate cron job, but there's nothing there (ever).
Second, logrotate seems to be properly configured for nginx. There is an nginx config file that looks good in logrotate.d
logrotate cron job is also still in /etc/cron.daily
Thanks for any help - looking for the reason that this could have worked before but suddenly stopped, or for where to look for any extra logging output from cron or logrotate itself.
