logs are not logrotated

I've seen big log files in some of my long running deployments as well; Marking 'Triaged' and 'Medium' and raising a task for juju-core as well.

We clearly should rotate logs, but the urgency has gone down since we made some changes to what we log in the course of initial juju-core scale testing.

$ du -hs /var/log/juju/
6.9G /var/log/juju/

System installed on 2014-06-02.

ubuntu@juju-prod-XX-YYY-machine-0:/var/log/juju$ ls -la
total 19790064
drwxr-xr-x 2 syslog adm 4096 Oct 2 07:33 .
drwxr-xr-x 11 root root 4096 Oct 2 06:38 ..

Err, it's .1 because I manually rotated them

As an interim solution:

juju deploy cs:~chris-gondolin/trusty/logrotate
juju set logrotate='logfiles={"juju":{"path":"/var/log/juju/*.log"}}'

Thanks for the Can you provide the contents of the logrotate.conf that Juju generates? There was a bug that prevents Juju from properly rotating log files that was fixed in master (https://github.com/juju/juju/commit/d4328ef1d825679d67aee76f2e6709ce4faddaf6) and I want to make sure that this isn't the same issue.

Turns out that Juju 2 now rotates logs by size, 300MB, internally (and tar.gz's them). we can close this bug.
