Bug Description

With the local provider, I am unable to send syslog messages to the rsyslog service:

juju deploy ubuntu
juju deploy rsyslog
juju deploy rsyslog-forwarder
juju add-relation ubuntu rsyslog-forwarder
juju add-relation rsyslog-forwarder:syslog rsyslog:aggregator

The rsyslog unit is happily logging local syslog messages:

juju run --unit rsyslog/0 'logger -p local0.error This is a local message'
juju run --unit rsyslog/0 'sudo tail -1 /var/log/syslog'

However, sending messages from the remote unit does nothing:

juju run --unit ubuntu/0 'logger -p local0.error This is a remote message'
juju run --unit rsyslog/0 'sudo tail -1 /var/log/syslog'

I also get this behavior on Canonistack.

There are several problems with the rsyslog and rsyslog-forwarder charms:

- The rsyslog-forwarder is attempting to send to rsyslog via TCP to port 10514
- The rsyslog aggregator is listening for UDP messages on port 514
- TCP would be nice, but rsyslogd is crashing when a TCP listener is configured (precise LXC container). This is possibly why it was removed from the last commit to the rsyslog charm.

For now, I think rsyslog is fine and the forwarder needs to be updated to talk UDP to port 514.

OK, i fixed this by forwarding all the forwarder rsyslog messages to UDP port 514.
