Rsyslog is a multi-threaded implementation of syslogd (a system utility providing support for message logging), with features that include:
- reliable syslog over TCP, SSL/TLS and RELP
- on-demand disk buffering
- email alerting
- writing to MySQL or PostgreSQL databases (via separate output plugins)
- permitted sender lists
- filtering on any part of the syslog message
- on-the-wire message compression
- fine-grained output format control
- failover to backup destinations
- enterprise-class encrypted syslog relaying
This is a simple rsyslogd logging server. It is most interesting when paired with the rsyslog-forwarder subordinate charm.

This charm provides support for setting up a simple rsyslogd logging server.
On this example we are going to deploy mysql
juju deploy mysql
Then you must deploy this charm
juju deploy rsyslog primary-rsyslog
Then you can deploy a rsyslog-forwarder-ha charm, which will forward all the syslog messages from a specific service to this rsyslog server.
juju deploy rsyslog-forwarder-ha
Then relate both services
juju add-relation rsyslog-forwarder-ha mysql
Then you can deploy your rsyslog aggregators servers:
juju deploy rsyslog primary
Once your rsyslog aggregators are ready, you can relate them with your forwarder.
juju add-relation rsyslog-forwarder-ha primary-rsyslog
Once you have your rsyslog ports opened. You can change try this charm by running
juju ssh mysql/0
Then create a logger entry
mysql/0$ logger "testing"
Then see if the entry is being forwarded correctly:
juju ssh primary-rsyslog/0 primary-rsyslog/0$ grep testing /var/log/syslog
