rsyslog forwarder ha #2

Supports: trusty


Uses rsyslogs facilities to forward to multiple remote syslog servers.


This Charm provides support for adding a rsyslog forwarder listener to any service in addition this charm allows to have multiple rsyslog aggregators servers offering currently 2 replication modes ( fanout, failover ).

Usage method

This is a subordinate charm, which means it requires to have a service to hook in.

    juju deploy mysql

Once your service is running, you can relate this charm:

    juju add-relation rsyslog-forwarder-ha mysql

Then you can deploy your rsyslog aggregators servers:

    juju deploy rsyslog primary
    juju deploy rsyslog secondary

Once your rsyslog aggregators are ready, you can relate them with your forwarder.

    juju add-relation rsyslog-forwarder-ha primary
    juju add-relation rsyslog-forwarder-ha secondary

By default the 'fanout' replication mode is going to be used, which means that all the syslog messages will be forwarder to any aggregator server using UDP port 514.

In you want to choose to failover mode, this will require that your current rsyslog servers is binded to TCP port 514.

Once you have your rsyslog ports opened. You can change the replication-mode variable on your rsyslog-forwarder-ha charm.

    juju set rsyslog-forwarder-ha replication-mode="failover"
