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 using two different replication
modes ( fanout, failover ).
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.
Failover mode will forward all the syslog messages to the primary rsyslog server and
in case of failure will use the secondary rsyslog server.
In you want to choose to failover mode, this will require that your current
rsyslog server is binded to TCP port 514.
This is a subordinate charm, which means it requires to have a service to hook in. On this
example we are going to deploy mysql
juju deploy mysql
Then you must deploy this charm
juju deploy rsyslog-forwarder-ha
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
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"
