Rsyslog

General

This charm provides support for setting up a simple rsyslogd logging server.

Usage method

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

Setting the protocol

By default rsyslog charms uses the UDP protocol, but also RELP or tcp can be used.

juju set rsyslog protocol="relp"
juju set rsyslog-forwarder-ha protocol="relp"

Forwarding logs to a system outside of the Juju environment

For forwarding within the Juju environment use the subordinate charm rsyslog-forwarder-ha but to forward the aggregated logs outside of the Juju environment you set the forward_* options.

juju set rsyslog forward_host="elk.my.domain"
juju set rsyslog forward_protocol="tcp"
juju set rsyslog forward_port="514"
