Munin is a system monitoring, network monitoring and infrastructure monitoring software application. Munin offers monitoring and alerting services for servers, switches, applications, and services. It alerts the users when things go wrong and alerts them a second time when the problem has been resolved.
Munin is a highly flexible and powerful solution used to create graphs of virtually everything imaginable throughout your network, while still maintaining an ease of installation and configuration. This package contains the grapher/gatherer. You will only need one use to create graphs and HTML pages, suitable for viewing with your graphical web browser of choice. It is also able to alert you if any value is outside of a preset boundary, useful if you want to be alerted if a filesystem is about to grow full, for instance. You can do this by making Munin run an arbitrary command when you need to be alert it, or make use of the intrinsic Nagios support. Munin is written in Perl, and relies heavily on Tobi Oetiker's excellent RRDtool.

You can deploy the munin service with the following command:
juju deploy munin
You can then browse to http://ip-address/munin to view the service.
The munin charm can be related to monitor several exisiting charms. The munin interface is present on haproxy, mediawiki, memcached, and mysql charms.
You can add a relation to those charms by:
juju add-relation munin:munin mysql:munin juju add-relation munin:munin haproxy:munin juju add-relation munin:munin memcached:munin
There are no configuration options for munin at this time. Just deploy the service and you are all set!
