 * '''Launchpad Entry''': UbuntuSpec:server-o-improve-monitoring
 * '''Created''': 2011-05-20
 * '''Contributors''': ChuckShort
 * '''Packages affected''': nagios, mcollective, collectd

== Summary ==

== Release Note ==

Oneiric includes improved monitoring support integrated into Orchestra.

== Rationale ==

If an Ubuntu Systems Administrator deploys a large number of Ubuntu Servers, they want to manage their monitoring effectively by automating the monitor setup.

== User stories ==

* Corey is a systems administrator who deployed a 12 node Ubuntu Cloud and wants to know if the Nova API is not responding to requests and wants to be notified by SMS.
* Nigel is a systems administrator who wants to know how much CPU usage a particular instance is using over time. Nigel will use the collectd-nagios plugin to monitor the usuage of the instance. 

== Assumptions ==

== Design ==

You can have subsections that better describe specific parts of the issue.

== Implementation ==

== Nagios ==

The central component of the monitoring part of Orchestra is nagios. Nagios will be configured to trigger a restart everytime a new machine is added by orchestra. 

== Mcollective ==

To query the machines that are to be monitored is through an mcollective plugin. The plugin will query the server that is to be monitored and will write a nagios configuration file for the server.

== Collectd ==

Collectd is a tool to collect information. There are two pieces to this part of implementation, make nagios-collectd work with mcollective and provide a small cgi program that will display the graphs to show the history of an interface.

== BoF agenda and discussion ==

{{{
    Default right now is nagios, might change eventually.
