The "check_load" nagios check should not be hardcoded to some arbitrary
value. The thresholds should rather be adjusted in function of how many
CPUs are present in the server.
The factors were chosen by prior experience but could be adjusted if
needed.
Factors for warning thresholds (where N is the nb of cpus):
* 1min : 5 * N
* 5mins : 4 * N
* 15mins : 3 * N
Factors for critical thresholds:
* 1min : 10 * N
* 5mins : 9 * N
* 15mins : 8 * N

The default nsca.cfg is currently using the "non-normal" port for nsca.
Let's import a freshly installed nsca.cfg file with default values.

The current code tries to get the content of those two files in a bunch
of places and defines a fallback to a generic file in the module's
files/configs directory.
The problem is that there is no such generic config file present.
Link to Debian's config files as a generic version of those
configuration files.
This bug was found by taggart.

Koumbit is using an IRC bot that Micah provided. It is a pair of perl
scripts that send Nagios notifications as messages in an IRC channel.
Add a class to make installing this IRC bot easy. It also defines
commands 'notify-by-irc' and 'host-notify-by-irc' that can be used with
checks to send notifications via the bot.

Currently, the nagios module purges all files under the Nagios
configuration directory. This has the unwanted effect of removing files
that are added by default by the .deb packages, thus making the Nagios
interface non functional under apache.
To fix the situation, make nagios::apache under Debian manage the apache
config file and link to it in apache's conf.d directory, in the same
manner as the Debian packages do.

check_dns had some problems with down nameservers. This one properly
checks the right nameserver.

. add an additional nagios::defaults::plugins class that is included in the nagios::defaults, this can be used to install other nagios plugins that aren't distributed in the nagios-plugins package
. use the nagios::defaults::plugins to setup the check_mysql_health plugin
. add a check_mysql_health command to defaults/commands.pp in the section for commands for services defined by other modules
. change the nagios::service::mysql to use the more advanced check_mysql_health plugin, instead of the basic check_mysql plugin

Debian nagios.cfg file without this enabled, the plugins which are
installed by the nagios-plugins and nagios-plugins-basic packages will
not be enabled, causing undefined service check command errors in the
nagios pre-flight check. Because the nagios-plugins-basic package is
installed as a Depends for the nagios3 package, and nagios-plugins is
usually brought in, due to nagios3 having a Recommends on it, it a
good idea to have this plugin location enabled.
