=========
NagiosGen
=========

This page describes the installation and use of the [http://trac.mcs.anl.gov/projects/bcfg2/browser/trunk/bcfg2/src/lib/Server/Plugins/NagiosGen.py NagiosGen] plugin. 

Update /etc/bcfg2.conf, adding NagiosGen to plugins::

    plugins = SSHbase,Cfg,Pkgmgr,Rules,TCheetah,TWbase,NagiosGen

Create the NagiosGen directory::

    $ mkdir /var/lib/bcfg2/NagiosGen

Create default host, and group specs in:

* /var/lib/bcfg2/NagiosGen/default-host.cfg::

    define host{
            name                            default
            check_command                   check-host-alive
            check_interval                  5
            check_period                    24x7
            contact_groups                  admins
            event_handler_enabled           1

            max_check_attempts              10
            notification_interval           0
            notification_options            d,u,r
            notification_period             workhours
            notifications_enabled           1
            process_perf_data               0

            retry_interval                  1
            }

* /var/lib/bcfg2/NagiosGen/default-group.cfg::

    define service{
            name                            default-service
            active_checks_enabled           1

            notification_period             workhours
            }

Create group configuration files (Named identical to Bcfg2 groups) and
add services, and commands specific to the hostgroup (Bcfg2 group) in

* /var/lib/bcfg2/NagiosGen/base-group.cfg::

    define hostgroup{
            hostgroup_name  base
            alias           base
            notes           Notes
    }

    define service{
            service_description             NTP
            check_command                   check_ntp!
            use                             default-service
            hostgroup_name                  base
            }

    define command{
            command_name    check_ssh
            command_line    $USER1$/check_ssh $ARG1$ $HOSTADDRESS$
            }

    define service{
            service_description             SSH
            check_command                   check_ssh!
            use                             default-service
            hostgroup_name                  base
            }

* /var/lib/bcfg2/NagiosGen/web-server-group.cfg::

    define hostgroup{
            hostgroup_name  web-server
            alias           Port 80 Web Servers
            notes           UC/ANL Teragrid Web Servers Running on Port 80
    }

    define command{
            command_name    check_http_80
            command_line    $USER1$/check_http $HOSTADDRESS$
            }

    define service{
            service_description             HTTP:80
            check_command                   check_http_80!
            use                             default-service
            hostgroup_name                  web-server
            }

Create a nagios bcfg2 bundle /var/lib/bcfg2/Bundler/nagios.xml

.. code-block:: xml

    <Bundle name='nagios' version='2.0'>
      <ConfigFile name='/etc/nagiosgen.status'/>
      <Group name='rh'>
        <Group name='nagios-server'>
          <ConfigFile name='/etc/nagios/nagiosgen.cfg'/>
          <Package name='libtool-libs'/>
          <Package name='nagios'/>
          <Package name='nagios-www'/>
          <Service name='nagios'/>
        </Group>
      </Group>
      <Group name='debian-lenny'>
        <Group name='nagios-server'>
          <ConfigFile name='/etc/nagios3/nagiosgen.cfg'
                      altsrc='/etc/nagios/nagiosgen.cfg'/>
          <Package name='nagios3'/>
          <Package name='nagios3-common'/>
          <Package name='nagios3-doc'/>
          <Package name='nagios-images'/>
          <Service name='nagios3'/>
        </Group>
      </Group>
    </Bundle>

Assign clients to nagios groups in
/var/lib/bcfg2/Metadata/groups.xml

.. code-block:: xml

    <Group name='nagios'>
      <Bundle name='nagios'/>
    </Group>

    <Group name='nagios-server'>
      <Bundle name='nagios'/>
    </Group>

Update nagios configuration file to use nagiosgen.cfg::

    cfg_file=/etc/nagios/nagiosgen.cfg

Note that some of these files are built on demand, each time a client in group "nagios-server" checks in with the bcfg2 server. Local nagios instances can be configured to use the !NagiosGen directory in the bcfg2 repository directly.
