[Puppet Users] Nagios Module and use of the @@ and <<||>> notation

Greetings, 

I am working on getting Nagios implemented with Puppet so that when I add a
node to Puppet a Nagios configuration file is generated.

I can get nagios installed and configured on the server and the client with
no problems.  Yet getting the client configuration file on to the server is
not happening. I did have it working at one point in time yet It seems that
I cannot get back to that configuration.

I am relying on notation using the @@ and <<||>> I found somewhere
in the
documentation yet I did not find a proper discussion of exactly how it
works.  I don''t feel that I have a proper understanding of how it
works.

What I understand is that by using the

@@name {}

I can load data into a "global object" that is accessible from any
puppet
member. Who uses the

name <<||>> 

Notation to call the data stored in that global object.

I believe that in the past I was able to view this information on my puppet
server with 

ralsh nagios_host

It would give me a listing of what was stored in nagios_host.  Now when I do
this I see nothing.

Here is a listing of what I understand as being a way to use this:
 
Is this correct? 


-----------------
class nagios-server{
       ........ A bunch of other stuff ..........
    file { "/etc/nagios/":
        ensure => ''directory'',
        mode => 755,
        owner  => nagios,
        group  => nagios,
        recurse => true;
    }
Nagios_host  <<|target ==
"/etc/nagios/nagios_hosts.${fqdn}.cfg"|>>
}
-----------------
class nagios-client {
    @@nagios_host { $fqdn:
        target => "/etc/nagios/nagios_hosts.${fqdn}.cfg",
        ensure => present,
        alias => $hostname,
        address => $ipaddress,
        use => "my-servers",
        check_command => "check-host-alive",
        max_check_attempts => 3,
        hostgroups => "my-servers",
        contact_groups => "admins",
    }
    ........ A bunch of other stuff ..........
}
-----------------

Could someone please point me in the right direction to some documentation
that could help clarify this  the use of the @@ and <<||>>?


I''d greatly appreciate it.

Thanks

Greg

Re: [Puppet Users] Nagios Module and use of the @@ and <<||>> notation

Hi Greg,

I''m on my phone at the moment so I don''t have the exact link
handy, but there is a module on GitHub that works.  I tinkered with it a lot in
my old setup but found most of my problems were due to not really understanding
how the collect/export functionality worked.

This is my favorite feature of Puppet.  When I got it working, I teared up a
bit.  :)

I believe it''s http://github.com/DavidS/puppet-nagios

Re: [Puppet Users] Nagios Module and use of the @@ and <<||>> notation

Stephen, 

Ah the David Schmitt nagios module. This is what I based my work on. I used
it as a model. 

Are you aware of any documentation that clearly explains how this
collect/export functionality works?

Exporting and collecting resources relies on stored configuration[1] 
being enabled on your Puppet Master. You should ensure that the database 
is configured and working before trying to export and collect resources.

Re: [Puppet Users] Nagios Module and use of the @@ and <<||>> notation

Avi, 

I am exporting my resources to the database. I can verify that this is
occurring.  Yet I am not getting all of the the

Nagios_host <<|target ==nagios_hosts.${fqdn}.cfg|>>

files written to my nagios server and I am interested in finding out how to
trace down this functionality of the collection and exportation of resources
so I can properly identify how/why it is not working in all of the cases.

I guess if someone could point me to a basic model of this exportation and
collection process I could work from there.  Is there any detailed writing
about this?

Greg

Not other than what folks have pointed to already, I think.  I use this:

,----[ client.pp ]
|     @@file { "/etc/backuppc/${fqdn}.pl":
|       owner   => ''backuppc'', group =>
''www-data'', mode => 0444,
|       content =>
template(''backuppc/backuppc-client-config.pl.erb''),
|       tag     => "backuppc-client-${backuppc_server}"
|     }
`----

,----[ server.pp ]
|   File <<| tag == "backuppc-client-${fqdn}" |>> {
|     require => [Package["backuppc"],
File["/etc/backuppc/SDBackupPC.pm"]],
|     notify  => Service["backuppc"],
|   }
`----

...which works fine for our infrastructure.  It looks pretty much identical to
your code, but just in case. :)

I''m not sure if you mean that you expect ralsh nagios_host to return
what has been exported and stored in the "storedconfig" SQL database,
but if you do this isn''t accurate.

ralsh nagios_host will use the resource abstraction layer to query the current
state of all resources of type nagios_host as they exist, not as
they''re stored in the database.

Does the distinction make sense?  It might help to run "ralsh user" or
"ralsh group" to see how the ouput compares to the resources as they
exist on the system.

Hope this helps,
