[Puppet Users] need urgent help with including Ruby DSL class from puppet manifests

Hi,

I have a Ruby class in "nagios" module - it''s located in
nagios/
manifests/ssa_nagios_checks.rb
and looks like this

hostclass :ssa_nagios_checks do
...
end

In nagios/manifests/init.pp I have

class nagios::server {
...
   include ssa_nagios_checks
...
}

And I get the following error

....
debug: importing ''/etc/puppet/modules/nagios/manifests/
ssa_nagios_checks.rb'' in environment production
err: Must pass a parameter or all necessary values at /etc/puppet/
modules/nagios/manifests/init.pp:19 on node mon1a.internal

I could not find nothing on the web regarding this specific error
message. What does it actualy means?

Then I change to

class nagios::server {
...
   include nagios::ssa_nagios_checks
...
}

I get error

...
debug: importing ''/etc/puppet/modules/nagios/manifests/
ssa_nagios_checks.rb'' in environment production
err: Could not find class nagios::ssa_nagios_checks for mon1a.internal
at /etc/puppet/modules/nagios/manifests/init.pp:20 on node
mon1a.internal

Also instead I tried to use ssa_nagios_checks.rb from another module
I have another puppet class in "ssa" module
located at  ssa/manifests/nagios.pp which has

class ssa::nagios {
  ...
  include ssa_nagios_checks
  ...
}

And I''m getting the following error:

err: Could not find class ssa_nagios_checks for mon1a.internal at /etc/
puppet/modules/ssa/manifests/nagios.pp:5 on node mon1a.internal

Then I change to

class ssa::nagios {
  ...
  include nagios::ssa_nagios_checks
  ...
}

Since ssa_nagios_checks is under "nagios" module - and still I get:

err: Could not find class nagios::ssa_nagios_checks for mon1a.internal
at /etc/puppet/modules/ssa/manifests/nagios.pp:5 on node
mon1a.internal


I have no ideas how to solve these 2 problems  - which are - how do I
properly use Ruby DSL class in the same module and how do I use it in
another module?

Thanks
Alex

I may be wrong here but I guess you cannot mix manifests written in ruby
DSL with classes written in pure puppet DSL.

The autoloader/module layout recommendations/rules haven''t been
followed.

You actually want something more like:

nagios/manifests/server.pp:

  class nagios::server {
    include nagios::ssa_nagios_checks
  }

nagios/manifests/ssa_nagios_checks.rb:

  hostclass :''nagios::ssa_nagios_checks'' do
    notice(["should work"])
  end

This should work. Can you test it?

Remember that sub-classes belong in their own file ... and only the
class with the same name as the module belongs in init.pp. Also - you
have to fully qualify class names when declaring them in their rb/pp
file.

[Puppet Users] Re: need urgent help with including Ruby DSL class from puppet manifests

Hi Ken,

Thank you so much for your reply
I did like you said BUT i was still getting the error

err: Must pass a parameter or all necessary values at /etc/puppet/
modules/nagios/manifests/server.pp:19 on node mon1a.internal

Then I started to insert notice statement in the ruby DSL class - it
turns out I a logical erro in the code.
Arghhh - I have been so fooled by the totally misguiding error
message.
Shouldn''t puppet err indicate that there is problem in /etc/puppet/
modules/nagios/manifests/ssa_nagios_checks.rb and not in /etc/puppet/
modules/nagios/manifests/server.pp?

Anyway now that the ruby error is fixed I get new error
err: undefined method `Puppet'' for #<Puppet::DSL::ResourceAPI:
0xb73f50e0> at /etc/puppet/modules/nagios/manifests/server.pp:15 on
node mon1a.internal

What does this error means?

Here is the real ruby dsl class code - in case it''s again a problem
with the class :)

----------------
require ''json''
require ''open-uri''

hostclass :''nagios::ssa_nagios_checks'' do

  nagios_confdir =
scope.lookupvar(''nagios::params::nrpe_confdir'')

  url = "http://localhost:5984/nagios_alerts/_all_docs?
include_docs=true"
  result = JSON.parse(open(URI.parse(url)).read)

  result[''rows''].each do |x|

    type = x[''doc''][''type'']
    args = x[''doc''][''args'']
    warning_threshold =
x[''doc''][''warning_threshold'']
    critical_threshold =
x[''doc''][''critical_threshold'']

    contacts = x[''doc''][''contacts'']
    contact_groups =
x[''doc''][''contact_groups'']
    notification_period =
x[''doc''][''notifications_period'']

    case type
    when "mysql"
      mysql_user = ''nagios''
      mysql_password = ''xxxx''
      check_command = "check_mysql_health_sql_tresholds!#{mysql_user}!
#{mysql_password}!''#{args}''!#{warning_threshold}!
#{critical_threshold}"
    when "api"
      check_command = "blah-blah"
    else
      raise Puppet:Error, "Unsupported ssa nagios check type $type"
    end

    nagios_service(
"ssa_#{x[''doc''][''_id'']}",
      :target              => "${nagios_confdir}/app_alerts/ssa/
services/${name}.cfg",
      :host_name           =>
x[''doc''][''hosts''],
      :service_description =>
x[''doc''][''desc''],
      :use                 => ''generic-service'',
      :check_command       => check_command,
      :require             => "File[#{nagios_confdir}/app_alerts/ssa/
services]" )

  end

end
----------------

Thanks
Alex

Re: [Puppet Users] Re: need urgent help with including Ruby DSL class from puppet manifests

Is it this line?

raise Puppet:Error, "Unsupported ssa nagios check type $type"

Should be double colon ... Puppet::Error.

Looking at your code, I can''t help but think a function is a better
fit then Ruby DSL.

[Puppet Users] Re: need urgent help with including Ruby DSL class from puppet manifests

Thanks Ken that finaly solved the problem with the ruby dsl class and
it''s working now.

I don''t quite understand why you think implementing ruby function is
better fit - what I need to do is iterate over
all records in couchdb and create a puppet resource for each one of
them - that''s the reason I use ruby dsl and not puppet defines.
But how is puppet function going to help me - I won''t be able to reuse
it in other places - so I don''t want to create
a functions instead of each hostclass i need.

Thanks

[Puppet Users] Re: need urgent help with including Ruby DSL class from puppet manifests

Error:

Must pass a parameter or all necessary values at /etc/puppet/
>
Is because when using Ruby DSL, assumed variables $name and $title are not 
passed to Puppet resource. 
For example, fix this:

     create_resource :''server::vhost'',
''example'',
          :ensure => ''present'',
          etc...

To this 

     create_resource :''server::vhost'',
          :name => ''example'',
          :ensure => ''present'',
