Puppet users - Mar 2013 - How to iterate over a string to construct nagios_service check as exported resource?

Dear all,

I wrote a custom fact, which returns a comma separated list of addr:port, 
like this: 
    
>     sb_intl_conn => 
> sbcms-t:22,sbsql05-wvuk-inst5:1434,sborc07-uk-t:1533,..,..,..

The number of elements in the string varies from node to node. I need to do 
a Nagios tcp-port-check on each of them. I think
sb_intl_conn.split(",")will turn this string into an array and then
how can I iterate over it to
do something like this? 


    @@nagios_service {
"check_stat_${::fqdn}_${addr}_${port}":
>         use                 => ''generic-service'',
>         check_command       =>
"remote-nrpe-tcp-check!${addr}!${port}",
>         service_description => "V2::CON: ${addr} [Palms]",
>         display_name        => "Connection check:
${addr}:${port}",
>         servicegroups       => ''batch-worker'',
>         hostgroup_name      => ''batch-job'',
>     }
>
Any help would be greatly appreciated. Cheers!!

It''s pretty tricky to "program" puppet like your usual
programming language.

Given the nature of how puppet does things you will have to write a define
that accepts the array you have split and then split the $title variable on
","

That looks like a very complex way of generating nagios services.

I am going to hope that the services you are monitoring aren''t managed
by
puppet at all and that''s the only way to do it.

Thanks Pete! Do you think you can possibly put together a lines of example code?
Just wondering, if it''s possible/easier with Ruby DSL? I
haven''t tried that yet. Cheers!!
