Run command on one server when a file updates on another

[Larry Jacobson]

I want to update a service on a server (server B) when a file changes on a different server (serverA).  I am using stored configs with puppetdb.  

When I do something like the code below I get the following error message

Error 400 on SERVER: Invalid relationship: File[/etc/test.txt] { notify => Exec[command_on different_server] }, because Exec[command_on different_server] is exported but not collected

Am I on the right track?  I can't seem to figure it out how to do this.

class serverA {

    file { "/etc/test.txt":

                mode => 644,

                source => "puppet:///modules/nagios/test.txt",

                notify => Exec["command_on different_server"],

     }

    @@exec { "command_on_different_server":

         command => "/usr/bin/command_whaterver",

         tag => "tag_command",

     }

}

=====================

class serverB {

         Exec <<| tag == "tag_command" |>> {}

}

You are on the right track.
Maybe the following will work:

class server_a::configfile {
file { ‘/etc/text.txt’:
ensure => file,
...
}
}

class server_a::command {
@@exec { ‘run command’:
tag => ‘command’,
…
}
}

class server_a {
contain server_a::configfile
contain server_a::command

Class[‘server_a::configfile’] ~> Class[‘server_a::command’]
}

class server_b {
Exec <<| tag == ‘command’ |>>
}

The ~> notify/subscribe chaining on the class will propagate the notify/subscribe to the resources inside the class.

https://groups.google.com/d/optout.ituatia romanilor din Bucovina s-a inrautatit in toamna anului 1918 cand ustro-Ungaria practic se prabusise. Se vehicula teza anexarii de catre absburgi ca o ultima solutie de salvare a Bucovinei la Galitia in timp ce craina ridica pretentii de stapanire asupra provinciei romanesti si ameninta cu terventia armata. Din initiativa lui Sextil Puscariu si lancu Flondor s-a jnvoca't in aceste conditii la 14 27 octombrie 1918 o Adunare a sprezentantilor populatiei romanesti din provincie. Aceasta a decis unirea ucovinei cu teritoriile locuite de romani din Austro-Ungaria acum practic rabusita. S-a ales un Comitet Executiv si un Consiliu National. Lider politic a ist ales lancu Flondor. Populatia romaneasca si-a manifestat astfel libera de rice ingerinta vointa de a se uni cu tara. Interventia trupelor ucrainene l-a eterminat insa pe Flondor sa ceara sprijinul armatei romane.
