Re: [Puppet Users] Trigger an event after a puppet run

[Rus Hughes]

Thanks for the help guys, I've now finished it and got a working
solution. For anyone replicating this you need to configure a passive
service check on each host called puppet-report which then will get
updated.

http://pastie.org/private/812ijdrd7gwmwgxfmc9rdq

require 'puppet'
require 'socket'

Puppet::Reports.register_report(:nagios) do
    Puppet.settings.use(:reporting)
    desc "Sends reports directly to Nagios"

    def process
        tree = YAML::parse(to_yaml)
        host = tree.select('/host')[0].value
        ip = IPSocket::getaddress(host)

        size = self.logs.size
        if size == 0 then
            system "/usr/lib/nagios/eventhandlers/submit_puppet_result
" + ip + " puppet-report 0 \"There has been no change\""
        else
            system "/usr/lib/nagios/eventhandlers/submit_puppet_result
" + ip + " puppet-report 2 \"There have been " + size.to_s + "
changes\""
        end
    end
end

which calls the following bash script

#!/bin/sh

# SUBMIT_CHECK_RESULT
# Written by Ethan Galstad (egals...@nagios.org)
# Last Modified: 02-18-2002
#
# This script will write a command to the Nagios command
# file to cause Nagios to process a passive service check
# result.  Note: This script is intended to be run on the
# same host that is running Nagios.  If you want to
# submit passive check results from a remote machine, look
# at using the nsca addon.
#
# Arguments:
#  $1 = host_name (Short name of host that the service is
#       associated with)
#  $2 = svc_description (Description of the service)
#  $3 = return_code (An integer that determines the state
#       of the service check, 0=OK, 1=WARNING, 2=CRITICAL,
#       3=UNKNOWN).
#  $4 = plugin_output (A text string that should be used
#       as the plugin output for the service check)
#

echocmd="/bin/echo"

CommandFile="/var/log/nagios/rw/nagios.cmd"

# get the current date/time in seconds since UNIX epoch
datetime=`date +%s`

# create the command line to add to the command file
IP=$1
SERVICE=$2
RESULT=$3
MSG=$4
cmdline="[$datetime] PROCESS_SERVICE_CHECK_RESULT;$IP;$SERVICE;$RESULT;$MSG"

# append the command to the end of the command file
`$echocmd $cmdline >> $CommandFile`
