The yaml contains a complete report of what's going on though, so you can parse that for errors and change the message string accordingly and probably even parse it a little more thoroughly so even --test doesn't report any changes. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I'm not at all "ruby-ready" as it were, in terms of programming skill, but it occurs to me that I can think of other conditions I'd be interested in reporting upward (syntax or other errors in the catalog received, or anything really, which causes a cached catalog to be used).

Re: [Puppet Users] Trigger an event after a puppet run
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
http://pastie.org/private/drn1jj65tu5v8ljsdfkvwa
#!/bin/sh
# SUBMIT_CHECK_RESULT
# Written by Ethan Galstad (egals...@nagios.org)

Yeah I twigged just after posting that a report is probably the best way to do this so i can analyze the results at the moment I have this : require 'puppet' Puppet::Reports.register_report(:nagios) do Puppet.settings.use(:reporting) desc "Sends reports directly to Nagios" def process begin exec "/usr/lib/nagios/eventhandlers/submit_puppet_result 10.30.0.101 puppet-report 0 \"There has been no change\"" end end end http://pastie.org/1567064 in case email formatting munges things and i've configured puppetmasterd like so reports = log, store, rrdgraph, smt, tagmail, nagios but when I do a puppet run I get 2011-02-15T17:00:24.00+00:00 vfantmon1 puppetmasterd[28860]: Report nagios failed: no block given any idea what i've done wrong?

[Puppet Users] Trigger an event after a puppet run
Hi, We'd like to run puppet regularly in noop then trigger an event after the run depending on the results, namely to hook puppet in to our Nagios implementation so that if anything changes for any reason we receive an alert. We already have puppet configured to send out puppet reports via email but don't want to completely rely on that. Is it possible to craft a trigger of some sort so that after a run we can run a shell script which goes 'ok, nothing has changed, send nagios an OK' or 'omg changes, send nagios a CRITICAL and wake everyone up' ?
