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
