I'm fed up so I thought I'd turn to you guys and see if you can stop
me from setting fire to my office. I'm trying to add
nagios::service{} statements to various modules throughout my
configuration, but ONLY if the node in question uses a define of
nagios::target. This is so I don't break nagios constantly by adding
apache on unmonitored hosts.
In nodes.pp: (this is hlslinutil1, the nagios server itself)
# Must be before other modules!
nagios::target{ "": notification_period => "24x7" }
include nagios
defaultclass{$environment:}
include commvault
include puppetmaster
include splunk::client
include cobbler
nagios/manifests/defines.pp:
define nagios::target(
$notification_period = "24x7"
){
nagios::host {$fqdn: notification_period => "$notification_period"}
nagios::service::ping{$fqdn:}
nagios::service { "ssh-$hostname":
host_name => "$fqdn",
check_command => 'check_ssh',
service_description => "ssh-$hostname",
}
}
apache/manifests/init.pp:
if defined(Nagios::Target[""]) {
if $apachelistening80 == "true" {
nagios::service { "http-$hostname":
host_name => "$fqdn",
service_description => "http on $hostname",
check_command =>
"check_http_url!$fqdn!/serveralive.html";
}
}
if $apachelistening443 == "true" {
nagios::service { "https-$hostname":
host_name => "$fqdn",
service_description => "https on $hostname",
check_command =>
"check_https_url!$fqdn!/serveralive.html";
}
}
}
-------------
The nagios module includes apache, so what I wanted to see was:
nagios::target is called.
nagios is included.
apache is included -> does the check, sees nagios::target already
called, adds the two nagios::service statements.
What I see is:
no monitoring on apache at all.
I have tried dozens of ways around this but I just cannot work out
what the hell is wrong. I can't do defined(Nagios_host) (adds apache
monitoring for all hosts), I can't do defined(Nagios_host["$fqdn"])
(doesn't work at all again) and I'm out of clever ideas. It's almost
as if it checks the defined() against the puppetmaster rather than the
client. Someone rescue me?
