Hi,
We currently have a module `nagios` which install nrpe and nagios
plugins for all nodes. The default node have this module included.
Currently we have a customer who wants to monitor their own services.
We will still monitor them, but they want to do their own checks, fair
enough.
How would you do this? This is what I have now:
node default {
[...]
include nagios
$nagios_allowed_hosts = ["ip1", "ip2"]
[...]
}
But we don''t want to add their source IP to this list, so thought this
would do:
Keep current default node, add this:
node special_customer inherits default {
$nagios_allowed_hosts += "ip"
}
And then inherit all of their nodes from this rather than default.
What do you think?

I just realized that this wont work, since the variable allready is
defined. The variable must also be defined before the include, since
it is used by the module.
One way to solve this would be creating a top node which contains
vars, which is inhereted by a subnode which have includes, which again
is inherited by nodes.
node top {
vars[...]
}
node second inherits {
includes[...]
}
node ''actual-node.example.com'' inherits seconds {
}
Then I could create a special tree for customers, which inherits the
right one.
Hm, while I''m writing this I see that maybe I should rather make
classes out of this rather than using nodes for this. It would make
more sense to make a class for variabels, then a class for includes,
then I''m able to change variabels in the middle.
Any toughts`?

Re: [Puppet Users] Nagios allowed hosts, how would you do it?

FWIW When I hit this awhile ago I opened a bug (http://projects.puppetlabs.com/issues/3720). Annoying, it was rejected. seph Tore <tore.lonoy@gmail.com> writes:> I just realized that this wont work, since the variable allready is > defined.
