Re: [Nagios-users] hostgroup with no members - Enhancement
Well, we're running 3.2.3, and if I don't have at least 1 member of a hostgroup it throws a fit during the test. Maybe there's something else I have to change, but last we tried it would not work. And no, I don't really want to assign hosts within the service. The way we have it now works great, because everything about a host is in one file, easy to add, delete, update. The only issue we've had is the empty hostgroup. I'll try it again today, I think last I tried was at 3.2.1 so maybe it's changed since then. Either way I'll report back on how it goes. However, your description of services sets sounds pretty interesting and sounds like it would accomplish the same thing. I don't suppose you have any pseudo-examples of what you're thinking?

Yes. That's not just an empty hostgroup, but an empty hostgroup to
which services are assigned. That's supposed to be an error. What's
the reason for using empty hostgroups to assign services to?

Re: [Nagios-users] hostgroup with no members - Enhancement
Basically because all the backend files are controlled via puppet, to a
number of nagios servers, but the actual host assignments are controlled
by third-party package. So, the base configs about all the services
are pushed to every server, and then the other tool determines the best
balance of devices per nagios server. If that makes sense. So
instead of maintaining service and hostgroup configs constantly across
all the servers, I can push out one set of configs, and if there's a
host pushed to that server which needs those configs, they are there and
ready to go.
That help?

Yes. That's not just an empty hostgroup, but an empty hostgroup to
which services are assigned. That's supposed to be an error. What's
the reason for using empty hostgroups to assign services to?

Yup. Fixing Nagios to handle this is a bit off my todo-list right now
though, but as an autofix, have the init-script run a repair-script to
sed out the offending services or hostgroups on the offending systems.
I'd let Nagios do the heavy lifting if I was you and just surround
each hostgroup with
##HGBEGIN_lalala
define hostgroup {
hostgroup_name lalala
}
##HGEND_lalala
to make sed'ing a bit easier.

Maybe it could just be considered a warning and not a fatal error? I

The code returns NULL for non-existing hostgroups referenced (which should remain an error) and NULL for existing hostgroups without member hosts. It needs to be changed to return an int and pass the data back as an out-argument, and I simply don't have time to do that just now. So yes, it could be considered an error, and no that won't happen in the foreseeable future unless someone else sends me a patch for it. I'd be delighted to apply such a patch if someone did though, and especially if it was configurable from nagios.cfg whether empty hostgroups referenced from services was an error or just a warning, with error enabled by default. The patch must not change the object layouts as defined in include/objects.h. Backwards compatibility is kinda boring to cater to, but it's necessary for projects as large as Nagios. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Nokia and ATT present the 2010 Calling All Innovators-North America contest Create new apps games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
Re: [Nagios-users] hostgroup with no members - Enhancement
Hi,
I would also like to be able to create empty hostgroups with services assigned.
The reason for this is that I've setup a nagios installation for a customer
where a host is only member to one hostgroup to inherit services from other
hostgroups, like all-windows-citrix-server and for a few special servertypes
I would like to prepare the chain with hostgroup and services so that when the
servers are ready to be monitored everything is prepared and the servers only
needs to be added to the apropriate hostgroup.
Best regards,
Fredrik Barrud

[Nagios-users] hostgroup with no members - Enhancement
I'd like to be able to create a hostgroup with no members assigned, but doesn't appear to work. The reason being is that I'm generating the host configs using a third-party tool, and it puts in that host file which hostgroups a host belong to. This works great, but there has to be at least 1 member in the hostgroup for it not to complain. It would be nice if I could just put the hostgroups out there blank and then let the host definition completely populate what's in there. Right now I have 1 fake host that is in every group, so I have one host with hundreds of service checks that will fail , just rather messy. Does that sound reasonable, another way to do this I've missed? Thanks!
