Re: [Nagios-users] Notification period inheritance problem
I don't understand why this is confusing.
You have a service template that defines a timeperiod. All services
that use that template will inherit the notification_period value from
the template, if they don't specify a notification_period themselves.
By setting "notification_period null" in your service definition, you
are explicitly overriding all forms of inheritance and setting the
notification_period to null, which happens to be a special
notification_period.
So, the issue you are running into is due to you expecting implied
inheritance to take precedence over values defined in the service
definition itself. This would break the documented and expected
behavior of inheritance, and a lot of people's configurations.
Now, I understand how you could run into this issue. But take a look
at the documentation again:
>>> Quoting from the documentation:
>>>
>>> The following table lists the object variables that will be implicitly
>>> inherited from related objects if you don't explicitly specify their value
>>> in your object definition or inherit them from a template
The implied inheritance variables will only be inherited from related
objects, if they are not specified in either the object definition or
template. In your case, notification_period is defined in your
template, so the implied inheritance is already overridden. You can't
bring that back by also explicitly defining a notification_period in
your service definition, even if that happens to be null, as null is
also a valid value for notification_period.
Something that definitely would work is for you to define another
service template without a notification_period value, and use that for
checks you want implied inheritance from.
Something that might work, but unfortunately I can't try it as I've
already spent too much time on this email :-), is to set
notification_period to null in the template, which could mean that the
service definition will behave as though the notification_period value
is unset in the template. This would allow you to let the "null
notification period" template inherit from your normal template.
Best regards,
Martin Melin

Which means that I have to expand the template where I null-ify the
notification period with the values from any of the templates it
"uses". That seems like a minor inconvenience, but it's still uglier
than it ought to be. When I do so, I still get the warning from "nagios
-v". I'll test it to make sure that it's working.

If that's so, then at the very least the documentation should be updated
to note that this won't work.

That sure looks like a bug to me. Even the indentation looks weird to
me, is that the normal style? I can't imagine why "null" would be
considered a valid notification period. If
have_notification_period=TRUE were in the preceding block, the
documentation would make more sense, and implied inheritance would be a
lot easier to use. Do you think a patch to modify this behavior would
be accepted?
Thanks for the explanation. I appreciate your help.

[Nagios-users] Nagios 3.2 and max_concurrent_checks=0
I'm doing some testing for migrating our installation to Nagios3.2. The test server is running 3.2 on an 8 CPU box with 34,000 active service checks and 3,000 active host checks. The initial configuration file had max_concurrent_checks=0, but latency was about 9,000 seconds. I changed it to max_concurrent_checks=200 and the latency went down to about 7,000 seconds. I then set it to 2,000 and the latency dropped to about 200 seconds. I currently have it set to 100,000 and latency has not changed from about 200 seconds. >From all the documentation I have seen, if max_concurrent_checks is set to >zero, there should be no limit on the number of concurrent checks, but this >doesn't appear to be the case.

Don't specify the directive in the template.

You're mixing sections of the documentation to try to make a connection that
doesn't exist. Again, specified with a value of 'null' does not equate to
unspecified. Looking at the code, if you specify the value in any way,
including a value of 'null', it breaks the implied inheritance.
xodtemplate.h --
#define XODTEMPLATE_NULL "null"
xdata/xodtemplate.c --

'If the variable is "notification_period" and the value is not the word "null",
save the value unless the value is blank (error otherwise). If the value is the

temp_service->have_notification_period=TRUE;
}
"If the service 'have_notification_period' flag is not TRUE and the host and
the host has a notification period, use that for the service."
As you can see, you fail that first condition.

If you don't specify the value in the template, there's nothing to inherit from
the template. If the directive is also not specified in the service{}
definition, the template engine will look to the value in the host{} definition.

BestettiOpServices I had to install a bunch of nagios for 40 polls. We ran some tests on bi-Xeon Dual-Core with 4Go.

Re: [Nagios-users] Notification period inheritance problem
Have you tried leaving out the notification_period line from the
service definition? I think, but don't have time to verify, that by
saying "notification_period null" you are actually overriding all
inherited values for notification_period and setting it to null
instead.
Best regards,
