But if the only way I can be sure that Nagios will check the hosts that only require a ping every minute is to add ping as a service, I guess that's what I'll have to do. Slightly frustrating but I'm sure we'll learn to live with it. Thanks a lot.

I'm not sure what would cause that... AFAIK in Nagios 3 host checks end up in the same queue as service checks, so the only explaination I could fins would be: 1. Your interval_length is larger than the default of 60 2. check_result_reaper_frequency is too large (will delay the results, and therefore delay the time at which nagios will re-schedule the checks) 3. Various commands (notifications, event handlers, performance data) slowing down nagios (those are serialized just like host checks in Nagios 2 - see below) >> In Nagios 2 hosts check were normally on-demand so it wouldn't work if >> your service always returns OK. > > Interesting. I never used Nagios 2. The logic in Nagios 2 is to check host only when a service fail, and it does not support assync host checks (only service checks are assync). The problem with it is that the host checks are serialized, so it adds an artificial limit at which they can be performed (the time it takes to detect a host down). This was an annoying bottleneck on huge setups. > According to check_dummy -h: > This plugin will simply return the state corresponding to the numeric > value of the argument with optional text > > Am I right in thinking that this does not actually perform a test?

Re: [Nagios-users] Can I monitor a host without defining any services for it?
It probably does serve a purpose, just not for what you are trying to accomplish. Though warnings are given about not having services associated, you should be fine with just host checks if that is what you want. As far as the checks go, I have 101 servers and over 1200 service checks and have never noticed a time lag with any of them. Would be best to use check_ping with your check_command directive for your hosts.

[Nagios-users] nrpe and sudo
Hello,
I am trying to run sudo /usr/sbin/clustat -s $service -l from nrpe.
I can run it on the nrpe machine as the nagios user and it works fine.
However, when I call it from my nagios machine via check_nrpe it is
not working. Since sudo works locally, it is something with nrpe in
how it is calling the sudo command that is making sudo not match. my
sudoers is pretty open as it sits right now for testing:
nagios ALL=(ALL) NOPASSWD: ALL
I even broke it down to a very simple script:
#!/usr/bin/perl
use lib "/usr/lib64/nagios/plugins";
use utils qw(%ERRORS);
$command = "sudo /bin/echo shit";
$foo = `$command`;
print "$foo\n";
exit $ERRORS{'OK'};
I get this from the other side:
CHECK_NRPE: No output returned from daemon.
I see that you can prefix all commands with sudo in the nrpe.cfg but I
only need it for a few plugins so would rather just call it from the
script.
Anyone have any thoughts?
Thanks!

[Nagios-users] Comments not allowed in Nagios 3
Hello I have been running Nagios 1, 2 and now 3 for some years. Mostly in very small environments. Now I have a little more requirements and wants to enable 'Comments'. I have searched around and can not find the solution for enabling Comments for Nagios 3. I get the 'Sorry, but you are not authorized to commit the specified command.' I just want to put a comment, not run any command. :-( Thanks in advance.

You can use check_dummy for the service... In Nagios 3 with regularly scheduled hosts checks it should work. In Nagios 2 hosts check were normally on-demand so it wouldn't work if your service always returns OK. - -- Thomas -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFImuHT6dZ+Kt5BchYRAmifAKCMPDrEFe7eAh4nxOksLuMGGLfI5wCg2sOY d9KUNyafcsCGygv+X/DuUiI= =p0pC -END PGP SIGNATURE- - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ 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

They can be filtered out at the service and contact levels - check their
definitions too.

[Nagios-users] Can I monitor a host without defining any services for it?
Hello I was wondering about the necessity to define a service for hosts that I just want to ping. As far as I understand, the default Host Check Command, check-host-alive, is a ping check and looking at my scheduling queue, these checks are being done regularly but when I verify my config files Nagios always warns me about the hosts which have no services defined. So I looked in the documentation and found this: http://www.nagios.org/faqs/viewfaq.php?faq_id=39 On that page Ethan Galstad says: You really need to define at least one server per host that you plan on monitoring. Although you can define a host and not assign any services to it, you will not get the results you are expecting. Nagios is primarily geared towards monitoring services - hosts are only checked when there are problems or recoveries with services, so things will go awry if you define a host without any services. The above FAQ was written in 2002. Is this still true? Since the host is already being checked by the Host Check Command, it seems redundant to specify a ping check as a service. Do all you Nagios admins define a ping service, if you only want to check if a host is up or down?
