Thanks for your answer. What would help me, and I’m sure others, is if the documentation were to be presented in such a way is to show both the nagios and check_mk requirements for checks. Perhaps a matrix, which would show that if you want to run a certain check, does it require something from nagios. If yes, show the nagios configuration specifically for that check, along with the check_mk configuration. I understand that more work needs to be done with the documentation. But I think that my approach might help more, since check_mk is dependent on nagios to do what it does.

I understand the approach your taking but I think you’ll find that using a hybrid of the two is the best approach. check_mk is meant to replace the client side checks which would normally be executed by NRPE, check_by_ssh, nsclient, etc, not the remote checks the nagios server runs. I realize it would be nice if you could use check_mk to configure all aspects of nagios, even the nagios plugins, but that’s kinda outside the scope of check_mk…at least for now.

Darin,
I was going to use one of the nagios plugins, but I wanted to see what check_mk itself provided for doing this. I’m trying to do most of my work through check_mk, as opposed to nagios plugins where possible.
Thanks

Why don’t you just use the check_dns Nagios plugin to query the server? It’s bundled with the nagios-plugins on OpenSuSE and is probably just what your looking for.

Hans,
Thanks for your response. But I’m not sure how your recommendation is going to help me with dns lookup. Can you please clarify?

Hi David,
Check and see if you switches or firewalls are only allowing 512 bytes to pass. 2008rc2 is
enabled to use edns, ipv6, by default. If ipv4 only solves your problem you do have a problem
with one of the switches/firewalls.

I’m running check_mk 1.1.10p3, with Nagios 3.3.1, on Centos 5.
We have a Windows 2008 R2 server that’s providing DNS for our network. For some reason the DNS service crashed, but the Windows event viewer showed that its status was still running. Restarting the DNS service resolved the issue, but now I need to both monitor the DNS service and make sure that it’s indeed running. I’ve modified my main.mk to add a check to monitor the DNS service, and that’s working. But is there a way to do a DNS lookup, so that I can verify that the DNS service is working? I could use a Nagios plugin, but I’d like to see what I can do with Check_mk itself.
Thanks
