Nagios Support Forum

I upgraded my Nagios xi installation last night to 5.7.4 (from 5.6.x) and everything appears fine, except for one error.

I have a web service that I've monitsored for some time, and one of the checks is DNS Resolution. It is now throwing this error:

"DNS CRITICAL - query type of -querytype=A was not found for 10.110.150.105

I tried changing the hostname to the FQDN, but it still errors in this way. I don't see this problem from other DNS Resolution checks that I'm doing.

How do I address this? Thanks!

Hi,

There was a syntax change in the latest version of check_dns. If you can post the full check command I can confirm this for you. The following thread has some information about the change and how to correct it.

Hrm. When i go to reconfigure service, it sends me to the CCM.

In the CCM, there is no check command defined, but it is using the xiwizard_website_dns_service as a template, and appears to have no other parameters.

Ok, and I found that under service templates, and it has the command listed as:

$USER1$/check_dns -H $HOSTADDRESS$ $ARG1$

Hi,

The easiest method to view the full check command and to test this from the CLI is the go to Configure > CCM and then find the service and select the Run Check Command form the Common Settings tab.
For detailed instructions, please see the knowledgebase article below. Once you retrieve the full check command, please post it to the thread for us to review. Thanks.

Nagios xi - How To Test Check Commands From The Command-line

That was where I looked. It is completely blank.

Hi,

Well, that's odd. Did you use the wizard to set this up? You should see something like this: I would try to re-run the wizard. However, before doing that, make sure you have the latest version of the Wizard. Go to Admin > System Extensions > Manage Config Wizards, and then select the Check for Updates button, and then update if needed.

Otherwise, send me the system profile and I can track down the settings in the configurations. Thanks, Benjamin

To send us your system profile.
Login to the Nagios xi GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button

I deleted and re-added the website with the wizard, and it works properly now. Thanks for the assist!
