DNS IP Match is CRITICAL

[RIDS_I2MP]

Hello Team,

We are monitoring a DNS server, getting below error in the service.

DNS CRITICAL - expected '10.144.223.152' but got 'name = eu1papw196.shareprod.org.'

Server name: eu1papw196.shareprod.org
IP: 10.144.223.152

I have tried replacing the name in argument with IP and server name both, but getting the same error.

Kindly, help us on this issue on priority.

Hello,

Can you go to Configure > CCM and click on the Services link from the left hand menu, and then find this service and click on it. Next, from the Common Settings menu click on Run Check Command. Run the check command and post a screen shot, so we can see the exact check command and its arguments.

Thanks.

Aslo, is there a chance this is a dynamic DNS as I ran an nslookup on the domain name and it returned a different IP address than in your post.

Hello,

I am attaching the screen shot here.

Also, we checked with the owner of the server if this is a dynamic DNS, he informed us that DHCP is not enabled.

Hello,

What domain are you expecting to return or checking? When testing this on my system, I'm getting a different IP address then what you have?

Hello,

I have also checked the nslookup command and getting below output:

[nagios@eu1papu003 ~]$ nslookup eu1papw196.shareprod.org
Server: 10.144.223.14
Address: 10.144.223.14#53

Name: eu1papw196.shareprod.org
Address: 10.144.223.152

[nagios@eu1papu003 ~]$


We are expecting the shareprod domain and IP is 10.144.223.152 only.

Hello @RIDS_I2MP,

Please let me know which wizard you are using to set up this service. I tested this using the DNS Query Wizard in Nagios XI and it will setup the command definition as follows.

For example, the command definition:

Code: Select all

$USER1$/check_dns $ARG1$

and then set $ARG1$ = -H eu1papw196.shareprod.org -a 10.144.223.152 for the IP match and $ARG1$ = -H eu1papw196.shareprod.org for DNS resolution.

For the IP Match:

For the DNS Resolution:

Hello,

We were using the same config wizard, not sure how the check_command was different.

I have made the changes as per your screen shot and now its working fine.

Thanks a lot for your help!!
