Nagios critical error 800 days old

Well, almost 3 years ago your DNS server changed, the person in charge of Nagios did not know how to change the check and disabled the notifications so it would not bother him/her.

Check the services inside /etc/nagios3/conf.d/ until you find the culprit.

HTH,
Dan

i would look at the command being used
i'm guessing it is using check_dig
look at the command line; possible it was not setup correctly

Aha! I found this fellow in services conf file

# check that ssh services are running
define service {
    hostgroup_name           internal-dns-servers
    service_description      Internal DNS
    check_command            check_dig!coxxx-server.corp.ok7-eleven.com
    use                      generic-service
}

define service {
    hostgroup_name           store-internal-dns-servers
    service_description      Internal DNS
    check_command            check_dig!coxxx-server.corp.ok7-eleven.com
    normal_check_interval    10
    max_check_attempts       10
    use                      generic-service
}

Digging... need a few

look at the command using check_dig and see what parameters are being used

Okay,

For sure the solution is in the two config files .

My problem now is finding out what server should go where.

There 3 to choose from.

The one that is in the command check_dig! does seem to be doing anything now yet it does respond to a ping.

Asking around to get the right idea.

I am stuck figuring out what name DNS server to put there ( I found 4). That is a beside the issue that you helped me with

Thank you!
