Windows DNS-Server parents might be external DNS-Server provided by ISP or google so this upstream connection can be checked with this script
Sample nagios command definition:
define command {
# ARG1: 8.8.8.8, dns server
# ARG2: www.google.de, host_name
command_name check_windows_dns
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_dns -a $ARG1$ $ARG2$
}
Sample NSCP (Version: 0.4+) nsclient.ini:
[/settings/external scripts/wrapped scripts]
;; DNS Check
;; ARG1: DNS-Server
;; ARG2: DNS-Name to check
check_dns = check_dns.ps1 $ARG1$ $ARG2$
[/settings/external scripts/wrappings]
; WRAPPING - An external script wrapping
ps1 = cmd /c echo scripts%SCRIPT% %ARGS%; exit($lastexitcode) | powershell.exe -ExecutionPolicy Bypass -command -
Sample Output:
$ /usr/lib/nagios/plugins/check_nrpe -H -c check_dns -a 8.8.8.8 www.google.com
OK: dns returned 145.253.244.233
Or on error (this message is localized by your windows, so it might be timeout or something like this):
CRITICAL dns server 8.8.8.8: Error: *** Zeitberschreitung bei Anforderung an UnKnown
define command {
# ARG1: 8.8.8.8, dns server
# ARG2: www.google.de, host_name
command_name check_windows_dns
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_dns -a $ARG1$ $ARG2$
}
Sample NSCP (Version: 0.4+) nsclient.ini:
[/settings/external scripts/wrapped scripts]
;; DNS Check
;; ARG1: DNS-Server
;; ARG2: DNS-Name to check
check_dns = check_dns.ps1 $ARG1$ $ARG2$
[/settings/external scripts/wrappings]

No issues, and worked immediately out of the box. Great way to functionally test a DNS server from NSClient.
