Freeware and Plugins

Description

check_windows_dns is a Windows plugin for Nagios which checks the condition of DNS supported by Active Directory systems. The plugin detects the condition of DNS and shows errors, if there are disturbances.

Documentation

Usually you run the plugin without any more details:

C:> check_windows_dns.exe

For debugging purposes, it may also be called with a more detailed output option (this mode is not suitable for continuous operation, but for testing purposes only).

C:> check_windows_dns.exe debug

Installation

Preferably the plugin is copied into the script directory where you will store your checks under Windows

When using NSClient ++ an entry in NSC.INI similar to this is generated:

...
[/modules]
NRPEServer=enabled
CheckExternalScripts=enabled

[/settings/NRPE/server] 
allow arguments=true  

[/settings/external scripts/scripts] 
check_windows_dns=scripts\check_windows_dns.exe
...

Examples

Checking DNS Controller, if everything is alright:

DNS OK: dcdiag found no errors in DNS config.
