There are some unfortunate side-effects when trying to use this plugin to monitor the DNS response from a specific server. If the server supplied to the plugin on the commandline fails to respond, the nslookup cmd will fallback to using servers in the monitoring nodes /etc/resolv.conf. So a failing server will appear to work if any of those other servers respond... Anyone thought to move this plugin to use 'dig'? </tt><tt>will risk being sent to /dev/null </tt> </body></html>
