Hi, I've just enabled some additional alerting for the DNS secondary service. It will copy you in on alerts regarding BitFolk nameservers that are not correctly serving your domain. They look like this: From: nagios(a)bitfolk.com Subject: ** PROBLEM alert - a.authns.bitfolk.com/Auth. DNS example.com is UNKNOWN ** ***** Nagios ***** Notification Type: PROBLEM Service: Auth. DNS example.com Host: a.authns.bitfolk.com Address: 85.119.80.222 State: UNKNOWN Date/Time: Fri Jan 27 19:46:10 UTC 2012 Additional Info: DNS UNKNOWN - 1.444 seconds response time (No ANSWER SECTION found) This would indicate that a.authns.bitfolk.com is not serving the domain example.com when we would expect it to be. The reason for this change is that there are quite a few customer domains that aren't being served correctly and rather than keep opening tickets and chasing it up, I would rather let Nagios do what it is designed for. I am also working on a check that AXFRs are happening. Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting
