A munin plugin that allows you to monitor the response time of any DNS that allows you to recurse.
dnsresponse_ — it’s a poor man’s smokeping DNS probe :)
(wordpress.com does not allow arbitrary file uploads, so grab it from munin-exhange)
To install it, place it in /usr/share/munin/plugins/ and run «munin-node-configure –shell«.
By default it graphs the Average, Median and StdDev of 20 DNS queries.

nice!
thnx :)
