This is a continuation of the series Why We Monitor. This time we are going to look at DNS, why we monitor it and what to monitor. The Domain Name System ( DNS ), among other things, is what allows us to have cute and memorable names for a web service instead of memorizing the ip of the local server that runs it. When it’s working, the DNS system gives all sorts of information about your domain. When it’s down it doesn’t matter how good your application is, no one will be able to find it. When it’s hijacked a person could send your users to another site or imitate your site and steal your user’s logins ( if your site uses clear text authentication forms ). I am going to run through some basic monitoring that can help you avoid issues.
