My first Nagios plugin in Go
An important feature of the #Nagios monitoring system (or of its compatibles like the one I use, #Icinga), is that you can easily write your own plugins, to test things that cannot be tested with the “standard” Nagios plugins. I wrote several such plugins in my life, to do tests which were useful to me. This one is the first I wrote in #Go, and it tests a #DNS zone by querying every name server, thus checking that all name servers are OK.
