Hey thanks for the feedback, dozzie. We're glad you don't use Nagios either. We think that Watchdog is a valuable resource for the HN community, which is why we posted it on Show-HN. Unlike Nagios or any other competing server monitoring tool out there, Watchdog is completely config free and installs in about 23 seconds. We are proud to show if off and hope you would try it out. It's definitely not late by 5-6 years.
BTW, you do realize that nobody trendy uses Nagios anymore, so you're late to the party by half a decade?
