I read about Vigil on the Status Board Sources page and am using it for about a week now. It’s mainly an iPhone app that does two things: it monitors websites and sends a push notification if they are not responding. It has a free one-month trial and after that costs $9.99 a year for an unlimited number of websites. I subscribed after a few days because I really liked the app and was delighted to see the year I paid for will nonetheless begin after the one-month trial is over. Classy move.
On the home screen of the app is a list of all your websites with HTTP status codes and ping time. Tapping on a website a side panel will slide over and show some more detailed data like the download speed and a graph for the ping times of the last hour.
And finally they even generate you a link for a Status Board table showing the status codes, names, ping time and speed of all your websites.
As you can see, it uses the standard Status Board table layout, which I find humongous. So I added Vigil to my Sinatra Status Board app and made a table with a more reasonable size.
