Introducing Simon 5!

Simon version 5 is now available. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.

Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and is a paid upgrade from Simon 4. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).

Read the Simon What's New page for details.

DNS check not working?

I've setup a DNS test, but it doesn't seem to work.
The triangle is gray, last change is n/a last failure never, next check counts down (I have it set to every 60 seconds.

I setup a ping monitor and it works fine and has a green triangle.

Have I missed something?

(for one dns test, I used the domain name with all default settings)

Re: DNS check not working?

A gray triangle indicates success, but no changes. The DNS service doesn't support change detection, so will always be gray until a failure occurs. That's also why the Last Change is "n/a", for not applicable.

By default Simon uses time-sensitive status icons, which are gray when successful but nothing has changed or failed, bright green when a change occurs, slowly fading back to gray over time, bright red when a failure occurs, and orange when it recovers from a failure, again slowly fading back to gray over time.

If you would prefer simple green = success, red = failure status icons, change the General Preference to "Use simple status icons". See the User Guide for more info.
