Simon 5 is coming soon!
Simon version 5 is currently in beta testing. 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 will be a paid upgrade from Simon 4 after the beta. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
I'm sorry that Simon is misbehaving.
One thing that might be helpful is a hang log — if Simon hangs again, go to Activity Monitor (in /Application/Utilities), select Simon, and do a Sample of it while it's not responding. That'll show what is hanging it.
You could also look in the Console log to see if there are any Simon-related issues listed there (/Applications/Console).
What kinds of services do you have? Only Web (HTTP), or others? I plan on splitting the Web (HTTP) plugin out to a separate process in version 3.2, to address some hangs that some people have experienced with lots of tests overloading Simon.
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
Right now only Web (HTTP).
Thanks for the advice about the hangs/crashes, but the bigger issue is the false readings. I'll reload all my sites for now, but I'll have around 30 and that's too much to have to do regularly, especially as it's increasing regularly.
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
And if it's giving false positives, how do I know it's not giving false negatives?
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
The false failures would be due to timing out, possibly due to the OS's background thread hanging. That's the issue I'll be addressing in 3.2, so if that's what you're experiencing, a fix is coming. But with that issue, simply quitting and relaunching Simon fixes it, which doesn't sound exactly what you experienced. So a log may be helpful.
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
I've already eliminated all the old services and reloaded them anew, so the failure logs are clear. Is there a way to view logs for sites/services that are no longer being followed?
If it happens again, I'll send that on.
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
I meant the Console log (/Applications/Console). It might provide clues about what's going on. Probably wait to see if it occurs again.
Re: Simon shows ALL SITES DOWN (they're not) and Stop ...
The described behavior reminds me of my own issue with Simon 3.1.1 (German localization) which was due to the fact that all „Options“ times in the filter settings were reset to 0 seconds - which doesn’t give any test a chance to ever succeed.
David: Maybe this issue is not only inside the German localized NIBs but some kind of structural issue?

Ulf: I hope not, but it's worth investigating.
