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).

HTTP Status Codes

I've been using Simon for a while. It's a handy app. But I've come to need the ability to be able to detect specific HTTP status codes. For example, I'd like to be able to count a server error 500 as as a failure.

I've looked, but there doesn't seem to be any way to do this. Am I just missing it?

Thanks for your help.

Re: HTTP Status Codes

If you use the Smart Change Detection feature with header mode (instead of source), you should be able to look at the status code in the header.

In a future version, possibly 2.6, I want to extend this to a more general-purpose filter feature, which could have more intuitive access to the status codes.

Yeah, I thought about using

Yeah, I thought about using that, but if I use it to check for a 500, it'll track as a "change" rather than a "failure", right?

Re: Yeah, I thought about

Actually if you told it to check for 500 in the headers, you'd probably get a failure for everything except a 500.

More sophisticated logic has to be done in a service or notifier currently... which is why I want to add the filter feature, as an analysis layer between a service and the notifiers, so you can use a standard service like Web but reinterpret the output.
