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: availability reports for SLA's
Thanks, I'm glad you like Simon.
The only way to do an extended period report at present is to ensure the number of check log entries kept is enough to cover the desired time period. The logging preferences allow specifying the number of entries; they default to 100, but can be more. Then you'd need to modify the report template to output the desired number of lines: the template specifies how many to display.
The Recent Checks section of the report should now include indication of when the internet connection is offline.
I'm interested in suggestions on how the reporting can be improved, so if you have any specific suggestions on what you'd like it to do beyond the above, I'm all ears.
