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: Is App running on a remote server
You can add a similar service to that by writing a script. You could SSH into another machine, then use ps or another tool to check for the app.
I tried to create a Script-based service with the following script:
ssh {Machine Name} << EOF{Password}
ps ax | grep -v grep | grep {Application}
EOF
But it fails with the error:
Pseudo-terminal will not be allocated because stdin is not a terminal.This happens if I do the equivalent in the Terminal, too, so it isn't a Simon-specific issue.
Perhaps someone else can clarify a way to send actions to SSH?
