Salmon is a Linux monitoring tool consisting of a Go daemon (salmon) that checks systemd services and custom exec commands, and a Rust+Slint desktop client (salmon-watch) that aggregates incidents from local and remote machines via WebSocket/SSH tunnels, showing a tray icon with desktop alerts. It's interesting because it combines systemd health monitoring with arbitrary shell-based checks into a single unified tray indicator, addressing the common problem of silent service failures on both desktops and personal servers.

Target audience: Linux desktop users, self-hosters, sysadmins, devops
