the you *need* to test this outside of the service itself, completly rely on a even from inside the service which signals all is fine is a broken design when it comes to monitoring - you can't ask the thing which you want to monitor if ot works as expectd "do you work as expected" - common sense
for our webservers a simple loop with a sleep checks if it responds with the expected content and if not calls "systemctl condrestart httpd" to not behave bad after a intended service stop
another method would be just send a SIGKILL to the process and use Restart=always RestartSec=1 would lead in systemd restarts it automatically
