<br>
Yes, this would work.<br>
<br>
<br>
Solution 1:<br>
My service (written Python) uses the journald API.<br>
Disadvantage: My script can't be run under a different environment (without journald)<br>
<br>
<br>
<br>
Solution 2:<br>
I let my service write json to stdout and a wrapper collects these lines and the wrapper uses the journald API.<br>
Disadvantage: Systemd is monitoring the wrapper, not the real service. Signal handling for stopping and restarting<br>
is not direct from systemd to service.<br>
<br>
<br>
The perfect solution is not found yet.<br>
