Both frontend and backend now write rotating log files to
/mnt/converter/logs/ (shared between host and LXC):
/mnt/converter/logs/vm-bench.log (frontend)
/mnt/converter/logs/vm-bench-backend.log (backend)
- RotatingFileHandler: 10 MB per file, 5 backups
- Console handler still writes to systemd journal
- Logs/ directory is gitignored and auto-created on startup
- Install script creates logs/ directory
Backend had zero logging. Frontend logs were fine (logging.basicConfig
in app.py). Now both services write structured logs to systemd journal:
journalctl -u vm-bench -f # frontend (LXC)
journalctl -u vm-bench-backend -f # backend (srv2)
{job_id} in f-strings was interpreted as Python variable instead
of FastAPI path parameter. Double braces {{job_id}} produce
literal {job_id} in the route string.
