  Host: prod-web-01  ·  Ubuntu 22.04 LTS  ·  Disk: root 94%  ·  Failed: nginx
  CPU: 8 cores  ·  Mem: 6.2 / 32 GB  ·  Uptime: 1h 14m

you › disk is full and nginx won't start. what's eating it?

ai  › Root is at 94%. Most likely nginx failed because it can't write logs.
      Let me check the biggest offenders under /var/log:

      du -h /var/log --max-depth=1 | sort -rh | head -5

      1.9G  /var/log/journal
      1.2G  /var/log/nginx

      journald is holding 1.9G. Safe to vacuum to 200M:

      journalctl --vacuum-size=200M  [Y/n]
