It's working now. It was quite long journey. The problem was journald-upload process couldn't read journal file. I had run with strace and it repeatedly said like this, (open /var/log/.../system.journal, PERMISSION DENIED). $ ls -l /var/log/journal/.../system.journal -rw-r-----+ 1 root systemd-journal 8388608 Apr 23 21:08 /var/log/journal/87dd383134bc4070950aa51ab6cbd793/system.journal I added systemd-journal-upload user to systemd-journal group then it's working. Next step would be automatically trigger syncing when vpn connection ready. 1. Power on laptop 2. openvpn service up 3. journal-remote up 4. send notification to vps 5. journal-upload up (vps) 6. syncing until vpn disconnect If I could just retry journald-upload periodically, It would be good enough. Any advice would be appreciated.
