-라즈베리파이는 `rsyslog`와 `rsyslog-gnutls`로 로컬 journal/syslog를 시놀로지 Log Center에 TCP/TLS 6514로 보냅니다. 전송 대상은 `chaegeon.com:6514`이며, 네트워크가 끊기면 `/var/spool/rsyslog/control_synology_fwd*` 큐에 남았다가 재시도합니다.

-시놀로지는 DSM `syslog-ng`에서 라즈베리파이 `121.157.202.229:6514`로 TCP/TLS syslog를 보냅니다. 라즈베리파이 수신 로그는 `/var/log/remote/synology/*.log`에 저장하고 `/etc/logrotate.d/control-remote-syslog`가 매일 회전합니다. Control 진단 패널의 시놀로지 로그 뷰어는 `/var/log/remote/synology/chaegeon.log` 최근 500줄을 최신순으로 보여주며, WebSocket 또는 HTTP fallback으로 1초마다 갱신합니다. 사용자가 로그 영역을 스크롤하는 동안에는 자동 갱신을 잠깐 멈춰 화면 위치가 튀지 않게 합니다.
+## 로그 보존

 커널 패닉이나 강제 재부팅 분석을 위해 `systemd-journald`는 `/var/log/journal`에 영구 저장합니다. `dtoverlay=ramoops` 기반 pstore는 부팅 직후 `control-pstore-collect.service`가 `/var/log/pstore`로 복사합니다. 현재 pstore에 남은 크래시 조각이 없으면 이 서비스는 조건 불충족으로 `inactive`일 수 있으며 정상입니다.
