# openclaw-watchdog.sh — OpenClaw Gateway 헬스체크 + 자동 재시작
# crontab에 등록하여 1분마다 실행
#
# Usage:
# */1 * * * * /PROJECT/0325120031_A/ghong/taketimes/llm-bang/scripts/openclaw-watchdog.sh
#
# 변경이력:
# 2026-03-01 네트워크 체크를 ICMP→HTTP로 변경 (ICMP 차단 환경 대응)
# 다중 엔드포인트 fallback, 게이트웨이 HTTP 응답 체크 추가
# setsid 분리 실행, 상세 로깅 강화
