scouter 설정

내가 생각하는 2025-03월 기준 최적인 scouter 구성

각 컴포넌트 버전

• Collector Server : 2.20.0

• agent.host: 2.7.1

  → 2.7.1 이후 버전부터 디스크 데이터가 잘 표시되지 않는 현상이 있어 2.7.1로 결정함

• agent.java: 2.20.0
• webapp: 2.20.0

Scouter collection server conf

log_service_handler_list=true
net_bind=0.0.0.0

# 저장소 자동 삭제 동작 여부
mgr_purge_enabled=true

#프로파일 데이터를 자동으로 지우는 디스크 사용량(%)
mgr_purge_disk_usage_pct=80

#프로파일 데이터가 자동으로 지워지기 전에 유지되는 날짜 수
mgr_purge_profile_keep_days=10

#xlog 정의 데이터가 자동으로 지워지기 전에 유지되는 날짜 수
mgr_purge_xlog_keep_days=30

#각종 카운터(선 그래프의 값)가 자동으로 지워지기 전에 유지되는 날짜 수
mgr_purge_counter_keep_days=70
