# OpenTelemetry Collector (DaemonSet) — PaaSup 커스텀 오버라이드
# 차트: open-telemetry/opentelemetry-collector
# 배포: DaemonSet (모든 노드에서 파드 로그 수집)
# 릴리스명: otelcol
#
# 파이프라인 (로그 전용):
#   logs/demo01  : filelog → filter(namespace=demo01-*) → vlinsert AccountID 1
#   logs/demo02  : filelog → filter(namespace=demo02-*) → vlinsert AccountID 2
#   logs/platform: filelog → filter(나머지)              → vlinsert AccountID 0
#
# 참고: K8s 이벤트 수집은 Deployment 모드의 custom-values-events.yaml로 별도 배포.
