MinIO Bearer Token 認證 - 原計畫: MINIO_PROMETHEUS_AUTH_TYPE=public (此版本不支援) - 實際: mc admin prometheus generate 產生 Bearer Token - 更新: prometheus-config-phase-o.yaml 加入 bearer_token 2. remote_write 廢棄 → OTEL Collector Prometheus scrape - 原計畫: Prometheus remote_write → SigNoz OTEL /api/v1/write - 實際: SigNoz OTEL Collector 不支援 Prometheus remote_write 格式 (404) - 改用: OTEL Collector prometheus receiver 直接 scrape node-exporter + kube-state-metrics - 新增: ops/signoz/otel-collector-config-phase-o.yaml (版本控管副本) 3.
