08db3580a7 fix(monitoring): 修復 110 主機 CPU 高負載
Some checks are pending
CD Pipeline / build-and-deploy (push) Has started running
Details 
根因 1: cadvisor 持續掃描 overlay2 磁碟用量 (每次 1-4s × N 容器)
  → 加 --disable_metrics=disk,diskIO,tcp,udp,percpu,sched,process
  → --housekeeping_interval=30s --docker_only=true
  → CPU 從 239% 降到 <1%

根因 2: node_exporter scrape_timeout 預設 10s，高 load 下超時→broken pipe→瘋狂重試
  → 加 scrape_interval: 30s / scrape_timeout: 25s
  → CPU 從 48% 降到 0%

整體 load average: 20 → 9

5bd8a8a719 fix(monitoring): 補齊 blackbox-tcp scrape targets (11→15)
Some checks failed
CD Pipeline / build-and-deploy (push) Has been cancelled
Details 
SentryDown/HarborDown/SignOzDown 等告警引用的 instance 不在 scrape list
導致 absent metric = 0，告警持續 firing

新增缺少的 targets:
  192.168.0.125:6443/32334/32335 (K3s)
  192.168.0.110:9000/5000/3100 (Sentry/Harbor/Langfuse)
  192.168.0.188:3301/5432/6380/11434/8089 (SignOz/PG/Redis/Ollama/OpenClaw)

已在 110 主機 reload Prometheus，全部 15 targets UP

85d4857d1b fix(monitoring): RedisMemoryHigh 誤報 — max_bytes=0 除以零修正
Some checks are pending
CD Pipeline / build-and-deploy (push) Has started running
Details
Deploy Alert Rules / Deploy Prometheus Alert Rules (push) Successful in 37s
Details 
- 加入 redis_memory_max_bytes > 0 前置條件
- 防止 Redis 未設 maxmemory 時除以零產生 +Inf 永遠觸發
- 影響: alerts-unified.yml + database-alerts.yaml

3f339110dd fix(observability): 同步 .188 實際部署調整至 repo
Some checks failed
CD Pipeline / build-and-deploy (push) Has been cancelled
Details
E2E Health Check / e2e-health (push) Has been cancelled
Details 
與原始計畫的差異:

1. 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. ADR-053 驗收清單更新為實際結果

99be215e83 fix(monitoring): R1 Review 修正 — Blackbox DNS/PSA label/告警閾值 
Critical: Blackbox Exporter replacement 從 K8s DNS 改為主機 IP (192.168.0.188:9115)
Important: Descheduler namespace 顯式宣告 PSA restricted labels
Suggestion: failedJobsHistoryLimit 3→1, 新增 MinioDiskUsageCritical 5% 告警

41bf0681cf feat(observability): Phase O-2/O-3 OTEL Log管線 + Event Exporter + Remote Write 
O-2.1: OTEL Collector DaemonSet (filelog receiver)
  - 收集所有 K3s 節點 Pod stdout/stderr → SigNoz ClickHouse
  - CRI log parser (Go time layout for +08:00 timezone)
  - filter processor 排除 kube-system debug noise
  - observability namespace PSA privileged (log 目錄需 root)
  - 資源限制: 50m-200m CPU / 64-128Mi Memory

O-2.2: kubernetes-event-exporter
  - K8s Event → 結構化 JSON Log → SigNoz
  - Warning/Error 全量保留, Normal 過濾高頻事件
  - 解決: Event 預設僅保留 ~1hr 的致命盲區

O-3: Prometheus remote_write 配置模板
  - 白名單: ~50 關鍵 metric series (node/container/kube/api/db)
  - 目標: 90 天長期儲存於 SigNoz ClickHouse

已部署驗證: 3 Pod Running, 0 error, filelog 正常監控所有 namespace

6ce82ff883 fix(k3s): Phase O-1 基礎設施修復 — Descheduler + MinIO/Kali 監控 
O-1.1: Descheduler securityContext 修復 (PodSecurity restricted 合規)
  - 新增 pod securityContext (runAsNonRoot, runAsUser:65534, seccompProfile)
  - 新增 container securityContext (allowPrivilegeEscalation:false, drop ALL)
  - 補齊 RBAC: namespaces + replicasets list 權限
  - 已部署驗證: CronJob 成功執行 (Status: Completed)

O-1.3: MinIO Prometheus scrape 配置 + 告警規則
O-1.4: Kali Blackbox TCP probe + 告警規則
  - MinioDown, MinioDiskUsageHigh, MinioOfflineDisk
  - KaliScannerDown

待手動部署: Prometheus config → .188, kubectl kubeconfig → 120/121
