+### Job Worker 監控 (2026-03-25 新增)
+
+**Worker 服務狀態檢查**:
+```bash
+# 檢查 Worker 程序
+ps aux | grep momentry
+
+# 查看 Worker 日誌
+tail -f /Users/accusys/momentry/log/worker.log
+```
+
+**monitor_jobs 狀態查詢**:
+```bash
+# 查看待處理工作
+psql -U accusys -d momentry -c "SELECT * FROM monitor_jobs WHERE status = 'pending';"
+
+# 查看執行中工作
+psql -U accusys -d momentry -c "SELECT * FROM monitor_jobs WHERE status = 'running';"
+
+# 查看失敗工作
+psql -U accusys -d momentry -c "SELECT * FROM monitor_jobs WHERE status = 'failed';"
+```
+
+**processor_results 狀態查詢**:
+```bash
+# 查看特定工作的處理器狀態
+psql -U accusys -d momentry -c "
+SELECT pr.*, mj.uuid 
+FROM processor_results pr 
+JOIN monitor_jobs mj ON pr.job_id = mj.id 
+WHERE mj.uuid = 'a1b10138a6bbb0cd';
+"
+
+# 查看所有失敗的處理器
+psql -U accusys -d momentry -c "
+SELECT pr.processor, COUNT(*) as failures 
+FROM processor_results pr 
+WHERE pr.status = 'failed' 
+GROUP BY pr.processor;
+"
+```
+
+**Redis 工作狀態**:
+```bash
+# 查看活躍工作
+redis-cli SMEMBERS momentry:jobs:active
+
+# 查看工作詳情
+redis-cli HGETALL momentry:job:{uuid}
+```
