如何在Docker部署的Airflow中正常显示DAG Processor状态

我通过Docker运行Airflow 2.7.1集群，其余组件均运行正常，仅DAG Processor状态在集群页面显示为Unknown：

已完成以下排查步骤：

• 所有组件均处于健康运行状态，执行docker ps | grep airflow结果如下：

docker ps | grep airflow

• 已确认dag_processor_manager_log_location配置正确：

dag_processor_manager_log_location = /opt/airflow/logs/dag_processor_manager/dag_processor_manager.log

• 日志文件实际存在于指定路径，进入worker容器验证：

docker exec -it airflow_airflow-worker_1 bash
ls -l /opt/airflow/logs/dag_processor_manager
total 18444
-rw-rw-r-- 1 default root 18880639 Oct 10 06:15 dag_processor_manager.log

问题 #

1. 为何DAG Processor状态会显示为Unknown？
2. 需要如何配置集群才能让DAG Processor状态正常显示？
