+# chat-deploy 可观测性组件部署配置
+# 用于向 itom-platform 可观测中心推送日志和指标
+#
+# 使用方法：
+#   1. 复制 config.env.example 为 config.env 并修改配置
+#   2. 启动服务：docker compose --env-file config.env -f docker-compose-observability.yaml up -d
+#   3. 如需启用指标采集：docker compose --env-file config.env -f docker-compose-observability.yaml --profile metrics up -d
