 ## 指标
 
-- `onvif_device_up`：1=可达，0=不可达（标签：instance, location, model, device_type）
-- `onvif_probe_duration_seconds`：探测耗时（秒）
+- `onvif_device_up`：1=可达，0=不可达  
+  - 标签：`instance`, `location`, `model`, `device_type`, `lat`, `lon`
+- `onvif_probe_duration_seconds`：探测耗时（秒）  
+  - 标签同上
 
 ## 配置
 
 - 从 **config/onvif-targets.json** 读取设备列表（与 `targets.csv` 中 onvif 行一致，由 `config/update-configs.sh` 生成）。
+  - 支持字段：`device_type`, `model`, `location`, `username`, `password`, `onvif_port`, `lat`, `lon`
 - 环境变量：`TARGETS_FILE`（默认 `/config/targets.json`）、`EXPORTER_PORT`（默认 9600）。
