# 排除传感器故障 以下资源描述了一些常见问题以及可用于分析和解决这些问题的技术。 Note `` 应被视为设备上的现有路径之一：`/etc/sensors/registry/registry/` 或 `/var/cache/sensors/registry/registry/`。 ## `ssc_sensor_info` 工具无法列出传感器 此错误表示解析传感器注册表失败，导致传感器无法使用 `ssc_sensor_info` 工具列出。执行以下操作来解决此错误： > > > Note > > > 验证用户模式下是否启用了文件的读写权限，组和其他模式下是否启用了只读权限。确保用户和组模式名称为 `system system`。 > > > 1. 确保 `/etc/sensors/sns_reg_config` 和 `/etc/sensors/config/json.lst`
