SystemInformationRVC4
SystemInformationRVC4
SystemInformationRVC4 扩展了 SystemInformation，其中包含特定于基于 RVC4 平台的 OAK 设备的遥测数据。当应用程序在 RVC4 硬件上运行时，SystemLogger 节点会发布此信息，公开 CPU 平均值、进程级别的 CPU 和内存使用情况，以及 RVC4 子系统的扩展温度传感器。消息的使用方式与 SystemInformation 完全相同：订阅 SystemLogger.out，或通过 MessageGroup 将数据转发到主机。在运行时，您可以检查 chipTemperature、ddrMemoryUsage、cpuAvgUsage 以及进程级别的使用情况字段，以监控设备健康状况。示例
