收藏资源简介:
该数据集包含从越南Biên Hòa, Đồng Nai农业农场部署的Raspberry Pi 5 (8 GB)边缘计算节点收集的9,409条系统性能记录。设备管理了10个同时进行的IP摄像头流,通过FFmpeg进行实时RTSP→RTMP转码,由10个独立的systemd服务协调。数据在32天内(2026年3月23日至2026年4月25日)以5分钟间隔连续收集,无间断。每条记录包含18个系统级指标,涵盖CPU、内存、温度、网络和磁盘性能。关键发现包括:Pi 5在使用FFmpeg -c:v copy直通策略时,平均CPU使用率仅为4.23%;整个32天期间零重启、零交换使用、零热节流事件;核心温度与环境温度条件(与网络吞吐量的相关性r≈0.65)强相关,而非CPU负载;ISP可靠性为97.5%(零丢包),平均延迟为53毫秒,足以支持连续直播。所有敏感信息(摄像头IP、凭证、RTMP流密钥、序列号)在公开发布前已匿名化。
This dataset contains 9,409 system performance records collected from a Raspberry Pi 5 (8 GB) deployed as an edge computing node at an agricultural farm in Biên Hòa, Đồng Nai, Vietnam. The device managed 10 simultaneous IP camera streams, performing real-time RTSP→RTMP transcoding via FFmpeg, orchestrated by 10 independent systemd services. Data was collected continuously for 32 days (23/03/2026 – 25/04/2026) at 5-minute intervals with no gaps. Each record contains 18 system-level metrics covering CPU, memory, thermal, network, and disk performance. Key findings include: Pi 5 sustained 10-channel live streaming at mean CPU usage of only 4.23% using FFmpeg -c:v copy passthrough strategy; Zero reboots, zero swap usage, zero thermal throttling events across the entire 32-day period; Core temperature strongly correlated with ambient thermal conditions (r ≈ 0.65 with network throughput), not CPU load; ISP reliability of 97.5% (zero packet loss) with mean latency of 53 ms — sufficient for continuous live streaming. All sensitive information (camera IPs, credentials, RTMP stream keys, serial numbers) has been anonymized before public release.
