OSHI是Java的免费基于JNA的#xff08;本机#xff09;操作系统和硬件信息库。它不需要安装任何其他本机库#xff0c;并且旨在提供一种跨平台的实现来检索系统信息#xff0c;例如操作系统版本#xff0c;进程#xff0c;内存和CPU使用率#xff0c;磁盘和分区本机操作系统和硬件信息库。它不需要安装任何其他本机库并且旨在提供一种跨平台的实现来检索系统信息例如操作系统版本进程内存和CPU使用率磁盘和分区设备传感器等。
使用OSHI我们可以对应用程序进行监控可以对应用程序所在的服务器资源进行监控可以监控到很多的指标如下
1、计算机系统和固件底板 2、操作系统和版本/内部版本 3、物理核心和逻辑超线程CPU处理器组NUMA节点 4、系统和每个处理器的负载百分比和滴答计数器 5、CPU正常运行时间进程和线程 6、进程正常运行时间CPU内存使用率用户/组命令行 7、已使用/可用的物理和虚拟内存 8、挂载的文件系统类型可用空间和总空间 9、磁盘驱动器型号序列号大小和分区 10、网络接口IP带宽输入/输出 11、电池状态电量百分比剩余时间电量使用情况统计信息 12、连接的显示器带有EDID信息 13、USB设备 14、传感器温度风扇速度电压
