获取系统cpu信息
=========
直接使用oshi的系统api
JSONObject cpuInfo = new JSONObject();
CentralProcessor processor = hardware.getProcessor();
// CPU信息
long[] prevTicks = processor.getSystemCpuLoadTicks();
Util.sleep(OSHI_WAIT_SECOND);
long[] ticks = processor.getSystemCpuLoadTicks();
long nice = ticks[CentralProcessor.TickType.NICE.getIndex()] - prevTicks[CentralProcessor.TickType.NICE.getIndex()];
long irq = ticks[CentralProcessor.TickType.IRQ.getIndex()] - prevTicks[CentralProcessor.TickType.IRQ.getIndex()];
long softirq = ticks[CentralProcessor.TickType.SOFTIRQ.getIndex()] - prevTicks[CentralProcessor.TickType.SOFTIRQ.getIndex()];
long steal = ticks[CentralProcessor.TickType.STEAL.getIndex()] - prevTicks[CentralProcessor.TickType.STEAL.getIndex()];
long cSys = ticks[CentralProcessor.TickType.SYSTEM.getIndex()] - prevTicks[CentralProcessor.TickType.SYSTEM.getIndex()];
long user = ticks[CentralProcessor.TickType.USER.getIndex()] - prevTicks[CentralProcessor.TickType.USER.getIndex()];
long iowait = ticks[CentralProcessor.TickType.IOWAIT.getIndex()] - prevTicks[CentralProcessor.TickType.IOWAIT.getIndex()];
long idle = ticks[CentralProcessor.TickType.IDLE.getIndex()] - prevTicks[CentralProcessor.TickType.IDLE.getIndex()];
long totalCpu = user + nice + cSys + idle + iowait + irq + softirq + steal;
//cpu核数
cpuInfo.put(“cpuNum”, processor.getLogicalProcessorCount());
//cpu系统使用率
cpuInfo.put(“cSys”, new DecimalFormat(“#.##%”).format(cSys * 1.0 / totalCpu));
//cpu用户使用率
cpuInfo.put(“user”, new DecimalFormat(“#.##%”).format(user * 1.0 / totalCpu));
//cpu当前等待率
cpuInfo.put(“iowait”, new DecimalFormat(“#.##%”).format(iowait * 1.0 / totalCpu));
//cpu当前使用率
cpuInfo.put(“idle”, new DecimalFormat(“#.##%”).format(1.0 - (idle * 1.0 / totalCpu)));
System.out.println(cpuInfo);
