说明:获取的数据是操作系统整体的资源占用情况,不是当前 java进程占用的资源
1. 获取系统CPU占用情况 :
import java.lang.management.ManagementFactory; import com.sun.management.OperatingSystemMXBean; private static OperatingSystemMXBean osmxb = (OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean(); public static int cpuLoad() { double cpuLoad = osmxb.getSystemCpuLoad(); int percentCpuLoad = (int) (cpuLoad * 100); return percentCpuLoad; }
注意:JDK必须是1.8及以上的
返回的值是CPU的百分比,取的是整数值
2. 获取系统内存占用情况
import java.lang.management.ManagementFactory; import com.sun.management.OperatingSystemMXBean; private static OperatingSystemMXBean osmxb = (OperatingSystemMXBean) ManagementFactory.getOperatingSystemMXBean(); public static int memoryLoad() { double totalvirtualMemory = osmxb.getTotalPhysicalMemorySize(); double freePhysicalMemorySize = osmxb.getFreePhysicalMemorySize(); double value = freePhysicalMemorySize/totalvirtualMemory; int percentMemoryLoad = (int) ((1-value)*100); return percentMemoryLoad; }
注意:JDK为1.6及以上版本
返回的值是内存的百分比,取的是整数值
