示例1: getProcessCpuLoad
import javax.management.MBeanServerConnection; //导入方法依赖的package包/类
public static double getProcessCpuLoad(MBeanServerConnection mbs)
throws MalformedObjectNameException, NullPointerException, InstanceNotFoundException,
ReflectionException, IOException {
ObjectName name = ObjectName.getInstance("java.lang:type=OperatingSystem");
AttributeList list = mbs.getAttributes(name, new String[]{"ProcessCpuLoad"});
if (list.isEmpty()) {
return 0.0;
}
Attribute att = (Attribute) list.get(0);
Double value = (Double) att.getValue();
// usually takes a couple of seconds before we get real values
if (value == -1.0) {
return 0.0;
}
// returns a percentage value with 1 decimal point precision
return ((int) (value * 1000) / 10.0);
}
示例2: getMeterMetric
import javax.management.MBeanServerConnection; //导入方法依赖的package包/类
private MeterMetric getMeterMetric(MBeanServerConnection mbsc, ObjectName objectName) {
String[] attributes = {"Count", "MeanRate", "OneMinuteRate", "FiveMinuteRate", "FifteenMinuteRate"};
AttributeList attributeList = null;

} catch (Exception e) {
LOG.warn("getMeterMetric failed! " + e.getMessage());
return new MeterMetric(0L, 0D, 0D, 0D, 0D);
}
return new MeterMetric(getLongValue(attributeList, attributes[0]), getDoubleValue(attributeList, attributes[1]),
getDoubleValue(attributeList, attributes[2]), getDoubleValue(attributeList, attributes[3]),
