聊聊GarbageCollectionNotificationInfo
序
本文主要研究一下GarbageCollectionNotificationInfo
CompositeData
java.management/javax/management/openmbean/CompositeData.java
public interface CompositeData {
public CompositeType getCompositeType();
public Object get(String key) ;
public Object[] getAll(String[] keys) ;
public boolean containsKey(String key) ;
public boolean containsValue(Object value) ;
public Collection<?> values() ;
public boolean equals(Object obj) ;
public int hashCode() ;
public String toString() ;
}
CompositeData接口定义了getCompositeType、get、getAll、containsKey、containsValue、values、equals、hashCode、toString方法
CompositeDataView
java.management/javax/management/openmbean/CompositeDataView.java
public interface CompositeDataView {
public CompositeData toCompositeData(CompositeType ct);
}
CompositeDataView接口定义了toCompositeData方法，用于将数据转换为CompositeData
GcInfo
jdk.management/com/sun/management/GcInfo.java
public class GcInfo implements CompositeData, CompositeDataView {
private final long index;
private final long startTime;
private final long endTime;
private final Map<String, MemoryUsage> usageBeforeGc;
private final Map<String, MemoryUsage> usageAfterGc;
private final Object[] extAttributes;
private final CompositeData cdata;
private final GcInfoBuilder builder;
private GcInfo(GcInfoBuilder builder,
long index, long startTime, long endTime,
MemoryUsage[] muBeforeGc,
MemoryUsage[] muAfterGc,
Object[] extAttributes) {
this.builder = builder;
this.index = index;
this.startTime = startTime;
this.endTime = endTime;
String[] poolNames = builder.getPoolNames();
this.usageBeforeGc = new HashMap<String, MemoryUsage>(poolNames.length);
this.usageAfterGc = new HashMap<String, MemoryUsage>(poolNames.length);
for (int i = 0; i < poolNames.length; i++) {
this.usageBeforeGc.put(poolNames[i], muBeforeGc[i]);
this.usageAfterGc.put(poolNames[i], muAfterGc[i]);
}
this.extAttributes = extAttributes;
this.cdata = new GcInfoCompositeData(this, builder, extAttributes);
}
private GcInfo(CompositeData cd) {
GcInfoCompositeData.validateCompositeData(cd);
this.index = GcInfoCompositeData.getId(cd);
this.startTime = GcInfoCompositeData.getStartTime(cd);
this.endTime = GcInfoCompositeData.getEndTime(cd);
this.usageBeforeGc = GcInfoCompositeData.getMemoryUsageBeforeGc(cd);
this.usageAfterGc = GcInfoCompositeData.getMemoryUsageAfterGc(cd);
this.extAttributes = null;
this.builder = null;
this.cdata = cd;
}
public long getId() {
return index;
}
public long getStartTime() {
return startTime;
}
public long getEndTime() {
return endTime;
}
public long getDuration() {
return endTime - startTime;
}
public Map<String, MemoryUsage> getMemoryUsageBeforeGc() {
return Collections.unmodifiableMap(usageBeforeGc);
}
public Map<String, MemoryUsage> getMemoryUsageAfterGc() {
return Collections.unmodifiableMap(usageAfterGc);
}
public static GcInfo from(CompositeData cd) {
if (cd == null) {
return null;
}
if (cd instanceof GcInfoCompositeData) {
return ((GcInfoCompositeData) cd).getGcInfo();
} else {
return new GcInfo(cd);
}
}
// Implementation of the CompositeData interface
public boolean containsKey(String key) {
return cdata.containsKey(key);
}
public boolean containsValue(Object value) {
return cdata.containsValue(value);
}
public boolean equals(Object obj) {
return cdata.equals(obj);
}
public Object get(String key) {
return cdata.get(key);
}
public Object[] getAll(String[] keys) {
return cdata.getAll(keys);
}
public CompositeType getCompositeType() {
return cdata.getCompositeType();
}
public int hashCode() {
return cdata.hashCode();
}
public String toString() {
return cdata.toString();
}
public Collection<?> values() {
return cdata.values();
}
public CompositeData toCompositeData(CompositeType ct) {
return cdata;
}
}
GcInfo实现了CompositeData及CompositeDataView接口，它主要有index、startTime、endTime、usageBeforeGc、usageAfterGc、extAttributes、cdata这几个属性
GarbageCollectionNotificationInfo
jdk.management/com/sun/management/GarbageCollectionNotificationInfo.java
public class GarbageCollectionNotificationInfo implements CompositeDataView {
private final String gcName;
private final String gcAction;
private final String gcCause;
private final GcInfo gcInfo;
private final CompositeData cdata;
public static final String GARBAGE_COLLECTION_NOTIFICATION =
"com.sun.management.gc.notification";
public GarbageCollectionNotificationInfo(String gcName,
String gcAction,
String gcCause,
GcInfo gcInfo) {
if (gcName == null) {
throw new NullPointerException("Null gcName");
}
if (gcAction == null) {
throw new NullPointerException("Null gcAction");
}
if (gcCause == null) {
throw new NullPointerException("Null gcCause");
}
this.gcName = gcName;
this.gcAction = gcAction;
this.gcCause = gcCause;
this.gcInfo = gcInfo;
this.cdata = new GarbageCollectionNotifInfoCompositeData(this);
}
GarbageCollectionNotificationInfo(CompositeData cd) {
GarbageCollectionNotifInfoCompositeData.validateCompositeData(cd);
this.gcName = GarbageCollectionNotifInfoCompositeData.getGcName(cd);
this.gcAction = GarbageCollectionNotifInfoCompositeData.getGcAction(cd);
this.gcCause = GarbageCollectionNotifInfoCompositeData.getGcCause(cd);
this.gcInfo = GarbageCollectionNotifInfoCompositeData.getGcInfo(cd);
this.cdata = cd;
}
public String getGcName() {
return gcName;
}
public String getGcAction() {
return gcAction;
}
public String getGcCause() {
return gcCause;
}
public GcInfo getGcInfo() {
return gcInfo;
}
public static GarbageCollectionNotificationInfo from(CompositeData cd) {
if (cd == null) {
return null;
}
if (cd instanceof GarbageCollectionNotifInfoCompositeData) {
return ((GarbageCollectionNotifInfoCompositeData) cd).getGarbageCollectionNotifInfo();
} else {
return new GarbageCollectionNotificationInfo(cd);
}
}
public CompositeData toCompositeData(CompositeType ct) {
return cdata;
}
}
GarbageCollectionNotificationInfo实现了CompositeDataView接口的toCompositeData方法，它主要有gcName、gcAction、gcCause、gcInfo、cdata这几个属性，toCompositeData返回的是cdata

小结
GarbageCollectorMXBean在完成一个次垃圾收集的action的时候会发射一个A garbage collection notification，它返回的是GarbageCollectionNotificationInfo
GarbageCollectionNotificationInfo实现了CompositeDataView接口的toCompositeData方法，它主要有gcName、gcAction、gcCause、gcInfo、cdata这几个属性，toCompositeData返回的是cdata；GcInfo实现了CompositeData及CompositeDataView接口，它主要有index、startTime、endTime、usageBeforeGc、usageAfterGc、extAttributes、cdata这几个属性
可以发现无论是使用G1 GC、ZGC还是Shenandoah GC，都能从对应的GarbageCollectionNotificationInfo获取相关信息，只是不同的垃圾收集器除了gcName不一样外，它们的usageBeforeGc及usageAfterGc(Map<String, MemoryUsage>)中的key也不尽相同
