Interface GarbageCollectionMonitorMBean

All Superinterfaces:

SelfEmailingMBean

public interface GarbageCollectionMonitorMBean
extends SelfEmailingMBean

Provides simple interface to monitor percentage of time recently spent in garbage collection

The MBeans built into Java 5 provide the necessary statistics, but not notifications, nor the necessary derived statistic -- garbage collection as a percentage of overall time.

Supported API: true

Extendable: true

Field Summary

static String	GC_THRESHOLD_EXCEEDED_INITIAL_NOTIF_TYPE Type of notification produced when PercentTimeSpentInGCThreshold is initially exceeded Supported API: true
static String	GC_THRESHOLD_EXCEEDED_NO_LONGER_NOTIF_TYPE Type of notification produced when PercentTimeSpentInGCThreshold is no longer exceeded Supported API: true
static String	GC_THRESHOLD_EXCEEDED_STILL_NOTIF_TYPE Type of notification produced when PercentTimeSpentInGCThreshold is still exceeded Supported API: true

Method Summary

double	getPercentTimeSpentInGCThreshold() Threshold percentage of time spent in GC during an interval above which a notification will be issued Supported API: true
int	getRecentIntervalSeconds() Duration of recent time interval in seconds Supported API: true
double	getRecentPercentTimeSpentInGC() Percentage of time spent performing garbage collection during recent time interval Supported API: true
void	setPercentTimeSpentInGCThreshold(double percentTimeSpentInGCThreshold) Threshold percentage of time spent in GC during an interval above which a notification will be issued Supported API: true
void	setRecentIntervalSeconds(int recentIntervalSeconds) Duration of recent time interval in seconds Supported API: true
