TraceManager

public class TraceManager extends Object implements TraceDestination
Provides an implementation of the {@link com.sun.jmx.trace.TraceDestination} interface which uses the J2SE logging API.

Note that this implementation can be used only with J2SE version 1.4 or higher.

All {@link Logger}s are contained in the javax.management namespace, which corresponds to the name of the root package hosting all public JMX interfaces. For each log type defined in {@link TraceTags}, we use a dedicated {@link Logger} with the same name under javax.management.

The table below shows the list of {@link Logger} objects used in this implementation and their corresponding category of activity.

Logger Name JMX log type Information logged
javax.management.mbeanserver {@link TraceTags#INFO_MBEANSERVER} Information about the MBean Server
com.sun.jmx.snmp.daemon {@link TraceTags#INFO_ADAPTOR_SNMP} Information about the SNMP Adaptor
com.sun.jmx.snmp {@link TraceTags#INFO_SNMP} Information about SNMP
javax.management.mlet {@link TraceTags#INFO_MLET} Information from an MLet service
javax.management.monitor {@link TraceTags#INFO_MONITOR} Information from a monitor
javax.management.timer {@link TraceTags#INFO_TIMER} Information from a timer
javax.management.notification {@link TraceTags#INFO_NOTIFICATION} Information from the notification mechanism
javax.management.relation {@link TraceTags#INFO_RELATION} Information from the Relation Service
javax.management.modelmbean {@link TraceTags#INFO_MODELMBEAN} Information from the Model MBean components
javax.management.misc {@link TraceTags#INFO_MISC} Information sent from any other class


The mapping for the JMX log levels is the following:

JMX log level J2SE logging API log level
{@link TraceTags#LEVEL_DEBUG}
{@link Level#FINEST}
{@link TraceTags#LEVEL_TRACE}
{@link Level#FINER}
{@link TraceTags#LEVEL_ERROR}
{@link Level#SEVERE}

public voidreset()
Not implemented, as the control over log levels and output handler is deferred to the J2SE logging API.

public booleansend(int level, int type, java.lang.String className, java.lang.String methodName, java.lang.String info)
Note that the provided log type and log level have to be part of the enumerated values defined in class {@link TraceTags}. Otherwise, nothing is logged.

see
TraceDestination#send(int, int, String, String, String)

Note that the provided log type and log level have to be part of the enumerated values defined in class {@link TraceTags}. Otherwise, nothing is logged.

see
TraceDestination#send(int, int, String, String, Throwable)

      if (isSelected(level, type)) {
