public interface LogMBean

extends CommonLogMBean

Configures the threshold severity level and filter settings for logging output.

Specifies whether the server logging is based on a Log4j implementation or the default Java Logging APIs.

Redirects the JVM stdout and stderr output to the registered log destinations.

getLogFileFilter

A filter configuration defines simple filtering rules to limit the volume of log messages written to the log file.

Returns:

The LogFilterMBean configuration for the log file.

Since:

9.0.0.0

setLogFileFilter

void setLogFileFilter(LogFilterMBean filter)

Sets the value of the LogFileFilter attribute.

Parameters:

filter - The filter configuration for filtering messages being written to the log file.

See Also:

LogMBean.getLogFileFilter()

getStdoutFilter

LogFilterMBean getStdoutFilter()

The filter configuration for log events being sent to the standard out.

Returns:

The LogFilterMBean configuration for stdout.

Since:

9.0.0.0

setStdoutFilter

void setStdoutFilter(LogFilterMBean filter)

Sets the value of the StdoutFilter attribute.

filter - The filter configuration for filtering messages being written to the stdout.

See Also:

LogMBean.getStdoutFilter()

getDomainLogBroadcastSeverity

String getDomainLogBroadcastSeverity()

The minimum severity of log messages going to the domain log from this server's log broadcaster. Messages with a lower severity than the specified value will not be published to the domain log.

Since:

9.0.0.0

setDomainLogBroadcastSeverity

void setDomainLogBroadcastSeverity(String severity)

getDomainLogBroadcastFilter

LogFilterMBean getDomainLogBroadcastFilter()

The filter configuration for log events being sent to the domain log.

Returns:

The LogFilterMBean configuration for broadcast to the domain log.

Since:

9.0.0.0

setDomainLogBroadcastFilter

void setDomainLogBroadcastFilter(LogFilterMBean filter)

Sets the filtering criteria for log events going to the domain log.

Parameters:

filter - The filter configuration for filtering messages being broadcast to the domain log.

getMemoryBufferSeverity

String getMemoryBufferSeverity()

Deprecated. 12.1.3.0

The minimum severity of log messages going to the memory buffer of recent log events. Messages with a lower severity than the specified value will not be cached in the buffer.

Since:

9.0.0.0

setMemoryBufferSeverity

void setMemoryBufferSeverity(String severity)

Deprecated. 12.1.3.0

Parameters:

severity -

getMemoryBufferFilter

LogFilterMBean getMemoryBufferFilter()

Deprecated. 12.1.3.0

The filter configuration for messages that are stored in the log memory buffer. By default, all log messages are cached.

Since:

9.0.0.0

setMemoryBufferFilter

void setMemoryBufferFilter(LogFilterMBean filter)

Deprecated. 12.1.3.0

Parameters:

filter -

getMemoryBufferSize

int getMemoryBufferSize()

Deprecated. 12.1.3.0

The size of the memory buffer that holds the last n log records. This is used to support viewing the most recent log record entries (tail viewing) from the WebLogic Administration Console.

Since:

9.0.0.0

setMemoryBufferSize

void setMemoryBufferSize(int size)

Deprecated. 12.1.3.0

Parameters:

size -

isLog4jLoggingEnabled

boolean isLog4jLoggingEnabled()

Deprecated. 12.1.3.0

Specifies whether the server logging is based on a Log4j implementation. By default, WebLogic logging uses an implementation based on the Java Logging APIs which are part of the JDK.

Applications that use the WebLogic Message Catalog framework or the NonCatalogLogger will not be affected by the underlying Logging implementation.

Since:

9.0.0.0

setLog4jLoggingEnabled

void setLog4jLoggingEnabled(boolean enableLog4j)

Deprecated. 12.1.3.0

Sets the value of the Log4jLoggingEnabled attribute.

See Also:

LogMBean.isLog4jLoggingEnabled()

isRedirectStdoutToServerLogEnabled

boolean isRedirectStdoutToServerLogEnabled()

Specifies whether the stdout of the JVM in which a WebLogic Server instance runs is redirected to the WebLogic logging system. When this attribute is enabled, the stdout content is published to all the registered log destinations, such as the server terminal console and log file.

Note that JVM messages are redirected asynchronously. In the event of an overload situation, these messages may be dropped. As a best practice, Oracle recommends using one of the supported logging APIs instead.

Since:

9.0.0.0

setRedirectStdoutToServerLogEnabled

void setRedirectStdoutToServerLogEnabled(boolean captureStdout)

isRedirectStderrToServerLogEnabled

boolean isRedirectStderrToServerLogEnabled()

Specifies whether the stderr of the JVM in which a WebLogic Server instance runs is redirected to the WebLogic Logging system. When this attribute is enabled, the stderr content is published to all the registered log destinations, such as the server terminal console and log file.

Note that JVM messages are redirected asynchronously. In the event of an overload situation, these messages may be dropped. As a best practice, Oracle recommends using one of the supported logging APIs instead.

Since:

9.0.0.0

setRedirectStderrToServerLogEnabled

void setRedirectStderrToServerLogEnabled(boolean captureStderr)

getDomainLogBroadcasterBufferSize

int getDomainLogBroadcasterBufferSize()

Broadcasts log messages to the domain log in batch mode.

The size of the buffer for log messages that are sent to the domain log. The buffer is maintained on the Managed Server and is broadcasted to the domain log when it is full.

If you notice performance issues due to a high rate of log messages being generated, set this value higher. This will cause the buffer to be broadcasted less frequently from the Managed Server to the domain log. In production environments, it is not recommended to set the buffer size lower than the production default of 10.

Since:

9.0.0.0

setDomainLogBroadcasterBufferSize

void setDomainLogBroadcasterBufferSize(int bufferSize)

Sets the size of the log message buffer for broadcasting to the domain log.

Parameters:

bufferSize -

isServerLoggingBridgeUseParentLoggersEnabled

boolean isServerLoggingBridgeUseParentLoggersEnabled()

Deprecated. 12.1.3.0

Specifies whether application log messages are propagated to the parent node in the Logger tree or to the WebLogic Server log by means of the Logging Bridge. By default, this attribute is disabled, which results in application log messages being propagated to the WebLogic Server log.

Note the following behavior:

• If WebLogic Server is configured to be based upon the the Java Logging API (the default), the Logging Bridge is made available as a java.util.logging.Handler object.
• If WebLogic Server is configured to be based upon a Log4j implementation, the Logging Bridge is made available as a org.apache.log4j.Appender object.
• If the ServerLoggingBridgeUseParentLoggersEnabled is disabled, applications that use either the Java Logging API or Log4j have their log messages redirected by the Logging Bridge to the WebLogic Server log.
• If the ServerLoggingBridgeUseParentLoggersEnabled is enabled, applications that use the Java Logging API have their log messages propagated to the parent node in the global Java Logging Logger tree.
• If the ServerLoggingBridgeUseParentLoggersEnabled is enabled, applications that use Log4j have their log messages propagated to the parent node in the Log4j Logger tree.

setServerLoggingBridgeUseParentLoggersEnabled

void setServerLoggingBridgeUseParentLoggersEnabled(boolean value)

Deprecated. 12.1.3.0

Parameters:

value -

getPlatformLoggerLevels

Properties getPlatformLoggerLevels()

Specifies the platform logger and the associated level names set through the WebLogic Server configuration.

Note the following behavior:

• The configuration is applicable for java.util.logging.Logger instances in the JDK's default global LogManager.
• WebLogic Server loggers are configured in terms of weblogic.logging.Severities through the LoggerSeverities attribute. These loggers are not available in the JDK's default global LogManager.

Since:

12.1.3.0

CommonLogMBean.getLoggerSeverityProperties()

setPlatformLoggerLevels

void setPlatformLoggerLevels(Properties props)

setServerLoggingBridgeAtRootLoggerEnabled

void setServerLoggingBridgeAtRootLoggerEnabled(boolean value)

isLogMonitoringEnabled

boolean isLogMonitoringEnabled()

Enable or disable log monitoring.

getLogMonitoringIntervalSecs

int getLogMonitoringIntervalSecs()

Timer interval in seconds to check the counts of messages logged during the interval.

int getLogMonitoringThrottleThreshold()

The threshold number of messages logged during the evaluation period which enables or disables the throttling.

getLogMonitoringThrottleMessageLength

int getLogMonitoringThrottleMessageLength()

Cut-off length of the log message for evaluation during throttle period. The log message length is truncated to this length for evaluation of repeated logging events.
