Method Details

start

public void start()

Specified by:

start in interface LifeCycle

Overrides:

start in class SyslogAppenderBase<ILoggingEvent>

createOutputStream

public SyslogOutputStream createOutputStream()
                                      throws SocketException,
UnknownHostException

Specified by:

createOutputStream in class SyslogAppenderBase<ILoggingEvent>

Throws:

SocketException

UnknownHostException

getSeverityForEvent

public int getSeverityForEvent(Object eventObject)

Convert a level to equivalent syslog severity. Only levels for printing methods i.e DEBUG, WARN, INFO and ERROR are converted.

Specified by:

getSeverityForEvent in class SyslogAppenderBase<ILoggingEvent>

See Also:

SyslogAppenderBase.getSeverityForEvent(java.lang.Object)

postProcess

protected void postProcess(Object eventObject,
 OutputStream sw)

Overrides:

postProcess in class SyslogAppenderBase<ILoggingEvent>

buildLayout

public Layout<ILoggingEvent> buildLayout()

Specified by:

buildLayout in class SyslogAppenderBase<ILoggingEvent>

isThrowableExcluded

public boolean isThrowableExcluded()

setThrowableExcluded

public void setThrowableExcluded(boolean throwableExcluded)

Setting throwableExcluded to true causes no Throwable's stack trace data to be sent to the syslog daemon. By default, stack trace data is sent to syslog daemon.

Parameters:

throwableExcluded -

Since:

1.0.4

getStackTracePattern

public String getStackTracePattern()

See {@link #setStackTracePattern(String).

Returns:

the stackTraceSuffixPattern

Since:

1.0.4

setStackTracePattern

public void setStackTracePattern(String stackTracePattern)

Stack trace lines are sent to the syslog server separately from the main message For stack trace lines, the stackTracePattern is used instead of SyslogAppenderBase.suffixPattern. The stackTracePattern option allows specification of a separately format for the non-standardized part of stack trace lines.

Parameters:

stackTracePattern -

Since:

1.0.4
