Field Detail

PATTERN

static final String PATTERN
ObjectName pattern ("org.apache.logging.log4j2:type=%s,component=AsyncAppenders,name=%s" ) for AsyncAppenderAdmin MBeans. This pattern contains two variables, where the first is the name of the context, the second is the name of the instrumented appender.

You can find all registered AsyncAppenderAdmin MBeans like this:

 MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
 String pattern = String.format(AsyncAppenderAdminMBean.PATTERN, "*", "*");
 Set<ObjectName> appenderNames = mbs.queryNames(new ObjectName(pattern), null);
 

Some characters are not allowed in ObjectNames. The logger context name and appender name may be quoted. When AsyncAppenderAdmin MBeans are registered, their ObjectNames are created using this pattern as follows:

 String ctxName = Server.escape(loggerContext.getName());
 String appenderName = Server.escape(appender.getName());
 String name = String.format(PATTERN, ctxName, appenderName);
 ObjectName objectName = new ObjectName(name);

Method Detail

getName

String getName()
Returns the name of the instrumented AsyncAppender.

Returns:
the name of the AsyncAppender

getLayout

String getLayout()
Returns the result of calling toString on the Layout object of the instrumented AsyncAppender.

Returns:
the Layout of the instrumented AsyncAppender as a string

isIgnoreExceptions

boolean isIgnoreExceptions()
Returns how exceptions thrown on the instrumented AsyncAppender are handled.

Returns:
true if any exceptions thrown by the AsyncAppender will be logged or false if such exceptions are re-thrown.

getErrorHandler

String getErrorHandler()
Returns the result of calling toString on the error handler of this appender, or "null" if no error handler was set.

Returns:
a string description of all configured filters for this appender

getAppenderRefs

String[] getAppenderRefs()
Returns a String array with the appender refs configured for the instrumented AsyncAppender.

Returns:
the appender refs for the instrumented AsyncAppender.

isIncludeLocation

boolean isIncludeLocation()
Returns true if this AsyncAppender will take a snapshot of the stack with every log event to determine the class and method where the logging call was made.

Returns:
true if location is included with every event, false otherwise

isBlocking

boolean isBlocking()
Returns true if this AsyncAppender will block when the queue is full, or false if events are dropped when the queue is full.

Returns:
whether this AsyncAppender will block or drop events when the queue is full.

getErrorRef

String getErrorRef()
