Class LogImplWebguiLogging

java.lang.Object
  kieker.common.logging.LogImplWebguiLogging

All Implemented Interfaces:

Log

public final class LogImplWebguiLogging
extends Object
implements Log

This is a simple logger for the Kieker WebGUI. It stores the log messages within a buffer of a static size. If the buffer is full, the oldest entry will be removed for new entries. As the entries have to be accessible from outside, the queues are stored statically.

Since:

1.6
