Avalon Logging

Logkit Configuration Example

The following is an example of a LogKit configuration. The example establishes three target, a file target, a console stream target, and a multicast target. Logging events are assigned to the multicast target resulting in event delivery to both the file and console. The formats of the respective targets are selected for the relative roles. The file target handles full reporting with stack trace information. The console target handles a more consolidated error reporting scheme.

  <targets>

    <!--
    This target establishes output to the the System.out stream.
    The format argument ensures that we don't get stack traces -
    but just the error report.

       <name>System.out</name>
       <format type="console"/>

    named targets.
