Class CloudAppender

java.lang.Object
  org.apache.log4j.AppenderSkeleton
      com.rexsl.log.CloudAppender

All Implemented Interfaces:

Appender, OptionHandler

public final class CloudAppender
extends AppenderSkeleton

Log appender, for cloud loggers.

Configure it in your log4j.properties like this (just an example, which uses loggly.com HTTP log consuming interface):

 log4j.rootLogger=WARN, LOGGLY, CONSOLE
 log4j.appender.LOGGLY=com.rexsl.log.CloudAppender
 log4j.appender.LOGGLY.feeder=com.rexsl.log.HttpFeeder
 log4j.appender.LOGGLY.feeder.url=https://logs.loggly.com/inputs/0604e96...
 log4j.appender.LOGGLY.layout=org.apache.log4j.PatternLayout
 log4j.appender.LOGGLY.layout.ConversionPattern = [%5p] %t %c: %m\n
 log4j.appender.CONSOLE=com.netbout.log.CloudAppender
 log4j.appender.CONSOLE.feeder=com.rexsl.log.ConsoleFeeder
 log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
 log4j.appender.CONSOLE.layout.ConversionPattern = [%5p] %t %c: %m\n
 

You can extend it with your own feeding mechanisms. Just implement the Feeder interface and add an instance of the class to the appender.

The class is thread-safe.
