$ git clone git@github.com:Virtual-Instruments/cloudwatch-log4j-appender.git
$ cd CloudWatchAppender
$ mvn install

    <CloudWatchAppender name="CloudWatchAppender"
                           awsLogGroupName="MyGroup"
                           awsLogStreamName="CloudWatchAppender"
                           awsLogStreamFlushPeriodInSeconds="5">
      <PatternLayout>
        <Pattern>%5p | %d{ISO8601}{UTC} | %t | %C | %M:%L | %m %ex %n</Pattern>
      </PatternLayout>
    </CloudWatchAppender>

Optional log4j appender plugin attributes:

• awsLogGroupName: the name of the AWS log group (default: "unknown").
• awsLogStreamName: the name of the AWS log stream inside the AWS log group from above (default: "Test Stream"). Might also be be overridden by the LOG_STREAM_NAME environment variable (see below). Note that the stream name will always be suffixed by the current timestamp. This means that every time the logger restarts, it will create a new log stream.
• awsLogStreamFlushPeriodInSeconds: the period of the flusher (default: 5).

Your AWS credentials should be specified in the AWS environment in the standard way. For testing purposes, you can override the credentials in the environment:

• AWS_ACCESS_KEY: sets the AWS Access Key.
• AWS_SECRET_KEY: sets the AWS Secret Key.

You can also supply the AWS log stream name via environment:

• LOG_STREAM_NAME: sets the AWS log stream name.
