How to configure a NATS appender in LOGBack

LOGBack assumes that you have a logback.xml configuration in your classpath.

See below a minimal logback.xml configuration that would send all the logging events to the output console and to a NATS topic called 'jenkins' to a local broker running on the localhost at port 4222.

    <appender name="NATS" class="com.gerritforge.logback.nats.NatsTopicAppender">
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
      <!-- encoders are assigned the type
           ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
        <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>

    <root level="INFO">
        <appender-ref ref="STDOUT"/>
        <appender-ref ref="NATS"/>
