logback-json-logger

Build Status Download

This is a JSON encoder for Logback applications logger. It uses Mapped Diagnostic Contexts (MDC) to include appropriate context information in each log message too.

These are the properties (for your application.conf) that you can use to alter the log output:

appName = MyApplication
logger.json.dateformat = yyyy-MM-dd HH:mm:ss.SSSZZ

If you do not set the date format, it defaults to yyyy-MM-dd HH:mm:ss.SSSZZ.

You can then use the encoder in your logger configuration.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="uk.gov.hmrc.play.logging.JsonEncoder"/>
    </appender>

    <logger name="uk.gov" level="DEBUG"/>

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