Modified: 17-Jun-2025   


Applies To

  • ThingWorx Platform 10.0 F000
  • logback.xml

Description

  • Starting from logback 1.3/Thingworx 10, there are alterations in the syntax of logback.xml
  • The incorporation of an <if> element within <appender>, <logger>, or <root> elements is prohibited and may produce unpredictable outcomes:
    • Before 1.3: 
      <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <if condition='property("JSON_LOGS_ENABLE").contains("true")'>
            <then>
                <encoder class="net.logstash.logback.encoder.LogstashEncoder">
                    <customFields>{"platformId": "${PLATFORM_ID}" }</customFields>
                </encoder>
            </then>
            <else>
                <encoder>
                    <pattern>${CONSOLE_LAYOUT_PATTERN}</pattern>
                </encoder>
            </else>
        </if>
    </appender>
    • After 1.3: 
      <if condition='property("JSON_LOGS_ENABLE").contains("true")'>
        <then>
            <appender class="ch.qos.logback.core.ConsoleAppender" name="CONSOLE">
                <encoder class="net.logstash.logback.encoder.LogstashEncoder">
                    <customFields>{"platformId": "${PLATFORM_ID}" }</customFields>
                </encoder>
            </appender>
        </then>
        <else>
            <appender class="ch.qos.logback.core.ConsoleAppender" name="CONSOLE">
                <encoder>
                    <pattern>${CONSOLE_LAYOUT_PATTERN}</pattern>
                </encoder>
            </appender>
        </else>
    </if>
