Get solution for this, just add the Converter in logback.xml: ``` <configuration> <conversionRule conversionWord="tid" converterClass="org.apache.skywalking.apm.toolkit.log.logback.v1.x.LogbackPatternConverter"/> <!--appender--> <appender name="logstash" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${LOG_PATH:-.}/${APP_NAME}/${APP_NAME}_json.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${LOG_PATH:-.}/${APP_NAME}/${APP_NAME}_json.log.%d{yyyy-MM-dd}.gz</fileNamePattern> <maxHistory>30</maxHistory> </rollingPolicy> <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder"> <providers> <timestamp> <timeZone>UTC</timeZone> </timestamp> <pattern> <pattern> { "level": "%level", "ip": "${IP}", "service": "${APP_NAME:-}", "tid": "%tid", "pid": "${PID:-}", "thread": "%thread", "class": "%logger{1.}:%L", "message": "%message", "stackTrace": "%exception{10}" } </pattern> </pattern> </providers> </encoder> </appender> </configuration> ``` Thans anyway.
