Json-api logging with actual json message

I am troubleshooting a specific customer issue and like to monitor and log the actual json-api messages at the server

Currently the format of the json-api output is defined by the json-api-logback.xml

    <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>

    <logger name="io.netty" level="WARN" />
    <logger name="io.grpc.netty" level="WARN" />
    <logger name="ch.qos.logback" level="WARN" />

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

Can this be configured to contain the actual json-api message ?

I am using DAML JDK 1.13.1

Maybe the

–log-encoder json

argument is solution ? or is this just a conversion of the text logfiles in a json format ?

In which version of the json-api is this supported ? It appears not available in DAML SDK 1.13.1

As you suspect, --log-encoder json just changes the format of the log output itself.

Some contents of requests are encoded at --log-level DEBUG; however, nothing logs the contents of every request or response. For that, I would suggest looking to the options of whatever reverse proxy you have set up in front of JSON API.
