Enable Proxy Debug Logs for OpenTelemetry Data

Follow the steps below to enable debug logs for the OpenTelemetry trace data sent to the Wavefront proxy:

1. Open the <wavefront_config_path>/log4j2.xml file.

2. Add the configurations to enable and manage logs under <Appenders>.
   Example:

    <Appenders>
       <RollingFile name="OTLPDataFile" fileName="${log-path}/wavefront-otlp-data.log" filePattern="${log-path}/wavefront-otlp-data-%d{yyyy-MM-dd}-%i.log">
         	<PatternLayout>
             <pattern>%m%n</pattern>
         	</PatternLayout>
         	<Policies>
             <TimeBasedTriggeringPolicy interval="1" />
             <SizeBasedTriggeringPolicy size="100 MB" />
         	</Policies>
         	<DefaultRolloverStrategy max="10">
             <Delete basePath="${log-path}" maxDepth="1">
                <IfFileName glob="wavefront-otlp-data-*.log" />
               	<IfLastModified age="7d" />
             </Delete>
         	</DefaultRolloverStrategy>
       </RollingFile>
    </Appenders>
   

   Note: See the log4j2 documentation for information on each parameter.

3. Add the logger name for OTLPDataLogger inside <Loggers>.
   Example:

      <!-- Set level="ALL" to log OpenTelemetry/OTLP data to a file. -->
      <Loggers>
         <AsyncLogger name="OTLPDataLogger" level="ALL" additivity="false">
            <AppenderRef ref="OTLPDataFile" />
         </AsyncLogger>
      </Loggers>
   

4. Save the file.

Once the proxy debug logs are saved, you can see them in the directory you specified for log-path on your log4j2.xml file.
