Hello,

  I am trying to fetch the trace id generated by open telemetry with only configuration in log4j2.xml file and web.xml file.

  I created a stack overflow ticket, see : [https://stackoverflow.com/questions/70194344/how-to-access-request-header-value-with-log4j2]

 

  Is it possible with the log4j2 lookup to be compatible with open telemetry?

  I tried to use ${web:header.traceId} and it just does not work. I have followed the config. So, am I missing something to make it work?

  I saw that even without the web.xml config I added, the ${web:rootDir} still works.

  There is almost no information on the internet on how to make it work with Open Telemetry so I am asking to the expert here. Open Telemetry is basically a field/value that is set in the HTTP request header.

 

Thank you
