Why Different Instrumentation is there for log4j2.17 and log4j2.7?

[saytoshivam]

As i want to add "span name" together with traceId ,spanId etc in logs by overiding log4j instrumentation.So do i need to do it separately for different versions of log4j?The below code snippets is working fine for me , but i have doubt if they will work for all log4j versions.

hi @saytoshivam, I'd probably recommend creating your own Log4j2 ContextDataProvider to implement this, instead of trying to override the javaagent instrumentation
