Description

I want to use NginxAutoInstrumentation, but found it couldn't work with the default configuration. Even i use the official assert in instrumentation-nginx

Steps to Reproduce

0. install latest opentelemetry-operator follow on README
1. apply instrumentation: kubectl apply -f 00-install-instrumentation.yam
2. add instrumentation annotations to 01-install-app.yaml:
   
3. apply 01-install-app.yaml: kubectl apply -f 01-install-app.yaml
4. access the uri http://localhost:8765

Expected Result

should not print error log

Actual Result

error when initAgent, and couldn't generate spans

Additional context

the default log4cxx xml file should be opentelemetry_sdk_log4cxx.xml instead of appdynamics_sdk_log4cxx.xml
