partial Config

load_module /opt/opentelemetry-webserver-sdk/WebServerModule/Nginx/1.22.0/ngx_http_opentelemetry_module.so;

http {
  # Nginx will handle gzip compression of responses from the app server

  gzip_types text/plain application/json;
  gzip_min_length 1000;
  include /etc/nginx/conf.d/opentelemetry_module.conf;

NginxModuleServiceName RBCS;
NginxModuleServiceNamespace DEV;
NginxModuleServiceInstanceId jaeger;
NginxModuleResolveBackends ON;
NginxModuleTraceAsError On;

Steps to reproduce

  1. Boot up RHEL 7 AMI
  2. Install nginx from the nginx stable repo
  3. Download/install the latest otel-webserver-module release
  4. create /etc/ld.so.conf.d/nginx.conf and add /opt/opentelemetry-webserver-sdk/sdk_lib/lib to the file
  5. Create /etc/nginx/conf.d/opentelemetry_module.conf
  6. Start NGINX

What is the expected behavior? I would expect to see traces, we use the same config, on debian docker images and have no problems.

What is the actual behavior?

We are experiencing similar issue on RHEL 7.3:

# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.3 (Maipo)

# nginx -v
nginx version: nginx/1.23.1

We have similar issues, for Apache: 

cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)

Could you please try the latest main branch? https://github.com/open-telemetry/opentelemetry-cpp/pull/2464 fixes a crash problem with gcc 4.8.

royteeuwen commented 5 months ago

The latest main branch works for me! But I do have a PR open to fix some other things to make it work for our setup. Would you be able to look at this @owent ? see https://github.com/open-telemetry/opentelemetry-cpp-contrib/issues/364

Sorry but I'm not fimalar with nginx API, maybe @seemk @tobiasstadler @kpratyus @ajaynagariya @debajitdas could help.
