Support NGINX 1.26.1 (stable) and 1.27.0 (Main)

[wcawthron]

Describe your environment
At present, my NGINX versions have required patching for major vulnerabilities found in 1.26.0 and 1.25.5. With these having been patched, the OTEL module is no longer compatible resulting in a loss of telemetry data for these installations.

Steps to reproduce
Download current webserver release of v1.1.0

What is the expected behavior?
Module available for patched and at present secure versions of nginx.

What is the actual behavior?
Module only available for versions with know high vulnerabilities.

Additional context
Current vulnerabilities for 1.26.0 and 1.25.5 are available here: https://nginx.org/en/security_advisories.html
Upgrading to 1.26.1 and 1.27.0 is the current requirement to maintain a secure environment.

Is the issue for the OTel WebServer module or nginx instrumentation?

[FiskilBen]

For me the issue was with the nginx instrumentation. I followed the steps here - https://opentelemetry.io/blog/2022/instrument-nginx/ but the nginx server failed to start due to incompatible versions between the opentelemetry module and the nginx server.

Rechanging the label to WebServer in this case.

There's another nginx instrumentation available: https://github.com/open-telemetry/opentelemetry-cpp-contrib/tree/main/instrumentation/nginx

I'll make a release soon, but meanwhile the prebuilt binaries can be downloaded from the last CI run:
