Auto-instrumentation injection for webservers (nginx, apache)

[svrnm]

For both nginx and apache there are modules that add otel to the webservers (otel-webserver-module).

Using them, it should be possible to inject otel into containers running one of them like it is done right now for different languages:

• Provide a docker image that downloads & installs the modules
• Provide the code for injection (like javaagent.go)

My first question is, if the project would accept such an addition to the auto-instrumentation injection?

Thanks!

I don't have objections, however I don't know how the instrumentation installation of the webserver/nginx works. If you could outline an approach that the operator could use it would be helpful.

Provide a docker image that downloads & installs the modules

The operator should ideally use pre-build images to avoid unnecessary long init times.

Sure, Will follow up with some details!

Makes sense!

thanks @svrnm, it is great. We will need the commitment to maintain the apache auto-instrumenation in the operator.

The operator supports a wide range of auto-instrumentations, and it is becoming increasingly hard to maintain all these integrations and fix user issues.

I understand that, similar situation as with many other pieces of the otel projects.

I think that adding auto-instrumentation through the operator is a key feature end users are looking for, so let me see what we can do to help with the maintenance of them (not only apache)
