Ingress-NGINX 1.10.0 has dropped support for OpenTracing and Zipkin, favoring OpenTelemetry instead.

The OpenTelemetry module used by Ingress-NGINX is based on a old commit, and has received updates since then.

The correct value is not set according "span->SetStatus(trace::StatusCode::kError);".

Per default it's not correct set with "span->SetStatus(trace::StatusCode::kOk);" if there a trace with error (>=http_code 500).

(in Datadog it's metric trace.nginx.server.errors.)

The changes according Ingress-NGINX 1.11.2 with my branch solved the problem according trace error status: https://github.com/tsimonitoring/ingress-nginx/tree/release-1.11.3-patch-opentelemetry-cpp-and-contrib-and-proto

As example tested on my side in Datadog.

There are correct OPENTELEMETRY_CPP_VERSION, OPENTELEMETRY_PROTO_VERSION, OPENTELEMETRY_CONTRIB_COMMIT in build.sh incl. apk upgrade abseil-cpp-crc-cpu-detect (add) in Dockerfile NGINX.

Before (https://i.imgur.com/LpvotMx.png) there was no shipped metric according error_status per OpenTelemetry Module.

After (https://i.imgur.com/xvz6b05.png) you can see the shipped error metric also in trace view or see diag example (https://i.imgur.com/xEEY2Ep.png).

Hi @matthias-haase. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Why is abseil-cpp-crc-cpu-detect needed?

[matthias-haase]

@strongjz abseil-cpp-crc-cpu-detect in Dockerfile needed by shared object.

otel_ngx_module.so -> libopentelemetry_exporter_otlp_grpc.so -> libabsl_crc_cpu_detect.so.2308.0.0

Error message clearify this - without libabsl_crc_cpu_detect.so.2308.0.0 you get the errormessage:

here are the repos, which work "together"
OPENTELEMETRY_CPP_VERSION -> https://github.com/open-telemetry/opentelemetry-cpp/releases
#+export OPENTELEMETRY_CPP_VERSION="v1.17.0"

OPENTELEMETRY_PROTO_VERSION -> https://github.com/open-telemetry/opentelemetry-proto/releases
#+export OPENTELEMETRY_PROTO_VERSION="v1.3.2"

OPENTELEMETRY_CONTRIB_VERSION -> https://github.com/open-telemetry/opentelemetry-cpp-contrib/releases
#+export OPENTELEMETRY_CONTRIB_COMMIT=f6d29426ee9b4d6b476c09ca3cb9bed3cf23906f
OPENTELEMETRY_CONTRIB_COMMIT is the newest commit - an no new version tag is established here. :(

Answer: OPENTELEMETRY_CONTRIB_COMMIT creates libopentelemetry_exporter_otlp_grpc.so, which needs abseil-cpp-crc-cpu-detect.
abseil-cpp-crc-cpu-detect installs the needed libabsl_crc_cpu_detect.so.2308.0.0

Proof:

src|opentelemetry-cpp-contrib.git $ find . -type f|xargs grep libopentelemetry_exporter_otlp_grpc
./opentelemetry-cpp-contrib.git/instrumentation/otel-webserver-module/build.gradle:    from("${modDepDir}/opentelemetry/${cppSDKVersion}/lib/libopentelemetry_exporter_otlp_grpc.so") { it.into "sdk_lib/lib" }
./opentelemetry-cpp-contrib.git/instrumentation/otel-webserver-module/opentelemetry_module.conf:LoadFile /opt/opentelemetry-webserver-sdk/sdk_lib/lib/libopentelemetry_exporter_otlp_grpc.so

The other repos do not have a entry like "libopentelemetry_exporter_otlp_grpc".

@strongjz in hope this helps push a faster commit, because:

With azure kubernetes version 1.31 there is a needed pressure using newsest nginx.

Problem: newest nginx uses opentelemetry instead opentracing, but trace status error is not shipping in a correct way.

Due to need use correct monitoring with tracing there's a stop according go to newer versions with nginx.

An this stopps using next kubernetes version 1.31, which makes the pressure from azure.

That's why i created the pull request: #12371

How can someone push and go to a faster with minimal time delay integrate such a change of 3 lines in build.sh and 1 in Dockerfile in images/nginx/rootfs/ ?
Can you help?
THX a lot all for help!

Can you please come up with a more descriptive PR title? This goes into the commit message on main branch and the changelog on release. Also we prefer tagged releases over just picking latest.

[Gacko]

Also we are currently in the process of releasing v1.12. This change won't make it in there and will earliest be included in v1.13. Additionally we are currently working on bumping the NGINX to OpenResty v1.27, so let's just postpone this here until we bumped NGINX itself and try to integrate it based on that.

Hello,
i'm a newbie.
This is my first PR. But not my last. I'm open source fan and will give further more PR's, if i can help.
can you help me and suggest a better title incl. info what i must do for change PR title - bot message or what ever, i do not know , what i can do :( ?
THX a lot !
I suggest another title like this: 'This fix resolves shipping correct value in traces according "span->SetStatus(trace::StatusCode::kError);".'
Ok or any hint ?

Is there a way also update release v1.10 and v1.11 and 1.12, because there are a lot of deployments using a "buggy" opentelemetry module with not correct shipped trace error status?
Can i create new PR's on every v1.10 and v1.11 and 1.12 like i did on main branch ?

Background:

This would helps test with current deploments in current kubernetes deployments and help go forward to new versions without risk in e2e-tests, incl. possibility if there's a "go back", you cab use the patch with older versions.

Hint:
With azure kubernetes version 1.31 there is a needed pressure using newest nginx.
Problem: newest nginx uses opentelemetry instead opentracing, but trace status error is not shipping in a correct way.

THX for hint according older and current versions. You are the best!

Please do not file separate PRs on different branches. Back-porting changes is up to the maintainers of this project.

Also I'd like to note that at least I'm feeling a little pushed by you. I understand this might be urgent to you (or your employer), but still we are all doing this in our free time and are responsible for maintaining changes brought to us by contributors. So I'd like to ask you for patience while we are reviewing your proposal thoroughly.

[Gacko]

One additional note, also to other maintainers: The compilation of the NGINX base image is still broken at the moment. I'd highly appreciate not merging any changes to it as long as it hasn't been fixed. This just makes it more complicated.
