Migrating Jaeger tracing from OpenTracing to OpenTelemetry; Add OTLP exporter #5411

metonymic-smokey · 2022-06-09T11:40:30Z

part of fixing #1972

I added CHANGELOG entry for this change.
Change is not relevant to the end user.

Changes

This PR provides two changes that brings us closer to closing the gap between migrating from OpenTracing to OpenTelemetry, in particular:
a) This moves Jaeger client from OpenTracing to OpenTelemetry, without breaking changes. This means users can keep using their existing tracing configuration (some options will now not have any effect, but these are the ones that are obsolete after move to OTEL; read more in the updated documentation in the PR)
b) This adds the OTLP exporter, meaning now users will be able to leverage this protocol as well, with support of both gRPC and HTTP client.

Verification

Added E2E tests to validate Jaeger tracing
Manual tests

@matej-g could you please review my current progress, when you're free.

I've created a function which returns an OTLP exporter but I'm not sure how to use the exporter.
Working on E2E testing and pushed a draft commit for it, but I'll probably take some time for it.

TODO:

E2E:
todo - Fix E2E draft.
Jaeger:
Add more options from config.
Unit tests(similar to google_cloud.go)
OTLP Package:
Test locally.
Update docs with example config for OTLP package.

Thanks!

 )

 type TracingConfig struct {
 	Type   TracingProvider `yaml:"type"`
 	Config interface{}     `yaml:"config"`
 }

+// NewOTELTracer returns an OTLP exporter based tracer.
+func NewOTELTracer(ctx context.Context, logger log.Logger) trace.Tracer {


So my thought was to simply add a new TracingProvider const to the list we have above, simply named OTLP. It would be yet another package under tracing directory, just as we have jaeger, google_cloud etc.

Then, an OTLP exporter should be simply one of the switch cases in the factory function below. We should also probably take some config from YAML, same we do for other tracing provider.

I have created a new package otlp in a recent commit with some options for configuration. I will try to add some more config options if possible.
Please let me know what you think.

Thank you @metonymic-smokey! I think this is going in the right direction, I provided some feedback which will hopefully unblock you (if not feel free to ask for more details).

As for checking traces in E2E test, we could simply do a HTTP request to Jaeger and parse the reply for the trace data we expect. You can take a look at an example from our other project here: https://github.com/observatorium/api/blob/main/test/e2e/traces_test.go#L195

@GiedriusS @matej-g i've updated the E2E tests and looks like they all pass :)
Thank you so much for working with me on this one!
