chore/otel-collector: upgrade to v0.103.0, remove jaegerexporter#63171

bobheadxi · 2024-06-07T22:14:14Z

Thread: https://sourcegraph.slack.com/archives/C1JH2BEHZ/p1717797870638299

One problem caused by this upgrade is that the deprecated jaegerexporter no longer builds at all with the last published version, so for the upgrade to go through it must be removed. I've updated local sg start to work with this change, but some Release team support is needed for deployment configuration + customer-facing docs changes: https://sourcegraph.slack.com/archives/C1JH2BEHZ/p1718143249191349?thread_ts=1717797870.638299&cid=C1JH2BEHZ, since current guidance asks customers to configure jaegerexporter.

Part of https://linear.app/sourcegraph/issue/SEC-1680

Closes https://linear.app/sourcegraph/issue/CORE-177

Test plan

Followed steps shared in https://sourcegraph.slack.com/archives/C04MYFW01NV/p1718136211292469 to run locally, since sg run jaeger otel-collector alone is insufficient to get updated images:

diff --git a/wolfi-images/opentelemetry-collector.yaml b/wolfi-images/opentelemetry-collector.yaml
index b995a3d531b..76de80d4f84 100644

plus sg wolfi lock opentelemetry-collector will make sg run otel-collector use the correct image.

The above diffs SHOULD NOT be committed. The lock should happen post-merge.

Spot-checked some traces locally with:

sg run jaeger otel-collector
sg start

Changelog

OpenTelemetry Collector: Upgraded OpenTelemetry Collector to v0.103.0
OpenTelemetry Collector: The deprecated jaegerexporter has been removed. Users of exporter: { jaeger: ... } in the OpenTelemetry Collector should use exporter: { otlp/jaeger: ... } to send traces directly to Jaeger via its OTLP receiver.
- Users of the default Jaeger configurations now need to provide JAEGER_OTLP_GRPC_PORT as well as the existing JAEGER_HOST configuration.

This PR updates GRPC from 1.61 to 1.64 which deprecates the .Dial* functions. This is caught by the CI, and we most likely want to update it.

Looking at jaegertracing/jaeger#5330 it seems that there are a few little semantics differences to take in account, making this potentially not trivial.

I'll ping the source team as @ggilmore has been leading this for a while.

eseliger · 2024-06-10T08:27:48Z

I think I am fine with keeping the deprecated method for now, given the complexity laid out in the thread JH linked.
I ran the stack locally and traces seem to be properly attached to parent spans across services, and gRPC doesn't seem to fail.

The release notes say:

These will continue to be supported throughout 1.x,

So LGTM.

doc/dependency_decisions.yml

+  - MPL-2.0
+  - :who: 
+    :why: 
+    :versions: []


this seems to be true for all things in here, and is unrelated to the PR, but I am confused why versions is empty :D

I think it's optional fields you can record when tracking a dependency change, e.g. "this code was MPL for vX to vY"

Sad that these all had to upgrade for this otel bump, makes it harder to track down regressions :)

yeah the dependency tree is pretty wild. I did upgrade aggressively but we've ran into more issues with not upgrading in lockstep, than we have with upgrading everything OTEL depends on in one go

Do we know where this is coming from? cc @varungandhi-src perhaps?

@jhchabran sorry, I don't know about this. I've flagged this in the search platform team channel.

Apparently we use go.opentelemetry.io/otel to encode values in the s-exp printer for the tests (see here).

Without looking at the source of go.opentelemetry.io/otel, My best bet is they changed the way they process arrays.

This looks related

Thanks @stefanhengl. Do you think this is creating a problem here? (I don't have context on this, was flagged as a reviewer and spotted this, which prompted me to reach out as this could break something)

I don't think so. As far as I can see it is only used in tests.

We need to update the wolfi lock image for https://github.com/sourcegraph/sourcegraph/pull/63171 in order for `sg run` to work We've made all the changes to the deployment repos for this to be pushed out in the release today. ## Test plan  Manually tested ## Changelog  - fix(build): update wolfi lock for otel-collector

…#63790) The OTEL upgrade https://github.com/sourcegraph/sourcegraph/pull/63171 bumps the `prometheus/common` package too far via transitive deps, causing us to generate configuration for alertmanager that altertmanager doesn't accept, at least until the alertmanager project cuts a new release with a newer version of `promethues/common`. For now we forcibly downgrade with a replace. Everything still builds, so we should be good to go. ## Test plan `sg start` and `sg run prometheus`. On `main`, editing `observability.alerts` will cause Alertmanager to refuse to accept the generated configuration. With this patch, all is well it seems - config changes go through as expected. This is a similar test plan for https://github.com/sourcegraph/sourcegraph/pull/63329 ## Changelog - Fix Prometheus Alertmanager configuration failing to apply `observability.alerts` from site config
