Top 23 Go Opentelemetry Projects

In this episode, we’ll integrate OpenTelemetry with our ASP.NET minimal API and trace everything from database calls to cache hits — all visualized in Jaeger. We’ll also learn how to spot inefficiencies, validate cache behavior, and instrument our code for insights.

The puzzle is getting complete with the addition of the OpenTelemetry collector. It is the layer that connects the generic OpenTelemetry exporter to the specific backend, which in our case is Elasticsearch.

Project mention: OpenFeature – a vendor-agnostic, community-driven API for feature flagging | news.ycombinator.com | 2024-10-25
Speaking as an open-source feature flag 'vendor' (https://github.com/flipt-io/flipt), the OpenFeature organization has been a joy to work with. They are very welcoming of new contributors (e.g., implementing a provider SDK in a new language).
If you're interested in this space I'd recommend lurking in their CNCF Slack Channel https://cloud-native.slack.com/archives/C0344AANLA1

While the batch and memory processors are part of the core collector repository, the resource processor is part of the contrib collection. The resource processor is particularly useful for adding common metadata to all telemetry data passing through the collector. For example, we can use it to amend our logs with the service name and environment to enrich the information that is sent to the backend. You can read more about it here.

gigapipe
qryn is a polyglot, high-performance observability framework for ClickHouse. Ingest, store and analyze logs, metrics and telemetry traces from any agent supporting Loki, Prometheus, OTLP, Tempo, Elastic, InfluxDB and many more formats and query transparently using Grafana or any other compatible client.
I'm not the person you asked -- and I also want to be transparent that I only PoC-ed it and due to external circumstances didn't get it all the way out to production -- but I really like how https://github.com/metrico/qryn (AGPLv3) thinks about the world. It is, like SigNoz, unified (logs, metrics, traces) but it actually implements several of the common endpoint schemes allowing it to pretend to be "your favorite tool" which plausibly helps any integration story <https://github.com/metrico/qryn#%EF%B8%8F-query> and <https://github.com/metrico/qryn#-vendors-compatibility>
I was going to take advantage of Clickhouse using S3 as warm-to-cold storage since my mental model is that most logs, metrics, and traces are written and not read https://clickhouse.com/docs/en/integrations/s3#configuring-s...
I believe one could do that with SigNoz, too, so I don't mean to imply that trickery was qryn specific, just that I didn't want to get into the "constantly resizing io3 PVC" game

Adopting OpenTelemetry does not have to be hard for common use-cases. On Kubernetes, the Dash0 operator (https://artifacthub.io/packages/search?repo=dash0-operator) automatically instruments Node.js and Java workloads (and soon other runtimes; Disclaimer: I am one of its authors) with just a custom resource created in a namespace.
Automatic instrumentation on Kubernetes is also provided by the community OpenTelemetry (https://github.com/open-telemetry/opentelemetry-operator).
I am certainly biased here because OpenTelemetry and Prometheus have been at the core of my professional life for the past half decade, but I think that the biggest challenge, is that there are many different ways to get you to a good setup, and people get lost in the discovery of the available options.
