Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

OpenTelemetry in 2023
Prometheus text exposition format is de-facto standard used in monitoring. It would be great building an official observability standard on top it. This format is much easier to debug and understand than OpenTelemetry for metrics. It is also more efficient, e.g. it requires less network bandwidth and less CPU for transfer than Otel for metrics.

Kubernetes prometheus metrics for running pods and nodes?
I've set up prometheus to monitor kubernetes metrics by following the prometheus documentation.

What is promeetheus monitoring?
Exporters are third-party tools that send metrics to the Prometheus server. When Prometheus cannot access metrics, it uses exporters. These exporters export metrics from systems and send the metrics to the Prometheus server. There are official and non-official exporters in Prometheus' GitHub organization.

OpenTelemetry Journey #00 - Introduction to OpenTelemetry
Maybe, you are asking yourself: "But I already had instrumented my applications with vendor-specific libraries and I'm using their agents and monitoring tools, why should I change to OpenTelemetry?". The answer is: maybe you're right and I don't want to encourage you to update the way how you are doing observability in your applications, that's a hard and complex task. But, if you are starting from scratch or you are not happy with your current observability infrastructure, OpenTelemetry is the best choice, independently of the backend telemetry tool that you are using. I would like to invite you to take a look at the number of exporters available in the collector contrib section, if your backend tracing tool is not there, probably it's already using the Open Telemetry Protocol (OTLP) and you will be able to use the core collector. Otherwise, you should consider changing your backend telemetry tool or contributing to the project creating a new exporter.

Did OpenTelemetry deliver on its promise in 2023?
Here's the example payloads for OTLP over JSON and example of how to ingest them: https://github.com/open-telemetry/opentelemetry-proto/tree/m...

Amazon EKS Monitoring with OpenTelemetry [Step By Step Guide]
An OTLP receiver can receive data via gRPC or HTTP using the OTLP format. There are advanced configurations that you can enable via the YAML file.

Transition to OpenTelemetry, enhanced policy testing, and more - Cerbos v0.32
Cerbos fully transitioned from OpenCensus to OpenTelemetry, a move that significantly boosts our metrics and tracing capabilities. This shift allows for more efficient integration with a variety of observability products supporting the OpenTelemetry protocol (OTLP) but also offers the flexibility to use push metrics and fine-tune trace sampling. With this update, configuration through the tracing block in Cerbos files is deprecated in favor of using OpenTelemetry environment variables.

OpenTelemetry is not just for Monitoring and Troubleshooting any longer. Announcing Tracetest Open Beta!
Networking is Easy (Really!) Since you install the agent directly into the environment where you are running your application, there is no complex networking. When developing in localMode, the agent listens on the common OpenTelemetry Line Protocol (OTLP) on ports 4317 & 4318 automatically.

OpenTelemetry in 2023
Oh nice, thank you (and also solumos) for the links! It looks like oteps/pull/171 (merged June 2023) expanded and superseded the opentelemetry-proto/pull/346 PR (closed Jul 2022) [0]. The former resulted in merging OpenTelemetry Enhancement Proposal 156 [1], with some interesting results especially for 'Phase 2' where they implemented columnar storage end-to-end (see the Validation section [2]):
* For univariate time series, OTel Arrow is 2 to 2.5 better in terms of bandwidth reduction ... and the end-to-end speed is 3.1 to 11.2 times faster
* For multivariate time series, OTel Arrow is 3 to 7 times better in terms of bandwidth reduction ... Phase 2 has [not yet] been .. estimated but similar results are expected.
* For logs, OTel Arrow is 1.6 to 2 times better in terms of bandwidth reduction ... and the end-to-end speed is 2.3 to 4.86 times faster
* For traces, OTel Arrow is 1.7 to 2.8 times better in terms of bandwidth reduction ... and the end-to-end speed is 3.37 to 6.16 times faster
