client_golang VS go-formatter

Prometheus, an open-source systems monitoring and alerting toolkit, has client libraries that allow you to instrument your services in a variety of languages. Here's an example of how you might use the Go client library to expose metrics on an HTTP endpoint. We will leverage the prometheus go client to expose metrics and create them.

I'd recommend github.com/victoriametrics/metrics for exporting custom metrics in Prometheus format. It is easier to use than the github.com/prometheus/client_golang.

Start at the official documentation and the Go client library .

DataDog can read Prometheus metrics. Note that this approach works for metrics but not for traces although you can configure DataDog to receive OpenTelemetry traces as well https://github.com/prometheus/client_golang

For Go, the standard is to use Prometheus and the Prometheus Go client library.

AFAIK, no. There are some helper frameworks [1], but none of them is dominant. Two possible reasons: it's quite easy to write a (web) service with the library functions (it even includes a gzip stream), and it's practically impossible to write an ORM framework like you have in Java and Python, so the Go frameworks I've seen are basically a bunch of helper functions.
