About opentelemetry-go
OpenTelemetry Go is the Go implementation of OpenTelemetry, the vendor neutral observability framework. It provides a set of APIs that let Go programs directly measure the performance and behavior of their own software, then send the resulting telemetry to observability platforms. The project lives in the Go ecosystem and is distributed as the module go.opentelemetry.io/otel , published on pkg.go.dev and licensed under Apache 2.0. It is a long running, actively maintained repository, roughly seven years old, with a large contributor base and a steady release cadence.
