This is the Go client library for Prometheus. It has two separate parts, one for instrumenting application code, and one for creating clients that talk to the Prometheus HTTP API.
This library requires Go1.17 or later.
Important note about releases and stability
This repository generally follows Semantic Versioning. However, the API client in prometheus/client_golang/api/… is still considered experimental. Breaking changes of the API client will not trigger a new major release. The same is true for selected other new features explicitly marked as EXPERIMENTAL in CHANGELOG.md.
Features that require breaking changes in the stable parts of the repository are being batched up and tracked in the v2 milestone. The v2 development happens in a separate branch for the time being. v2 releases off that branch will happen once sufficient stability is reached. In view of the widespread use of this repository, v1 and v2 will coexist for a while to enable a convenient transition.
