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 Go1.9 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
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.

guide on the Prometheus
