Prometheus Go client library
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.
Version Compatibility
This library supports the three most recent major releases of Go. While it may function with older versions, we only provide fixes and support for the currently supported Go releases.
[!NOTE] See our Release Process for details on compatibility and support policies.
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, but plans for further development of v2 at the moment.
NOTE: The initial v2 attempt is in a separate branch. We also started experimenting on a new
prometheus.V2.*APIs in the 1.x's V2 struct. Help wanted!
Instrumenting applications
The
prometheus directory
contains the instrumentation library. See the
guide on the Prometheus
website to learn more about instrumenting applications.
The
examples directory
contains simple examples of instrumented code.
Client for the Prometheus HTTP API
The
api/prometheus directory
contains the client for the
Prometheus HTTP API. It allows you
to write Go applications that query time series data from a Prometheus
server. It is still in alpha stage.
Where is model, extraction, and text?
The model packages has been moved to
prometheus/common/model.
The extraction and text packages are now contained in
prometheus/common/expfmt.
Contributing and community
See the contributing guidelines and the Community section of the homepage.
client_golang community is also present on the CNCF Slack #prometheus-client_golang.
