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.
This library requires Go1.9 or later.
Important note about releases and stability
This repository generally follows Semantic
Versioning. However, the API client in
elasticsearch/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.
Instrumenting applications
The
elasticsearch
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/elasticsearch
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.
