This seem what OTel is converging towards, see https://github.com/open-telemetry/oteps/pull/149 . I see pros and cons with base-10 vs base-2. They are discussed in detail in that OTel PR, and the gist of the discussion is pretty much in line with my design doc. Since the balance is easy to tip here, I think we should go with base-2 if OTel picks base-2. This also seems to be in agreement with several proprietary solution (see again the discussion on that OTel PR.) The idea to make the number of buckets per power of 2 (or formerly 10) a power of 2 itself was also sketched out in the design doc already. It guarantees mergeability of different resolutions. I was undecided between making it a recommendation or mandatory. Now I think it should be mandatory as it has the additional benefit of playing well with OTel's plans. This commit also addresses a number of outstanding TODOs. Signed-off-by: beorn7 <beorn@grafana.com> |

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 Go1.13 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.
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.
