sync.Pool is after all faster than the home-made free list. Especially under contention. To prove that, this commit also adds a benchmark for concurrent fingerprint calculation.

Overview
This is the Prometheus Go client library. It provides several distinct functions, and there is separate documentation for each respective component. You will want to select the appropriate topic below to continue your journey:
-
See the exposition library if you want to export metrics to a Prometheus server or pushgateway
-
See the consumption library if you want to process metrics exported by a Prometheus client. (The Prometheus server is using that library.)
Getting Started
- The source code is periodically indexed: Go Exposition Client.
- All of the core developers are accessible via the Prometheus Developers Mailinglist.
Testing
$ go test ./...
