Michal 5ae07d4c2f include build info in Prometheus metrics (#22819) ... Related to: https://github.com/go-gitea/gitea/issues/18061 This PR adds build info to the Prometheus metrics. This includes: - goarch: https://pkg.go.dev/runtime#GOARCH - goos: https://pkg.go.dev/runtime#pkg-constants - goversion: https://pkg.go.dev/runtime#Version - gitea version: just exposes the existing code.gitea.io/gitea/modules/setting.AppVer It's a similar approach to what some other Golang projects are doing, e.g. Prometheus: https://github.com/prometheus/common/blob/main/version/info.go example /metrics response from Prometheus: ``` # HELP prometheus_build_info A metric with a constant '1' value labeled by version, revision, branch, goversion from which prometheus was built, and the goos and goarch for the build. # TYPE prometheus_build_info gauge prometheus_build_info{branch="HEAD",goarch="amd64",goos="linux",goversion="go1.19.4",revision="c0d8a56c69014279464c0e15d8bfb0e153af0dab",version="2.41.0"} 1 ``` /metrics response from gitea with this PR: ``` # HELP gitea_build_info Build information # TYPE gitea_build_info gauge gitea_build_info{goarch="amd64",goos="linux",goversion="go1.20",version="2c6cc0b8c"} 1 ``` Signed-off-by: Michal Wasilewski <mwasilewski@gmx.com> <!-- Please check the following: 1.
