Hi, A new minor version of prometheus/client_golang <https://github.com/prometheus/client_golang>, the instrumentation and the HTTP API client library for Prometheus in Go has been released! Please check it out and send feedback to GitHub Issues/Discussions.
The notable change is the ability to use extended standard Go runtime/metrics <https://pkg.go.dev/runtime/metrics> with `collectors.GoCollector`, see Example <https://github.com/prometheus/client_golang/blob/v1.13.0/prometheus/collectors/go_collector_latest_test.go#L263> here. You can enable one or all of them via simple regex. By default, only old MemStat metrics will be available (which can be disabled). We won't remove that in v1. Thanks to everyone who contributed to this release - we had 16 new contributors (!) helping this time with 23 total. - [CHANGE] Minimum required Go version is now 1.17 (we also test client_golang against the new 1.19 version). - [ENHANCEMENT] Added prometheus.TransactionalGatherer interface for promhttp.Handler use which allows using low allocation update techniques for custom collectors. #989 <https://github.com/prometheus/client_golang/pull/989> - [ENHANCEMENT] Added exemplar support to prometheus.NewConstHistogram. See ExampleNewConstHistogram_WithExemplar <https://github.com/prometheus/client_golang/blob/v1.13.0/prometheus/examples_test.go#L602> example on how to use it. #986 <https://github.com/prometheus/client_golang/pull/986> - [ENHANCEMENT] prometheus/push.Pusher now has context-aware methods that pass context to HTTP requests. #1028 <https://github.com/prometheus/client_golang/pull/1028> - [ENHANCEMENT] prometheus/push.Pusher has now Error method that retrieve last error. #1075 <https://github.com/prometheus/client_golang/pull/1075> - [ENHANCEMENT] testutil.GatherAndCompare provides now readable diff on failed comparisons. #998 <https://github.com/prometheus/client_golang/pull/998> - [ENHANCEMENT] Query API now supports timeouts. #1014 <https://github.com/prometheus/client_golang/pull/1014> - [ENHANCEMENT] New MetricVec method DeletePartialMatch(labels Labels) for deleting all metrics that match provided labels. #1013 <https://github.com/prometheus/client_golang/pull/1013> - [ENHANCEMENT] api.Config now accepts passing custom *http.Client. #1025 <https://github.com/prometheus/client_golang/pull/1025> - [BUGFIX] Raise exemplar labels limit from 64 to 128 bytes as specified in OpenMetrics spec. #1091 <https://github.com/prometheus/client_golang/pull/1091> - [BUGFIX] Allow adding exemplar to +Inf bucket to const histograms. #1094 <https://github.com/prometheus/client_golang/pull/1094> - [ENHANCEMENT] Most promhttp.Instrument* middlewares now support adding exemplars to metrics. This allows hooking those to your tracing middleware that retrieves trace ID and puts it in exemplar if present. #1055 <https://github.com/prometheus/client_golang/pull/1055> - [ENHANCEMENT] Added testutil.ScrapeAndCompare method. #1043 <https://github.com/prometheus/client_golang/pull/1043> - [BUGFIX] Fixed GopherJS build support. #897 <https://github.com/prometheus/client_golang/pull/897> - [ENHANCEMENT] ⚠️ Added way to specify what runtime/metrics collectors.NewGoCollector should use. See ExampleGoCollector_WithAdvancedGoMetrics <https://github.com/prometheus/client_golang/blob/v1.13.0/prometheus/collectors/go_collector_latest_test.go#L263> . #1102 <https://github.com/prometheus/client_golang/pull/1102> Kind Regards, Bartek Plotka (@bwplotka) -- You received this message because you are subscribed to the Google Groups "prometheus-announce" group.
