1.12.2 / 2022-05-13

• [CHANGE] Added collectors.WithGoCollections that allows to choose what collection of Go runtime metrics user wants: Equivalent of MemStats structure configured using GoRuntimeMemStatsCollection, new based on dedicated runtime/metrics metrics represented by GoRuntimeMetricsCollection option, or both by specifying GoRuntimeMemStatsCollection | GoRuntimeMetricsCollection flag.
• [CHANGE] ⚠️ Change in collectors.NewGoCollector metrics: Reverting addition of new ~80 runtime metrics by default. You can enable this back with GoRuntimeMetricsCollection option or GoRuntimeMemStatsCollection | GoRuntimeMetricsCollection for smooth transition.
• [BUGFIX] Fixed the bug that causes generated histogram metric names to end with _total. ⚠️ This changes 3 metric names in the new Go collector that was reverted from default in this release.
  • go_gc_heap_allocs_by_size_bytes_total -> go_gc_heap_allocs_by_size_bytes,
  • go_gc_heap_frees_by_size_bytes_total -> go_gc_heap_allocs_by_size_bytes
  • go_gc_pauses_seconds_total -> go_gc_pauses_seconds.
• [CHANGE] Removed -Inf buckets from new Go Collector histograms.
