⚠️ This release contains potential breaking change if you upgrade github.com/prometheus/common to 0.62+ together with client_golang (and depend on the strict, legacy validation for the label names). New common version changes model.NameValidationScheme global variable, which relaxes the validation of label names and metric name, allowing all UTF-8 characters. Typically, this should not break any user, unless your test or usage expects strict certain names to panic/fail on client_golang metric registration, gathering or scrape. In case of problems change model.NameValidationScheme to old model.LegacyValidation value in your project init function. ⚠️

  • [BUGFIX] gocollector: Fix help message for runtime/metric metrics. #​1583
  • [BUGFIX] prometheus: Fix Desc.String() method for no labels case. #​1687
  • [PERF] prometheus: Optimize popular prometheus.BuildFQName function; now up to 30% faster. #​1665
  • [PERF] prometheus: Optimize Inc, Add and Observe cumulative metrics; now up to 50% faster under high concurrent contention. #​1661
  • [CHANGE] Upgrade prometheus/common to 0.62.0 which changes model.NameValidationScheme global variable. #​1712
  • [CHANGE] Add support for Go 1.23. #​1602
  • [FEATURE] process_collector: Add support for Darwin systems. #​1600 #​1616 #​1625 #​1675 #​1715
  • [FEATURE] api: Add ability to invoke CloseIdleConnections on api.Client using api.Client.(CloseIdler).CloseIdleConnections() casting. #​1513
  • [FEATURE] promhttp: Add promhttp.HandlerOpts.EnableOpenMetricsTextCreatedSamples option to create OpenMetrics _created lines. Not recommended unless you want to use opt-in Created Timestamp feature. Community works on OpenMetrics 2.0 format that should make those lines obsolete (they increase cardinality significantly). #​1408
  • [FEATURE] prometheus: Add NewConstNativeHistogram function. #​1654

v1.20.5: / 2024-10-15

Compare Source

We decided to revert the testutil change that made our util functions less error-prone, but created a lot of work for our downstream users. Apologies for the pain! This revert should not cause any major breaking change, even if you already did the work--unless you depend on the exact error message.

Going forward, we plan to reinforce our release testing strategy [1],[2] and deliver an enhanced testutil package/module with more flexible and safer APIs.

Thanks to @​dashpole @​dgrisonnet @​kakkoyun @​ArthurSens @​vesari @​logicalhan @​krajorama @​bwplotka who helped in this patch release! 🤗

v1.20.0

Compare Source

Thanks everyone for contributions!

⚠️ In this release we remove one (broken anyway, given Go runtime changes) metric and add three new (representing GOGC, GOMEMLIMIT and GOMAXPROCS flags) to the default collectors.NewGoCollector() collector. Given its popular usage, expect your binary to expose two additional metric.

Changes

  • [CHANGE] ⚠️ go-collector: Remove go_memstat_lookups_total metric which was always 0; Go runtime stopped sharing pointer lookup statistics. #​1577
  • [FEATURE] ⚠️ go-collector: Add 3 default metrics: go_gc_gogc_percent, go_gc_gomemlimit_bytes and go_sched_gomaxprocs_threads as those are recommended by the Go team. #​1559
  • [FEATURE] go-collector: Add more information to all metrics' HELP e.g. the exact runtime/metrics sourcing each metric (if relevant). #​1568 #​1578
  • [FEATURE] testutil: Add CollectAndFormat method. #​1503
  • [FEATURE] histograms: Add support for exemplars in native histograms. #​1471
  • [FEATURE] promhttp: Add experimental support for zstd on scrape, controlled by the request Accept-Encoding header. #​1496
  • [FEATURE] api/v1: Add WithLimit parameter to all API methods that supports it. #​1544
  • [FEATURE] prometheus: Add support for created timestamps in constant histograms and constant summaries. #​1537
  • [FEATURE] process-collectors: Add network usage metrics: process_network_receive_bytes_total and process_network_transmit_bytes_total. #​1555
  • [FEATURE] promlint: Add duplicated metric lint rule. #​1472
  • [BUGFIX] promlint: Relax metric type in name linter rule. #​1455
  • [BUGFIX] promhttp: Make sure server instrumentation wrapping supports new and future extra responseWriter methods. #​1480
  • [BUGFIX] testutil: Functions using compareMetricFamilies are now failing if filtered metricNames are not in the input. #​1424
