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

What's Changed

The module prometheus/common v0.48.0 introduced an incompatibility when used together with client_golang (See https://github.com/prometheus/client_golang/pull/1448 for more details). If your project uses client_golang and you want to use prometheus/common v0.48.0 or higher, please update client_golang to v1.19.0.

• [CHANGE] Minimum required go version is now 1.20 (we also test client_golang against new 1.22 version). #​1445 #​1449
