https://github.com/prometheus/prometheus - 3.0.0 / 2024-11-14

This release includes new features such as a brand new UI and UTF-8 support enabled by default. As this marks the first new major version in seven years, several breaking changes are introduced. The breaking changes are mainly around the removal of deprecated feature flags and CLI arguments, and the full list can be found below. For users that want to upgrade we recommend to read through our migration guide.

  • [CHANGE] Set the GOMAXPROCS variable automatically to match the Linux CPU quota. Use --no-auto-gomaxprocs to disable it. The auto-gomaxprocs feature flag was removed. #15376
  • [CHANGE] Set the GOMEMLIMIT variable automatically to match the Linux container memory limit. Use --no-auto-gomemlimit to disable it. The auto-gomemlimit feature flag was removed. #15373
  • [CHANGE] Scraping: Remove implicit fallback to the Prometheus text format in case of invalid/missing Content-Type and fail the scrape instead. Add ability to specify a fallback_scrape_protocol in the scrape config. #15136
  • [CHANGE] Remote-write: default enable_http2 to false. #15219
  • [CHANGE] Scraping: normalize "le" and "quantile" label values upon ingestion. #15164
  • [CHANGE] Scraping: config scrape_classic_histograms was renamed to always_scrape_classic_histograms. #15178
  • [CHANGE] Config: remove expand-external-labels flag, expand external labels env vars by default. #14657
  • [CHANGE] Disallow configuring AM with the v1 api. #13883
  • [CHANGE] regexp . now matches all characters (performance improvement). #14505
  • [CHANGE] holt_winters is now called double_exponential_smoothing and moves behind the experimental-promql-functions feature flag. #14930
  • [CHANGE] API: The OTLP receiver endpoint can now be enabled using --web.enable-otlp-receiver instead of --enable-feature=otlp-write-receiver. #14894
  • [CHANGE] Prometheus will not add or remove port numbers from the target address. no-default-scrape-port feature flag removed. #14160
  • [CHANGE] Logging: the format of log lines has changed a little, along with the adoption of Go's Structured Logging package. #14906
  • [CHANGE] Don't create extra _created timeseries if feature-flag created-timestamp-zero-ingestion is enabled. #14738
  • [CHANGE] Float literals and time durations being the same is now a stable fetaure. #15111
  • [CHANGE] UI: The old web UI has been replaced by a completely new one that is less cluttered and adds a few new features (PromLens-style tree view, better metrics explorer, "Explain" tab). However, it is still missing some features of the old UI (notably, exemplar display and heatmaps). To switch back to the old UI, you can use the feature flag --enable-feature=old-ui for the time being. #14872
  • [CHANGE] PromQL: Range selectors and the lookback delta are now left-open, i.e. a sample coinciding with the lower time limit is excluded rather than included. #13904
  • [CHANGE] Kubernetes SD: Remove support for discovery.k8s.io/v1beta1 API version of EndpointSlice. This version is no longer served as of Kubernetes v1.25. #14365
  • [CHANGE] Kubernetes SD: Remove support for networking.k8s.io/v1beta1 API version of Ingress. This version is no longer served as of Kubernetes v1.22. #14365
  • [CHANGE] UTF-8: Enable UTF-8 support by default. Prometheus now allows all UTF-8 characters in metric and label names. The corresponding utf8-name feature flag has been removed. #14705
  • [CHANGE] Console: Remove example files for the console feature. Users can continue using the console feature by supplying their own JavaScript and templates. #14807
  • [CHANGE] SD: Enable the new service discovery manager by default. This SD manager does not restart unchanged discoveries upon reloading. This makes reloads faster and reduces pressure on service discoveries' sources. The corresponding new-service-discovery-manager feature flag has been removed. #14770
  • [CHANGE] Agent mode has been promoted to stable. The feature flag agent has been removed. To run Prometheus in Agent mode, use the new --agent cmdline arg instead. #14747
  • [CHANGE] Remove deprecated remote-write-receiver,promql-at-modifier, and promql-negative-offset feature flags. #13456, #14526
  • [CHANGE] Remove deprecated storage.tsdb.allow-overlapping-blocks, alertmanager.timeout, and storage.tsdb.retention flags. #14640, #14643
  • [FEATURE] OTLP receiver: Ability to skip UTF-8 normalization using otlp.translation_strategy = NoUTF8EscapingWithSuffixes configuration option. #15384
  • [FEATURE] Support config reload automatically - feature flag auto-reload-config. #14769
  • [ENHANCEMENT] Scraping, rules: handle targets reappearing, or rules moving group, when out-of-order is enabled. #14710
  • [ENHANCEMENT] Tools: add debug printouts to promtool rules unit testing #15196
  • [ENHANCEMENT] Scraping: support Created-Timestamp feature on native histograms. #14694
  • [ENHANCEMENT] UI: Many fixes and improvements. #14898, #14899, #14907, #14908, #14912, #14913, #14914, #14931, #14940, #14945, #14946, #14972, #14981, #14982, #14994, #15096
  • [ENHANCEMENT] UI: Web UI now displays notifications, e.g. when starting up and shutting down. #15082
  • [ENHANCEMENT] PromQL: Introduce exponential interpolation for native histograms. #14677
  • [ENHANCEMENT] TSDB: Add support for ingestion of out-of-order native histogram samples. #14850, #14546
  • [ENHANCEMENT] Alerts: remove metrics for removed Alertmanagers. #13909
  • [ENHANCEMENT] Kubernetes SD: Support sidecar containers in endpoint discovery. #14929
  • [ENHANCEMENT] Consul SD: Support catalog filters. #11224
  • [ENHANCEMENT] Move AM discovery page from "Monitoring status" to "Server status". #14875
  • [PERF] TSDB: Parallelize deletion of postings after head compaction. #14975
  • [PERF] TSDB: Chunk encoding: shorten some write sequences. #14932
  • [PERF] TSDB: Grow postings by doubling. #14721
  • [PERF] Relabeling: Optimize adding a constant label pair. #12180
  • [BUGFIX] UI: fix selector / series formatting for empty metric names. #15341
  • [BUGFIX] PromQL: Fix stddev+stdvar aggregations to always ignore native histograms. #14941
  • [BUGFIX] PromQL: Fix stddev+stdvar aggregations to treat Infinity consistently. #14941
  • [BUGFIX] OTLP receiver: Preserve colons when generating metric names in suffix adding mode (this mode is always enabled, unless one uses Prometheus as a library). #15251
  • [BUGFIX] Scraping: Unit was missing when using protobuf format. #15095
  • [BUGFIX] PromQL: Only return "possible non-counter" annotation when rate returns points. #14910
  • [BUGFIX] TSDB: Chunks could have one unnecessary zero byte at the end. #14854
  • [BUGFIX] "superfluous response.WriteHeader call" messages in log. #14884
  • [BUGFIX] PromQL: Unary negation of native histograms. #14821
  • [BUGFIX] PromQL: Handle stale marker in native histogram series (e.g. if series goes away and comes back). #15025
  • [BUGFIX] Autoreload: Reload invalid yaml files. #14947
  • [BUGFIX] Scrape: Do not override target parameter labels with config params. #11029

New changes since v3.0.0-beta.1:

  • [CHANGE] Scraping: Remove implicit fallback to the Prometheus text format in case of invalid/missing Content-Type and fail the scrape instead. Add ability to specify a fallback_scrape_protocol in the scrape config. #15136
  • [CHANGE] Remote-write: default enable_http2 to false. #15219
  • [CHANGE] Scraping: normalize "le" and "quantile" label values upon ingestion. #15164
  • [CHANGE] Scraping: config scrape_classic_histograms was renamed to always_scrape_classic_histograms. #15178
  • [CHANGE] Config: remove expand-external-labels flag, expand external labels env vars by default. #14657
  • [CHANGE] Disallow configuring AM with the v1 api. #13883
  • [ENHANCEMENT] Scraping, rules: handle targets reappearing, or rules moving group, when out-of-order is enabled. #14710
  • [ENHANCEMENT] Tools: add debug printouts to promtool rules unit testing #15196
  • [ENHANCEMENT] Scraping: support Created-Timestamp feature on native histograms. #14694
  • [BUGFIX] PromQL: Fix stddev+stdvar aggregations to always ignore native histograms. #14941
  • [BUGFIX] PromQL: Fix stddev+stdvar aggregations to treat Infinity consistently. #14941
  • [BUGFIX] OTLP receiver: Preserve colons when generating metric names in suffix adding mode (this mode is always enabled, unless one uses Prometheus as a library). #15251

Changes from v3.0.0-beta.1 and v3.0.0-beta.0 are also included in this version.

Special release candidate build that incorporates performance improvements using the dedupelabels Go tag. The new labels data structure deduplicates label names and values via symbol or intern tables, trading off ~10% higher CPU usage for lower memory usage. Improves on 2.51.0+dedupelabels by squashing some leaks.

https://github.com/prometheus/prometheus - 3.0.0-beta.0 / 2024-09-05

Release 3.0.0-beta.0 includes new features such as a brand new UI and UTF-8 support enabled by default. As a new major version, several breaking changes are introduced. The breaking changes are mainly around the removal of deprecated feature flags and CLI arguments, and the full list can be found below. Most users should be able to try this release out of the box without any configuration changes.

As is traditional with a beta release, we do not recommend users install 3.0.0-beta on critical production systems, but we do want everyone to test it out and find bugs.

  • [CHANGE] UI: The old web UI has been replaced by a completely new one that is less cluttered and adds a few new features (PromLens-style tree view, better metrics explorer, "Explain" tab). However, it is still missing some features of the old UI (notably, exemplar display and heatmaps). To switch back to the old UI, you can use the feature flag --enable-feature=old-ui for the time being. #14872
  • [CHANGE] PromQL: Range selectors and the lookback delta are now left-open, i.e. a sample coinciding with the lower time limit is excluded rather than included. #13904
  • [CHANGE] Kubernetes SD: Remove support for discovery.k8s.io/v1beta1 API version of EndpointSlice. This version is no longer served as of Kubernetes v1.25. #14365
  • [CHANGE] Kubernetes SD: Remove support for networking.k8s.io/v1beta1 API version of Ingress. This version is no longer served as of Kubernetes v1.22. #14365
  • [CHANGE] UTF-8: Enable UTF-8 support by default. Prometheus now allows all UTF-8 characters in metric and label names. The corresponding utf8-name feature flag has been removed. #14705
  • [CHANGE] Console: Remove example files for the console feature. Users can continue using the console feature by supplying their own JavaScript and templates. #14807
  • [CHANGE] SD: Enable the new service discovery manager by default. This SD manager does not restart unchanged discoveries upon reloading. This makes reloads faster and reduces pressure on service discoveries' sources. The corresponding new-service-discovery-manager feature flag has been removed. #14770
  • [CHANGE] Agent mode has been promoted to stable. The feature flag agent has been removed. To run Prometheus in Agent mode, use the new --agent cmdline arg instead. #14747
  • [CHANGE] Remove deprecated remote-write-receiver,promql-at-modifier, and promql-negative-offset feature flags. #13456, #14526
  • [CHANGE] Remove deprecated storage.tsdb.allow-overlapping-blocks, alertmanager.timeout, and storage.tsdb.retention flags. #14640, #14643
  • [FEATURE] Promtool: Allow additional labels to be added to blocks created from openmetrics. #14402
  • [FEATURE] OTLP receiver: Add new option otlp.promote_resource_attributes, for any OTel resource attributes that should be promoted to metric labels. #14200
  • [FEATURE] Automatic reloading of the Prometheus configuration file at a specified interval #14769
  • [ENHANCEMENT] OTLP receiver: Warn when encountering exponential histograms with zero count and non-zero sum. #14706
  • [ENHANCEMENT] OTLP receiver: Interrupt translation on context cancellation/timeout. #14612
  • [ENHANCEMENT] Scrape: Only parse created timestamp if created-timestamp-zero-ingestion feature flag is enabled. This is as a lot of memory is used when parsing the created timestamp in the OM text format. #14815
  • [ENHANCEMENT] Scrape: Add support for logging scrape failures to a specified file. #14734
  • [ENHANCEMENT] Remote Read client: Enable streaming remote read if the server supports it. #11379
  • [ENHANCEMENT] PromQL: Delay deletion of __name__ label to the end of the query evaluation. This is experimental and enabled under the feature-flag promql-delayed-name-removal. #14477
  • [ENHANCEMENT] Move AM discovery page from "Monitoring status" to "Server status". #14875
  • [ENHANCEMENT] Tracing: Improve PromQL tracing, including showing the operation performed for aggregates, operators, and calls.#14816
  • [ENHANCEMENT] Add support for multiple listening addresses. #14665
  • [ENHANCEMENT] Add the ability to set custom HTTP headers. #14817
  • [BUGFIX] TSDB: Fix shard initialization after WAL repair. #14731
  • [BUGFIX] UTF-8: Ensure correct validation when legacy mode turned on. #14736
  • [BUGFIX] SD: Make discovery manager notify consumers of dropped targets for still defined jobs. #13147
  • [BUGFIX] SD: Prevent the new service discovery manager from storing stale targets. #13622
  • [BUGFIX] Remote Write 2.0: Ensure metadata records are sent from the WAL to remote write during WAL replay. #14766
  • [BUGFIX] Scrape: Do no override target parameter labels with config params. #11029
  • [BUGFIX] Scrape: Reset exemplar position when scraping histograms in protobuf. #14810
  • [BUGFIX] Native Histograms: Do not re-use spans between histograms. #14771
  • [BUGFIX] Scrape: Only parse created timestamp if created-timestamp-zero-ingestion feature flag is enabled. This is as a lot of memory is used when parsing the created timestamp in the OM text format. #14815
  • [BUGFIX] TSDB: Fix panic in query during truncation with OOO head. #14831
  • [BUGFIX] TSDB: Fix panic in chunk querier. #14874
  • [BUGFIX] promql.Engine.Close: No-op if nil. #14861
  • [BUGFIX] tsdb/wlog.Watcher.readSegmentForGC: Only count unknown record types against recorddecodefailures_total metric. #14042

https://github.com/prometheus/prometheus - 2.53.1 / 2024-07-10

This is a bug-fix release, reverting a change introduced in v2.51.0.

The bug was that remote-write would drop samples if the sending flow stalled for longer than it takes to write one "WAL segment". How long this takes depends on the data rate of your Prometheus; as a rough guide with 10 million series scraping once per minute it could be about 5 minutes. The issue is #14087.

  • [BUGFIX] Remote-write: stop dropping samples in catch-up #14446

https://github.com/prometheus/prometheus - 2.53.0 / 2024-06-16

This release changes the default for GOGC, the Go runtime control for the trade-off between excess memory use and CPU usage. We have found that Prometheus operates with minimal additional CPU usage, but greatly reduced memory by adjusting the upstream Go default from 100 to 75.

  • [CHANGE] Rules: Execute 1 query instead of N (where N is the number of alerts within alert rule) when restoring alerts. #13980 #14048
  • [CHANGE] Runtime: Change GOGC threshold from 100 to 75 #14176 #14285
  • [FEATURE] Rules: Add new option query_offset for each rule group via rule group configuration file and rule_query_offset as part of the global configuration to have more resilience for remote write delays. #14061 #14216 #14273
  • [ENHANCEMENT] Rules: Add rule_group_last_restore_duration_seconds metric to measure the time it takes to restore a rule group. #13974
  • [ENHANCEMENT] OTLP: Improve remote write format translation performance by using label set hashes for metric identifiers instead of string based ones. #14006 #13991
  • [ENHANCEMENT] TSDB: Optimize querying with regexp matchers. #13620
  • [BUGFIX] OTLP: Don't generate target_info unless there are metrics and at least one identifying label is defined. #13991
  • [BUGFIX] Scrape: Do no try to ingest native histograms when the native histograms feature is turned off. This happened when protobuf scrape was enabled by for example the created time feature. #13987
  • [BUGFIX] Scaleway SD: Use the instance's public IP if no private IP is available as the __address__ meta label. #13941
  • [BUGFIX] Query logger: Do not leak file descriptors on error. #13948
  • [BUGFIX] TSDB: Let queries with heavy regex matches be cancelled and not use up the CPU. #14096 #14103 #14118 #14199
  • [BUGFIX] API: Do not warn if result count is equal to the limit, only when exceeding the limit for the series, label-names and label-values APIs. #14116
  • [BUGFIX] TSDB: Fix head stats and hooks when replaying a corrupted snapshot. #14079

  • [FEATURE] Promtool: Add --run flag promtool test rules command. #12206
  • [FEATURE] SD: Add support for NS records to DNS SD. #13219
  • [FEATURE] UI: Add heatmap visualization setting in the Graph tab, useful histograms. #13096
  • [FEATURE] Scraping: Add scrape_config.enable_compression (default true) to disable gzip compression when scraping the target. #13166
  • [FEATURE] PromQL: Add a promql-experimental-functions feature flag containing some new experimental PromQL functions. #13103 NOTE: More experimental functions might be added behind the same feature flag in the future. Added functions:
    • Experimental mad_over_time (median absolute deviation around the median) function. #13059
    • Experimental sort_by_label and sort_by_label_desc functions allowing sorting returned series by labels. #11299
  • [FEATURE] SD: Add __meta_linode_gpus label to Linode SD. #13097
  • [FEATURE] API: Add exclude_alerts query parameter to /api/v1/rules to only return recording rules. #12999

We are working on some performance improvements in Prometheus, which are only built into Prometheus when compiling it using the Go tag stringlabels (therefore they are not shipped in the default binaries). It uses a data structure for labels that uses a single string to hold all the label/values, resulting in a smaller heap size and some speedups in most cases. We would like to encourage users who are interested in these improvements to help us measure the gains on their production architecture. We are providing release artefacts 2.43.0+stringlabels and Docker images tagged v2.43.0-stringlabels with those improvements for testing. #10991

We are working on some performance improvements in Prometheus, which are only built into Prometheus when compiling it using the Go tag stringlabels (therefore they are not shipped in the default binaries). It uses a data structure for labels that uses a single string to hold all the label/values, resulting in a smaller heap size and some speedups in most cases. We would like to encourage users who are interested in these improvements to help us measure the gains on their production architecture. Building Prometheus from source with the stringlabels Go tag and providing feedback on its effectiveness in their specific use cases would be incredibly helpful to us. #10991

https://github.com/prometheus/prometheus - 2.42.0 / 2023-01-31

This release comes with a bunch of feature coverage for native histograms and breaking changes.

If you are trying native histograms already, we recommend you remove the wal directory when upgrading. Because the old WAL record for native histograms is not backward compatible in v2.42.0, this will lead to some data loss for the latest data.

Additionally, if you scrape "float histograms" or use recording rules on native histograms in v2.42.0 (which writes float histograms), it is a one-way street since older versions do not support float histograms.

  • [ENHANCEMENT] Agent: Native histogram support. #11842
  • [ENHANCEMENT] Rules: Support native histograms in recording rules. #11838
  • [ENHANCEMENT] SD: Add container ID as a meta label for pod targets for Kubernetes. #11844
  • [ENHANCEMENT] SD: Add VM size label to azure service discovery. #11650
  • [ENHANCEMENT] Support native histograms in federation. #11830
  • [ENHANCEMENT] TSDB: Add gauge histogram support. #11783 #11840 #11814
  • [ENHANCEMENT] TSDB/Scrape: Support FloatHistogram that represents buckets as float64 values. #11522 #11817 #11716
  • [ENHANCEMENT] UI: Show individual scrape pools on /targets page. #11142
