prometheus: update to 2.53.1. ## 2.53.1 / 2024-07-10 Fix a bug which would drop samples in remote-write if the sending flow stalled for longer than it takes to write one "WAL segment". How long this takes depends on the size of your Prometheus; as a rough guide with 10 million series it is about 2-3 minutes. * [BUGFIX] Remote-write: stop dropping samples in catch-up #14446
prometheus: update to 2.53.0. ## 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
prometheus: update to 2.52.1. ## 2.52.1 / 2024-05-29 * [BUGFIX] Linode SD: Fix partial fetch when discovery would return more than 500 elements. #14141

prometheus: update to 2.51.1. ## 2.51.1 / 2024-03-27 Bugfix release. * [BUGFIX] PromQL: Re-instate validation of label_join destination label #13803 * [BUGFIX] Scraping (experimental native histograms): Fix handling of the min bucket factor on sync of targets #13846 * [BUGFIX] PromQL: Some queries could return the same series twice (library use only) #13845 ## 2.51.0 / 2024-03-18 This version is built with Go 1.22.1. There is a new optional build tag "dedupelabels", which should reduce memory consumption (#12304). It is off by default; there will be an optional alternative image to try it out. * [CHANGE] Scraping: Do experimental timestamp alignment even if tolerance is bigger than 1% of scrape interval #13624, #13737 * [FEATURE] Alerting: Relabel rules for AlertManagerConfig; allows routing alerts to different alertmanagers #12551, #13735 * [FEATURE] API: add limit param to series, label-names and label-values APIs #13396 * [FEATURE] UI (experimental native histograms): Add native histogram chart to Table view #13658 * [FEATURE] Promtool: Add a "tsdb dump-openmetrics" to dump in OpenMetrics format. #13194 * [FEATURE] PromQL (experimental native histograms): Add histogram_avg function #13467 * [ENHANCEMENT] Rules: Evaluate independent rules concurrently #12946, #13527 * [ENHANCEMENT] Scraping (experimental native histograms): Support exemplars #13488 * [ENHANCEMENT] Remote Write: Disable resharding during active retry backoffs #13562 * [ENHANCEMENT] Observability: Add native histograms to latency/duration metrics #13681 * [ENHANCEMENT] Observability: Add 'type' label to prometheus_tsdb_head_out_of_order_samples_appended_total #13607 * [ENHANCEMENT] API: Faster generation of targets into JSON #13469, #13484 * [ENHANCEMENT] Scraping, API: Use faster compression library #10782 * [ENHANCEMENT] OpenTelemetry: Performance improvements in OTLP parsing #13627 * [ENHANCEMENT] PromQL: Optimisations to reduce CPU and memory #13448, #13536 * [BUGFIX] PromQL: Constrain extrapolation in rate() to half of sample interval #13725 * [BUGFIX] Remote Write: Stop slowing down when a new WAL segment is created #13583, #13628 * [BUGFIX] PromQL: Fix wrongly scoped range vectors with @ modifier #13559 * [BUGFIX] Kubernetes SD: Pod status changes were not discovered by Endpoints service discovery #13337 * [BUGFIX] Azure SD: Fix 'error: parameter virtualMachineScaleSetName cannot be empty' (#13702) * [BUGFIX] Remote Write: Fix signing for AWS sigv4 transport #13497 * [BUGFIX] Observability: Exemplars emitted by Prometheus use "trace_id" not "traceID" #13589

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 * [FEATURE] Promtool: Add HTTP client configuration to query commands. #11487 * [FEATURE] Scrape: Add `scrape_config_files` to include scrape configs from different files. #12019 * [FEATURE] HTTP client: Add `no_proxy` to exclude URLs from proxied requests. #12098 * [FEATURE] HTTP client: Add `proxy_from_environment` to read proxies from env variables. #12098 * [ENHANCEMENT] API: Add support for setting lookback delta per query via the API. #12088 * [ENHANCEMENT] API: Change HTTP status code from 503/422 to 499 if a request is canceled. #11897 * [ENHANCEMENT] Scrape: Allow exemplars for all metric types. #11984 * [ENHANCEMENT] TSDB: Add metrics for head chunks and WAL folders size. #12013 * [ENHANCEMENT] TSDB: Automatically remove incorrect snapshot with index that is ahead of WAL. #11859 * [ENHANCEMENT] TSDB: Improve Prometheus parser error outputs to be more comprehensible. #11682 * [ENHANCEMENT] UI: Scope `group by` labels to metric in autocompletion. #11914 * [BUGFIX] Scrape: Fix `prometheus_target_scrape_pool_target_limit` metric not set before reloading. #12002 * [BUGFIX] TSDB: Correctly update `prometheus_tsdb_head_chunks_removed_total` and `prometheus_tsdb_head_chunks` metrics when reading WAL. #11858 * [BUGFIX] TSDB: Use the correct unit (seconds) when recording out-of-order append deltas in the `prometheus_tsdb_sample_ooo_delta` metric. #12004 ## 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. * [CHANGE] **breaking** TSDB: Changed WAL record format for the experimental native histograms. #11783 * [FEATURE] Add 'keep_firing_for' field to alerting rules. #11827 * [FEATURE] Promtool: Add support of selecting timeseries for TSDB dump. #11872 * [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 ## 2.41.0 / 2022-12-20 * [FEATURE] Relabeling: Add `keepequal` and `dropequal` relabel actions. #11564 * [FEATURE] Add support for HTTP proxy headers. #11712 * [ENHANCEMENT] Reload private certificates when changed on disk. #11685 * [ENHANCEMENT] Add `max_version` to specify maximum TLS version in `tls_config`. #11685 * [ENHANCEMENT] Add `goos` and `goarch` labels to `prometheus_build_info`. #11685 * [ENHANCEMENT] SD: Add proxy support for EC2 and LightSail SDs #11611 * [ENHANCEMENT] SD: Add new metric `prometheus_sd_file_watcher_errors_total`. #11066 * [ENHANCEMENT] Remote Read: Use a pool to speed up marshalling. #11357 * [ENHANCEMENT] TSDB: Improve handling of tombstoned chunks in iterators. #11632 * [ENHANCEMENT] TSDB: Optimize postings offset table reading. #11535 * [BUGFIX] Scrape: Validate the metric name, label names, and label values after relabeling. #11074 * [BUGFIX] Remote Write receiver and rule manager: Fix error handling. #11727 ## 2.40.7 / 2022-12-14 * [BUGFIX] Use Windows native DNS resolver. #11704 * [BUGFIX] TSDB: Fix queries involving negative buckets of native histograms. #11699 ## 2.40.6 / 2022-12-09 * [SECURITY] Security upgrade from go and upstream dependencies that include security fixes to the net/http and os packages. #11691
