Prometheus - v2.49.0

  • [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 #13371
  • [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
  • [FEATURE] TSDB: --storage.tsdb.retention.time flag value is now exposed as a prometheus_tsdb_retention_limit_seconds metric. #12986
  • [FEATURE] Scraping: Add ability to specify priority of scrape protocols to accept during scrape (e.g. to scrape Prometheus proto format for certain jobs). This can be changed by setting global.scrape_protocols and scrape_config.scrape_protocols. #12738
  • [ENHANCEMENT] Scraping: Automated handling of scraping histograms that violate scrape_config.native_histogram_bucket_limit setting. #13129
  • [ENHANCEMENT] Scraping: Optimized memory allocations when scraping. #12992
  • [ENHANCEMENT] SD: Added cache for Azure SD to avoid rate-limits. #12622

  • [ENHANCEMENT] API: Optimize /api/v1/labels and /api/v1/label/<label_name>/values when 1 set of matchers are used. #12888
  • [ENHANCEMENT] TSDB: Various optimizations for TSDB block index, head mmap chunks and WAL, reducing latency and memory allocations (improving API calls, compaction queries etc). #12997 #13058 #13056 #13040
  • [ENHANCEMENT] PromQL: Optimize memory allocations and latency when querying float histograms. #12954
  • [ENHANCEMENT] Rules: Instrument TraceID in log lines for rule evaluations. #13034
  • [ENHANCEMENT] PromQL: Optimize memory allocations in query_range calls. #13043
  • [ENHANCEMENT] Promtool: unittest interval now defaults to evaluation_intervals when not set. #12729
