prometheus: update to 2.49.1.

2.49.1 / 2024-01-15 Latest

    [BUGFIX] TSDB: Fixed a wrong q= value in scrape accept header #13313

2.49.0 / 2024-01-15

    [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] TSDB: Various improvements to OOO exemplar scraping. E.g. \ 
allowing ingestion of exemplars with the same timestamp, but with different \ 
labels. #13021
    [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
    [BUGFIX] SD: Fixed Azure SD public IP reporting #13241
    [BUGFIX] API: Fix inaccuracies in posting cardinality statistics. #12653
    [BUGFIX] PromQL: Fix inaccuracies of histogram_quantile with classic \ 
histograms. #13153
    [BUGFIX] TSDB: Fix rare fails or inaccurate queries with OOO samples. #13115
    [BUGFIX] TSDB: Fix rare panics on append commit when exemplars are used. #13092
    [BUGFIX] TSDB: Fix exemplar WAL storage, so remote write can send/receive \ 
samples before exemplars. #13113
    [BUGFIX] Mixins: Fix url filter on remote write dashboards. #10721
    [BUGFIX] PromQL/TSDB: Various fixes to float histogram operations. #12891 \ 
#12977 #12609 #13190 #13189 #13191 #13201 #13212 #13208
    [BUGFIX] Promtool: Fix int32 overflow issues for 32-bit architectures. #12978
    [BUGFIX] SD: Fix Azure VM Scale Set NIC issue. #13283
