End User Changes

🛑 Breaking changes 🛑

• podmanreceiver: Adds metrics and resources metadata and sets seconds precision for cpu metrics (#28640)

• clickhouseexporter: Add ServiceName as column into Clickhouse metrics tables (#31670)
  It's a breaking change. users who upgrade to the latest version need to alter the Clickhouse table:

  ALTER TABLE otel_metrics_exponential_histogram ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_gauge ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_histogram ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_sum ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_summary ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));

• elasticsearchexporter: Initial pass in implementing the ecs mapping mode (#31553)
  Breaking change if mapping mode is set to ecs, use none to maintain existing format

• pkg/stanza: Revert recombine operator's 'overwrite_with' default value. (#30783)
  Restores the previous the default value of oldest, meaning that the recombine operator will emit the
  first entry from each batch (with the recombined field). This fixes the bug introduced by 30783 and restores
  the default setting so as to effectively cancel out the bug for users who were not using this setting.
  For users who were explicitly setting overwrite_with, this corrects the intended behavior.

• processor/attributes, processor/resource: Remove stable coreinternal.attraction.hash.sha256 feature gate. (#31997)

• receiver/dockerstats: Remove stable receiver.dockerstats.useScraperV2 feature gate. (#31999)

• awsxrayexporter: change x-ray exporter's translator to make "." split annotation pass as-is (#31732)
  In the past, X-Ray doesn’t support “.”. So we have a translator in x-ray export to translates it to “_” before sending traces to X-Ray Service. | To match otel naming style, x-ray service team decide to change their service to support both "." type and "" type of naming. In this case the translator that translate "." to "" is no-longer needed. This PR change the way this translator work | X-Ray PMs agree on rolling out this change by using feature-gate

🚩 Deprecations 🚩

• postgresqlreceiver: Minimal supported PostgreSQL version will be updated from 9.6 to 12.0 in a future release. (#30923)
  Aligning on the supported versions as can be seen in the PostgreSQL releases section

🚀 New components 🚀

• avrologencodingextension: Add new encoding extension to support mapping of AVRO messages to logs. (#21067)

💡 Enhancements 💡

• ottl: Add new Unix function to convert from epoch timestamp to time.Time (#27868)

• filelogreceiver: When reading a file on filelogreceiver not on windows, if include_file_owner_name is true, it will add the file owner name as the attribute log.file.owner.name and if include_file_owner_group_name is true, it will add the file owner group name as the attribute log.file.owner.group.name. (#30775)

• awsproxyextension: Make awsproxy extension more resilient by initiating the AWS client during Start. (#27849)

• deltatocumulativeprocessor: self-instrumentation to observe key metrics of the stream accumulation (#30705)

• datadog/connector: Enable connector to use any attribute from the resource as Container Tag (#32224)
  This change allows the connector to use any attribute from the resource as a container tag. This is useful when you want to use a custom attribute from the resource as a container tag. For example, you can use the namespace attribute from the resource as a container tag.

• exceptionsconnector: change stability of exceptionsconnector from development to alpha (#31820)

• exceptionsconnector: Copy span attributes to the generated log from exception. (#24410)

• prometheusreceiver: Allows receiving prometheus native histograms (#26555)

  • Native histograms are compatible with OTEL exponential histograms.
  • The feature can be enabled via the feature gate receiver.prometheusreceiver.EnableNativeHistograms.
    Run the collector with the command line option --feature-gates=receiver.prometheusreceiver.EnableNativeHistograms.
  • Currently the feature also requires that targets are scraped via the ProtoBuf format.
    To start scraping native histograms, set
    config.global.scrape_protocols to [ PrometheusProto, OpenMetricsText1.0.0, OpenMetricsText0.0.1, PrometheusText0.0.4 ] in the
    receiver configuration. This requirement will be lifted once Prometheus can scrape native histograms over text formats.
  • For more up to date information see the README.md file of the receiver at
    https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/prometheusreceiver/README.md#prometheus-native-histograms.
