v0.79.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release, be sure to check the release notes there as well.

🛑 Breaking changes 🛑

• attributesprocessor: Enable SHA-256 as hashing algorithm by default for attributesprocessor hashing action (#4759)
• windowseventlogreceiver: Emit raw Windows events as strings instead of byte arrays (#22704)
• receiver/httpcheck: Removed the default endpoint value of http://localhost:80. The endpoint property is now required. (#22995)
• pkg/ottl: Removes StandardTypeGetter in favor of StandardStringGetter, StandardIntGetter, StandardFloatGetter, and StandardPMapGetter, which handle converting pcommon.Values of the proper type. (#22763)
  This is only a breaking change for users using OTTL in custom components. For all Contrib components this is an enhancement.
• postgresqlreceiver: Remove resource attribute feature gates (#22479)

🚩 Deprecations 🚩

• dockerstatsreceiver: cpu.container.percent metric will be deprecated in v0.79.0 in favor of container.cpu.utilization (#21807)
  This starts the process of phasing out incorrect metric name:
  • container.cpu.utilization
    and replacing it with the names adhering to the semantic conventions:
  • container.cpu.percent
    At this stage, the new metric is added, but is disabled by default.
    See the "Deprecations" section of the Docker Stats receiver's README for details.

💡 Enhancements 💡

  The updated receivers are:

  • active_directory_ds

  • apache
  • apachespark
  • azuremonitor
  • couchdb
  • chrony
  • docker_stats
  • elasticsearch
  • expvar
  • filestats

  • postgresql
  • rabbitmq
  • riak
  • snowflake
  • sqlquery
  • sqlserver
  • sshcheck
  • vcenter

  • zookeeper

• oracledbreceiver: Add a simpler alternative configuration option (#22087)

• exporter/datadog: Upgrade opentelemetry-mapping-go to v0.3.0 and use pkg/otlp/logs for logs translation (#23137)

• pkg/ottl: Add body.string accessor to ottllog (#22786)

• pkg/ottl: Allow indexing map and slice log bodies (#17396, #22068)

• pkg/ottl: Add hash converters/functions for OTTL (#22725)

• solacereceiver: Updated solacereceiver to handle new features of Solace PubSub+ 10.4.1 (#22809)

• splunkhecreceiver: Support different strategies for splitting payloads when receiving a request with the Splunk HEC receiver. (#22788)

• exporter/splunk_hec: Apply compression to Splunk HEC payload unconditionally if it's enabled in the config. (#22969, #22018)
  The compression used to be enabled only if the payload size was greater than 1.5KB which significantly
  complicated the logic and made it hard to test. This change makes the compression unconditionally applied to
  the payload if it's enabled in the config. The benchmarking shows improvements in the throughput and CPU usage for
  large payloads and expected degradation for small payloads which is acceptable given that it's not a common case.

• awsxrayexporter: Support 2 new aws service name attributes for populating X-Ray segment name (#22835)

🧰 Bug fixes 🧰

• jmxreceiver: Fixed the issue where the JMX receiver's subprocess wasn't canceled upon shutdown, resulting in a rogue java process. (#23051)

• internal/filter/filterlog: fix filtering non-string body by bodies property (#22736)
  Affects filterprocessor and attributesprocessor.

• prometheusreceiver: Remove sd_file validations from config.go in Prometheus Receiver to avoid failing Collector with error as this behaviour is incompatible with the Prometheus. (#21509)

• filelogreceiver: Fix issue where empty files would not be skipped, resulting in extraneous errors. (#22815)

• servicegraphprocessor: consume traces even metric count is equal to 0 (#23028)

• fileexporter: Fixes broken lines when rotation is set. (#22747)

• receiver/purefareceiver: Ensure that all endpoints beyond volumes and hosts are beeing scraped. (#14886)

• exporter/datadog: tls::insecure_skip_verify is now honored when exporting traces. (#22772)

• exporter/splunk_hec: Make sure the max_event_size option is used to drop events larger than max_event_size instead of using it for batch size. (#18066)

• httpcheckreceiver: Update default collection interval to match documented value (#23019)

• azuredataexplorerexporter: Update underlying SDK to perform retries on init on machines with flaky networks. (#22771)

• flink metrics receiver: Fixed error when failing to read job manager metrics (#23143)

• apache receiver: reverted default collection time back to 10s from 1m (#23030)

• postgresqlreceiver: Fix race condition when capturing errors from multiple requests simultaneously (#23026)

• prometheusreceiver: The prometheus receiver now sets a full, versioned user agent. (#21910)

• awscloudwatchreceiver: Fixes a bug where the AWS CloudWatch receiver does the log stream filtering (using prefix) incorrectly. (#22123)
  An additional request was being made with a single log stream prefix definition.
  This request was made with the stream name set to "".
  This results in logs collection from all log streams in the log group.

• spanmetricsconnector: Fix initialization of the default histogram buckets when the seconds unit is provided. (#21797)

• splunkhecreceiver: Fix reusing the same splunkhecreiver between logs and metrics (#22848)
