v0.79.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.79.0 and the opentelemetry-collector-contrib v0.79.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Contrib) Set pkg.translator.prometheus.NormalizeName feature gate back to Alpha state since it was enabled
  prematurely. Metrics coming from Prometheus receiver will not be normalized by default, specifically _total suffix
  will not be removed from metric names. To maintain the current behavior (drop the _total suffix), you can enable
  the feature gate using the --feature-gates=pkg.translator.prometheus.NormalizeName command argument. However, note
  that the translation in the prometheus receiver is a subject to possible future changes.
  (#23229)
• (Contrib) attributesprocessor: Enable SHA-256 as hashing algorithm by default for attributesprocessor hashing action (#4759)
• (Contrib) windowseventlogreceiver: Emit raw Windows events as strings instead of byte arrays (#22704)
• (Contrib) 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.
• (Contrib) postgresqlreceiver: Remove resource attribute feature gates (#22479)

💡 Enhancements 💡

• (Splunk) smartagentreceiver: Add kubernetes-cluster config option to sync node labels as properties on the kubernetes_node dimension (#3267)
• (Splunk) Discovery mode: Support splunk.discovery mapping in properties.discovery.yaml (#3238)
• (Splunk) Upgrade to the latest Java agent version v1.25.0 (#3272)
• (Contrib) jmxreceiver: Add the JMX metrics gatherer version 1.26.0-alpha to the supported jars hash list (#22042)
• (Contrib) receivers: Adding initial_delay to receivers to control when scraping interval starts (#23030)
  The updated receivers are:
  • oracledb
  • postgresql
  • sqlquery
  • windowsperfcounters
• (Contrib) oracledbreceiver: Add a simpler alternative configuration option (#22087)
• (Contrib) pkg/ottl: Add body.string accessor to ottllog (#22786)
• (Contrib) pkg/ottl: Allow indexing map and slice log bodies (#17396, #22068)
• (Contrib) pkg/ottl: Add hash converters/functions for OTTL (#22725)
• (Contrib) splunkhecreceiver: Support different strategies for splitting payloads when receiving a request with the Splunk HEC receiver (#22788)
• (Contrib) 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.
• (Core) otelcol: Add connectors to output of the components command (#7809)
• (Core) scraperhelper: Will start calling scrapers on component start. (#7635)
  The change allows scrapes to perform their initial scrape on component start
  and provide an initial delay. This means that scrapes will be delayed by initial_delay
  before first scrape and then run on collection_interval for each consecutive interval.
• (Core) batchprocessor: Change multiBatcher to use sync.Map, avoid global lock on fast path (#7714)
• (Core, Contrib, Splunk) Third-party dependency updates.

🧰 Bug fixes 🧰

• (Splunk) smartagentreceiver add missing monitorID logger field to http monitor (#3261)
• (Contrib) jmxreceiver: Fixed the issue where the JMX receiver's subprocess wasn't canceled upon shutdown, resulting in a rogue java process. (#23051)
• (Contrib) internal/filter/filterlog: fix filtering non-string body by bodies property (#22736)
  Affects filterprocessor and attributesprocessor.
• (Contrib) 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)
• (Contrib) fileexporter: Fixes broken lines when rotation is set. (#22747)
• (Contrib) 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)
• (Contrib) postgresqlreceiver: Fix race condition when capturing errors from multiple requests simultaneously (#23026)
• (Contrib) prometheusreceiver: The prometheus receiver now sets a full, versioned user agent. (#21910)
• (Contrib) splunkhecreceiver: Fix reusing the same splunkhecreiver between logs and metrics (#22848)
• (Core) connectors: When replicating data to connectors, consider whether the next pipeline will mutate data (#7776)
