v0.111.0

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

🆕 The binary release adds a new OTLP-only distro. Feel free to leave us feedback on this new distro on the opentelemetry-collector-releases issue tracker.

⚠️ The core release removes the logging exporter. See open-telemetry/opentelemetry-collector#11337 for instructions on how to migrate to the debug exporter.

End User Changelog

🛑 Breaking changes 🛑

• instanaexporter: Remove deprecated instanaexporter (#35367)
  Use the otlp exporter instead as explained in IBM's documentation.
• elasticsearchexporter: Drop cumulative temporality histogram and exponential histogram (#35442)
  Cumulative temporality histogram and exponential histogram are not supported by Elasticsearch. Use cumulativetodeltaprocessor to convert cumulative temporality to delta temporality.
• elasticsearchexporter: Implement receiver-based routing under *_dynamic_index config (#34246)
• config: Move component.UseLocalHostAsDefaultHost feature gate to stable. (#35569)
• metricsgenerationprocessor: Generate metrics even when the second metric's value is 0 (#35533)
• signalfxexporter: Do not exclude the metric container.memory.working_set (#35475)
• sqlqueryreceiver: Fail if value for log column in result set is missing, collect errors (#35068)
• windowseventlogreceiver: The 'raw' flag no longer suppresses rendering info. (#34720)
  Previously, this flag controlled two behaviors simultaneously:
  1. Whether or not the body of the log record was an XML string or structured object.
  2. Whether or not rendering info was resolved.
     A separate 'suppress_rendering_info' option now controls rendering info resolution.
     This is considered a breaking change because users setting only the 'raw' flag without also setting the
     new 'suppress_rendering_info' flag may see a performance decrease along with more detailed events.

🚩 Deprecations 🚩

• sapmreceiver: access_token_passthrough is deprecated (#35330)
  • "access_token_passthrough is deprecated."
  • "Please enable include_metadata in the receiver and add the following config to the batch processor:"

  batch:
    metadata_keys: [X-Sf-Token]

🚀 New components 🚀

• receiver/prometheusremotewrite: Add a new receiver for Prometheus Remote Write.
  (#33782)

💡 Enhancements 💡

• sumconnector: adds connector and summing logic along with tests (#32669)

• receivercreator: Validate endpoint's configuration before starting receivers (#33145)

• otelarrowreceiver: Add admission control in the otelarrow receiver's standard otlp data path.
  Also moves admission control config options to a separate block.
  arrow.admission_limit_mib -> admission.request_limit_mib
  arrow.waiter_limit -> admission.waiter_limit
  (#35021)

• clickhouseexporter: Upgrading stability for traces to beta (#35186)
  The trace exporter has proven to be stable for production deployments.
  Trace configuration is unlikely to receive any significant changes.

• clickhouseexporter: Updated the default trace table (#34245)
  Reduced data types, improved partitioning and time range queries

• opampsupervisor: Add configurable logging for the supervisor. (#35466)

• datadogreceiver: Move receiver's metrics stability to alpha. (#18278)

• datadogreceiver: Add container id from v0.5 request header (#35345)

• elasticsearchexporter: Implement elasticsearch.mapping.hints attribute handling for data points in OTel mapping mode (#35479)
  elasticsearch.mapping.hints takes a slice of strings. _doc_count enables emitting _doc_count for the document. aggregate_metric_double causes histogram or exponential histogram to be emitted as aggregate_metric_double.

• elasticsearchexporter: Revert TSDB array dimension workaround for metrics OTel mode (#35291)
  Remove the workaround to stringify array dimensions as the limitation has been lifted in Elasticsearch v8.16.0.

• receiver/statsd: Add support for aggregating on Host/IP.
  (#23809)

• opampsupervisor: Skip executing the collector if no config is provided (#33680)

• googlecloudmonitoringreceiver: Move receiver's stability to alpha. (#33762)

• hostmetricsreceiver: Add ability to mute all errors (mainly due to access rights) coming from process scraper of the hostmetricsreceiver (#20435)

• kubeletstats: Introduce feature gate for deprecation of container.cpu.utilization, k8s.pod.cpu.utilization and k8s.node.cpu.utilization metrics (#35139)

• opampsupervisor: Make supervisor runnable as a Windows Service. (#34774)

• opampsupervisor: Add config option for setting the timeout for the initial bootstrap information retrieval from the agent (#34996)

• pkg/ottl: Add InsertXML Converter (#35436)

• pkg/ottl: Add GetXML Converter (#35462)

• pkg/ottl: Add ToKeyValueString Converter (#35334)

• pkg/ottl: Add RemoveXML Converter (#35301)

• geoipprocessor: No longer return an error when geo metadata is not found by a provider. (#35047)

• sqlserverreceiver: Add computer name resource attribute to relevant metrics (#35040)

• windowseventlogreceiver: Add 'suppress_rendering_info' option. (#34720)
  When this flag is enabled, the receiver will not attempt to resolve rendering info. This can improve performance
  but comes at a cost of losing some details in the event log.

• windowseventlogreceiver: Move artificial "remote_server" field to 'attributes["server.address"]'. (#34720)

🧰 Bug fixes 🧰

• webhookeventreceiver: Fixed a bug where request bodies containing newline characters caused the results to split into multiple log entries (#35028)
• opampsupervisor: Only use TLS config when connecting to OpAMP server if using wss or https protocols. (#35283)
• metricsgenerationprocessor: Allow metric calculations to be done on sum metrics (#35428)
• sqlqueryreceiver: Fix reprocessing of logs when tracking_column type is timestamp (#35194)
• windowseventlogreceiver: While collecting from a remote windows host, the stanza operator will no longer log "subscription handle is already open" constantly during successful collection. (#35520)
• windowseventlogreceiver: If collecting from a remote host, the receiver will stop collecting if the host restarts. This change resubscribes when the host restarts. (#35175)
