🛑 Breaking changes 🛑

• vcenterreceiver: Enables various vCenter metrics that were disabled by default until v0.106.0 (#​33607)
  The following metrics will be enabled by default "vcenter.datacenter.cluster.count", "vcenter.datacenter.vm.count", "vcenter.datacenter.datastore.count",
  "vcenter.datacenter.host.count", "vcenter.datacenter.disk.space", "vcenter.datacenter.cpu.limit", "vcenter.datacenter.memory.limit",
  "vcenter.resource_pool.memory.swapped", "vcenter.resource_pool.memory.ballooned", and "vcenter.resource_pool.memory.granted". The
  "resourcePoolMemoryUsageAttribute" has also been bumped up to release v.0.107.0

• googlemanagedprometheusexporter: Fix typo in exporter.googlemanagedpromethues.intToDouble feature gate (#​34232)

🚩 Deprecations 🚩

• k8sattributesprocessor: Deprecate extract.annotations.regex and extract.labels.regex config fields in favor of the ExtractPatterns function in the transform processor. The FieldExtractConfig.Regex parameter will be removed in version v0.111.0. (#​25128)
  Deprecating of FieldExtractConfig.Regex parameter means that it is recommended to use the ExtractPatterns function from the transform processor instead. To convert your current configuration please check the ExtractPatterns function documentation. You should use the pattern parameter of ExtractPatterns instead of using the FieldExtractConfig.Regex parameter.

🚀 New components 🚀

• otlpjsonconnector: New component that will allow extracting otlpjson data from incoming Logs. (#​34239, #​34208)
• redis_storage: Adds a new storage extension using Redis to store data in transit (#​31682)

💡 Enhancements 💡

• processor/transform: Add scale_metric function that scales all data points in a metric. (#​16214)

• vcenterreceiver: Adds vCenter vSAN host metrics. (#​33556)
  Introduces the following vSAN host metrics to the vCenter receiver:

  • vcenter.host.vsan.throughput
  • vcenter.host.vsan.iops
  • vcenter.host.vsan.congestions
  • vcenter.host.vsan.cache.hit_rate
  • vcenter.host.vsan.latency.avg

• transformprocessor: Support aggregating metrics based on their attributes. (#​16224)

• metricstransformprocessor: Adds the 'median' aggregation type to the Metrics Transform Processor. Also uses the refactored aggregation business logic from internal/core package. (#​16224)

• telemetrygen: uses the go logging SDK instead of pdata (#​18902)

• elasticsearchexporter: Add explicit bounds histogram support to metrics (#​34045)

• hostmetricsreceiver: allow configuring log pipeline to send host EntityState event (#​33927)

• elasticsearchexporter: Introduce an experimental OTel native mapping mode for logs (#​33290)

• extension/healthcheckv2: Add extension/subcomponent management logic. (#​26661)

• otlpjsonconnector: Add connector's implementations (#​34249, #​34208)

• windowsperfcountersreceiver: Improve handling of non-existing instances for Windows Performance Counters (#​33815)
  It is an expected that when querying Windows Performance Counters the targeted instances may not be present.
  The receiver will no longer require the use of recreate_query to handle non-existing instances.
  As soon as the instances are available, the receiver will start collecting metrics for them.
  There won't be warning log messages when there are no matches for the configured instances.

• kafkareceiver: Add settings session_timeout and heartbeat_interval to Kafka Receiver for group management facilities (#​28630)

• otelarrowreceiver, otelarrowexporter: OTel-Arrow internal packages moved into this repository. (#​33567)
  New integration testing between otelarrowexporter and otelarrowreceiver.

• otlpjsonconnector: Move connector's stability to alpha. (#​34208, #​34253)

• pkg/ottl: Adds an Format function to OTTL that calls fmt.Sprintf (#​33405)

• vcenterreceiver: Adds a number of default disabled vSAN metrics for Clusters. (#​33556)

• vcenterreceiver: Adds a number of default disabled vSAN metrics for Virtual Machines. (#​33556)

🧰 Bug fixes 🧰

• clickhouseexporter: Increase the default number of queue consumers to 10 (#​34176)
• opencensusreceiver: Do not report an error into resource status during receiver shutdown when the listener connection was closed. (#​33865)
• datadogconnector: Produce stats for non-root client and producer spans when connector.datadogconnector.NativeIngest and compute_top_level_by_span_kind are enabled (#​34197)
  You should have only run into this bug when ALL the conditions below are met | 1. feature gate connector.datadogconnector.NativeIngest is enabled | 2. config compute_top_level_by_span_kind is set to true | 3. config compute_stats_by_span_kind is unset or set to false | 4. you have child spans with client or producer span kind
• datadogconnector: Respect _dd.measured when connector.datadogconnector.NativeIngest is enabled (#​34197)
  Spans with attribute _dd.measured set to 1 will always get Datadog APM stats
• deltatocumulativeprocessor: fix bucket counts when downscaling exp histograms with odd offsets (#​33831)
• otelarrowreceiver: Fix potential goroutine leak when in stream-shutdown. (#​34236)
• otelarrowreceiver: Eliminate one spurious span error. (#​34175)
• pkg/ottl: Handle JSON array provided to ParseJSON function (#​33535)
• exporter/datadog: Fixes a bug where otelcol_exporter_sent_log_records was reporting double as many logs sent when using the logs agent feature gate. (#​33887)
• statsdeceiver: Log only non-EOF errors when reading payload received via TCP. (#​33951)
• vcenterreceiver: Adds destroys to the ContainerViews in the client. (#​34254)
  This may not be necessary, but it should be better practice than not.
