🛑 Breaking changes 🛑

• elasticsearchexporter: Remove deprecated fields [min|max]_size_items from batch config (#38836)

• receiver/azuremonitorreceiver: multi subscriptions support and automatic discovery (#36612)

• kafkaexporter: change default client_id to "otel-collector" (#38411)
  The exporter now uses the "configkafka" package which consolidates
  common configuration structures and default values. As a result of
  this change, we update the default client_id value to "otel-collector".

• kafkametricsreceiver: change default client_id to "otel-collector", deprecate "refresh_frequency" (#38411)
  The receiver now uses the "configkafka" package which consolidates
  common configuration structures and default values. As a result of
  this change, we update the default client_id value to "otel-collector",
  and deprecate "refresh_frequency" in favour of "metadata.refresh_interval".

💡 Enhancements 💡

• spanmetricsconnector: Add instrumentation scope to span metrics connector. (#23662)
  This change adds the instrumentation scope to the span metrics connector, which allows users to specify the instrumentation scope for the connector.
  Now, the connector has a new configuration option:

  • include_instrumentation_scope: A list of instrumentation scope names to include from the traces.

  The instrumentation scope name is the name of the instrumentation library that collected the span.

• azuremonitorexporter: support span links for traces for azure monitor exporter (#35855)

• splunkhecreceiver: Splunk HEC timestamp accepts nanoseconds, microseconds, milliseconds, and seconds epoch. (#36571)

• farotranslator: Add Faro translator package (#19180, #35319)

• lokiexporter: Add lokiexporter component to the contrib distribution (#38993)

• oracledbreceiver: Add support for additional read/write metrics (#37814)
  The following metrics are now available, all disabled by default:
  'physical reads direct', 'physical writes', 'physical writes direct',
  'physical read io requests' and 'physical write io requests' metrics'

• tlscheckreceiver: add tlscheck.x509.san attribute (#38872)
  Subject Alternative Name records are stored as an array on the metric.

• prometheusremotewriteexporter: Adds logic to convert from the internal OTEL Metrics unit format to Prometheus unit format and emit unit as part of Prometheus metadata. (#29452)

• awslogsencodingextension: Add support for cloudwatch logs coming from subscription filters. (#38820)

• awscloudwatchencodingextension: Increase component stability to Alpha (#37870)

• awss3exporter: Implement timeout for S3 exporter (#36264)

• azureauthextension: Implement extensionauth.Server and azcore.TokenCredential. (#39012)

• bearertokenauthextension: Allow the header name to be customized in the bearerauthtoken extension (#38793)

• schemaprocessor: Add functionality to transform metrics for the schema processor.
  (#38628)
  Adds functionality to transform metrics using the target schema version.

• elasticsearchexporter: Enable native frame symbolization for Universal Profiling via the symbolization queue indices. (#38577)

• hostmetricsreceiver: Reduced the cost of retrieving number of threads and parent process ID on Windows. Disable the featuregate hostmetrics.process.onWindowsUseNewGetProcesses to fallback to the previous implementation.
  (#32947, #38589)

• prometheusremotewritereciever: Add help ref attribute to metric (#37277)

• hostmetricsreceiver: Reduced the CPU cost of collecting the process.handles metric on Windows. (#38886)
  Instead of using WMI to retrieve the number of opened handles by each process
  the scraper now uses the GetProcessHandleCount Win32 API which results in
  reduced CPU usage when the metric process.handles is enabled.

• pkg/ottl: Enhance the Decode OTTL function to support all flavors of Base64 (#38854)

• rabbitmqreceiver: Enhance the RabbitMQ receiver to collect and report additional node-level metrics: rabbitmq.node.disk_free, rabbitmq.node.disk_free_limit, rabbitmq.node.disk_free_alarm, rabbitmq.node.disk_free_details.rate, rabbitmq.node.mem_used, rabbitmq.node.mem_limit, rabbitmq.node.mem_alarm, rabbitmq.node.mem_used_details.rate, rabbitmq.node.fd_used, rabbitmq.node.fd_total, rabbitmq.node.fd_used_details.rate, rabbitmq.node.sockets_used, rabbitmq.node.sockets_total, rabbitmq.node.sockets_used_details.rate, rabbitmq.node.proc_used, rabbitmq.node.proc_total, rabbitmq.node.proc_used_details.rate. These provide additional observability into the state and resource usage of RabbitMQ nodes. (#38976)

• rabbitmqreceiver: Enhance the RabbitMQ receiver to collect and report additional node-level metrics across multiple categories. These include metrics related to memory, file descriptors, sockets, processes, disk, uptime, scheduling, garbage collection (GC), I/O, message store, connections, clustering, configuration, application info, and context switches. This significantly improves visibility into the performance, state, and resource usage of RabbitMQ nodes. (#38997)

• resourcedetection: Adding the os.version resource attribute to system resourcedetection processor (#38087)

• prometheusremotewritereciever: Separate timeseries with the same labels are now translated into the same OTLP metric. (#37791)
  timeseries that belongs to the same metric should be added to the same datapoints slice.

• prometheusremotewritereceiver: Use Created Timestamps to populate Datapoint's StartTimeUnixNano (#37277)

• workflow: Remove path parts from component label suffixes (#38527)

• sqlserverreceiver: support sqlserverreceiver to record every executing query (#36462)
  We introduced Query Sample collection in this PR. The scraper will record all the currently
  executing queries once (in most case) and report related metrics. With this, user will be
  able to see what queries got executed and can combine with the Top Query to get more insights
  on troubleshooting and fine tuning.

• sqlserverreceiver: Support query-level log collection (#36462)
  Added top query (most CPU time consumed) collection. The query will gather the queries took most of the time during the last
  query interval and report related metrics. The number of queries can be configured. This will enable user to have better
  understanding on what is going on with the database. This enhancement empowers users to not only monitor but also actively
  manage and optimize their MSSQL database performance based on real usage patterns.

• opampsupervisor: Allow controlling Collectors that don't include the nopreceiver and nopexporer (#38809)
  This requires Collectors built with Collector API v0.122.0+. The nopreceiver
  and nopexporter will continue to be supported for a few releases, after which
  only v0.122.0+ will be supported.

• opampsupervisor: Report the reception of an unexpected UID during bootstrapping (#29864)

🧰 Bug fixes 🧰

• metricstarttimeprocessor: Add reset detection for histograms (#38582)

• prometheusremotewriteexporter: Disallow users from setting compression type other than snappy (#37232)
  This change ensures that only the snappy compression type can be set, as required by the Prometheus Remote Write protocol.

• awsecscontainermetrics: Ensure that the storage.read_bytes and storage.write_bytes metrics include i/o counts from all devices (#38301)

• receiver/sqlserver: the current metric scraper would report error when parsing value, the value was parsed as int but actually it should be a float (#38823)

• redisstorageextension: fix missing redis prefix in Batch method (#38877)

• receiver/sqlserver: Ensure all enabled metrics are emitted (#38839)

• kafkareceiver: make calls to error backoff thread-safe and add logging (#38941)

• awsfirehosereceiver: Fixes unmarshal error when request is larger than the buffer limit of bufio.Scanner (#38736)

• axw:prometheusremotewritereceiver-fix-tests: wait for listening port to be closed before shutting down receiver (#38705)

• receiver/sqlserver: Remove warning that server.address and server.port resource attributes will be enabled (#38831)
  There is no intention of enabling these resource attributes by default,
  this change is to simply remove the warning.
  The server.address and server.port resource attributes were, and still are,
  disabled by default.

• awscloudwatchmetricstreamsencodingextension: Return errors when extracting the metrics from the record instead of logging them. (#38596)

• tcpcheckreceiver: Fixed typo in "Metric configuration". (#38889)

• pkg/stanza: Add retries when calls to retrieve Windows event via EvtNext fail with error RPC_S_INVALID_BOUND (1734). (#38149)
  Whenever large events were read in by the Windows event log receiver, via the stanza input operator,
  the collector would fail with error RPC_S_INVALID_BOUND (1734). Now the operator tries to workaround
  this issue by reducing the number of events read on each attempt.
