  Currently OTTL provides no way to use any defined Converter within another Editor/Converter.
  Although Converters can be passed as a parameter, they are always executed and the result is what is actually passed as the parameter.
  This allows OTTL to pass Converters themselves as a parameter so they can be executed within the function.

🧰 Bug fixes 🧰

• receiver/sshcheck: Add the SSH endpoint as a resource attribute (#24441)

• awsemfexporter: Enforce time to live on metric data that is stored for the purpose of cumulative to delta conversions within EMF Exporter (#25058)
  This change fixes a bug where the cache used to store metric information for cumulative to delta
  conversions was not enforcing its time to live. This could cause excessive memory growth in certain scenarios which could
  lead to OOM failures for Collector. To properly fix this issue package global metric caches were removed and replaced
  with caches that are unique per emf exporter. A byproduct of this change is that no two emf exporters within an
  Collector will share a caches leading to more accurate cumulative to delta conversions.

• awsemfexporter: Add retain_initial_value_of_delta_metric to translateOTelToGroupedMetric, allowing the initial set of metrics to be published (#24051)

• carbonreceiver: Fix Carbon receiver obsrecv operations memory leak (#24275)
  The carbonreceiver has a memory leak where it will repeatedly open new obsrecv operations but not close them afterwards. Those operations eventually create a burden.

  The fix is to make sure the receiver only creates an operation per interaction over TCP.

• datadogexporter: Populate OTLP resource attributes in Datadog logs. Changes mapping for jvm.loaded_classes from process.runtime.jvm.classes.loaded to process.runtime.jvm.classes.current_loaded. (#24674)

• awsxrayexporter: Fix X-Ray Segment status code and exception translations. (#24381)

• receiver/haproxy: Make sure emitted resource metrics have distinct resources by default (#24921)
  This is done by enabling and renaming the following resource attributes:

  • proxy_name -> haproxy.proxy_name
  • service_name -> haproxy.service_name

• receiver/k8sobjects: Fix bug where duplicate data would be ingested for watch mode if the client connection got reset. (#24806)

• datadogreceiver: Fixed NPE on failed to decode message path (#24562)

• zipkinreceiver: Respects zipkin's serialised status tags to be converted to span status (#14965)

• datadogexporter: Correctly set metrics exporter capabilities to state that it mutates data (#24908)
  This could lead to random panics if using more than one metrics exporter.

🛑 Breaking changes 🛑

• receiver/awsfirehose: Change the type of Config.AccessKey to be configopaque.String (#17273)

• receiver/cloudfoundry: Change the type of Config.UAA.Password to be configopaque.String (#17273)

• exporter/datasetexporter: Remove temporary client side attribute aggregation and corresponding traces.max_wait and traces.aggregate config options which are now redundant. (#20660)
  This pull request removes the following attributes from the DataSet trace events: services,
  span_count, error_count. Those attributes were populated on the client side as part of the client
  side aggregation code. This client side aggregation was meant as a temporary solution until a
  proper solution is implement on the server side. Being a temporary solution meant it had many
  edge cases and would only work under specific and limited circumstances (all spans which belong
  to a trace are part of the same batch received by the plugin).

  Corresponding config options (traces.aggregate and traces.max_wait) which are not redundant and
  unused have also been removed.

• mysqlreceiver: removing mysql.locked_connects metric which is replaced by mysql.connection.errors (#23211)

• pkg/ottl: Allow access to the metrics slice in the metric context (#24446)
  This is only a breaking change for users using OTTL in custom components. For all Contrib components this is an enhancement.

• pkg/stanza: Make fileconsumer.PositionalScanner internal (#23999)

• pkg/stanza: Make fileconsumer.Fingerprint internal (#23998)

• receiver/httpcheck: Fail fast on endpoint missing scheme (#23020)
  Previously, when configured with an endpoint without HTTP/HTTPS scheme like "opentelemetry.io",
  the receiver would start correctly, but fail to check the endpoint, producing the httpcheck.error
  metric on every collection interval. After this change, the receiver fails to start, writing
  an error log saying that you need to provide a scheme in the endpoint.

• receiver/jmx: Change the types of Config.{Password,KeystorePassword,TruststorePassword} to be configopaque.String (#17273)

• httpcheckreceiver: support scraping multiple targets (#18823)

  To re-enable host.id on the system detector set system::resource_attributes::host.id::enabled to true:

  resourcedetection:
    detectors: [system]
    system:
      resource_attributes:
        host.id:
          enabled: true

• prometheusreciever: Remove unused buffer_period and buffer_count configuration options (#24258)

• prometheusreceiver: Add the trim_metric_suffixes configuration option to allow enable metric suffix trimming. (#21743, #8950)
  When enabled, suffixes for unit and type are trimmed from metric names.
  If you previously enabled the pkg.translator.prometheus.NormalizeName
  feature gate, you will need to enable this option to have suffixes trimmed.

  Now there is documentation of which metrics are available depending cgroups version being used on the host.

🚩 Deprecations 🚩

• mysqlreceiver: set mysql.locked_connects as optional in order to remove it in next release (#14138, #23274)

💡 Enhancements 💡

• hostmetricsreceiver: Add new Windows-exclusive process.handles metric. (#21379)

• websocketprocessor: Rename websocketprocessor to remoteobserverprocessor (#23856)

• resourcedetectionprocessor: Adds a way to configure the list of added resource attributes by the processor (#21482)
  Users can now configure what resource attributes are gathered by specific detectors.
  Example configuration:

  resourcedetection:
    detectors: [system, ec2]
    system:
      resource_attributes:
        host.name:
          enabled: true
        host.id:
          enabled: false
    ec2:
      resource_attributes:
        host.name:
          enabled: false
        host.id:
          enabled: true
  

  For example, this config makes host.name being set by system detector, and host.id by ec2 detector.
  Moreover:

  • Existing behavior remains unaffected as all attributes are currently enabled by default.
  • The default attributes 'enabled' values are defined in metadata.yaml.
  • Future releases will introduce changes to resource_attributes enabled values.
  • Users can tailor resource detection process to their needs and environment.

• spanmetricsconnector: Added disabling options for histogram metrics and option to exclude default labels from all metrics. In some cases users want to optionally disable part of metrics because they generate too much data or are not needed. (#16344)

• statsdreceiver: All receivers are setting receiver name and version when sending data. This change introduces the same behaviour to the statsd receiver. (#23563)

• zookeeperreceiver: Adds an additional health check metric based off of the response from the zookeeper ruok 4lw command. (#21481)

• k8sclusterreceiver: Switch k8s.pod and k8s.container metrics to use pdata. (#23441)

🧰 Bug fixes 🧰

🛑 Breaking changes 🛑

• redisreceiver: Updates metric unit from no unit to Bytes. (#23454)
  Affected metrics can be found below.

  • redis.clients.max_input_buffer
  • redis.clients.max_output_buffer
  • redis.replication.backlog_first_byte_offset

• nginxreceiver: Bump 'receiver.nginx.emitConnectionsCurrentAsSum' featuregate to beta (enabled by default) (#4326)

• servicegraphprocessor: Change metric names to match the spec (#18743, #16578)
  Latency metric traces_service_graph_request_duration_seconds are deprecated in favor of server and client metrics | traces_service_graph_server_request_seconds and traces_service_graph_client_request_seconds | respectively. Use the feature gate processor.servicegraph.legacyLatencyMetricNames to enable the old metric names.

• prometheusreceiver, prometheusexporter, prometheusremotewrite: Disable pkg.translator.prometheus.NormalizeName feature gate by default (#23208)
  The feature gate pkg.translator.prometheus.NormalizeName was enabled prematurely while translation
  on the prometheus receiver was incomplete. To address this, the feature gate has been reverted back to alpha status.
  This will remain the case until the translation on the receiver side aligns with the translation on the exporter side,
  or until it is replaced with a configuration option or completely removed. To maintain the current behavior, you can
  enable the feature gate using the --feature-gates=pkg.translator.prometheus.NormalizeName command argument.
  However, please note that the translation in the prometheus receiver is a subject to future changes.

• 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 💡

• 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)
