End user changelog

🛑 Breaking changes 🛑

• telemetrygen: Update attribute of generated traces from net.peer.ip to net.sock.peer.addr to bring it in line with new semconv. (#38043)

• awss3exporter: Replaced the s3_partition option with s3_partition_format to provide more flexibility to users. (#37915, #37503)
  Users can provide custom file partitions using strftime formatting.
  The default value of year=%Y/month=%m/day=%d/hour=%H/minute=%M matches the older pattern (with s3_partition: minute)

  If users do not provide a value for s3_prefix, the exporter will not create a / folder in the bucket.

• elasticsearchexporter: drop support for metrics for none, raw, and bodymap mapping modes (#37928)
  Metrics support is in development, and was added for "ecs" and "otel" mapping modes.
  Support was unintentionally added for the other mapping modes, defaulting to the same
  behaviour as "ecs" mode. While metrics support is still in development, drop support
  from these mapping modes and require users to use the intended mapping modes.

💡 Enhancements 💡

• elasticsearchexporter: Syncs support for compression level on elasticsearch exporter with confighttp. The default compression level is 1 if not set. (#37260)

• processor/transformprocessor: Add support for global conditions and error mode overrides. (#29017)
  Global conditions are now available for context-inferred structured configurations, allowing the use of fully
  qualified paths. Additionally, a new configuration key called error_mode has been added to the context statements group.
  This key determines how the processor reacts to errors that occur while processing that specific group of statements.
  When provided, it overrides the top-level error mode, offering more granular control over error handling.

• pkg/stanza: Allow users to configure initial buffer size (#37786)

• vcenterreceiver: Adds three more vCenter virtual machine performance metrics (#37488)

• k8sclusterreceiver: Adds new descriptive attributes/metadata to the k8s.namespace and the container entity emitted from k8sclusterreceiver. (#37580)

  • Adds the following attributes to k8s.namespace entity:
    • k8s.namespace.phase: The phase of a namespace indicates where the namespace is in its lifecycle. E.g. 'active', 'terminating'

  • Prevents authentication failures by refreshing the token early.
  • The default expiry buffer is set to 5 minutes, and users can adjust it as needed.

• datadogexporter: Add a gauge metric datadog.otel.gateway which is 1 if the collector is used as a gateway or 0 otherwise. (#37499)

• pkg/ottl: Introduce ToCamelCase converter function (#32942)

• googlecloudpubsubreceiver: Turn noisy warn log about Pub/Sub servers into debug, and turn the reset count into a metric (#37571)
  The receiver uses the Google Cloud Pub/Sub StreamingPull API and keeps a open connection. The Pub/Sub servers
  recurrently close the connection after a time period to avoid a long-running sticky connection. Before the
  receiver logged warn log lines everytime this happened. These log lines are moved to debug so that fleets with
  lots of collectors with the receiver don't span logs at warn level. To keep track of the resets, whenever a
  connection reset happens a otelcol_receiver_googlecloudpubsub_stream_restarts metric is increased by one.

• processor/redaction: Introduce 'allowed_values' parameter for allowed values of attributes (#35840)

• exporter/logzioexporter: Remove dependency on Jaeger pkg/cache (#37833)

• routingconnector: Avoid unnecessary copy of the data in routing connector (#37946)

  (#35180)

• tailsamplingprocessor: makes the numeric_attribute more flexible and allows to set only min_value or max_value, without the need to set both (#37328)
  This is useful to have simple configurations like these:

  {
    type: numeric_attribute,
    numeric_attribute: {
      key: http.status_code,
      min_value: 400
    }
  }
  

• testbed: Include the specified resource limits for CPU and memory in the benchmark results (#36720)

🚀 New components 🚀

• envoyalsreceiver: Add a new receiver for the Envoy ALS (Access Log Service). (#36464)
• metricstarttimeprocessor: Add the initial skeleton for the metricsstarttimeprocessor (#37186)
  The component is still in development and is not ready for use.
• exporter/sematext: Add a new component for exporting metrics and logs to Sematext (#36465)

💡 Enhancements 💡

• awss3exporter: Add support for S3 Storgeclass (#35173)

• processor/transformprocessor: Add support for flat configuration style. (#29017)
  The flat configuration style allows users to configure statements by providing a list of statements instead of a
  structured configuration map. The statement's context is expressed by adding the context's name prefix to path names,
  which are used to infer and to select the appropriate context for the statement.

• httpcheckreceiver: Added support for specifying multiple endpoints in the httpcheckreceiver using the endpoints field. Users can now monitor multiple URLs with a single configuration block, improving flexibility and reducing redundancy. (#37121)

• signaltometricsconnector: Move signal to metrics connector to alpha stability (#35930)

• exporter/clickhouse: Adding missing examples of DDL created by the clickhouse exporter (#35903)

• opampsupervisor: add support for headers configuration for reporting own telemetry (#37353)

• opampsupervisor: report own metrics via OTLP instead of prometheus receiver (#37346)

• resourcedetectionprocessor: Expose additional configuration parameters for the AWS metadata client used by the EC2 detector (#35936)
  In some cases, you might need to change the behavior of the AWS metadata client from the standard retryer

  By default, the client retries 3 times with a max backoff delay of 20s.

  We offer a limited set of options to override those defaults specifically, such that you can set the client to retry 10 times, for up to 5 minutes, for example:

  processors:
    resourcedetection/ec2:
      detectors: ["ec2"]
      ec2:
        max_attempts: 10
        max_backoff: 5m

• cumulativetodeltaprocessor: Add metric type filter for cumulativetodelta processor (#33673)

• datadogconnector: Support obfuscating sql queries in APM stats (#37457)
  Ensure that feature flags "enable_receive_resource_spans_v2" and "enable_operation_and_resource_name_logic_v2"
  are also enabled on both Datadog Exporter and Datadog Connector so that span attributes are properly
  mapped to span type and span resource in Datadog APM; otherwise spans and apm stats may not be
  obfuscated and attributes on stats payloads may not match traces.
  See https://docs.datadoghq.com/opentelemetry/schema_semantics/semantic_mapping/?tab=datadogexporter#mapping-opentelemetry-database-system-type-to-datadog-span-type

  NOTE: Long/complex SQL queries may cause a performance impact on APM Stats calculation in Datadog Connector.
  Consider implementing sampling in your pipeline prior to sending traces to Datadog Connector if you experience this.

• resourcedetectionprocessor: Add fail_on_missing_metadata option on EC2 detector (#35936)
  If the EC2 metadata endpoint is unavailable, the EC2 detector by default ignores the error.
  By setting fail_on_missing_metadata to true on the detector, the user will now trigger an error explicitly,
  which will stop the collector from starting.

• elasticsearchexporter: Group data points into a single document even if they are from different but equal resources (#37509)
  This may prevent document rejections in case the same batch contains different resources or scopes that have the same set of attributes

• elasticsearchexporter: Add config logs_dynamic_id to dynamically set the document ID of log records using log record attribute elasticsearch.document_id (#36882)

• elasticsearchexporter: Declare MutatesData: false (#37234)
  When multiple exporters are used, the collector doesn't need to clone the incoming data anymore

• resourcedetectionprocessor: The gcp resource detector will now detect resource attributes identifying a GCE instance's managed instance group. (#36142)

• jaegerreceiver: Log the endpoints of different servers started by jaegerreceiver (#36961)
  This change logs the endpoints of different servers started by jaegerreceiver. It simplifies debugging by ensuring log messages match configuration settings.

• githubgen: Switch over all usages of githubgen to the new tool location, since the old tool was deprecated (#37412, #37294)

• hostmetrics/process: Added support for tracking process.uptime (#36667)

• netflowreceiver: Adds the implementation of the netflow receiver (#32732)
  The receiver now supports receiving NetFlow v5, NetFow v9, IPFIX, and sFlow v5 logs.

• googlecloudpubsubreceiver: Added support for encoding extensions. (#37109)

• processor/transformprocessor: Replace parser collection implementations with ottl.ParserCollection and add initial support for expressing statement's context via path names. (#29017)

• prometheusreceiver: Add receiver.prometheusreceiver.UseCollectorStartTimeFallback featuregate for the start time metric adjuster to use the collector start time as an approximation of process start time as a fallback. (#36364)

• tailsamplingprocessor: Reworked the consume traces, sampling decision, and policy loading paths to improve performance and readability (#37560)

🧰 Bug fixes 🧰

• deltatocumulativeprocessor: In order to cap number of histogram buckets take the min of desired scale across negative and positive buckets instead of the max (#37416)

• filelogreceiver: Fix issue where flushed tokens could be truncated. (#35042)

• connector/routing: Fix config validation with context other than resource (#37410)

• k8sattributesprocessor: Wait for the other informers to complete their initial sync before starting the pod informers (#37056)

• metricsgenerationprocessor: Generated metric name may not match metric being scaled (#37474)

• otlpjsonfilereceiver: Include file attributes and append it to the log record (#36641)

• routingconnector: The connector splits the original payload so that it may be emitted in parts to each route. (#37390)

• pkg/stanza: Fix default source identifier in recombine operator (#37210)
  Its defualt value is now aligned with the semantic conventions: attributes["log.file.path"]

• tailsamplingprocessor: Fixed sampling decision metrics otelcol_processor_tail_sampling_sampling_trace_dropped_too_early and otelcol_processor_tail_sampling_sampling_policy_evaluation_error_total, these were sometimes overcounted. (#37212)
  As a result of this change non-zero values of otelcol_processor_tail_sampling_sampling_trace_dropped_too_early
  and otelcol_processor_tail_sampling_sampling_policy_evaluation_error_total metrics will be lower.
  Before this fix, errors got counted several times depending on the amount of traces being processed
  that tick and where in the batch the error happened.
  Zero values are unaffected.

• signalfxexporter: Warn on dropping metric data points when they have more than allowed dimension count (#37484)
  The SignalFx exporter drops metric data points if they have more than 36 dimensions.
  Currently, the exporter logs at debug level when this occurs.
  With this change, the exporter will log at the warning level.
