End User Changelog

🛑 Breaking changes 🛑

  • awscloudwatchreceiver: Adds option to set storage for AWS CloudWatch receiver (#32231)

    • The default value of the start_from field in the logs config changed to Unix epoch (1970-01-01T00:00:00Z) when not explicitly configured. This may alter the behavior of existing configurations relying on the previous default.
    • To maintain previous behavior, explicitly configure start_from in the logs configuraiton.

  • k8sobjectsreceiver: Check for K8s API objects existence on receiver startup and not during config validation. (#38803)

  • receiver/kubeletstats: Move receiver.kubeletstats.enableCPUUsageMetrics feature gate to beta (#39487)
    Deprecated metrics container.cpu.utilization, k8s.pod.cpu.utilization and k8s.node.cpu.utilization are being replaced
    by container.cpu.usage, k8s.pod.cpu.usage and k8s.node.cpu.usage.
    To be able to use the deprecated metrics, switch receiver.kubeletstats.enableCPUUsageMetrics feature gate to false.

  • processor/k8sattributes: Change processor/k8sattributes to return error if unset envvar is used for node_from_env_var (#39447)
    Before this was a valid configuration, but had an unexpected behavior to monitor the entire cluster. | To keep the same behavior simply do not set the node_from_env_var value or use empty string.

  • sqlserverreceiver: host.name, sqlserver.computer.name, and sqlserver.instance.name are now resource attributes instead of log attributes. We used to report computer_name and instance_name in the log attributes for top query collection and they are now deprecated. Now we report the three resources attributes in both top query collection and sample query collection. (#39449)
    This change is only relevant for logs.

🚩 Deprecations 🚩

  • spanmetricsconnector: Deprecate the unused configuration dimensions_cache_size (#39646)
    Deprecated configuration dimensions_cache_size, please use aggregation_cardinality_limit instead

🚀 New components 🚀

  • dnslookupprocessor: Add structure of new processor (#34398)
  • datadogextension: Introduce framework for Datadog Extension (#39589)
  • sematextexporter: basic logs implementation (#36465)

💡 Enhancements 💡

  • spanmetricsconnector: Add new aggregation_cardinality_limit configuration option to limit the number of unique combinations of dimensions that will be tracked for metrics aggregation. (#38990)

  • awslogsencodingextension: Add support for S3 Access Logs. (#39161)

  • pkg: Improve performance of azure logs translator. (#39340)

  • azureauthextension: Update stability to alpha. (#39574)

  • countconnector: Add profiles support (#39577)

  • awscloudwatchlogsexporter: Add dynamic log_group_name and log_group_stream naming, based on awsemfexporter (#31382)

  • elasticsearchexporter: Add support for include_source_on_error, which configures whether bulk index responses should include source document on error (#39211)

  • elasticsearchexporter: Introduce LRU cache for profiles (#38606)

  • elasticsearchexporter: Add support for extracting mapping mode from a scope attribute. (#39110)

  • opampextension: Introduces a new config field include_resource_attributes which allows the extension to copy the agent's resource attributes to the non-identifying attributes in the agent description. (#37487)

  • statsdreceiver: Add new config to customize socket permissions when transport is set to unixgram. (#37807)

  • kubeletstatsreceiver: Adds support for collecting Node and Pod network IO/error metrics for all network interfaces (#30196)

  • awss3exporter: add configuration field resource_attrs_to_s3/s3_prefix to support mapping s3 bucket prefix to OTel resource attributes (#37858)
    If resource_attrs_to_s3/s3_prefix is configured, s3 prefix will be determined based on the specified resource attribute and s3uploader/s3_prefix will serve as a fallback.

  • azureblobexporter: Add SerialNumBeforeExtension option to BlobNameFormat in Azure Blob exporter as an option to avoid breaking file extension (#39593)

  • splunkhecexporter: Use ObservedTimestamp if Timestamp is empty. (#39221)

  • githubreceiver: add dedicated job queue spans with cicd.pipeline.run.queue.duration attribute (#39081)

  • hostmetricsreceiver: Possible to enable the process scraper under FreeBSD in the hostmetrics receiver. (#39622)

  • k8sclusterreceiver: add support for k8s leader election in k8s cluster receiver (#38429)
    Allows multiple instances of the k8s cluster receiver to run in a HA mode in a single cluster.

  • kafkareceiver: Add support for configuring Kafka consumer rebalance strategy and group instance ID (#39513)
    This enhancement introduces two optional settings: group_rebalance_strategy and group_instance_id.
    These allow users to override the default Range-based rebalance strategy and optionally provide a static instance ID (as per KIP-345) for cooperative sticky balancing.
    This is particularly useful when handling high-cardinality metric workloads, as it reduces rebalance impact, improves cache reuse, and boosts CPU efficiency.
    Both settings are optional to maintain full backward compatibility.

  • kafkareceiver: Added a new 'topic' attribute to all existing internal consume-claim metrics. (#35336)

  • kafkareceiver: Add max_fetch_wait config setting (#39360)
    This setting allows you to specify the maximum time that the broker will wait for
    min_fetch_size bytes of data to be available before sending a response to the client.
    Defaults to 250ms.

  • receiver_creator: Fix kafkametrics receiver instantiation (#39313)

  • signaltometricsconnector: Add profiles support (#39609)

  • sqlserverreceiver: Accept context_info with traceparent format in query sample collection, setting log record with correct traceId and spanId. (#39539)

  • opampsupervisor: Add support for the opampsupervisor to be able to start with only local config (#38794)

  • prometheusremotewritereceiver: Cache target_info metrics so it can be used to populate metrics' Resource Attributes. (#37277)
    You can read more about resource attributes handling in https://opentelemetry.io/docs/specs/otel/compatibility/prometheus_and_openmetrics/#resource-attributes-1

🧰 Bug fixes 🧰
