🚀 New components 🚀

• stefreceiver: Update stability of STEF receiver to Alpha. (#40062)

💡 Enhancements 💡

• coralogixexporter: Added a mechanism to drop telemetry data when rate limit, quota or authorization errors are encountered. (#40074)
  Added a new configuration option to the Coralogix exporter to enable a rate limiter mechanism.
  The rate limiter mechanism is disabled by default. It can be configured using the following configuration options:

  rate_limiter:
  enabled: true
  threshold: 10
  duration: 1m

  Where:

  • enabled is a boolean flag to enable the rate limiter mechanism.
  • threshold is the number of errors to trigger the rate limiter mechanism (default: 10).
  • duration is the duration of the rate limit window (default: 1 minute).

  Note the number of errors is cumulative and reset after the duration has passed or a successful request is made.

• coralogixexporter: Print metrics causing the partial success response from the backend. (#40199)

• awss3receiver: Add SQS support to the awss3receiver component (#36315)

  Implements Service Attributes.

  If you are using the file log receiver, you can now create the same resource attributes as traces (via OTLP) received
  from an application instrumented with the OpenTelemetry Operator -
  simply by adding the
  extract: { metadata: ["service.namespace", "service.name", "service.version", "service.instance.id"] }
  configuration to the k8sattributesprocessor processor.
  See the documentation for more details.

• signaltometricsconnector: Add support for parsing gauge metrics from any signal types (#37093)

  The new metric is named sqlserver.os.wait.duration and disabled by default.

• receiver/sqlserver: Enable sqlserver.page.life_expectancy metric for all configurations (#39940)
  This metric was originally only available when running on Windows, but is
  now available for all configuration options, including direct connection.
  Since this metric is enabled by default, users who have direct connection
  configured will now have this metric emitted by default.

• sqlserverreceiver: Add configuration option top_query_collection.collection_interval for top query collection to make the collection less frequent. (#40002)

  • This change only applies to the top_query_collection feature.

• postgresqlreceiver: fix too many top query got reported. top query should only report those queries were executed during the query interval (#39942)

• filelogreceiver: Introduce utf8-raw encoding to avoid replacing invalid bytes with \uFFFD when reading UTF-8 input. (#39653)

• internal/splunk: Treat HTTP 403 Forbidden as a permanent error. (#39037)

  • Splunk responses with a 403 typically indicate an authentication or authorization issue that is not likely to be resolved by retrying.
  • This change ensures that the error is treated as permanent to avoid unnecessary retries.
  • This change is applicable to splunkhecexporter, signalfxexporter.

• spanmetricsconnector: Fix bug causing span metrics calls count to be always 0 when using delta temporality (#40139)

• kafkareceiver, kafkaexporter: Add support for named encoding extensions in kafkareceiver and kafkaexporter (#40142)

🛑 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)

• 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

  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.

• elasticsearchexporter: Dynamically route documents by default unless {logs,metrics,traces}_index is non-empty (#38361)
  Overhaul in document routing. Deprecate and make {logs,metrics,traces}_dynamic_index config no-op. Config validation error on {logs,metrics,traces}_dynamic_index::enabled and {logs,metrics,traces}_index set at the same time, as users who rely on dynamic index should not set {logs,metrics,traces}_index. Remove elasticsearch.index.{prefix,suffix} handling. Replace it with elasticsearch.index handling that uses attribute value as index directly. Users rely on the previously supported elasticsearch.index.prefix and elasticsearch.index.suffix should migrate to a transform processor that sets elasticsearch.index. Fix a bug where receiver-based routing overwrites data_stream.dataset.

• elasticsearchexporter: Change default mapping::mode config to otel (#37241)
  The new default, OTel mapping mode, requires Elasticsearch 8.12+. To retain the old behavior, explicitly set mapping::mode to none.

• 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'
    • k8s.namespace.creation_timestamp: The time when the namespace object was created.
  • Adds the following attributes to container entity:
    • container.creation_timestamp: The time when the container was started. Only available if container is either in 'running' or 'terminated' state.

• extension/oauth2clientauth: Add expiry_buffer config to oauth2client extension, allowing token refresh before expiration with a default buffer of 5 minutes. (#35148)

  • 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)

• 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
    }
  }
