🛑 Breaking changes 🛑

• exporter/clickhouse: Remove deprecated clickhouse.json feature gate. Users should set json: true in the exporter config directly. (#​47888)

• extension/aws_logs_encoding: Remove deprecated format values and the vpc_flow_log config field. (#​42901)
  The deprecated format values vpc_flow_log, elb_access_log, s3_access_log, cloudtrail_log,
  waf_log, and cloudwatch_logs_subscription_filter are no longer supported. Use vpcflow,
  elbaccess, s3access, cloudtrail, waf, and cloudwatch respectively. The deprecated
  vpc_flow_log config field has been removed; use vpcflow instead.

• pkg/ottl: Return errors when OTTL datapoint context setters are used on an incompatible data point type (#​48384)
  For example, set(explicit_bounds, [1.0]) against a NumberDataPoint now returns an error
  rather than silently no-opping. Statements that were previously failing silently due to data
  point type mismatches will now surface as errors.

  Affected paths and the data point types they support:

  • value_double, value_int: NumberDataPoint
  • explicit_bounds, bucket_counts: HistogramDataPoint
  • scale, zero_count, positive, positive.offset, positive.bucket_counts,
    negative, negative.offset, negative.bucket_counts: ExponentialHistogramDataPoint
  • quantile_values: SummaryDataPoint
  • exemplars: NumberDataPoint, HistogramDataPoint, ExponentialHistogramDataPoint
  • count, sum: HistogramDataPoint, ExponentialHistogramDataPoint, SummaryDataPoint

• processor/filter: Promote processor.filter.defaultErrorModeIgnore feature gate to beta. (#​47232)
  The default error_mode of the filter processor is now ignore instead of propagate. To restore the previous behavior, disable the feature gate with --feature-gates=-processor.filter.defaultErrorModeIgnore.

• processor/transform: Move the processor.transform.defaultErrorModeIgnore feature gate to beta. The default top-level error_mode is now ignore instead of propagate. (#​48415)
  To revert to the previous default, disable the gate with --feature-gates=-processor.transform.defaultErrorModeIgnore.

• receiver/http_check: Fix timing metrics (httpcheck.dns.lookup.duration, httpcheck.client.connection.duration, httpcheck.tls.handshake.duration, httpcheck.client.request.duration, httpcheck.response.duration) always reporting 0 on fast networks where phase durations are sub-millisecond. Metrics now report values in nanoseconds instead of milliseconds. (#​47257)
  Integer division truncated sub-millisecond durations to 0. Metrics now use nanoseconds as the unit, so a 500µs duration is reported as 500,000 rather than 0.

• receiver/jaeger: Remove stable gate receiver.jaeger.DisableRemoteSampling (#​48616)

• receiver/pprof: Restructure config under remote, file, self, and server sections, and add HTTP push ingestion at POST /v1/pprof. (#​48276)
  The top-level fields endpoint, include, collection_interval, initial_delay,
  block_profile_fraction, and mutex_profile_fraction are now nested under the
  corresponding remote, file, or self subsection. Multiple modes can be enabled
  on a single receiver instance, each with its own collection interval. A new
  server section enables push-mode ingestion of pprof data over HTTP.

🚩 Deprecations 🚩

• connector/metrics_as_logs: Rename component type from metricsaslogs to metrics_as_logs to follow snake_case naming convention. The old name is kept as a deprecated alias. (#​48016)

• exporter/load_balancing: Rename the loadbalancing exporter to load_balancing. The old loadbalancing type remains available as a deprecated alias. (#​45339)

• pkg/kafka/configkafka: Deprecate Kafka client config fields that became no-ops after the migration to franz-go. (#​48260)

  • resolve_canonical_bootstrap_servers_only: franz-go has no direct equivalent
    to the associated Sarama config.
  • auth.sasl.version: franz-go negotiates the SASL handshake version
    automatically.

  Both fields are still accepted in configuration for backwards compatibility,
  but have no effect at runtime. They will be removed in a future release.

• processor/k8s_attributes: Deprecate deployment_name_from_replicaset and default deployment name extraction to the ReplicaSet name heuristic. (#​48447)

• processor/resource_detection: Rename to resource_detection with deprecated alias resourcedetection (#​48525)

🚀 New components 🚀

• processor/gen_ai_normalizer: Add a processor that normalizes GenAI telemetry attributes from OpenInference and OpenLLMetry to the official OTel GenAI Semantic Conventions. (#​46069)

💡 Enhancements 💡

• cmd/opampsupervisor: Adds support for authenticator extensions in the supervisor when connecting to the upstream OpAMP server. (#​47690)
  The Supervisor now supports the Bearer Token Authenticator Extension, Basic Auth Authenticator Extension, and OAuth2 Client Credentials Authenticator Extension. See the readme for more details.

• cmd/opampsupervisor: Adds a framework for the supervisor to utilize extensions from the collector ecosystem (#​47690)

• cmd/opampsupervisor: Initial PR implementing package upgrades. Contains skeleton code that is unused. (#​47298)

• connector/count: Support OTTL path context names in conditions. (#​48316)
  Conditions for spans, span events, metrics, data points, logs, and profiles can now use
  context-prefixed paths (e.g. span.attributes["env"], resource.attributes["host"],
  metric.name). Existing un-prefixed paths continue to work; they are interpreted in
  the context of the enclosing block. It is recommend to update your configuration to the new syntax
  to avoid breaking changes in the future.

• connector/signal_to_metrics: Support OTTL context path prefixes in conditions and value expressions. (#​48357)
  OTTL strings in conditions, value, count, and keys_expression fields may now use context path
  prefixes (e.g. span.attributes["foo"], datapoint.value_int, log.body, profile.duration_unix_nano).
  Unprefixed paths continue to work; it is highly recommend to use the new syntax to avoid breaking changes in the future.

• connector/span_metrics: Add an opt-in series_expiration setting to expire stale spanmetrics series without changing existing metrics_expiration behavior. (#​44187)

• connector/sum: Support OTTL path-context names (e.g. span.attributes["foo"], resource.attributes["bar"], metric.name) in the conditions field. (#​48329)
  Un-prefixed paths continue to work for now. If you are using un-prefixed paths, the updated statements will be printed on startup. It is highly recommended to switch to the new syntax to avoid breaking changes in the future.

• exporter/alertmanager: adds support for sending logs to Alertmanager. (#​48099)

• exporter/elasticsearch: Implement experimental _noindex mapping hint to suppress indexing of individual signals. (#​48310)
  This is an experimental feature and may change or be removed in future releases.
  When a span, span event, log record, or metric data point carries the
  _noindex value in its elasticsearch.mapping.hints attribute, the
  exporter skips emitting the bulk index operation for that document.

• exporter/google_cloud_storage: Add retry and sending queue configuration options (#​48045)
  Introduces retry_on_failure and sending_queue support via exporterhelper. Also ensures that non-retryable GCS SDK errors correctly return permanent errors to halt the sending queue, preventing infinite retries. Includes documentation on the interaction between GCS SDK retries and exporter helper retries.

• exporter/honeycomb_marker: Support OTTL path-context names (e.g. log.body == "x", resource.attributes["service.name"] == "y") in markers[].rules.log_conditions. (#​48325)
  Un-prefixed paths continue to work for now. If you are using un-prefixed paths, the updated statements will be printed on startup. It is highly recommended to switch to the new syntax to avoid breaking changes in the future.

• exporter/kafka: Add health reporting to kafka exporter. (#​47293)

• exporter/kafka: Add per-signal message_key_from_metadata_key to derive the Kafka record key from client metadata. (#​29433)
  Each signal (logs, metrics, traces, profiles) now accepts a message_key_from_metadata_key
  field that names a client metadata key whose value is used as the Kafka record key. This is mutually
  exclusive with the existing partition_* flags for the same signal. If the metadata key is absent
  or empty the record key is left nil.

• exporter/load_balancing: Add owner_account option to AWS Cloud Map resolver for cross-account namespace discovery (#​47895)
  The owner_account field allows the AWS Cloud Map resolver to discover instances
  in namespaces shared from other AWS accounts using AWS RAM. This maps directly to
  the OwnerAccount parameter in the AWS Cloud Map DiscoverInstances API call.

• exporter/sumologic: Modify the sumologic exporter's default batching configuration (#​47820)

• extension/aws_logs_encoding: Add cloudwatch.streams for the cloudwatch format to route subscription-filter events to different inner encoding extensions based on logGroup/logStream patterns. (#​46458)
  Each stream accepts a name, an encoding (component ID of the inner extension), optional
  log_group_pattern / log_stream_pattern matchers, and an optional payload mode (message
  or envelope). Known names (vpcflow, cloudtrail, lambda, waf, rds, eks, apigateway) carry
  default patterns and payload modes reflecting AWS conventions. Routing is per envelope, so
  CloudWatch payloads aggregating multiple log groups (e.g. from Firehose) are dispatched
  correctly. Envelopes that match no stream fall back to the default subscription-filter
  behavior.

• pkg/stanza: Respect the "SynchronousLogEmitter" feature gate in container parser operator. (#​47828)
  The container parser operator now respects the stanza.synchronousLogEmitter feature gate,
  using the synchronous log emitter when enabled to prevent possible data loss. Enabling the
  feature gate disables batching within the container parser.

• processor/cardinality_guardian: Add core processor logic, HLL sharding, enforcement modes, and inline spatial reaggregation to cardinalityguardianprocessor. (#​47368)

• processor/drain: Add snapshot persistence via storage extension to save and restore the Drain tree across restarts. (#​48075)
  New config fields: storage (ID of a storage extension) and save_interval (periodic snapshot interval).
  With shared storage, periodic saves allow new instances in a scaled deployment to inherit a trained tree.

• processor/gen_ai_normalizer: Rename component type from genainormalizer to gen_ai_normalizer. (#​46069)

• processor/gen_ai_normalizer: Add the openllmetry source for normalizing OpenLLMetry (Traceloop) GenAI attributes. (#​46069)

• processor/gen_ai_normalizer: Implement attribute and value normalization for the OpenInference source. (#​46069)

• processor/k8s_attributes: Improve k8s.cronjob.name extraction (#​44831)
  Improve CronJob name extraction to use the Job informer when already running.
  Otherwise use heuristic to match the Job name's and check if the last 8-digits are a valid timestamp
  closely matching the pod creation time (24h window).

• processor/log_dedup: Support OTTL path-context names (e.g. log.attributes["foo"], resource.attributes["bar"]) in the conditions field. (#​48266)
  Un-prefixed paths continue to work for now. If you are using un-prefixed paths, the updated statements will be printed on startup. It is highly recommended to switch to the new syntax to avoid breaking changes in the future.

• processor/schema: Promote schema processor from development to alpha stability and add to contrib distribution (#​47428)

• processor/schema: Add migration mode to preserve original attributes alongside renamed ones during schema version changes (#​47420)

• processor/schema: Add optional storage extension support to persist fetched schema files across collector restarts (#​48222)

• processor/tail_sampling: Support OTTL path-context names (e.g. span.attributes["foo"], resource.attributes["bar"], spanevent.name) in the ottl_condition policy. (#​48330)
  Un-prefixed paths continue to work for now. If you are using un-prefixed paths, the updated statements will be printed on startup. It is highly recommended to switch to the new syntax to avoid breaking changes in the future.

• processor/tail_sampling: Switch the rate_limiting policy to a token bucket and add burst_capacity to allow short bursts of traffic above the sustained spans-per-second rate. (#​48226)
  If burst_capacity is not set, it defaults to 2x spans_per_second, mirroring the bytes_limiting policy.

  Existing configurations will see slightly different behavior: the bucket starts with a default burst of 2x
  spans_per_second tokens. A trace whose span count equals spans_per_second can now be sampled (the previous
  strict < comparison meant spans_per_second: 1 would never sample).
  Set burst_capacity explicitly to match the previous per-second cap if needed.

• provider/s3: Add support for Amazon S3-compatible services (e.g. MinIO) using path-style endpoints and insecure HTTP URIs. (#​47595)

  • Hosts with non-Amazon DNS suffixes are now treated as path-style endpoints (s3://host/bucket/key) instead of virtual-hosted-style.

• receiver/awscloudwatch: Add metrics support to the AWS CloudWatch receiver. (#​47330)

• receiver/file_log: Improves file-reading efficiency by evicting previously read data from the OS page cache. (#​48273)
  Clears the cache on Linux; acts as a no-op on unsupported platforms.

• receiver/host_metrics: Warn and disable process.handles at startup on platforms where it is not supported, instead of logging an error every scrape cycle. (#​47095)
  process.handles is only supported on Windows. Previously, enabling it on other
  platforms would spam "only supported on Windows" errors on every scrape cycle
  for every process. The factory now checks for this at construction, logs a
  single warning, and disables the metric so the hot path is never exercised.

• receiver/host_metrics: Warn and disable process.paging.faults at startup on platforms where it is not supported, instead of logging an error every scrape cycle. (#​47095)
  process.paging.faults is only supported on Linux. Previously, enabling it on other
  platforms would spam "not implemented" errors on every scrape cycle for every process.
  The factory now checks for this at construction, logs a single warning, and disables
  the metric so the hot path is never exercised.

• receiver/host_metrics: Warn and disable process.context_switches at startup on platforms where it is not supported, instead of logging an error every scrape cycle. (#​47095)
  process.context_switches is only supported on Linux. Previously, enabling it on other
  platforms would spam "not implemented" errors on every scrape cycle for every process.
  The factory now checks for this at construction, logs a single warning, and disables
  the metric so the hot path is never exercised.

• receiver/host_metrics: Warn and disable process.signals_pending at startup on platforms where it is not supported, instead of logging an error every scrape cycle. (#​47095)
  process.signals_pending is only supported on Linux (via /proc//limits). Previously,
  enabling it on other platforms would spam "not implemented" errors on every scrape cycle
  for every process. The factory now checks for this at construction, logs a single
  warning, and disables the metric so the hot path is never exercised.

• receiver/http_check: Enables dynamic metric reaggregation in the HTTP Check receiver. This does not break existing configuration files. (#​46358)

• receiver/k8s_objects: Add top-level interval field as a fallback default pull interval for all pull-mode objects. (#​48452)
  When interval is set at the top-level k8s_objects config, it applies to all pull-mode
  objects that do not set their own per-resource interval. The resolution order is:
  per-resource interval → top-level interval → built-in default (1h).
  Watch-mode objects are unaffected. Existing configurations continue to work without change.

• receiver/kubelet_stats: Add optional k8s.container.ephemeral_storage.usage metric to kubeletstats receiver. (#​47601)

• receiver/kubelet_stats: Enables dynamic metric reaggregation capability (#​46363)

• receiver/ntp: Enable scraper reaggregation for the NTP receiver (#​46370)

• receiver/oracledb: Add new attributes to db.server.query_sample event for enhanced session monitoring (#​48216)
  Add 4 new attributes to the db.server.query_sample event:
  oracledb.query.wait_time, oracledb.query.started, oracledb.session.started,
  and oracledb.session.duration. Timestamps are in UTC ISO 8601 format.
  These attributes enable better monitoring of query wait times, execution
  timing, and session lifecycle.

• receiver/oracledb: Adds blocking session and lock attributes to db.server.query_sample events for Oracle blocking session detection. Blocking attributes are always emitted (empty string / 0 when not blocked). (#​48143)
  New attributes under oracledb.blocking.*: oracledb.blocking.blocker.sid, oracledb.blocking.blocker.root_sid,
  oracledb.blocking.blocker.state, oracledb.blocking.start_time, oracledb.blocking.wait_duration,
  oracledb.blocking.lock.type, oracledb.blocking.lock.mode, oracledb.blocking.object.owner, oracledb.blocking.object.name.
  oracledb.blocking.start_time provides an estimated UTC timestamp (RFC3339) of when blocking began.
  Filters to S.TYPE = 'USER' to exclude SYS/background sessions.
  Idle blockers (INACTIVE sessions holding locks) are captured.
  All blocking attributes are always present on every db.server.query_sample event; empty string / 0 values indicate no active blocking.

• receiver/oracledb: Add operational metrics for data dictionary hit ratio, recycle bin size, and storage usage (#​47303)
  Add 4 new opt-in metrics (disabled by default, stability: development):
  oracledb.data_dictionary.hit_ratio, oracledb.recycle_bin.limit,
  oracledb.storage.usage, and oracledb.storage.utilization.

• receiver/prometheus_remote_write: Performance improvements while processing remote write requests. (#​47850)

• receiver/saphana: Enable the re-aggregation feature for the SAP HANA receiver. (#​46378)

• receiver/sqlserver: Add sqlserver.query.last_started and db.namespace attributes to db.server.top_query events. (#​48217)
  The db.server.top_query log records now include:

  • sqlserver.query.last_started: ISO 8601 timestamp of when the query last started executing.
  • db.namespace: the database name, populated via DB_NAME(st.dbid) in the underlying SQL query.

• receiver/vcenter: Add max_query_metrics option to batch QueryPerf requests, preventing vCenter resource exhaustion in large deployments. (#​47941)

• receiver/windows_event_log: Add event_driven_scraping config option (#​48235)
  The new event_driven_scraping config option enables the event-driven scraping model on the
  windows event log input (and the windowseventlog receiver) without requiring the
  stanza.windows.eventDrivenScraping feature gate. Event-driven scraping is enabled when
  either the config option or the feature gate is set. This configuration option should be treated
  as experimental until the feature gate has been promoted from alpha stability.

• receiver/windowsservice: Advancement of windows service receiver from development to alpha (#​48176)

🧰 Bug fixes 🧰

• connector/service_graph: Fix client-side exponential histograms being emitted with a zero timestamp, causing backends like Grafana Cloud Mimir to reject them. (#​48049)
  collectClientLatencyMetrics omitted SetTimestamp on the exponential-histogram data point, so the
  zero-value timestamp leaked through. The server-side function and the client-side explicit-bucket
  branch were already correct.

• exporter/datadog: Honor tls.insecure_skip_verify for logs flowing through datadogexporter (#​48523)

• exporter/datadog: Fix percentile aggregations collapsing to 0 for OTLP explicit-bucket histograms whose first non-empty bucket is (0, B]. (#​48478)
  Affects the default boundary set used by Micrometer's OTLP registry and many
  OTel SDKs ([0, 5, 10, 25, 50, 75, 100, 250, …]). With high-cardinality
  tagging and short delta intervals, per-bucket counts of 1 or 2 made the
  zero-bin leak dominate, collapsing p50…p99 aggregations to 0. avg, sum,
  min, max, and count were not affected.

• extension/sumologic: Make metadata update process async to prevent collector startup failure when metadata endpoint is unavailable (e.g. Windows service starting before network initialization). (#​48450)

• pkg/translator/splunk: Propagate the OTLP log record EventName field into the Splunk HEC event under the configured otel_to_hec_fields/name key (default otel.log.name). (#​48048)

• processor/k8s_attributes: Preserve an upstream-set container.image.tags resource attribute when processor.k8sattributes.EmitV1K8sConventions is enabled, matching the behavior of container.image.tag and container.image.repo_digests. (#​45869)

• processor/k8s_attributes: Re-enable otelcol.k8s.pod.association metric with low-cardinality pod_identifier attribute. The attribute now encodes the association source type/name (e.g. "connection", "resource_attribute/k8s.pod.ip") rather than actual pod identifier values, preventing unbounded metric time series growth. (#​47669)

• processor/schema: Enforces that all prefetched schemas are completed before starting. (#​48258)

• receiver/azure_blob: Delete blobs only upon successful processing (#​48211)
  Blobs that fail to be processed will now remain in the container and will be retried on the next poll. Users with consistently failing pipelines may see container growth or duplicate emissions on retry.

• receiver/azure_monitor: fix(azuremonitorreceiver): prevent duplicate sample timestamps in batch scraper (#​47938)

• receiver/cloudflare: Preserve array-typed Cloudflare log fields as OTLP attributes instead of dropping them. (#​46716)

• receiver/iis: The IIS receiver was failing to start when a disabled metric was not present in the system (#​48609)
  The IIS receiver was attempting to create watchers for all metrics, even those that were disabled.
  This was causing the receiver to fail to start if any of the disabled metrics were not present in the system,
  which is a valid scenario for some of the IIS metrics. Now, the receiver will only attempt to create watchers
  for enabled metrics, so it should start successfully as long as all enabled metrics are present in the system.

• receiver/mysql: Exclude collector's own queries from Query Sample collection to prevent feedback loop. (#​47904)
  Adds a /* otel-collector-ignore */ comment prefix to the Query Sample SQL template and filters
  it out via a NOT LIKE clause on statement.sql_text.

• receiver/oracledb: Exclude the collector's own monitoring queries from Query Sample collection using native session ID filtering. (#​47366)
  Uses native session evaluation (AND S.SID != SYS_CONTEXT('USERENV', 'SID')) to filter the collector's active queries from V$SESSION. This bypasses Go connection pool limitations and avoids the performance overhead of text-matching on VARCHAR2 or CLOB fields.
  Top Query collection is no longer filtered, so collector-originated statements can still appear there for troubleshooting.

• receiver/podman_stats: Fix incorrect network I/O metric recording (#​48313)
  The podman receiver was incorrectly recording network I/O metrics, with the received bytes and transmitted bytes swapped.
  This fix corrects the recording of these metrics to ensure accurate telemetry data is collected.

• receiver/prometheus_remote_write: Fix otelcol_receiver_accepted_metric_points reporting resource count instead of data point count. (#​48306)

• receiver/prometheus_remote_write: Fix broken trace propagation to downstream pipeline components. (#​48548)

• receiver/prometheus_remote_write: Properly handle NaN native histograms, and drop points associated with the native histogram overflow buckets. (#​47728)

• receiver/sqlserver: Exclude collector's own queries from Query Sample collection to prevent feedback loop. (#​47332)
  Adds a /* otel-collector */ comment prefix to the Query Sample SQL template and filters it out
  via a WHERE clause on sys.dm_exec_sql_text. Also excludes the current session via @​@​SPID.
  Top Query collection is intentionally left unfiltered so users can see the monitoring cost.

• receiver/syslog: Support days with leading zeros in RFC 3164 syslogs (#​47665)

• receiver/yang_grpc: Fix setting metric attributes from context bag. (#​48568)

• scraper/zookeeper: Fix zk_avg_latency metric being silently dropped on Zookeeper 3.7+ where the value is reported as a float. (#​47320)

💡 Enhancements 💡

• all: Support building with AIX (#​47010)

• cmd/opampsupervisor: Add support for declarative telemetry.resource configuration while preserving legacy inline resource attributes (#​45116)
  cmd/opampsupervisor now accepts typed telemetry resource configuration,
  including declarative resource attributes and detectors, and validates
  unsupported mixed or deprecated forms.
  Example:
  telemetry:
  resource:
  attributes:
  - name: service.name
  value: opamp-supervisor

• exporter/datadog: Add Kubernetes host alias provider to datadog exporter. (#​47199)
  In Kubernetes environments, the Datadog exporter now automatically adds nodeName-clusterName as a
  host alias in the host metadata payload. Both the node name and cluster name must be discoverable for the alias to
  be added; the cluster name is resolved from cloud provider metadata (Azure, EC2, or GCP).

• exporter/elasticsearch: Add ability to set filter_path in Elasticsearch exporter via the bulk_response_filter_path option. (#​47204)

• exporter/file: Allow usage of append mode with zstd compression (#​44382)

• exporter/kafka: Allow record_headers to accept multiple headers with the same key. (#​48092)

• exporter/loadbalancing: Add stable attribute routing key encoding for traces and metrics in the loadbalancing exporter (#​46094, #​46095)
  Routing keys now encode attributes as name=value| segments, including explicit markers for missing attributes.
  Non-string attribute values are deterministically stringified and used consistently across traces and metrics.

• exporter/opensearch: specify an ingest pipeline to be used before writing documents (#​47227)
  The pipeline option allows to specify an existing ingest pipeline that should process incoming documents.
  If the ingest pipeline does not exist, ingestion will fail.

• extension/aws_logs_encoding: Populate ECS fields from VPC Flow Logs as log record attributes (#​38861)

  When enabled, the observer emits a container endpoint with no port
  information for every running container, alongside any per-port endpoints.
  This allows receiver_creator rules of type == "container" to attach
  receivers to every container regardless of whether it exposes ports.
  Defaults to false for backwards compatibility.

• extension/kafkatopics_observer: Switch to the franz-go client. (#​48169)
  This is another step towards consolidating on franz-go for all Kafka components.
  We have already switched the receiver and exporter, and they are working well.

• extension/mcp: Register available tools with MCP server. (#​48103)

• extension/pebble_tail_storage: Add initial implementation of the Pebble tail storage extension. (#​47916)

• pkg/faro: Emit k6_testRunId in the log body when meta.k6.testRunId is present in the Faro payload. (#​47935)
  Surfaces the k6 test run identifier that the Faro Web SDK already
  forwards from window.k6.testRunId, alongside the existing
  k6_isK6Browser key. The reverse (logs -> Faro) translator extracts
  it back into Meta.K6.TestRunID for round-trip parity.

• pkg/pdatatest: Introduce pmetrictest.ValidateMetrics to strictly validate duplicate datapoint identities. (#​48106)

• processor/attributes: Added support for default values in the attributes processor. (#​45352)
  This enhancement allows users to specify default values for attributes in the attributes processor.
  If the primary value source (e.g., environment variable, attribute, or context value) is not available,
  the default value will be used. This ensures that the pipeline doesn't fail due to missing configuration.

• processor/drain: Add drain processor to k8s distribution. (#​47235)

• processor/k8s_attributes: Improve deployment name extraction heuristic when deployment_name_from_replicaset is enabled (#​44831)
  When deployment_name_from_replicaset is true and the ReplicaSet informer is not used for deployment names only,
  the processor derives k8s.deployment.name using the pod-template-hash label and ReplicaSet naming rules.
  When a ReplicaSet informer is running (for example for k8s.deployment.uid), API-backed metadata takes precedence,
  independent of the deployment_name_from_replicaset setting.

• processor/k8s_attributes: Add watch_sync_period config option to configure informer cache resync period. (#​48111)
  The watch_sync_period config option defaults to 5m to match the previously hardcoded behavior.

• processor/k8s_attributes: Use PartialObjectMetadata for non-Pod informers (#​47389)
  Switch Namespace, Node, Deployment, StatefulSet, DaemonSet, and Job informers
  from full typed objects to PartialObjectMetadata via the metadata client.
  These resources only need labels, annotations, UID, name, and owner references—all available
  in object metadata—so fetching full spec/status is unnecessary overhead.

  Pods continue using full objects since they require spec/status
  fields (pod IP, node name, containers, host network).

• processor/resource: Added support for default values in the resource processor. (#​45352)
  This enhancement allows users to specify default values for attributes in the resource processor.
  If the primary value source (e.g., environment variable, attribute, or context value) is not available,
  the default value will be used. This ensures that the pipeline doesn't fail due to missing configuration.

• processor/schema: Add internal metrics for schema translation skip rate and cache hit/miss (#​47638)
  Five new metrics are emitted via the collector's internal telemetry:

  • otelcol_processor_schema_logs.skipped
  • otelcol_processor_schema_metrics.skipped
  • otelcol_processor_schema_traces.skipped
  • otelcol_processor_schema_cache.hits
  • otelcol_processor_schema_cache.misses

  The skip counters increment when a scope has no schema URL at either the scope
  or resource level, making silent pass-throughs observable. The cache counters
  track effectiveness of the in-memory schema cache in CacheableProvider.

• receiver/awsfirehose: awsfirehose receiver now attempts gzip decompression for Firehose records before decoding. (#​46463)

• receiver/azure_event_hub: Expose the Prefetch option for Azure Event Hub receiver (#​48038)

• receiver/couchdb: Enables dynamic metric reaggregation in the CouchDB receiver. This does not break existing configuration files. (#​46351)

• receiver/googlecloudmonitoring: Allow overriding default endpoint for googlecloudmonitoringreceiver (#​47984)
  Adds an endpoint property which overrides the default monitoring.googleapis.com:443 endpoint.
  This is needed when targeting non-standard universe domains (e.g. S3NS: https://docs.cloud.google.com/sovereign-controls-by-partners/docs/data-boundaries/france-data-boundary-s3ns)

• receiver/k8s_cluster: Enable the re-aggregation feature for the k8s_cluster receiver (#​46361)

• receiver/k8s_events: Simplified RBAC example in README to only include required events resource permission. (#​48192)
  A namespace-scoped Role can also be used when the receiver is configured with specific namespaces.

• receiver/kafka: Add support for custom consumer-group partition-assignment strategies via extensions that implement kgo.GroupBalancer. Set group_rebalance_strategy to the component ID of a registered extension to use a custom balancer. (#​48096)
  The four built-in strategies (range, roundrobin, sticky, cooperative-sticky) continue to work unchanged.
  Any other value for group_rebalance_strategy is now resolved as an extension component ID at runtime.

• receiver/kafka: Cache OTel metric attribute sets in broker hook callbacks to reduce per-read allocations (#​47395)
  OnBrokerRead previously rebuilt attribute sets on every call. The computed
  MeasurementOption is now cached per (nodeID, outcome) key and evicted on
  broker disconnect. Growth is bounded by 2 × number-of-brokers.

• receiver/kubelet_stats: Add optional system container metrics (cpu.time, cpu.usage, memory.working_set) to kubeletstats receiver. (#​3531)

• receiver/memcached: Enables dynamic metric reaggregation in the Memcached receiver. This does not break existing configuration files. (#​46364)

• receiver/mysql: Added 'mysql.query_plan' to query sample records collected (#​47413)

• receiver/mysql: Fix the query hash generation for MySQL queries when the query is not explainable. (#​48059)

• receiver/nsxt: Enables dynamic metric reaggregation in the NSX-T receiver. This does not break existing configuration files. (#​46369)

• receiver/prometheus_remote_write: Add debug logging when dropping histograms with invalid schema values (#​48027)

• receiver/sqlserver: Adds idle blocking sessions to db.server.query_sample by appending sleeping blocker rows (with sqlserver.command=IDLE_BLOCKER) when blocker session IDs are missing from active requests. (#​47120)
  Idle blocker enrichment is best-effort: a targeted secondary idle-session query runs only for missing blocker session IDs, and failures are logged as warnings without failing the scrape.

🧰 Bug fixes 🧰

• connector/service_graph: Fix PR 47971 not add WithDeprecatedTypeAlias option in NewFactory() (#​47971)

• exporter/elasticsearch: Return permanent errors for non-retryable HTTP responses to prevent unnecessary upstream retries. (#​47870)

• exporter/kafka: Fix collector hanging indefinitely on shutdown when the Kafka broker is unreachable (#​48140)
  Re-enables the exporterhelper timeout sender (previously disabled with a zero timeout) so that each send attempt is bounded by the configured timeout (default 5s). The per-attempt context is now passed through to ProduceSync, allowing in-flight sends to unblock when the broker is unreachable. FranzSyncProducer.Close also cancels the kgo client context before calling client.Close, ensuring shutdown completes promptly.

• extension/health_check: Fix deadlock when the collector run context is cancelled while the healthcheck extension is present. (#​47591)

• extension/healthcheckv2: Fix deadlock when the collector run context is cancelled while the healthcheck extension is present. (#​47591)

• extension/opamp: Decorrelate service.instance.id and OpAMP instance_uid (#​46495)
  Previously:

  • the service.instance.id reported in the AgentDescription was based on the OpAMP instance UID
  • the instance UID was typically set based on the service.instance.id from the Collector resource attributes
  • it could be overriden using the instance_uid configuration of the OpAMP extension

  This meant that the reported service.instance.id did not always match the Collector resource attributes,
  which is a problem for correlation, and that server implementations got used to the typical case of
  service.instance.id and instance_uid matching, despite there being no guarantee of this.

  Now:

  • the reported value of service.instance.id always matches the Collector resource attributes
  • the instance UID is either taken from the instance_uid configuration or generated randomly.

  This means that the two values can never be expected to match, unless both configurations are explicitly set to the same value.
  That is what the OpAMP supervisor does, which means its behavior is unaffected.

• extension/sumologic: Fix variable shadowing and formatting issues in tests. (#​46602)

• processor/k8s_attributes: Fix a data race when reading the kube-system namespace from the client cache to populate the k8s.cluster.uid attribute. ([#​47910](https://redirect.github.com/open-telem
