End User Changelog

🛑 Breaking changes 🛑

• all: Removes the Google SecOps exporter, as it is no longer being donated. (#46148) Removes the incomplete and non-functional Google SecOps exporter. It should not have been configured by users, so no real world breakage is expected.

• connector/span_metrics: Validate calls_dimensions and histogram.dimensions at startup (#48097) Duplicate dimension names in calls_dimensions or histogram.dimensions previously passed silently; they now fail validation at startup, matching the behaviour of the top-level dimensions setting.

• exporter/prometheus: Promote the exporter.prometheusexporter.DisableAddMetricSuffixes feature gate to beta. (#48930) The deprecated add_metric_suffixes setting is now ignored by default. To preserve the previous no-suffix behavior, set translation_strategy: UnderscoreEscapingWithoutSuffixes.

• receiver/vcenter: Set resourcePoolMemoryUsageAttribute feature gate to beta. (#47552)

🚩 Deprecations 🚩

• exporter/prometheus_remote_write: Rename to prometheus_remote_write with deprecated alias prometheusremotewrite (#45339)

• exporter/signalfx: Traces have been deprecated for the exporter (#48748) Trace correlation functionality no longer requires the signalfx exporter to be included in trace pipelines. Sending traces may now be sent solely via OTLP to enable trace correlation. All trace functionality and configuration will be removed from this exporter in December 2026.

• processor/resource_detection: The k8snode detector is deprecated; use k8s_api instead. (#48597) Both names work and produce identical output. When switching to k8s_api, also rename your config section from k8snode: to k8s_api:; keeping the old key under the new detector name will silently apply defaults instead.

• receiver/apache_spark: Rename apachespark receiver to apache_spark with deprecated alias apachespark (#45339)

• receiver/envoy_als: Rename envoyals receiver to envoy_als with deprecated alias envoyals (#45339)

• receiver/kafka: Deprecate group_rebalance_strategy in favor of group_rebalance_strategies (#48658) Use group_rebalance_strategies to configure one or more ordered protocols. The singular field remains supported for backward compatibility but logs a deprecation warning on startup. group_rebalance_strategy and group_rebalance_strategies are mutually exclusive; setting both fails validation.

• receiver/otlp_json_file: rename to otlp_json_file with deprecated alias otlpjsonfile (#45339)

• receiver/webhook_event: Rename webhookevent receiver to webhook_event with deprecated alias webhookevent (#45339)

• receiver/windows_service: Rename receiver type from windowsservice to windows_service (#45339)

🚀 New components 🚀

• processor/awsecsattributes: Add the initial skeleton for the AWS ECS attributes processor, which will enrich telemetry with AWS ECS metadata. (#44476)

💡 Enhancements 💡

• cmd/opampsupervisor: Allow starting the Collector with a startup fallback config until successfully connected to the OpAMP backend (#44368) When there's no previous configuration state persisted in disk, the Supervisor now starts with a startup fallback configuration until it can successfully connect to the OpAMP backend. At this moment the regular configuration (indicated by agent::config_files) is restored. If a previous configuration state is persisted, it will be used to start the Collector.

• cmd/schemagen: Add -r flag to resolve external $ref entries inline, replacing references with the actual type definitions from the referenced packages. (#48735) When -r is passed, schemagen recursively resolves cross-package $refs and inlines the referenced type definitions. References that cannot be resolved are dropped with a warning.

• cmd/schemagen: Add factoryMaps override to generate schemas for config fields populated via factory dispatch maps. (#48815) Some components tag a config field mapstructure:"-" and populate it at runtime by dispatching against a package-level factory map (e.g. hostmetricsreceiver's scrapers field). The schemagen parser previously skipped these fields entirely.

  A new factoryMaps option in .schemagen.yaml componentOverrides instructs schemagen to AST-walk the named factory var, enumerate all registered entries, and synthesize a typed object property whose keys are the discriminator strings. Three factory var shapes are supported: call expressions (key resolved from internal/metadata), composite literals with inline component.MustNewType("key") keys, and composite literals with qualified pkg.ConstName keys.

  Wired up for receiver/hostmetricsreceiver (11 scraper keys), receiver/ciscoosreceiver (2 scraper keys), and processor/geoipprocessor (1 provider key).

• connector/span_metrics: Support for glob expressions in the dimensions field of the spanmetrics connector config (#48097) It is now possible to specify attributes to add as dimensions to metrics using glob expressions, in addition to exact string matching

• exporter/azuremonitor: Add tag_mappings config to override the resource-attribute precedence used to populate Application Insights envelope tags (#47657) The optional tag_mappings: block accepts an ordered list of sources per tag. Sources containing a . are treated as resource attribute keys; sources without a . are treated as string-literal terminal defaults. The first non-empty value wins.

  Supported keys: cloud_role_instance (default [service.instance.id]) and application_version (default [service.version]). Defaults preserve the historical hardcoded behavior; zero-config users see no change.

  Example for Azure Container Apps: tag_mappings: cloud_role_instance: [host.name, service.instance.id]

  Marked alpha; the schema may evolve.

• exporter/load_balancing: Add service, resource, and attributes routing key support for logs (#40223) Logs can now be routed using service (default, routes by service.name), resource (routes by full resource identity), or attributes (routes by configurable attribute values including log.severity and log.body pseudo attributes). This enables stateful downstream processing like log reduction, throttling, and tail-based sampling.

• exporter/opensearch: Add otel-v1 mapping mode that produces documents conforming to Data Prepper's OTel v1 index schemas, enabling interoperability with OpenSearch Observability dashboards. (#48585) Default index names match upstream Data Prepper conventions: otel-v1-apm-span for traces and otel-v1-logs for logs. Custom traces_index / logs_index overrides still apply, and dataset / namespace are not required when this mode is active.

• exporter/signalfx: Handle entity events as property updates sent to the PUT endpoint instead of PATCH. (#48469)

• extension/aws_logs_encoding: Add support for decoding VPC Flow Logs in Parquet format (#38861)

• extension/google_cloud_logentry_encoding: Migrate semantic conventions from v1.38.0 to v1.40.0 (#47547)

• extension/pebble_tail_storage: Promote pebble_tail_storage extension to alpha stability (#47916)

• extension/pebble_tail_storage: Drop DB on start (#48853) On startup, instead of returning an error if DB exists, drop the DB.

• pkg/coreinternal: Migrate semantic convention from v1.20.0 to v1.40.0 (#45295)

• pkg/coreinternal: Migrate db.system (v1.28.0) semantic convention to db.system.name (v1.40.0) (#45299)

• pkg/ottl: Substring function now supports UTF-8 safe slicing (#48436) New optional parameter utf8_safe (default: false). Set to true to adjust slice boundaries so multi-byte UTF-8 characters are never cut in the middle; the result may then be shorter than length bytes. Default preserves the existing byte-level slicing behavior.

• pkg/ottl: Add ottlexemplar context exposing per-exemplar fields (time, filtered_attributes, double_value, int_value, trace_id, span_id) for use in OTTL statements. (#47490)

• pkg/stanza: Add a none protocol option to the syslog parser that passes the message through without parsing its contents, for non-conforming syslog data. A leading PRI header is decoded when present, and RFC 6587 octet counting is supported. (#44795)

• pkg/zipkin: Migrate semantic conventions from v1.25.0 to v1.40.0 (#45089)

• processor/cumulativetodelta: Add internal telemetry for converted and dropped datapoints, and for tracked streams. (#48246) Three new metrics are emitted by the processor, all disabled by default (opt-in via the collector's service.telemetry.metrics configuration):

  • otelcol_cumulativetodelta_datapoints: number of datapoints converted from cumulative to delta temporality (with a metric_type attribute: sum, histogram, or exponential_histogram).
  • otelcol_cumulativetodelta_datapoints_dropped: number of datapoints dropped instead of converted, with the same metric_type attribute and a reason attribute (reset, initial, bucket_mismatch).
  • otelcol_cumulativetodelta_streams_tracked: number of metric streams currently tracked in memory.

  Reset detections also emit a Debug-level log line including the metric name, type, and datapoint attributes — logs absorb the per-stream cardinality that would be prohibitive on a metric while still letting operators identify which stream is wrapping/restarting.

• processor/gen_ai_normalizer: Add the custom source for user-defined GenAI attribute renames and value foldings. (#48677)

• processor/gen_ai_normalizer: Promote gen_ai_normalizer processor to alpha stability (#48773)

• processor/k8s_attributes: Add pod_delete_grace_period config option to configure pod metadata cache deletion grace period. (#48127) The pod_delete_grace_period config option defaults to 120s to match the previously hardcoded behavior.

• processor/lookup: Add A and AAAA lookup support for dns source of lookup processor (#48869)

• processor/lookup: Add traces and metrics support to the lookup processor. (#47777) Traces use ottlspan context (span-level lookups) and metrics use ottldatapoint context (datapoint-level lookups across all metric types).

• processor/resource_detection: Add k8s.cluster.uid detection to the k8s_api detector (formerly k8snode), derived from the kube-system namespace UID. (#48597) The k8s.cluster.uid attribute is enabled by default. To disable it, set resource_attributes.k8s.cluster.uid.enabled: false. The detector requires get permission on the kube-system namespace. If the permission is missing, a warning is logged and the attribute is omitted; other attributes are unaffected.

• processor/resource_detection: Updates github.com/GoogleCloudPlatform/opentelemetry-operations-go dependencies to their latest versions (v0.57.0 / v1.33.0). (#48894) This update brings in the following features:

  • Support OTLP event_name field in logs exporter
  • Add support for cloud run worker pools

• processor/spanpruning: Add attribute loss analysis to track diversity and missing attributes during span aggregation (#47671)

• processor/tail_sampling: Add a new processor_tail_sampling_count_bytes_sampled metric that counts bytes sampled per policy, mirroring processor_tail_sampling_count_spans_sampled. (#48348) Gated behind the processor.tailsamplingprocessor.metricstatcountbytessampled feature gate (alpha, disabled by default). Bytes are measured using the protobuf-marshaled ResourceSpans size, the same calculation used for maximum_trace_size_bytes.

• processor/tail_sampling: Allow nesting the not policy inside and_sub_policy for tail sampling policies. (#47313) This enables configurations such as "status_code: ERROR" AND NOT "http.status_code in [400, 499]" without relying on deprecated invert_match.

• processor/transform: Add the limit_buckets method to the merge_histogram_buckets OTTL function to reduce explicit histogram bucket counts. (#48527)

• receiver/aws_lambda: Decompress S3 objects based on .gz key suffix rather than gzip magic number sniffing (#38861) S3 objects are now decompressed only when their key ends in .gz. Objects without a.gz suffix are no longer auto-decompressed, even if their contents are gzip-encoded, and in that case the raw bytes will be passed to the configured decoder. This change avoids reading the file header to sniff the magic number, which is important for supporting formats such as Parquet that require random access.

• receiver/aws_lambda: Introduce metadata for derived logs and enrich client context with the same for CloudWatch logs. (#48581)

• receiver/azure_blob: Allow logs.encoding and traces.encoding to reference an encoding extension ID, in addition to the built-in otlp_json and otlp_proto values. (#48238) When encoding is set to a value other than otlp_json or otlp_proto, it is treated as the component ID of an encoding extension. The extension is resolved from the collector's configured extensions when the receiver starts and used to unmarshal blob payloads for that signal.

• receiver/azure_blob: Add encoding option per signal to accept OTLP/Protobuf in addition to OTLP/JSON blob payloads (#48236) Previously the receiver only accepted OTLP/JSON. New logs.encoding and traces.encoding options each accept otlp_json (default) or otlp_proto, selecting the encoding of blob payloads per signal. The default preserves prior behavior for existing OTLP/JSON producers.

• receiver/host_metrics: Add AIX to the system scraper's supported-OS allowlist. (#47095)

• receiver/k8s_events: Add dedup_interval config to throttle MODIFIED watch notifications per Event UID. (#48018) dedup_interval is opt-in (default 0 preserves existing behavior). When set to a positive duration, MODIFIED watch notifications for a given Event UID are emitted at most once per interval; ADDED notifications are always emitted. Set to a negative value to drop all MODIFIED notifications. Per-UID throttle state is retained for dedup_interval + 5m. Adds an internal telemetry counter otelcol.k8s.events.modified.filtered that tracks how many MODIFIED notifications were dropped by dedup_interval.

• receiver/k8s_objects: Add initial_delay to delay the first pull for pull-mode objects by an exact, per-object duration. (#48605) initial_delay lets operators stagger heavy pull-mode object collections across startup time without changing the configured recurring interval. If unset or 0, the receiver keeps the current immediate first-pull behavior. Watch-mode objects are unaffected.

• receiver/kafka: Add group_rebalance_strategies so consumers can advertise multiple partition assignment protocols in order during rolling deployments (#48658) Kafka picks the first protocol every group member supports. This avoids INCONSISTENT_GROUP_PROTOCOL when old and new collector pods temporarily advertise different assignment strategies. Order is preserved when configuring the franz-go client.

• receiver/oracledb: Add physical I/O and SQL*Net throughput metrics sourced from the existing v$sysstat scrape. (#48291) Adds four new opt-in metrics (disabled by default, stability: development) that surface previously discarded v$sysstat counters and establish the OTLP attributed metric pattern for the OracleDB receiver:

  • oracledb.physical_io.transferred (attributes: disk.io.direction, disk.io.type)
  • oracledb.physical_io.requests (attributes: disk.io.direction, disk.io.block_size)
  • oracledb.physical_io.cache_writes
  • oracledb.sqlnet.io.transferred (attributes: network.io.direction, destination.type) No new SQL queries are introduced; the existing SELECT * FROM v$sysstat scrape already returns all required rows, so there is zero additional load on monitored Oracle instances.

• receiver/oracledb: Add oracledb.plan.last_load and oracledb.plan_hash_value attributes to db.server.top_query events (#48216) Enhance db.server.top_query event with execution plan metadata:

  • oracledb.plan.last_load: Captures when the query execution plan was loaded
  • oracledb.plan_hash_value: Provides hash value for identifying similar execution plans These attributes enable plan stability monitoring, performance regression analysis, and query optimization workflows.

• receiver/oracledb: Add Oracle instance metadata as resource attributes and CDB/PDB detection at startup. (#48354) New resource attributes detected once at receiver startup (best-effort; failures are logged at Warn level):

  • oracle.db.version - Oracle version string (e.g. "19.0.0.0.0")
  • oracle.db.role - database role (e.g. "PRIMARY", "PHYSICAL STANDBY")
  • oracle.db.open_mode - open mode (e.g. "READ WRITE", "READ ONLY")
  • oracle.db.hosting_type - hosting environment: "self-managed", "RDS", or "OCI"
  • oracle.db.pdb - PDB name when connected directly to a PDB (empty for non-CDB or CDB root)

• receiver/oracledb: Add 12 new opt-in metrics from V$SYSMETRIC (group_id=2) covering buffer cache, CPU, library cache, shared pool, parse, and sort utilization. Parse and sort metrics include differentiating attributes. (#48381) New metrics (all disabled by default, stability: development): oracledb.buffer_cache.utilization, oracledb.database.cpu.utilization, oracledb.database.wait.utilization, oracledb.execution.utilization (with parse_type attribute), oracledb.host.cpu.utilization, oracledb.library_cache.utilization, oracledb.parse.rate (with parse_result attribute), oracledb.parse.utilization, oracledb.redo_allocation.utilization, oracledb.shared_pool.utilization, oracledb.sort.ratio (with sort_type attribute), oracledb.sql_service.response.duration

• receiver/oracledb: Add session wait event sampling (#48353) Add new opt-in log event db.server.session.wait_sample (disabled by default) that collects per-session wait event statistics from v$session_event. Includes session identifiers (sid, serial), wait event details (event, wait_class), and wait metrics (total_waits, time_waited).

• receiver/postgresql: Clean up the query_sample template to exclude our own connection and remove null query_start staements. (#47317)

• receiver/prometheus_remote_write: Replace manual scope hashing in metricIdentity and exemplarKey with identity.Scope and identity.Resource hash chaining, eliminating intermediate string allocations. (#48547)

• receiver/sqlquery: Report component status on database connection and query failures for health check v2 integration. (#43837)

• receiver/sqlserver: Add SQL compilation, parameterization, plan guidance, and attention metrics. (#48591) Adds the following new metrics (all disabled by default):

  • sqlserver.attention.rate: rate of SQL attentions (client cancellation interrupts).
  • sqlserver.parameterization.rate: rate of auto-parameterization activity, classified by result (auto_attempted, safe, unsafe, failed, forced).
  • sqlserver.plan.execution.rate: rate of plan executions, classified by plan guide result (guided, misguided).
  • sqlserver.recompilation.ratio: derived ratio of SQL recompilations to compilations, expressed as a percentage.

• receiver/sqlserver: Add Latch metrics for SQL Server receiver. (#48032) Added five new opt-in metrics:

  • sqlserver.latch.wait.rate — latch waits per second
  • sqlserver.latch.wait_time.avg — average latch wait time
  • sqlserver.latch.wait_time.total — total cumulative latch wait time
  • sqlserver.latch.superlatch.count — active superlatch count
  • sqlserver.latch.superlatch.transition.rate — superlatch promotions/demotions with transition.direction attribute

• receiver/sqlserver: Add Memory Manager metrics (memory areas, page pools, cache objects) consolidating 16 db-agent samplers into 3 metrics. (#48032) Added three new opt-in metrics:

  • sqlserver.memory.area with memory.pool attribute (target, total, sql_cache, optimizer, connection, granted_workspace, max_workspace)
  • sqlserver.memory.page.count with page.pool attribute (cache, total, target, database, stolen, reserved, free)
  • sqlserver.memory.cache.object.count with cache.state attribute (in_use, total)

• receiver/sqlserver: Add session attributes to db.server.query_sample event. (#48346) The db.server.query_sample log records now include:

  • sqlserver.client.app.name: Name of the client application that initiated the session.
  • sqlserver.session.start_time: ISO 8601 timestamp of when the session was established.
  • sqlserver.session.duration: Total elapsed time in seconds the session has been actively executing requests.

• receiver/statsd: receiver/statsd Add support for configuring socket buffer size (#47379)

• receiver/windows_event_log: Add EVTX file support (#48047)

🧰 Bug fixes 🧰

• cmd/opampsupervisor: Always send updated AgentDescription messages to the server when received from the collector (#48537)

• cmd/schemagen: Fix nil pointer dereference in parser when a type produces no schema element. (#48789)

• cmd/telemetrygen: Fix --allow-export-failures flag being ignored in batch mode for logs and metrics. (#47215)

• exporter/elasticsearch: Default mapping mode is now derived from the first allowed mode if otel is not included (#47907) Previously, when mapping::allowed_modes did not include otel, | the exporter would panic with a nil pointer dereference because the default mapping mode was always set to otel | regardless of the allowed modes.

• exporter/prometheus_remote_write: Fix 5xx responses being incorrectly classified as error_permanent="true" on otelcol_exporter_send_failed_metric_points_total (#48431)

• exporter/sentry: Validate organization and project slugs and URL-escape them when constructing Sentry API request paths. (#1) The exporter previously interpolated the configured org_slug and the runtime-derived project slug (from service.name) into Sentry API URL paths without validation or escaping.

• extension/azure_encoding: Map PIM event properties for Administrative Activity Logs (#47566) Azure PIM (Privileged Identity Management) events share the Administrative category with standard audit events but carry a different properties payload. All PIM-specific fields were silently dropped. This change adds explicit mappings for all known PIM fields: generic Azure concepts use cloud.account.id and azure.{tenant,resource}.* attributes, while PIM-specific fields use azure.pim.*. CallerInfo is projected to flat per-identity attributes (azure.pim.caller.upn, azure.pim.caller.object_id, azure.pim.caller.username, ...) keyed by the lowercased snake_case identity type.

• extension/text_encoding: Fix text encoding log unmarshalling for large messages when no unmarshaling separator is configured. (#48696)

• pkg/datadog: Use context available in function. (#48744)

• pkg/stanza: Fix EVT_HANDLE leak in Windows Event Log receiver when no checkpoint has been persisted (#47194) On a fresh start (no persisted checkpoint), Subscription stored a copy of the Bookmark struct whose EVT_HANDLE was allocated separately and never closed. The fix removes the bookmark field from Subscription entirely; RPC_S_INVALID_BOUND recovery is now handled by Input.readWithRetry, which has direct access to the Input's bookmark.

• processor/resource_detection: Remove outdated warning about GKE host.name not being available with Workload Identity (#48876)

• processor/tail_sampling: span-ingest: Clean up storage and memory for implicit unsampled traces after decision wait (#48874)

• receiver/awss3: Strip the .zst suffix from the object key after zstd decompression so files written by awss3exporter with compression: zstd (e.g. foo.binpb.zst) are correctly parsed instead of being dropped as "Unsupported file format". (#47802)

• receiver/host_metrics: Fix double-counting of CPU guest/guest_nice time, Linux already includes guest time within the user/nice fields (#48024)

• receiver/mysql: Aligned db.query.text extraction in MySQL sample query collection with top query collection for consistent query representation. (#48708) Along with change, the query plan hash will now be generated based on the digest text for MySQL versions < 8 and MariaDB.

• receiver/mysql: Fix USE and EXPLAIN FORMAT=json in explainQuery to execute on the same database connection, ensuring the schema context set by USE is visible to the subsequent EXPLAIN. (#48170) Previously, USE and EXPLAIN were issued on the connection pool without pinning, so they could land on different connections. Both statements now run on the same *sql.Conn acquired via db.Conn(ctx).

• receiver/otelarrow: Fix admission control bypass for requests with metadata but no data points (#45152) The receiver was bypassing admission control for requests with zero data points (spans/logs/metrics), even when such requests contained significant metadata. This allowed potential memory exhaustion by sending large volumes of resource and scope metadata without actual telemetry data.

• receiver/prometheus_remote_write: Fix exemplars for counters with multiple label-set variants being attached to the wrong datapoint. (#48674)

API Changelog

🛑 Breaking changes 🛑

• testbed: Split testbed/data{senders,receivers,connectors} into per-component sub-packages and move testbed.Components() to its own sub-package. (#48475) Each component now lives in its own Go package so test binaries only compile the senders, receivers, and connectors they actually exercise.
