extension/pebble_tail_storage: First PR for new Pebble tail storage extension (#47916)processor/drain: Add drain processor that applies the Drain log clustering algorithm to annotate log records with a derived template string. (#47235)The processor sets
log.record.template(e.g."user <*> logged in from <*>") on each log record.Downstream processors such as the filter processor can act on this attribute to, for example, drop
entire classes of noisy logs by template string.
Key features:
passthroughwarmup mode (default) andbufferwarmup mode that holds records until the tree has stabilizedreceiver/azure_functions: Initial implementation of the Azure Functions receiver to ingest logs from Azure Functions triggered by Event Hub. (#43507)💡 Enhancements 💡

exporter/clickhouse: Update the default logs table schema with an improved ORDER BY, materialized k8s/deployment attribute columns, and automatic ClickHouse 26.2+ full text search index selection. (#47720)The logs table DDL now uses
ORDER BY (toStartOfFiveMinutes(Timestamp), ServiceName, Timestamp)and includes a set ofmaterialized
__otel_materialized_*columns for common k8s/deployment resource attributes.When connecting to ClickHouse 26.2+, the exporter creates
TYPE text()indexes for full text search on attributes and body;on older versions it falls back to
bloom_filter/tokenbf_v1indexes. Existing tables are not modified(
CREATE TABLE IF NOT EXISTS), and the INSERT path remains compatible with both the old and new schemas.exporter/datadog: Includeservice.instance.idin OTLP resource attribute to Datadog metric tag mapping so it is sent as a metric tag by default. (#47936)service.instance.idis required to enable OTel traffic metrics on Datadog Fleet Automation.This change adds it to coreMapping so it is emitted as a Datadog metric tag when converting OTLP resource attributes.
exporter/elasticsearch: Refactor profiles attribute handling (#47801)The Profiles signal changed the handling of attributes and moved resource attributes from Sample
to ResourceProfiles. Refactor attribute handling in elasticsearch exporter to reflect this change.
exporter/prometheusremotewrite: Add support for translation_strategy, which supports UnderscoreEscapingWithSuffixes, UnderscoreEscapingWithoutSuffixes, NoUTF8EscapingWithSuffixes, and NoTranslation. (#33661)exporter/prometheusremotewrite: Add support for exemplar labels when using PRW 2.0 (#33661)exporter/signalfx: Add support for PersistentVolume and PersistentVolumeClaim entity property updates. (#47829)Handle k8s.persistentvolume and k8s.persistentvolumeclaim entities in both the
metadata update and entity events paths. Label prefix stripping is skipped for
these entities to preserve full property key names.
exporter/signalfx: APM correlation now recognizesdeployment.environment.namein addition to the deprecateddeployment.environmentattribute (#47862)extension/aws_logs_encoding: Migrate CloudTrail log semconv RPC attributes from v1.38.0 to v1.40.0 via feature gates (#47549)extension/aws_logs_encoding: Added auto-detection support for AWS Transit Gateway flow logs (#46229)The VPC flow log unmarshaler now automatically detects and handles Transit Gateway (TGW) flow logs from S3.
Detection is based on the presence of the "resource-type" field in log file headers.
TGW-specific fields (tgw-src-vpc-id, tgw-dst-vpc-id, etc.) are now supported and mapped to appropriate attributes.
No configuration changes required - auto-detection works with default vpcflow format settings.
extension/azure_encoding: Add encoding.format scope attribute for metrics based on Azure resource provider (#47537)extension/azure_encoding: Migrate semantic conventions to v1.40.0 (#47543)extension/health_check: Enable keep-alives for the health check extension's HTTP and gRPC servers.

(#47873)pkg/ottl: Enhanced XML parsing by limiting the maximum XML nesting depth. (#47766)pkg/ottl: Added debug-level logging when functions truncate or discard attributes (#9730)Added logging to the
truncate_allandlimitfunctions for each record that had attributes truncated or discarded, as per the OpenTelemetry specification on attribute limitspkg/stanza: Timestamp operator - Add support for multiple timezone parsing (#47594)pkg/zipkin: Migrate semantic conventions to v1.40.0 (#47545)processor/drain: Promote Drain Processor from development to alpha stability and add to contrib distribution. (#47235)processor/k8s_attributes: Allow k8sattributes processors to be shared between pipelines (#36234)When the processor.k8sattributes.ShareProcessorBetweenPipelines feature flag is enabled, k8sattributes processors
using the same configuration are shared between pipelines. This reduces the local cache size and the number of
connections to the K8s API Server.
processor/schema: Make CacheableProvider cooldown and retry limit configurable viacache_cooldownandcache_retry_limit. (#47761)processor/spanpruning: Add cumulative histogram bucket support for latency distribution on aggregated summary spans (#47277)processor/tail_sampling: Add distributed tracing instrumentation totailsamplingprocessorto provide visibility into trace processing behavior and policy evaluation (#43931)Adds trace spans for key operations:
tailsampling.ConsumeTraces: Tracks incoming traces/spans counttailsampling.samplingPolicyOnTick: Records batch processing metrics and policy evaluation resultsprocessor/transform: Added extract_percentile_metric function to Transform processor for extracting percentiles as gauge metrics from histograms. (#44316)receiver/awslambda: Add multi-format S3 log routing via the newencodingsfield in the S3 receiver configuration. (#46458)The new
encodingslist field enables a single Lambda deployment to route S3 objects todifferent decoders based on their key prefix.
receiver/awss3: add a flag to the s3 receiver to skip objects previously tagged as ingested. (#47396)receiver/chrony: Enables dynamic metric reaggregation in the Chrony receiver. This does not break existing configuration files. (#46350)receiver/chrony: Add file_mount_path config option for cross-namespace Unix datagram socket communication (#46833)When the collector and chronyd run in separate containers with different network
namespaces, Go's default abstract socket autobind fails because abstract sockets
are namespace-scoped. The new file_mount_path option uses a directory on a shared
volume to bind a random client socket, allowing chronyd to reply across namespaces.
receiver/datadog: Migrate semantic conventions to v1.40.0 (#47551)receiver/github: Promote traces toalphastability (#47894)receiver/github: Addjob.check_run_iddeterministic spans via thereceiver.githubreceiver.UseCheckRunIDfeature gate (#44856, #45157)Feature gate
receiver.githubreceiver.UseCheckRunIDderives job, step, andqueue span IDs from the GitHub
check_run_idinstead of the workflow jobname. This allows in-action telemetry tools to reproduce matching span IDs by
leveraging
${{ job.check_run_id }}and name exclusively instead of callingthe GitHub REST API. Trace ID and root span ID are unchanged. Webhook payloads
missing
workflow_job.idare rejected while the gate is enabled; set the gateto disabled to accept them under the legacy scheme.
receiver/googlecloudpubsub: Add debug log of the pubsub message when an encoding error occurs. (#46662)When the configured encoder fails to decode a Pub/Sub message, a debug-level
log is now emitted containing the message ID, attributes, and the underlying
error. This log is emitted regardless of the
ignore_encoding_errorsetting,making it easier to diagnose which messages are causing decoding failures.
receiver/host_metrics: Add AIX to the process scraper's supported-OS allowlist. The AIX-specific scraper implementation is added separately. (#47095)receiver/icmpcheckreceiver: Enables dynamic metric reaggregation in the ICMP Check receiver. This does not break existing configuration files. (#46359)receiver/journald: Log the full journalctl command which facilitates debugging. (#45619)receiver/k8s_cluster: Add PersistentVolume and PersistentVolumeClaim metrics, entity events, and metadata support. (#47453)New metrics (all disabled by default):
k8s.persistentvolume.status.phase,k8s.persistentvolume.storage.capacity,k8s.persistentvolumeclaim.status.phase,k8s.persistentvolumeclaim.storage.request,k8s.persistentvolumeclaim.storage.capacity.New entity types:
k8s.persistentvolume,k8s.persistentvolumeclaim.receiver/k8s_events: Add resource version persistence to the k8s_events receiver to prevent duplicate events on collector restart. (#47575)A new
storageconfiguration option accepts a storage extension ID (e.g.file_storage).When configured, the receiver persists the latest resourceVersion after each watch event and
resumes from it on restart, preventing duplicate events. The persisted resourceVersion is
scoped per namespace, matching the behavior added to the k8sobjects receiver in #46543.
receiver/k8s_events: Expose reporting controller and reporting instance as part of kubernetes events (#45289)This change adds a reporting controller and reporting instance to the kubernetes events receiver.
This allows for better monitoring and reporting of events collected by the receiver.
receiver/k8s_objects: Whenstorageis configured, watch-mode objects automatically resume from the last seen resourceVersion across restarts, preventing event duplication. (#46543)receiver/mongodb_atlas: Enables dynamic metric reaggregation in the MongoDB Atlas receiver. This does not break existing configuration files. (#46365)receiver/mysql: Add MySQL <8 and MariaDB compatibility for query sample and top-query collection. The receiver now detects the server product and version at connect time and gates behavior accordingly. Changes include: (1) top-query collection uses a fallback template on MySQL <8 and MariaDB that omitsquery_sample_text(absent on those versions); (2)client.portandnetwork.peer.portare now populated on MySQL 8.0.22+ via a lock-free join onperformance_schema.processlist, and remain 0 on older MySQL and all MariaDB versions where this table is unavailable; (3)mysql.events_waits_current.timer_waitnow uses a three-tier fallback — exactTIMER_WAITfor completed waits, a PS timer approximation for in-progress waits on MySQL 5.7+/8.0+, andthread.processlist_time(integer-second precision) as a universal fallback for MariaDB and older MySQL.(#47302)
Supported products and versions: MySQL 5.7.3+, 8.0+; MariaDB 10.5.2+, 11.x.
See COMPATIBILITY.md in the receiver directory for a full version × feature matrix.
receiver/mysql: Addmysql.events_statements_current.timer_waitattribute todb.server.query_sampleevents, exposing the elapsed execution time of the sampled statement in seconds. (#47529)On MariaDB and for in-flight MySQL statements where
TIMER_WAITis unavailable,PROCESSLIST_TIMEis used as a fallback.receiver/nginx: Enable the re-aggregation feature for the nginx receiver (#46368)receiver/osquery: Promote the osquery receiver to alpha (#47498)receiver/prometheus_remote_write: Translate prometheus metric unit names per opentelemetry spec. (#46984)receiver/prometheus_remote_write: Add support for translating PrometheusInfoandStateSettyped metrics to OTLP Non-Monotonic Sums. (#47727)receiver/prometheus_remote_write: Handle allotel_scope_*prefixed labels per the Prometheus/OTLP compatibility spec. (#47726)otel_scope_schema_urlis now set as the instrumentation scope schema URL, and otherotel_scope_<attr>labels become scope attributes (with theotel_scope_prefix stripped), instead of being incorrectly added as metric data point attributes.receiver/receiver_creator: Makes the default file_log config configurable on the receiver creator discovery feature. (#40769)receiver/redfish: Enables dynamic metric reaggregation in the Redfish receiver. This does not break existing configuration files. (#46375)receiver/sqlquery: Addignore_null_valuesconfig option to suppress NULL value warning logs (#43985)receiver/sqlserver: Enrichesdb.server.query_samplelog records in the SQL Server receiver with wait-derived fields by addingsqlserver.blocking.start_time,sqlserver.wait.resource.type,sqlserver.wait.resource.id, andsqlserver.lock.type.

(#46383)🧰 Bug fixes 🧰
exporter/alibabacloud_logservice: Bump aliyun-log-go-sdk to v0.1.100, fixing SA1019 lint warning from deprecated producer.InitProducer (#44363)Migrates to producer.NewProducer which returns an error, allowing initialization failures to propagate correctly.
exporter/clickhouse: Quote cluster_name in ON CLUSTER clause to support names with special characters (e.g. dashes), preventing schema creation failures. (#46946)exporter/datadog: Fix the dual shipping issue for orchestrator explorer in the datadog exporter. (#47877)exporter/prometheus: Drop reserved instrumentation scope attributes from Prometheus exporter labels to avoid conflicts with scope metadata labels. (#47924)exporter/prometheusremotewrite: Scope attributes "name", "version", and "schema_url" are dropped to prevent conflicts with the scope's name, version, and schema url fields. (#47683)exporter/prometheusremotewrite: Fix bug where non-monotonic sums are mapped to Prometheus counters instead of gauges. (#33661)exporter/prometheusremotewrite: Respect the zero threshold of exponential histograms when set for PRW v2 (#33661)exporter/prometheusremotewrite: Skip attributes with empty string values when converting OTLP metrics to Prometheus labels. (#47326)Attributes and resource attributes with empty string values are now excluded
from Prometheus label conversion, preventing empty labels from being created.
exporter/signalfx: Fix incorrecthost_physical_cpusandhost_cpu_coresvalues reported on Linux (#47550)exporter/splunk_hec: Fix HEC routing partitioning broken when the exporterhelper batcher is enabled (#47695)extension/azure_auth: Fix server-side authentication bypass by validating bearer tokens as OIDC JWTs with a server-pinned issuer and audience. (#47823)Versions v0.124.0 through v0.150.0 accepted any bearer token that matched a token minted from the collector's own identity for a scope chosen by the client
Hostheader, allowing authentication bypass and scope confusion.The receiver auth path now verifies the JWT signature against the issuer's JWKS and checks
iss,aud,exp, andnbf. The audience is pinned from configuration and is never derived from request headers.Breaking change: using
azure_authunder a receiverauth:block now requires the newserver.issuer_urlandserver.audiencesettings. Exporter-only usage is unaffected.extension/azure_encoding: Fix parsing of all App Service and Function App log categories when properties field is a stringified JSON string instead of an object. (#47539)Some Azure Event Hub sources emit the properties field as a JSON string rather than an object.
This caused App Service log categories (AppLogs, AuditLogs, AuthenticationLogs, ConsoleLogs,
HTTPLogs, IPSecAuditLogs, PlatformLogs, FileAuditLogs) to fall back to raw log storage,
losing all semantic attributes.
extension/bearertokenauth: Replace custom file watching implementation with the shared credentialsfile helper, fixing defect with k8s secrets rotation (#46470, #45953)extension/google_cloud_logentry_encoding: Add the deprecated name of the googlecloudlogentryencoding extension as a deprecated option to the factory. (#47663)This was one of several components renamed in v0.148.0.
pkg/ottl: Added validation for substring function to ensure start and length parameters do not exceed the target string length. (#47764)pkg/ottl: Improve performance for decode function and fix ValueBytes decoding (#47685)pkg/ottl: Fixscope.schema_urlandresource.schema_urlpaths resolving to the same value in OTTL when evaluated by thescopecontext. Both paths now correctly return their independent schema URLs as defined in OTLP. (#47784)processor/k8s_attributes: Fix steady memory growth caused by map bucket retention in high-churn clusters. (#47337)Compacts the pods map incrementally to avoid memory leaks.
processor/k8s_attributes: Fix service.name annotation not taking precedence over labels when otel_annotations is enabled. (#47534)Restored correct precedence order so that resource.opentelemetry.io/service.name annotation
takes priority over app.kubernetes.io/name label, as documented in OTel semantic conventions.
processor/schema: Fix mutex held during HTTP schema fetch, serialising concurrent schema retrievals (#47633)The CacheableProvider held its mutex for the entire duration of HTTP schema fetches.
Concurrent requests for uncached schemas would block on each other rather than
fetching in parallel. The lock is now released before the HTTP call and re-acquired
only to write the result to the cache and update internal state.
processor/schema: Skip uninitialised metrics (MetricTypeEmpty) instead of returning an unsupported metric type error (#47428)processor/schema: Fix rate-limit reset in CacheableProvider allowing burst of calls after cooldown expires, and log prefetch errors instead of silently discarding them (#47428)processor/schema: Fix panic on malformed schema span_events and inconsistent error handling across signal types (#47634)A panic in newSpanEventChangeList when a span_events entry had neither rename_events
nor rename_attributes set has been replaced with a proper error return. Error handling
across all signal types (logs, traces, metrics) is now consistent: any scope-level
translation failure returns the error immediately rather than silently continuing.
A context.Background() in processMetrics was also replaced with the pipeline context.
processor/schema: Fix upgrade path silently applying no changes due to fetching the incoming signal's schema file instead of the target schema file (#47427, #47632)When upgrading a signal to a newer target version, the processor was fetching the schema
file at the incoming signal's URL. Because OTel schema files only contain history up to
their own version, the translator found no applicable revisions and silently passed the
signal through unchanged. The processor now fetches the target schema URL on the upgrade
path, which contains the complete forward migration history.
processor/spanpruning: Avoid excessive memory usage on large and fragmented traces (#47771)processor/spanpruning: Fix bug in span pruning where spans with the same name at different depths could become orphaned instead of deleted. (#47770)receiver/azure_monitor: Fix StartTimestamp being greater than Timestamp in batch API path (#47705)receiver/cisco_os: Add the deprecated name of the ciscoos extension as a deprecated option to the factory. (#47666)This was one of several components renamed in v0.148.0.
receiver/datadog: Fix invalid temporality and type combination for dd.internal.stats.payload metric by setting AggregationTemporality to Cumulative (#46937)The dd.internal.stats.payload metric is now correctly configured with AggregationTemporalityCumulative,
which was previously missing and causing OTLP validation errors when exporting metrics.
receiver/github: Fix the enforcement of configuredrequired_headerson incoming webhook requests. (#47854)receiver/github: Add configurable retry with exponential backoff for transient GitHub API errors (429, 502, 503, 504, secondary rate limits) (#43388)receiver/gitlab: Skip stages with an emptyStartedAttimestamp (e.g. from early-failed pipelines where a stage was queued but never executed), preventing the "invalid startedAt timestamp: time is empty" error. (#45756)receiver/kafka: Resume paused partitions after backoff delay and on reassignment after rebalance (#47118)When message_marking.after=true and message_marking.on_error=false, non-permanent
processing errors (e.g. from memorylimiter) caused PauseFetchPartitions to be called
but ResumeFetchPartitions was never called, leaving partitions paused forever.
Partitions are now automatically resumed after the configured error_backoff.initial_interval
delay when error_backoff is enabled. Additionally, partitions paused across rebalances
are resumed via ResumeFetchPartitions in the assigned callback, since franz-go persists
the pause state by design.
receiver/mongodb_atlas: Fix include_clusters/exclude_clusters filtering having no effect. (#47037)receiver/postgresql: Refined the collector query to filter out null parameter entries, minimizing null-related warnings in receiver. (#47768)receiver/windows_event_log: Support the deprecated name windowseventlog for the windows_event_log receiver. (#47773)This is a fix for a bug in the recent receiver rename in #47359

pkg/ottl: Return errors when OTTL context accessors receive values of the wrong type (part 2) (#40198)Setters in OTTL contexts now validate that values are of the expected type and return
descriptive errors when type mismatches occur. This is the continuation of work done in
#43505, addressing remaining contexts: datapoint, profile, profilesample, resource, span,
and spanevent.
Changes include:
now use SetCommonTypedSliceValues/SetCommonIntSliceValues for better type handling.
Note: Users may see new errors from OTTL statements that were previously silently failing
due to type mismatches. These errors indicate pre-existing issues in OTTL configurations that
were not being applied as expected.
processor/resourcedetection: Remove feature gate processor.resourcedetection.propagateerrors (#45853)processor/transform: Remove theprocessor.transform.ConvertBetweenSumAndGaugeMetricContextfeature gate. (#47358)This feature gate has been stable for over a year and is no longer used in any code paths.
receiver/k8s_cluster: Kubernetes resource labels in entity events are now prefixed per OTel semantic conventions. (#47491)Labels on Kubernetes resources emitted as entity event attributes are now prefixed with
k8s.<resource>.label.to align with OTel semantic conventions (e.g.k8s.pod.label.<key>,k8s.node.label.<key>,k8s.deployment.label.<key>, etc.).Previously, label keys were emitted verbatim without any prefix.
Users consuming entity event attributes by label key will need to update their configurations.
receiver/kubeletstats: Disable deprecated resource attributes by default (#47184)The following resource attributes are deprecated and will now be disabled by default:
aws.volume.id,fs.type,gce.pd.name,glusterfs.endpoints.name,glusterfs.path, andpartition.All of these attributes will be removed in a future release.

This simplifies common patterns where a canonical attribute must be resolved from multiple possible sources.
Example:
set(attributes["user"], Coalesce([attributes["user.id"], attributes["enduser.id"], "unknown"]))pkg/stanza: Optimizing the performance of Windows Event log unmarshalling when raw = true (#47164)pkg/stanza: Add new scrape model for Windows event logs using an event-driven subscription instead of polling (#47091)pkg/stanza: Addon_truncateoption to fileconsumer to control behavior when a file's stored offset exceeds its current size. (#43693)processor/filter: Add feature gateprocessor.filter.defaultErrorModeIgnoreto change default error_mode to ignore (#47232)processor/interval: Flush remaining buffered metrics on shutdown to prevent data loss during restarts and rollouts. (#47238)Previously, the interval processor would silently drop any metrics accumulated
in its buffer when receiving a shutdown signal. Now it flushes the buffer to
the next consumer before exiting, consistent with the batch processor behavior.
processor/lookup: Add DNS lookup source and LRU caching (#46114)Adds a DNS source that performs reverse DNS lookups (PTR records) to resolve IP addresses to hostnames.
Implements a full LRU cache with size-based eviction, TTL expiration, and negative caching.
The DNS source has caching enabled by default.
processor/spanpruning: Add full implementation of the span pruning processor. (#45654)processor/tail_sampling: Add gated tail storage extension support to tailsampling processor via new tail_storage config (#45250)Introduces a new tail storage interface with in-memory default behavior and allows extension-backed storage when
the processor.tailsamplingprocessor.tailstorageextension feature gate is enabled.
processor/transform: Add feature gateprocessor.transform.defaultErrorModeIgnoreto change default error_mode to ignore (#47231)processor/transform: Add support for semantic conventions 1.38.0, 1.39.0, and 1.40.0 in theset_semconv_span_namefunction. (#45911)The
set_semconv_span_namefunction now recognizes semantic conventions 1.38.0, 1.39.0, and 1.40.0, allowing span names to be determined using the latest rules. Support for therpc.system.nameattribute (introduced in 1.39.0) has been added so span names can reflect the new RPC system conventions. Backward compatibility is preserved: therpc.systemattribute remains supported.receiver/active_directory_ds: Enables dynamic metric reaggregation in the Active Directory Domain Services receiver. This does not break existing configuration files. (#46346)receiver/apachespark: Enable the re-aggregation feature for the apachespark receiver (#46349)receiver/awss3: addtag_object_after_ingestionflag to the s3 receiver so objects that have been processed can be identified (#46078)They will be tagged with
otel-collector:status=ingested. Operators can use that tag to define bucket lifecycle policies.receiver/awss3: add zstd decompression to the s3 receiver (#46854)receiver/cloudfoundry: Migrate cloudfoundry.resourceAttributes.allow feature gate registration from manual code to metadata.yaml for mdatagen code generation (#46116)receiver/elasticsearch: Enable dynamic attribute metric with attribute re-aggregation in configuration at runtime (#46353)receiver/filestats: Enable re-aggregation and set requirement levels for attributes. (#46355)receiver/googlecloudpubsub: Add flow control configuration (#44804)Add flow control configuration, giving advanced users more control over the parameters of the streaming
pull control loop.
receiver/k8s_cluster: Emit entity references as part of metrics resources. (#41080)receiver/k8sobjects: Addkube_api_qpsandkube_api_burstconfig options to control Kubernetes API request rate limits and prevent client-side throttling when watching or polling many resources (#44484)The same fields are also available in
receiver/k8seventsvia the sharedinternal/k8sconfigpackage.Default values match the client-go defaults:
kube_api_qps=5,kube_api_burst=10.receiver/receiver_creator: add support for profiling signal for receiver creator (#46930)receiver/splunkenterprise: Add custom search support to the Splunk Enterprise receiver (#47124)receiver/windows_event_log: Adddiscover_domain_controllersconfig flag to automatically discover and collect Security events from Active Directory domain controllers based on feature gate domainControllers.autodiscovery.
