This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.146.0
and the opentelemetry-collector-contrib v0.146.0 releases where appropriate.

🛑 Breaking changes 🛑

  • (Core) all: Increase minimum Go version to 1.25 (#14567)
  • (Contrib) all: Increase minimum Go version to 1.25 (#46000)
  • (Contrib) processor/k8s_attributes: Introduce semantic conventions compliant feature gate pair for k8sattributes processor (#44693)
    • Added processor.k8sattributes.EmitV1K8sConventions feature gate to enable stable semantic convention attributes (singular form: k8s.<workload>.label.<key> and k8s.<workload>.annotation.<key>)
    • Added processor.k8sattributes.DontEmitV0K8sConventions feature gate to disable legacy non-compliant attributes (plural form: k8s.<workload>.labels.<key> and k8s.<workload>.annotations.<key>)
    • Both feature gates are in alpha stage and disabled by default
    • The processor now validates that legacy attributes cannot be disabled without enabling stable attributes
    • Deprecated k8sattr.labelsAnnotationsSingular.allow feature gate in favor of the new semconv-compliant gates (will be removed in v0.150.0)
    • During migration period, both legacy and stable attributes can coexist when EmitV1K8sConventions is enabled but DontEmitV0K8sConventions is not
  • (Contrib) processor/resourcedetection: Promote processor.resourcedetection.propagateerrors feature gate to Stable and is now always enabled (#44609)
  • (Contrib) receiver/hostmetrics: process.context_switches will now properly count context switches for all threads. (#36804)
    Previously, only the lead thread's context switches would be counter. We believe this was a bug,
    but are marking it as a breaking change since the values of these metrics may change drastically
    compared to previous expectations. However, the values you get now will be more accurate than before.
  • (Contrib) receiver/kafkametrics: receiver.kafkametricsreceiver.UseFranzGo feature gate is now in Beta stage and enabled by default (#44600)

🚩 Deprecations 🚩

💡 Enhancements 💡

  • (Splunk) packaging: Update Splunk OpenTelemetry Java agent to v2.25.0 (#7249)
  • (Splunk) packaging: Update JMX metrics gatherer to v1.53.0 (#7082)
  • (Core) all: Add detailed failure attributes to exporter send_failed metrics at detailed telemetry level. (#13956)
    The otelcol_exporter_send_failed_{spans,metric_points,log_records} metrics now include
    failure attributes when telemetry level is Detailed: error.type (OpenTelemetry semantic convention
    describing the error class) and error.permanent (indicates if error is permanent/non-retryable).
    The error.type attribute captures gRPC status codes (e.g., "Unavailable", "ResourceExhausted"),
    standard Go context errors (e.g., "canceled", "deadline_exceeded"),
    and collector-specific errors (e.g., "shutdown").
    This enables better alerting and debugging by providing standardized error classification.
  • (Core) exporter/debug: Add output_paths configuration option to control output destination when use_internal_logger is false. (#10472)
    When use_internal_logger is set to false, the debug exporter now supports configuring the output destination via the output_paths option.
    This allows users to send debug exporter output to stdout, stderr, or a file path.
    The default value is ["stdout"] to maintain backward compatibility.
  • (Contrib) exporter/signalfx: Preserve 'k8s.service.' property names on the 'k8s.service.uid' dimension instead of converting them to 'kubernetes_service_' prefix. (#46291)
  • (Contrib) exporter/file: Add support for rotation when group_by is enabled in file exporter (#43143)
  • (Contrib) exporter/googlecloudstorage: Add compression support for Google Cloud Storage exporter (#45337)
    The Google Cloud Storage exporter now supports compression of log data before uploading to GCS.
    Supported compression algorithms: gzip and zstd.
  • (Contrib) exporter/kafka: Add conn_idle_timeout configuration option to control when idle connections are not reused and may be closed. (#45321)
    Defaults to 9 minutes.
  • (Contrib) pkg/ottl: Add IsInCIDR function to check if IP belongs to given list of CIDR (#42215)
  • (Contrib) pkg/stanza: Ensure filter operator does not split batches of entries (#42391)
  • (Contrib) processor/filter: Introduces inferred context conditions for filtering (#37904)
    Introduces three new top-level config fields [metric_conditions, log_conditions, trace_conditions].
    A user can supply OTTL conditions for each without needing to supply context.
  • (Contrib) processor/k8s_attributes: Added container.image.tags resource attribute with feature gate controls according to OpenTelemetry semantic conventions. (#44589)
  • (Contrib) receiver/hostmetrics: Add optional system.memory.linux.shared metric (#32712)
    This metric reports shared memory usage, including tmpfs filesystems,
    System V shared memory, and POSIX shared memory. Currently only available
    on Linux systems due to platform-specific data availability.
    This corresponds to the Shmem field in /proc/meminfo.
  • (Contrib) receiver/k8s_cluster: Add opt-in service metrics derived from k8s Service and EndpointSlice API (#45620)
    New metrics (disabled by default):
    • k8s.service.endpoint.count: Number of endpoints by condition (ready, serving, terminating), address type, and zone
    • k8s.service.load_balancer.ingress.count: Number of load balancer ingress points assigned to the service
      New resource attributes:
    • k8s.service.name: The k8s service name
    • k8s.service.uid: The k8s service uid
    • k8s.service.type: The k8s service type
    • k8s.service.traffic_distribution: The service's traffic routing preference
    • k8s.service.publish_not_ready_addresses: Whether the service publishes endpoints before pods are ready
  • (Contrib) receiver/kafka: Add conn_idle_timeout configuration option to control when idle connections are not reused and may be closed. (#45321)
    Defaults to 9 minutes.
  • (Contrib) receiver/mongodb: Add support for auth_mechanism, auth_source, and auth_mechanism_properties configuration options (#40686)
    Users can now specify the authentication mechanism (e.g., SCRAM-SHA-256, GSSAPI, MONGODB-AWS), auth source database,
    and auth mechanism properties when connecting to MongoDB instances. This is particularly useful for MongoDB servers
    that require specific authentication mechanisms. For example, GSSAPI (Kerberos) may require SERVICE_NAME, and
    MONGODB-AWS may require AWS_SESSION_TOKEN when using temporary AWS credentials.
  • (Contrib) receiver/prometheusremotewrite: Improved performance when parsing Remote Write v2 requests. (#45623)
  • (Contrib) receiver/prometheusremotewrite: Add exemplar support to the Prometheus Remote Write receiver (#44983)
  • (Contrib) receiver/sqlquery: Add support for initial_delay in logs collection. (#29671)
    Log collection now applies initial_delay (previously ignored). If initial_delay is not set, the first log collection now occurs at 1 second, instead of occurring after collection_interval time has passed.
  • (Contrib) receiver/sqlserver: Add the sqlserver.procedure_id and sqlserver.procedure_name attributes to TopQuery and Sample Events (#44656)
    Refined query and reported events to include stored procedure information when applicable. Additionally, the maximum number of active queries reported by default has been increased from 200 to 250 to account for record deaggregation introduced by this change, ensuring the effective limit remains consistent with the previous 200-query baseline.
  • (Contrib) receiver/statsd: Discard StatsD metrics with NaN or infinite values to prevent invalid data from entering the metric pipeline (#44288)
  • (Contrib) receiver/syslog: Add facility_text attribute to syslog parser output (#45641)
    The syslog parser now outputs a facility_text attribute containing
    the human-readable facility name (e.g., "auth", "kern", "local0")
    in addition to the existing numeric facility attribute.

🧰 Bug fixes 🧰

  • (Core) pkg/config/confighttp: Fix high cardinality span name from request method from confighttp server internal telemetry (#14516)
    Follow spec to bound request method cardinality.
  • (Core) pkg/otelcol: Ignore component aliases in the otelcol components command (#14492)
  • (Core) pkg/otelcol: Order providers and converters in alphabetical order in the components subcommand. (#14476)
  • (Contrib) extension/oauth2client: Fix oauth2clientauth client-credentials grant type (#45786)
  • (Contrib) extension/text_encoding: Fix text encoding extension to not split large messages when no separator is configured. (#45845)
  • (Contrib) pkg/stanza: Fix recombine operator logging errors at ERROR level when on_error is set to quiet mode (#42646)
  • (Contrib) pkg/translator/prometheusremotewrite: Fix export of Instrumentation Scope attributes as Prometheus labels. (#45912)
    Instrumentation Scope attributes (name, version, and other attributes) are now correctly translated to Prometheus labels with the otel_scope_ prefix.
  • (Contrib) processor/k8s_attributes: Fix concurrent map access panic by cloning pod labels and annotations before extraction. (#46112)
  • (Contrib) processor/k8s_attributes: Allow key_regex to work without tag_name by using the default tag name format (#45719)
    When using key_regex with capturing groups but without specifying tag_name, the processor now
    correctly uses the default tag name format (e.g., k8s.pod.labels.<label_key>) instead of
    producing empty tag names.
  • (Contrib) processor/redaction: Improve database sanitization with system-aware obfuscation, span name sanitization, and URL path parameter redaction. (#44229)
    • Database sanitization now validates span kind (CLIENT/SERVER/INTERNAL ) and requires db.system.name/db.system attribute for traces/metrics
    • Implemented span name obfuscation for database operations based on db.system
    • Added URL path parameter sanitization for span names with configurable pattern matching
    • Improved query validation database sanitizers
    • Fix issue ensuring no spans with ... name can be generated due to enabling multiple sanitizers
    • If something went wrong during span name sanitization, original span name is used
  • (Contrib) receiver/azure_event_hub: Fixes a bug where the receiver would stop receiving messages after a parsing error. (#45898)
  • (Contrib) receiver/fluentforward: handle uint64 to int64 overflow by changing to string (#45252)
    FluentD supports record entries with uint64 types. OpenTelemetry log attributes only support int64 and no uint64.
    The old solution would overflow with uint64 values greater than math.MaxInt64 and result in negative attribute values.
    This fix changes that behaviour by storing only those large values as string attributes instead.
  • (Contrib) receiver/googlecloudpubsub: Fix compression detection when both encoding and compression are set in the config (#45810)
  • (Contrib) receiver/mongodb: Check if metrics are enabled before collecting them to prevent errors when metrics are disabled. (#41465)
  • (Contrib) receiver/postgresql: Updated the default value for top_n_query (200) to match with other db receivers (#45612)
