signalfx/splunk-otel-collector v0.150.0

on GitHub

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.150.0
and the opentelemetry-collector-contrib v0.150.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) core: Update default endpoint URLs in collector configs and Go runtime defaults from *.signalfx.com to *.observability.splunkcloud.com. (#7412)
  For full migration details, proxy/firewall configuration notes, and per-tool instructions for
  keeping legacy *.signalfx.com endpoints, see the
  0.149.0 → 0.150.0 upgrade guideline in README.md.
• (Splunk) installer: Update installer scripts and packaging to use *.observability.splunkcloud.com URLs instead of *.signalfx.com. (#7413)
  For full migration details, proxy/firewall configuration notes, and per-tool instructions for
  keeping legacy *.signalfx.com endpoints, see the
  0.149.0 → 0.150.0 upgrade guideline in README.md.
• (Contrib) 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:
  • Slice setters (explicit_bounds, bucket_counts, positive.bucket_counts, negative.bucket_counts)
    now use SetCommonTypedSliceValues/SetCommonIntSliceValues for better type handling.
  • SetMap now returns an error for invalid value types instead of silently ignoring them.
    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.
• (Contrib) processor/resourcedetection: Remove feature gate processor.resourcedetection.propagateerrors (#45853)
• (Contrib) processor/transform: Remove the processor.transform.ConvertBetweenSumAndGaugeMetricContext feature gate. (#47358)
  This feature gate has been stable for over a year and is no longer used in any code paths.
• (Contrib) 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.
• (Contrib) 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, and partition.
  All of these attributes will be removed in a future release.

🚩 Deprecations 🚩

• (Splunk) smartagent/memcached: The memcached monitor is deprecated. (#7414)
  Please use the memcached receiver instead.
• (Splunk) envvarconfigsource: Deprecate the Splunk distribution of the envvar config source. (#7319)
  This environment variable config source is deprecated in favor of the upstream configuration source for environment variables.
  Please use the env:ENV_VAR:-default notation to set the default value of the environment variable.
  See https://github.com/open-telemetry/opentelemetry-collector/tree/main/confmap/provider/envprovider
• (Contrib) receiver/http_check: Rename httpcheck receiver to http_check with deprecated alias httpcheck (#45339)
• (Contrib) receiver/tcp_log: Rename tcplog receiver to tcp_log with deprecated alias tcplog (#45339)
• (Contrib) receiver/tls_check: Rename tlscheck receiver to tls_check with deprecated alias tlscheck (#45339)
• (Contrib) receiver/udp_log: Rename udplog receiver to udp_log with deprecated alias udplog (#45339)
• (Contrib) receiver/windows_event_log: Rename windowseventlog receiver to windows_event_log with deprecated alias windowseventlog (#45339)

💡 Enhancements 💡

• (Contrib) exporter/kafka: Add record_headers configuration option to set static headers on outgoing records (#47193)
• (Contrib) exporter/kafka: Add support for partitioning kafka records (#46931)
  Add support for RoundRobin and LeastBackup partitioning strategies, as well as custom partitioners
  provided by RecordPartitionerExtension implementations. Users can implement their own partitioning logic
  and plug it into the kafka exporter via the RecordPartitionerExtension interface.
• (Contrib) exporter/signalfx: Add dimension_client::strip_k8s_label_prefix option to strip k8s.<resource>.label. prefix from dimension property updates. (#47491)
  The k8s cluster receiver now emits Kubernetes resource labels in entity events with the
  k8s.<resource>.label. prefix per OTel semantic conventions (e.g. k8s.pod.label.app).
  When strip_k8s_label_prefix: true (the default), the SignalFx exporter strips this prefix
  when forwarding labels as dimension properties, preserving the existing SignalFx behavior (e.g. app).
  Set strip_k8s_label_prefix: false to disable stripping and receive the full prefixed keys.
• (Contrib) extension/health_check: Migrate extension.healthcheck.useComponentStatus feature gate registration from manual code to metadata.yaml for mdatagen code generation (#46116)
• (Contrib) pkg/ottl: Add Coalesce converter that returns the first non-nil value from a list of arguments. (#46847)
  The Coalesce converter accepts a list of values and returns the first one that is not nil.
  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"]))
• (Contrib) pkg/stanza: Optimize the performance of Windows Event log unmarshalling when raw = true (#47164)
• (Contrib) pkg/stanza: Add new scrape model for Windows event logs using an event-driven subscription instead of polling (#47091)
• (Contrib) pkg/stanza: Add on_truncate option to fileconsumer to control behavior when a file's stored offset exceeds its current size. (#43693)
• (Contrib) processor/filter: Add feature gate processor.filter.defaultErrorModeIgnore to change default error_mode to ignore (#47232)
• (Contrib) 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.
• (Contrib) processor/transform: Add feature gate processor.transform.defaultErrorModeIgnore to change default error_mode to ignore (#47231)
• (Contrib) processor/transform: Add support for semantic conventions 1.38.0, 1.39.0, and 1.40.0 in the set_semconv_span_name function. (#45911)
  The set_semconv_span_name function 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 the rpc.system.name attribute (introduced in 1.39.0) has been added so span names can reflect the new RPC system conventions. Backward compatibility is preserved: the rpc.system attribute remains supported.
• (Contrib) receiver/active_directory_ds: Enables dynamic metric reaggregation in the Active Directory Domain Services receiver. This does not break existing configuration files. (#46346)
• (Contrib) receiver/apachespark: Enable the re-aggregation feature for the apachespark receiver (#46349)
• (Contrib) receiver/cloudfoundry: Migrate cloudfoundry.resourceAttributes.allow feature gate registration from manual code to metadata.yaml for mdatagen code generation (#46116)
• (Contrib) receiver/elasticsearch: Enable dynamic attribute metric with attribute re-aggregation in configuration at runtime (#46353)
• (Contrib) receiver/filestats: Enable re-aggregation and set requirement levels for attributes. (#46355)
• (Contrib) 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.
• (Contrib) receiver/k8s_cluster: Emit entity references as part of metrics resources. (#41080)
• (Contrib) receiver/k8sobjects: Add kube_api_qps and kube_api_burst config 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/k8sevents via the shared internal/k8sconfig package.
  Default values match the client-go defaults: kube_api_qps=5, kube_api_burst=10.
• (Contrib) receiver/receiver_creator: Add support for profiling signal for receiver creator (#46930)
• (Contrib) receiver/splunkenterprise: Add custom search support to the Splunk Enterprise receiver (#47124)
• (Contrib) receiver/windows_event_log: Add discover_domain_controllers config flag to automatically discover and collect Security events from Active Directory domain controllers based on feature gate domainControllers.autodiscovery. (#44156, #44423)
  When discover_domain_controllers in config and domainControllers.autodiscovery feature gate is set true, the receiver queries LDAP Root DSE to
  discover the root domain path, enumerates all domain controllers in the Active Directory
  forest, and creates receiver for each domain controller.
  Falls back to the currently joined DC if the root DN cannot be determined.

🧰 Bug fixes 🧰

• (Core) exporter/debug: Guard against out-of-bounds profiles dictionary indices (#14803)
• (Core) pkg/otelcol: Fix missing default values in unredacted print-config command by introducing confmap.WithUnredacted MarshalOption. (#14750)
  Resolves an issue where the unredacted mode output omitted all default-valued options. By introducing a new MarshalOption to disable redaction directly at the confmap encoding level, the unredacted mode now preserves all component defaults natively without requiring post-processing.
• (Core) pkg/service: Headers on the internal telemetry OTLP exporter are now redacted when the configuration is marshaled (#14756)
• (Contrib) exporter/awss3: Use AWS SDK S3 types for StorageClass and ACL validation instead of hardcoded lists (#46825)
  The hardcoded list of valid S3 storage classes was missing GLACIER_IR, REDUCED_REDUNDANCY, and EXPRESS_ONEZONE.
  Replaced both StorageClass and ACL hardcoded validation maps with values from the AWS SDK s3types package
  to prevent this from going out of date again in the future.
• (Contrib) pkg/stanza: Fix severity parser to work with JSON parser with parse_ints: true (#47209)
• (Contrib) receiver/vcenter: Fixes a nil pointer dereference panic in recordVMStats when scraping metrics from VMs with missing performance counters (#46977)
