v0.124.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.124.0
and the opentelemetry-collector-contrib v0.124.1 releases where appropriate.

🛑 Breaking changes 🛑

• (Contrib) splunkenterprisereceiver: added new attributes to the receiver and modified config (#36330)
• (Contrib) extension/headerssetter: Change DefaultValue to use configopaque.String type. (#39127)
• (Contrib) splunkenterprisereceiver: disabled default metrics except for splunkHealth to ensure scrapes run on Splunk instance are opt-in (#39068)
• (Contrib) processor/transform: Fix Basic Config style to properly handle cache access. (#38926)
  The Transform processor now requires only one configuration style per processor's configuration, which means Advanced Config and Basic Config cannot be used together anymore.
• (Contrib) sqlserverreceiver: update the unit of db.lock_timeout attribute from millisecond to second. this attribute is part of the emitted query sample collection. (#39042)

🚩 Deprecations 🚩

• (Contrib) kafkaexporter: Deprecate auth::tls and introduce tls config (#37776)
• (Contrib) kafkametricsreceiver: Deprecate auth::tls and introduce tls config (#37776)
• (Contrib) kafkareceiver: Deprecate auth::tls and introduce tls config (#37776)
• (Contrib) kafkaexporter: deprecate topic and encoding, introduce signal-specific configuration (#35432)
• (Contrib) kafkareceiver: Add signal-specific topic and encoding config, deprecate existing topic/encoding config. (#32735)

💡 Enhancements 💡

• (Splunk) Update splunk-otel-javaagent to v2.15.0 (#6131)
• (Splunk) Update jmx-metric-gatherer to v1.46.0 (#6127)
• (Core) exporterhelper: Add support for bytes-based batching for profiles in the exporterhelper package. (#3262)
• (Core) otelcol: Enhance config validation using command to capture all validation errors that prevents the collector from starting. (#8721)
• (Core) exporterhelper: Link batcher context to all batched request's span contexts. (#12212, #8122)
• (Contrib) azuremonitorreceiver: Add subscription name resource attribute (#39029)
• (Contrib) azuremonitorreceiver: Allow to use metrics:getBatch API (Azure Monitor Metrics Data Plane) (#38651)
• (Contrib) kafkareceiver: Propagate Kafka headers as metadata (#39129)
  Allows the Kafka receiver to propagate Kafka headers as client.Info (metadata). Allowing downstream processors and exporters to access the values via the enriched context.
• (Contrib) kafkaexporter: Propagate metadata keys as headers (#39130)
  Adds a new config option specifying a list of metadata keys that should be propagated as Kafka message headers.
• (Contrib) receivercreator: Add kafkatopicsobserver to the receivercreator configuration (#37665)
• (Contrib) kafkaexporter: enable partitioning for all encodings (#39001, #38999)
  With the exception of Jaeger encodings which have their own partitioning logic,
  partitioning is now independent of the encoding used. This means that all encodings
  now support partitioning.
• (Contrib) signalfxexporter: Errors will now include the URL that it was trying to access (#39026)
• (Contrib) splunkhecexporter: Errors will now include the URL that it was trying to access (#39026)
• (Contrib) k8sattributesprocessor: Add option to configure automatic resource attributes - with annotation prefix (#37114)
  Implements Specify resource attributes using Kubernetes annotations.
  If you are using the file log receiver, you can now create the same resource attributes as traces (via OTLP) received
  from an application instrumented with the OpenTelemetry Operator -
  simply by adding the extract: { otel_annotations: true } configuration to the k8sattributesprocessor processor.
  See the documentation for more details.
• (Contrib) oracledbreceiver: Add support for parallel operations metrics (#39215)
  The following metrics are now available, all disabled by default:
  • 'DDL statements parallelized'
  • 'DML statements parallelized'
  • 'Parallel operations not downgraded'
  • 'Parallel operations downgraded to serial'
  • 'Parallel operations downgraded (1-25%)'
  • 'Parallel operations downgraded (25-50%)'
  • 'Parallel operations downgraded (50-75%)'
  • 'Parallel operations downgraded (75-99%)'
• (Contrib) k8sclusterreceiver: Add missing attributes to entities in experimental entity feature (#39038)
• (Contrib) pkg/stanza: Use buffer pool for the read buffers to limit allocations (#39373)
• (Contrib) postgresqlreceiver: add top query collection to help end user identify which query were executed in the postgresql database. (#39311)
• (Contrib) sqlserverreceiver: Allow full control of the "connection string" via the datasource configuration option (#39235)
• (Contrib) spanmetricsconnector: Initialise new calls_total metrics at 0 (#38537)
• (Contrib) pkg/stanza: Remove unnecessary slice allocation to track errors (even nil) (#39367)

🧰 Bug fixes 🧰

• (Core) confighttp: Ensure http authentication server failures are handled by the provided error handler (#12666)
• (Contrib) metricstransformprocessor: Fix aggregation of exponential histograms in metricstransform processor. (#39143)
  Fix a panic when the number of populated buckets varies, and fix summing of counts for the Zero bucket.
• (Contrib) pkg/ottl: Fix OTTL context inference order to prioritize the scope context over resource. (#39155)
• (Contrib) pkg/ottl: Fix so replace_all_patterns can replace keys using optional function (#32896)
  When using the replace_all_patterns with key and optional function on the replacement, the value was being replaced with the key. This change fixes that and now the key is replaced as intended.
• (Contrib) awss3exporter: Fixes an issue where the AWS S3 Exporter was forcing an ACL to be set, leading to unexpected behavior in S3 bucket permissions (#39346)
  Current behavior of the AWS S3 Exporter is to set the ACL to 'private' by default, this removes that behavior and sets no ACL if not specified.
• (Contrib) connector/spanmetrics: This change proposes moving the start timestamp (and last seen timestamp) from the resourceMetrics level to the individual metrics level. This will ensure that each metric has its own accurate start and last seen timestamps, regardless of its relationship to other spans. (#35994)
• (Contrib) receiver/kubeletstats: support user defined CA path for service account using the configtls option ca_file (#39291)
• (Contrib) splunkenterprisereceiver: Fixes otelcol_scraper_errored_metric_points metric, which was not incrementing properly (#38691)
• (Contrib) receivercreator: Fix automatic discovery of kafka endpoints (#39313).
