v0.73.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release, be sure to check the release notes there as well.

v0.73.0

🛑 Breaking changes 🛑

• googlecloudexporter: Disable retry helper by default in GCP and GMP exporter configs. (#19203)
• k8sattributesprocessor: Remove container.id as default metadata given possible ambiguity matching a container run to a container ID (#16432)
• pkg/ottl: Ability to reference matched capture groups in replace_pattern() and replace_all_patterns() (#18610)
  This change affects all processors that use OTTL (i.e. transformprocessor, routingprocessor, and filterprocessor).
  This is a breaking change in the rare scenario that the $ character is currently used in a replacement string.
  To output a literal $ in a replacement string it must now be escaped with an additional $.
• resourcedetectionprocessor: Bump OpenShift semconv version from 1.16.0 to 1.18.0. (#19168)
  Rename google openshift platform attribute from google_cloud_openshift to gcp_openshift.
• spanmetricsconnector: Drop Prometheus-specific metrics labels sanitization. (#18678)
  The spanmeterics connector is the OTel component, therefore, we would
  like to strip Prometheus-specific parts from it. Metric names and attributes
  conversion to Prometheus conventions should happen in Prometheus components,
  e.g. Prometheus Remote Write exporter.

🚀 New components 🚀

• filereceiver: Add basic file reading capabilities to file receiver. Second PR. (#14638)
  This component is not yet enabled.

💡 Enhancements 💡

• receiver/splunkhec: Adds sharedcomponent to Splunk HEC Receiver (#18734)

• resourcedetectionprocessor: Add support for detecting AWS Lambda resources. (#17584)

• awscloudwatchlogsexporter: Add the ability to export raw log to cloud watch (#18758)
  Add emf and raw log support for aws cloudwatch exporter.

• awsemfexporter: The AWS EMF exporter now supports the additional configuration flag retain_initial_value_of_delta_metric. With this flag active the first value of a metric is not discarded but instead sent to AWS. (#16218)

• processor/tailsampling: adds support for a BooleanAttribute PolicyType (#17545)
  enables use of boolean attrbiutes in defining tail sampling policies

• pkg/stanza: Add header_delimiter option to the csv_parser. (#18198)

• datadogexporter: Enable gzip compression for metric payloads submitted by native Datadog client (#17373)

• hostmetrics: Have the hostmetrics receiver file system scraper use more debug messages (#18236)
  Log a debug message instead of an error if the collector does not have the permissions to access a locked drive on the host. We do not want to log an error message on every poll for this case.

• exporter/prometheus: Produce exemplars for monotonic sum metrics (i.e. counters in Prometheus) when available (#18201)
  This could be a breaking change if you already have enabled OpenMetrics format for the Prometheus exporter and have enabled exemplar ingestion in your Prometheus scraper. To ensure names and types are generated correctly according to the OpenMetrics conventions, you should run your collector with --feature-gates=pkg.translator.prometheus.NormalizeName

• filelogreceiver: Adds ability to parse a file header and parse it as metadata to decorate log entries. (#18198)
  This feature must be activated with the filelog.allowHeaderMetadataParsing feature gate.

• receiver/purefareceiver: Ensure a clear visualization for hosts scraper from Pure Storage FlashArray API (#14886)

• k8sattributesprocessor: e2e test support log data (#18392)

• k8sattributesprocessor: k8sattributesprocessor e2e tests support metric data type. (#18391)

• k8sattributesprocessor: Default container.id to latest instance unless k8s.container.restart_count is specified (#16432)

• mdatagen: Turn on the ability to enable/disable resource attributes by embedding MetricsSettings and ResourceAttributesSettings into all scraping receivers as MetricsBuilderConfig (#16373)
  Currently, the only way to add configurative functionality to mdatagen is by using a bunch of WithResourceAttributesSettings options to the constructor.
  This PR changes the first argument to the NewMetricsBuilder constructor to be of type MetricsBuilderConfig,
  which is a new class that wraps both MetricsSettings and ResourceAttributesSettings, and may be (hopefully) easily extended with more
  configuration in the future.

• pkg/ottl: Add Eval function to Statements (#18915)

• Process Metrics for Mac: Enabling process metrics to be collected for Mac in the hostmetrics receiver (#17863)

• prometheusremotewriteexporter: Export _created metric for Summary, Histogram and Monotonic Sum metric points if StartTimeUnixNano is set. (#17412, #12426)

  If the _created metric was present in the Histogram, Summary or Counter
  metric family, only then its values is used to set StartTimeUnixNano on the
  relevant OTLP metric and dropped afterwards. Otherwise, it is converted to the
  monotonic OTLP Sum metric.
  This behaviour is disabled by default. Use the receiver.prometheusreceiver.UseCreatedMetric
  to enable it.

  Fixed a potential panic due to a syscall indicating a that the event buffer should resize to 0. The next used of that resized buffer would result in an index out of bounds panic.

  Also, added a safety check for buffer resize cases that if the syscall indicates it needs the buffer size to be 0, an error will be returned.
