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.

  • 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

  • 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.
