v0.55.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release (be sure to check the release notes here as well!).

🛑 Breaking changes 🛑

• datadogexporter: Remove Sanitize method from Config struct. (#8373)

• datadogexporter: (Under exporter.datadog.hostname.preview feature gate) Remove docker hostname detector (#11834)

• k8sclusterreceiver: The receiver.k8sclusterreceiver.reportCpuMetricsAsDouble feature gate has been removed (#10838)

  • If users were disabling this feature gate, they may have to update
    monitoring for a few Kubernetes cpu metrics. For more details see feature-gate-configurations.

• prometheusexporter: Automatically rename metrics with units to follow Prometheus naming convention (#8950)

🚩 Deprecations 🚩

• datadogexporter: Deprecate config package in favor of structs on the datadogexporter package. (#8373)

• k8sattributesprocessor: Announcing pod_association rules will be deprecated. Use pod_association.sources rules instead. This is in order to support metadata enrichment based on multiple attributes. (#4309)

• hostmetricsreceiver: Remove direction for network, paging and process metrics. The feature gates receiver.hostmetricsreceiver.emitMetricsWithoutDirectionAttribute and receiver.hostmetricsreceiver.emitMetricsWithDirectionAttribute can be used to control the transition (#11815)

  • system.network.dropped will become:
    • system.network.dropped.receive
    • system.network.dropped.transmit
  • system.network.errors will become:
    • system.network.errors.receive
    • system.network.errors.transmit
  • system.network.io will become:
    • system.network.io.receive
    • system.network.io.transmit
  • system.network.packets will become:
    • system.network.packets.receive
    • system.network.packets.transmit
  • system.paging.operations will become:
    • system.paging.operations.page_in
    • system.paging.operations.page_out
  • process.disk.io will become:
    • process.disk.io.read
    • process.disk.io.write

  See https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/hostmetricsreceiver#transition-from-metrics-with-direction-attribute for more details.

• logzioexporter: Announcing custom_endpoint, drain_interval, queue_capacity, queue_max_length configuration options will be deprecated in upcoming releases (#10821)
