Version v0.65.0

Release v0.64.0

Images and binaries here: https://github.com/open-telemetry/opentelemetry-collector-releases/releases/tag/v0.64.0

🛑 Breaking changes 🛑

• pkg/stanza, filelog, journald, syslog, tcplog, udplog, windowseventlog, logstransform: Remove ability to configure converter. (#15696)
  The design of the converter is opaque and its behavior may change in the future.
  Because of this, the converter settings are deemed unstable. The actual behavior of the
  converter remains unchanged, but will always use the former default values.

• exporter/googlemanagedprometheusexporter: Moved ClientConfig under MetricConfig, and added an option to change the default metric name prefix for advanced use cases. (#10543)

• pkg/ottl: Update ExprFunc, Set, and Get to all return errors. (#15649)

• pkg/ottl: Change Statement to use Expr[K] and BoolExpr[K] and for Statement.Execute to require context.Context. (#15709)

• tanzuobservabilityexporter: Add a new metric exporter config(app_tags_excluded) to exclude application resource attrs(application, service.name, cluster, shard) from the metric tags. Rename the config resource_attributes to resource_attrs_included. Build in-house logic in the tanzuobservability exporter and remove the usage of resourcetotelemetry. (#14733)

🚩 Deprecations 🚩

• hostmetricsreceiver: Introduce renamed process memory metrics (#14327)
  This starts the process of phasing out incorrect metric names:

  • process.memory.physical_usage
  • process.memory.virtual_usage

  and replacing them with the names adhering to the semantic conventions:

  • process.memory.usage
  • process.memory.virtual

  At this stage, the new metrics are added, but they are disabled by default.
  See the "Deprecations" section of the Host Metrics receiver's README for details.

💡 Enhancements 💡

• awsemfexporter: Added a log_retention field to the config to specify log retention policy for a Cloudwatch Log Group (#15678)

• translator/jaeger: Add refType as attribute to link when translating Jaeger span references to OTEL. (#14465)

🛑 Breaking changes 🛑

• elasticsearchreceiver: Remove direction for metrics. The feature gate: receiver.elasticsearchreceiver.emitMetricsWithoutDirectionAttribute can be set to apply the following (#13258) (#12189)

  • elasticsearch metrics:
    • elasticsearch.node.cluster.io will become:
      • elasticsearch.node.cluster.io.received
      • elasticsearch.node.cluster.io.sent

• kubeletstatsreceiver: Remove direction for metrics. The feature gate: receiver.kubeletstatsreceiver.emitMetricsWithoutDirectionAttribute can be set to apply the following (#12588) (#12164)

      • k8s.node.network.errors.transmit

• processor/metricstransform: Remove processor.metricstransformprocessor.UseOTLPDataModel feature flag. OpenCensus-based implementation is not available anymore.
  (#13405)

• exporter/mezmoexporter: This change removes the hardcoded "otel" hostname that was embedded
  in outgoing logs data.
  (#13410)
  It is replaced by:

  1. Sending to a new collector endpoint that does not require the
     hostname parameter.

  2. Recognizing the "host.name" resource attribute and using that
     value to fill in log metadata recognized upstream.

  This is a breaking change, and as such will generate a startup
  error if the exporter is configured to send to an endpoint that
  does not support this feature.
