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

馃洃 Breaking changes 馃洃

  • 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)

    • kubeletstats metrics:
      • k8s.node.network.io will become:
        • k8s.node.network.io.transmit
        • k8s.node.network.io.receive
      • k8s.node.network.errors will become:
        • k8s.node.network.errors.transmit
        • k8s.node.network.errors.receive

  • 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.

  • ``filelog, journald`, `otlpjsonfile`, `syslog`, `tcplog`, `udplog`, `windowseventlog` receivers`: Remove `helper.Duration` struct. Configured time values no longer have a default unit of `s` (#13439)

  • pkg/stanza: Remove HostIdentifier, HostIdentifierConfig and associated functions (#13396)

  • ``filelog, journald`, `syslog`, `tcplog`, `udplog`, and `windowseventlog` receivers`: Fix a bug where original severity text was not preserved. (#13263)

  • pkg/stanza: Update function and struct names in keyvalue parser (#13418)

  • cmd/mdatagen: Remove old metadata generator (#13374)
