v0.61.0

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

🛑 Breaking changes 🛑

  • dockerstatsreceiver: For V2 scraper implementation, change the defaults from emitting everything to a sensible set of defaults. (#9794, #14093)
    This is only breaking if you have explicitly enabled the featuregate receiver.dockerstats.useScraperV2.
  • dockerstatsreceiver: Change 'stats' config key to 'metrics'. (#9794, #14184)
    Note: this is only breaking for those who have explicitly enabled the featuregate receiver.dockerstatsd.useScraperV2.

v0.59.0

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

🛑 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)

    • 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

  • 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)

  • ``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)

  • dockerstatsreceiver: Change relevant memory metrics from gauges to sums, so they are aligned with spec recommendations and can be aggregated. (#9794)

  • pkg/stanza/csv_parser: Add ignore_quotes option that ignores all quoting in fields if true. (#13656)

  • pkg/telemetryquerylanguage: Add TQL mappings for InstrumentationScope.attributes (#13639)

  • coreinternal: Move test utilities out of testbed into coreinternal, allow use of these lightweight helpers from other modules. (#5742)

    Adds the following metrics:

    • postgresql.bgwriter.buffers.allocated
    • postgresql.bgwriter.buffers.writes
    • postgresql.bgwriter.checkpoint.count
    • postgresql.bgwriter.duration
