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)
    The attribute is used to set the proper refType when translating back from OTEL to Jager.

    In the case of a span with multiple parents, which Jaeger supports, all the refType are properly translated.

  • apachereceiver: add port resource attribute (#14791)

  • apachereceiver: Extract server name as resource attribute (#14791)
    The feature is enabled through a feature gate and will be enabled by default in v0.65.

  • mysqlreceiver: add more mysql metrics (#14138)

    • Add mysql.connection.errors metric (#14723)
    • Add mysql.mysqlx_connections metric (#14727)
    • Add mysql.joins metric (#14728)
    • Add mysql.table_open_cache metric (#14737)
    • Add mysql queries (all, client and slow) count metrics (#14738)
    • Add metrics based on events_statements_summary_by_digest table (#14770)
    • Add mysql.client.network.io metric (#14744)

  • elasticsearchreceiver: add translog metrics on index level (#14635)

  • hostmetricsreceiver: Add new process metrics (#12482)
    Add process.context_switches and process.open_file_descriptors as process metrics. They are disabled by default.

  • metricstransformprocessor: Add support for scaling histogram metrics (#15690)

  • datadogexporter: Use minimum and maximum fields from delta OTLP Histograms and OTLP ExponentialHistograms when available. (#16048)

  • pkg/ottl: Add ConvertCase OTTL function with lower, upper, camel and snake case options. (#15379, #16070, #16083)

  • pkg/ottl: Add parent_span_id.string accessor. (#16041)

  • pkg/ottl: Add new Span Event context to allow for efficient transformation of Span Event telemetry. (#14907)

  • pkg/stanza, filelog, journald, syslog, tcplog, udplog, windowseventlog, logstransform: This component does not mutate data, but can be useful as a generic node in complex pipelines. (#15706)

  • pkg/stanza: improve performance (#16028)

  • signalfxexporter: Allow 2 additional metrics to be included when exporting to SignalFx, k8s.container.cpu_request and k8s.container.memory_request. (#16009)

  • hostmetricsreceiver: Added root_path config option, allowing the user to specify where the host filesystem is. (#5879, #16026)

  • snmpreceiver: adds integration tests for SNMP metric receiver (#13409)

  • snmpreceiver: adds scraper for SNMP metric receiver (#13409)

  • spanmetricsprocessor: Improve spanmetricsprocessor performance, reuse buffer to calculate key (#16033)

  • global: Update gopsutil to 3.22.10 to return Windows partitions, regardless of errors (#14315)

🧰 Bug fixes 🧰

  • clickhouseexporter: remove unnecessary function in trace table creation SQL (#15679)

  • elasticsearchexporter: Fixed nil panic error when setting custom headers in elasticsearch exporter (#16017)

  • elasticsearchreceiver: emit missing data points related to segments, aggregated by primary shards (#14635)

  • zipkinreceiver: Fix invalid timestamps when using Zipkin V1 receiver (#15720)

  • kubeletstatsreceiver: return an error if metadata containerID is empty and log a warning message (#16061)
    The kubelet apiserver /pod metadata endpoint might not have the containerID set for newly created containers.
    Mark these datapoints as failed and don't process them. The issue should be resolved on the nexy poll.

  • jaegertranslator: For HTTP status codes in the 4xx range span status MUST be left unset in case of SpanKind.SERVER and MUST be set to Error in case of SpanKind.CLIENT. (#8273)

  • mezmoexporter: Fix usage of HTTP client to honor settings (#15246)
    This change fixes mezmoexporter's usage of the user supplied HTTP client
    settings. Previously, the settings were ignored for every request.

  • vcenterreceiver: Print the correct error message if VM fetch fails. (#15682)

  • vcenterreceiver: Fix x509 with TLS.InsecureSkipVerify setting (#15701)

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
        • 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)

  • 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.
