Release Notes

open-telemetry/opentelemetry-collector (go.opentelemetry.io/collector/pdata)

v1.38.0

🛑 Breaking changes 🛑

• componentstatus: Change the signature of the componentstatus.NewEvent to accept multiple options. (#​13210)
  Changes the signature of the component.NewEvent to accept multiple EventBuilderOption,
  like the new WithAttributes constructor.

🚩 Deprecations 🚩

• service: move service.noopTraceProvider feature gate to deprecated stage (#​13492)
  The functionality of the feature gate is available via configuration with the following telemetry settings:

  service:
    telemetry:
      traces:
        level: none
  

• mdatagen: Remove the deletion of generated_component_telemetry_test.go. (#​12067)
  This file used to be generated by mdatagen. Starting with 0.122.0, the code deletes that file.
  It is no longer necessary to delete the file, as code has had time to upgrade to mdatagen and delete the file.

• service: The telemetry.disableHighCardinalityMetrics feature gate is deprecated (#​13537)
  The feature gate is now deprecated since metric views can be configured.
  The feature gate will be removed in v0.134.0.

  The metric attributes removed by this feature gate are no longer emitted
  by the Collector by default, but if needed, you can achieve the same
  functionality by configuring the following metric views:

  service:
    telemetry:
      metrics:
        level: detailed
        views:
          - selector:
              meter_name: "go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc"
            stream:
              attribute_keys:
                excluded: ["net.sock.peer.addr", "net.sock.peer.port", "net.sock.peer.name"]
          - selector:
              meter_name: "go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp"
            stream:
              attribute_keys:
                excluded: ["net.host.name", "net.host.port"]

  Note that this requires setting service::telemetry::metrics::level: detailed.
  If you have a strong use case for using views in combination with a different
  level, please show your interesthttps://github.com/open-telemetry/opentelemetry-collector/issues/10769/10769.

v1.36.1

🧰 Bug fixes 🧰

• service: Fixes bug where internal metrics are emitted with an unexpected suffix in their names when users configure service::telemetry::metrics::readers with Prometheus. (#​13449)
  See more details ohttps://github.com/open-telemetry/opentelemetry-go/issues/703939

v1.36.0

❗ Known Issues ❗

• Due to a bug in the prometheus exporter, if you are configuring a prometheus exporter, the collector's internal metrics will be emitted with an unexpected suffix in its name. For example, the metric otelcol_exporter_sent_spans__spans__total instead of otelcol_exporter_sent_spans_total. The workaround is to manually configure without_units: true in your prometheus exporter config

  service:
    telemetry:
      metrics:
        readers:
          - pull:
              exporter:
                prometheus:
                  host: 0.0.0.0
                  port: 8888
                  without_units: true

  If you are using the collector's default Prometheus exporter for exporting internal metrics you are unaffected.

🛑 Breaking changes 🛑

• exporter/otlp: Remove deprecated batcher config from OTLP, use queuebatch (#​13339)

💡 Enhancements 💡

• exporterhelper: Enable items and bytes sizers for persistent queue (#​12881)
• exporterhelper: Refactor persistent storage size backup to always record it. (#​12890)
• exporterhelper: Add support to configure a different Sizer for the batcher than the queue (#​13313)
• yaml: Replaced sigs.k8s.io/yaml with go.yaml.in/yaml for improved support and long-term maintainability. (#​13308)

🧰 Bug fixes 🧰

• exporterhelper: Fix exporter.PersistRequestContext feature gate (#​13342)

• exporterhelper: Preserve all metrics metadata when batch splitting. (#​13236)
  Previously, when large batches of metrics were processed, the splitting logic in metric_batch.go could
  cause the name field of some metrics to disappear. This fix ensures that all metric fields are
  properly preserved when metricRequest objects are split.

• service: Default internal metrics config now enables otel_scope_ labels (#​12939, #​13344)
  By default, the Collector exports its internal metrics using a Prometheus
  exporter from the opentelemetry-go repository. With this change, the Collector
  no longer sets "without_scope_info" to true in its configuration.

  This means that all exported metrics will have otel_scope_name,
  otel_scope_schema_url, and otel_scope_version labels corresponding to the
  instrumentation scope metadata for that metric.

  This notably prevents an error when multiple metrics are only distinguished
  by their instrumentation scopes and end up aliased during export.

  If this is not desired behavior, a Prometheus exporter can be explicitly
  configured with this option enabled.

v1.35.0

🛑 Breaking changes 🛑

• exporterhelper: Remove deprecated sending_queue::blocking options, use sending_queue::block_on_overflow. (#​13211)

💡 Enhancements 💡

• mdatagen: Taught mdatagen to print the go list stderr output on failures, and to run go list where the metadata file is. (#​13205)

• service: Support setting sampler and limits under service::telemetry::traces (#​13201)
  This allows users to enable sampling and set span limits on internal Collector traces using the
  OpenTelemetry SDK declarative configuration.

• pdata/pprofile: Add new helper methods FromLocationIndices and PutLocation to read and modify the content of locations. (#​13150)

• exporterhelper: Preserve request span context and client information in the persistent queue. (#​11740, #​13220, #​13232)
  It allows internal collector spans and client information to propagate through the persistent queue used by
  the exporters. The same way as it's done for the in-memory queue.
  Currently, it is behind the exporter.PersistRequestContext feature gate, which can be enabled by adding
  --feature-gates=exporter.PersistRequestContext to the collector command line. An exporter buffer stored by
  a previous version of the collector (or by a collector with the feature gate disabled) can be read by a newer
  collector with the feature enabled. However, the reverse is not supported: a buffer stored by a newer collector with
  the feature enabled cannot be read by an older collector (or by a collector with the feature gate disabled).

🧰 Bug fixes 🧰

• pdata: Fix copying of optional fields when the source is unset. (#​13268)
• service: Only allocate one set of internal log sampling counters (#​13014)
  The case where logs are only exported to stdout was fixed in v0.126.0;
  this new fix also covers the case where logs are exported through OTLP.

• service: Use configured loggers to log errors as soon as it is available (#​13081)

• service: Remove stabilized featuregate useOtelWithSDKConfigurationForInternalTelemetry (#​13152)

🧰 Bug fixes 🧰

• telemetry: Add generated resource attributes to the printed log messages. (#​13110)
  If service.name, service.version, or service.instance.id are not specified in the config, they will be generated automatically.
  This change ensures that these attributes are also included in the printed log messages.

  • otelcol.connector.consumed.items
  • otelcol.connector.produced.items
  • otelcol.exporter.consumed.items

• tls: Add trusted platform module (TPM) support to TLS authentication. (#​12801)
  Now the TLS allows the use of TPM for loading private keys (e.g. in TSS2 format).

🧰 Bug fixes 🧰

• exporterhelper: Add validation error for batch config if min_size is greater than queue_size. (#​12948)

• telemetry: Allocate less memory per component when OTLP exporting of logs is disabled (#​13014)

• confmap: Use reflect.DeepEqual to avoid panic when confmap.enableMergeAppendOption feature gate is enabled. (#​12932)

• internal telemetry: Add resource attributes from telemetry.resource to the logger (#​12582)
  Resource attributes from telemetry.resource were not added to the internal
  console logs.

  Now, they are added to the logger as part of the "resource" field.

• confighttp and configcompression: Fix handling of snappy content-encoding in a backwards-compatible way (#​10584, #​12825)
  The collector used the Snappy compression type of "framed" to handle the HTTP
  content-encoding "snappy". However, this encoding is typically used to indicate
  the "block" compression variant of "snappy". This change allows the collector to:

  • When receiving a request with encoding 'snappy', the server endpoints will peek
    at the first bytes of the payload to determine if it is "framed" or "block" snappy,
    and will decompress accordingly. This is a backwards-compatible change.

  If the feature-gate "confighttp.framedSnappy" is enabled, you'll see new behavior for both client and server:

  • Client compression type "snappy" will now compress to the "block" variant of snappy
    instead of "framed". Client compression type "x-snappy-framed" will now compress to the "framed" variant of snappy.
  • Servers will accept both "snappy" and "x-snappy-framed" as valid content-encodings.

• tlsconfig: Disable TPM tests on MacOS/Darwin (#​12964)

v1.31.0

🛑 Breaking changes 🛑

• service: Lowercase values for 'otelcol.component.kind' attributes. (#​12865)

• service: Restrict the telemetry.newPipelineTelemetry feature gate to metrics. (#​12856, #​12933)
  The "off" state of this feature gate introduced a regression, where the Collector's internal logs were missing component attributes. See issue #​12870 for more details on this bug.

  On the other hand, the "on" state introduced an issue with the Collector's default internal metrics, because the Prometheus exporter does not currently support instrumentation scope attributes.

  To solve both of these issues, this change turns on the new scope attributes for logs and traces by default regardless of the feature gate.
  However, the new scope attributes for metrics stay locked behind the feature gate, and will remain off by default until the Prometheus exporter is updated to support scope attributes.

  Please understand that enabling the telemetry.newPipelineTelemetry feature gate may break the export of Collector metrics through, depending on your configuration.
  Having a batch processor in multiple pipelines is a known trigger for this.

  This comes with a breaking change, where internal logs exported through OTLP will now use instrumentation scope attributes to identify the source component instead of log attributes.
  This does not affect the Collector's stderr output. See the changelog for v0.123.0 for a more detailed description of the gate's effects.

• mdatagen: Add time and plog package imports (#​12907)
• confmap: Maintain nil values when marshaling or unmarshaling nil slices (#​11882)
  Previously, nil slices were converted to empty lists, which are semantically different
  than a nil slice. This change makes this conversion more consistent when encoding
  or decoding config, and these values are now maintained.

v1.30.0

💡 Enhancements 💡

• exporterhelper: Add support for bytes-based batching for profiles in the exporterhelper package. (#​3262)
• otelcol: Enhance config validation using command to capture all validation errors that prevents the collector from starting. (#​8721)
• exporterhelper: Link batcher context to all batched request's span contexts. (#​12212, #​8122)

🧰 Bug fixes 🧰

• confighttp: Ensure http authentication server failures are handled by the provided error handler (#​12666)

v1.29.0

❗ Known Issues ❗

• This version increases memory usage by ~0.5 MB per component in the pipelines because a separate Zap Core logger is
  initialized for each component. The issue is partially fixed in v0.126.0 for users who write logs to stdout, but do
  not export logs via OTLP. https://github.com/open-telemetry/opentelemetry-collector/issues/130143014 for more details.

🛑 Breaking changes 🛑

• service/telemetry: Mark telemetry.disableAddressFieldForInternalTelemetry as beta, usage of deprecated service::telemetry::address are ignored (#​25115)
  To restore the previous behavior disable telemetry.disableAddressFieldForInternalTelemetry feature gate.
• exporterbatch: Remove deprecated fields min_size_items and max_size_items from batch config. (#​12684)

🚩 Deprecations 🚩

• otlpexporter: Mark BatcherConfig as deprecated, use sending_queue::batch instead (#​12726)
• exporterhelper: Deprecate blocking in favor of block_on_overflow. (#​12710)
• exporterhelper: Deprecate configuring exporter batching separately. Use sending_queue::batch instead. (#​12772)
  Moving the batching configuration to sending_queue::batch requires setting sending_queue::sizer to items
  which means that sending_queue::queue_size needs to be also increased by the average batch size number (roughly
  x5000 for the default batching configuration).
  See https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/exporterhelper#configuration

💡 Enhancements 💡

• exporterhelper: Add support to configure batching in the sending queue. (#​12746)

• exporterhelper: Add support for wait_for_result, remove disabled_queue (#​12742)
  This has a side effect for users of the experimental BatchConfig with the queue disabled, since not this is | uses only NumCPU() consumers.

• exporterhelper: Allow exporter memory queue to use different type of sizers. (#​12708)

• service: Add "telemetry.newPipelineTelemetry" feature gate to inject component-identifying attributes in internal telemetry (#​12217)
  With the feature gate enabled, all internal telemetry (metrics/traces/logs) will include some of
  the following instrumentation scope attributes:

  • otelcol.component.kind
  • otelcol.component.id
  • otelcol.pipeline.id
  • otelcol.signal
  • otelcol.signal.output

  These attributes are defined in the Pipeline Component Telemetry RFC,
  and identify the component instance from which the telemetry originates.
  They are added automatically without changes to component code.

  These attributes were already included in internal logs as regular log attributes, starting from
  v0.120.0. For consistency with other signals, they have been switched to scope attributes (with
  the exception of logs emitted to standard output), and are now enabled by the feature gate.

  Please make sure that the exporter / backend endpoint you use has support for instrumentation
  scope attributes before using this feature. If the internal telemetry is exported to another
  Collector, a transform processor could be used to turn them into other kinds of attributes if
  necessary.

• exporterhelper: Enable support to do batching using bytes sizer (#​12751)

• service: Add config key to set metric views used for internal telemetry (#​10769)
  The service::telemetry::metrics::views config key can now be used to explicitly set the list of
  metric views used for internal telemetry, mirroring meter_provider::views in the SDK config.
  This can be used to disable specific internal metrics, among other uses.

  This key will cause an error if used alongside other features which would normally implicitly create views, such as:

  • not setting service::telemetry::metrics::level to detailed;
  • enabling the telemetry.disableHighCardinalityMetrics feature flag.

• otlphttpexporter: Fix parsing logic for Retry-After in OTLP http protocol. (#​12366)
  The value of Retry-After field can be either an HTTP-date or delay-seconds and the current logic only parsed delay-seconds.
• cmd/builder: Ensure unique aliases for modules with same suffix (#​12201)

v1.25.0

🛑 Breaking changes 🛑

• exporterhelper: Rename exporter span signal specific attributes (e.g. "sent_spans" / "send_failed_span") to "items.sent" / "items.failed". (#​12165)

• cmd/mdatagen: Remove dead field telemetry::level (#​12144)

• exporterhelper: Change exporter ID to be a Span level attribute instead on each event. (#​12164)
  This does not have an impact on the level of information emitted, but on the structure of the Span.

• cmd/mdatagen: Remove level field from metrics definition (#​12145)
  This mechanism will be added back once a new views mechanism is implemented.

• service: Value for telemetry exporter otlp.protocol updated from grpc/protobuf to grpc. (#​12337)

• service: internal metrics exported over Prometheus may differ from previous versions. (#​11611)

  Users who do not customize the Prometheus reader should not be impacted. The change to update the internal telemetry to use otel-go config can cause unexpected behaviour
  for end users. This change is caused by the default values in config being different from what the Collector has used in previous versions. The
  following changes can occur when users configure their service::telemetry::metrics::readers:

  • the metric name will append a _total suffix if without_type_suffix is not configured. Set without_type_suffix to true to disable this.
  • units will be appended to metric name if without_units is not configured. Set without_units to true to disable this.
  • a target_info metric will be emitted if without_scope_info is not configured. Set without_scope_info to true to disable this.

💡 Enhancements 💡

• configtls: Allow users to mention their preferred curve types for ECDHE handshake (#​12174)
• service: remove custom code and instead use config package to instantiate meter provider. (#​11611)
• otelcol: Adds support for listing config providers in components command's output (#​11570)
• general: Reduce memory allocations when loading configuration and parsing component names (#​11964)

🧰 Bug fixes 🧰

• exporterhelper: Fix bug that the exporter with new batcher may have been marked as non mutation. (#​12239)
  Only affects users that manually turned on exporter.UsePullingBasedExporterQueueBatcher featuregate.

• service: Preserve URL normalization logic that was present before. (#​12254)

• confighttp: confighttp.ToServer now sets ErrorLog with a default logger backed by Zap (#​11820)

  This change ensures that the http.Server's ErrorLog is correctly set using Zap's logger at the error level, addressing the issue of error logs being printed using a different logger.

• exporterhelper: Fix context propagation for DisabledBatcher (#​12231)

• mdatagen: apply fieldalignment to generated code (#​12125)

• mdatagen: Fix bug where Histograms were marked as not supporting temporal aggregation (#​12168)

• exporterhelper: Fix MergeSplit issue that ignores the initial message size. (#​12257)

• service: Include validation errors from telemetry.Config when validating the service config (#​12100)
  Previously validation errors were only printed to the console

• service-telemetry: pass the missing async error channel into service telemetry settings (#​11417)

v1.24.0

💡 Enhancements 💡

• exporterhelper: Add blocking option to control queue behavior when full (#​12090)
• debugexporter: Add EventName to debug exporter for Logs. EventName was added as top-level field in the LogRecord from 1.5.0 of proto definition. (#​11966)
• confighttp: Added support for configuring compression levels. (#​10467)
  A new configuration option called CompressionParams has been added to confighttp. | This allows users to configure the compression levels for the confighttp client.
• exporterhelper: Change the memory queue implementation to not pre-allocate capacity objects. (#​12070)
  This change improves memory usage of the collector under low utilization and is a prerequisite for supporting different other size limitations (number of items, bytes).

🧰 Bug fixes 🧰

• mdatagen: apply fieldalignment to generated code (#​12121)
• otelcoltest: Set DefaultScheme to env in the test ConfigProvider to replicate the default provider used by the Collector. (#​12066)

v1.23.0

🛑 Breaking changes 🛑

• otelcol: Remove warnings when 0.0.0.0 is used (#​11713, #​8510)

🧰 Bug fixes 🧰

• internal/sharedcomponent: Fixed bug where sharedcomponent would use too much memory remembering all the previously reported statuses (#​11826)

v1.22.0

🛑 Breaking changes 🛑

• pdata/pprofile: Remove deprecated Profile.EndTime and Profile.SetEndTime methods. (#​11796)

💡 Enhancements 💡

• xconfighttp: Add WithOtelHTTPOptions to experimental module xconfighttp (#​11770)

🧰 Bug fixes 🧰

• exporterhelper: Fix memory leak at exporter shutdown (#​11401)
