Release Notes

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

v1.56.0

v1.55.0

🛑 Breaking changes 🛑

• pkg/service: Remove service_name, service_instance_id, and service_version as constant labels on every internal metric datapoint. These attributes are already present in target_info and were being duplicated on each series for OpenCensus backwards compatibility. (#​14811)
  Previously, the collector stamped every internal metric series (e.g. otelcol_process_runtime_heap_alloc_bytes)
  with service_name, service_instance_id, and service_version labels to match the old OpenCensus behavior.
  These attributes are now only present in the target_info metric, which is the correct Prometheus/OTel convention.
  Users who filter or group by these labels on individual metrics will need to update their queries to use
  target_info joins instead.

💡 Enhancements 💡

• all: Move aix/ppc64 to tier 3 support (#​13380)

• all: Upgrade the profiles stability status to alpha (#​14817)
  The following components have their profiles status upgraded from development to alpha:

  • pdata/pprofile
  • connector/forward
  • exporter/debug
  • receiver/nop
  • exporter/nop
  • exporter/otlp_grpc
  • exporter/otlp_http

• cmd/mdatagen: Add semconv reference for attributes (#​13297)

🧰 Bug fixes 🧰

• cmd/mdatagen: Fix entity code generation so extra_attributes are emitted as resource attributes instead of entity descriptive attributes. (#​14778)

v1.54.0

❗ Known Issues ❗

• service: The collector's internal Prometheus metrics endpoint (:8888) now emits OTel service labels with underscore
  names (service_name, service_instance_id, service_version) instead of dot-notation names (service.name,
  service.instance.id, service.version). Users scraping this endpoint with the Prometheus receiver will see these renamed
  labels in resource and datapoint attributes. As a workaround, add the following metric_relabel_configs to your scrape
  config in prometheus receiver:

  metric_relabel_configs:
    - source_labels: [service_name]
      target_label: service.name
    - source_labels: [service_instance_id]
      target_label: service.instance.id
    - source_labels: [service_version]
      target_label: service.version
    - regex: service_name|service_instance_id|service_version
      action: labeldrop

  See #​14814 for details and updates.

🛑 Breaking changes 🛑

• all: Change metric units to be singular to match OTel specification, e.g. {requests} -> {request} (#​14753)

💡 Enhancements 💡

• cmd/mdatagen: Add deprecated_type field to allow specifying an alias for component types. (#​14718)
• cmd/mdatagen: Generate entity-scoped MetricsBuilder API that enforces entity-metric associations at compile time (#​14659)
• cmd/mdatagen: Skip generating reaggregation config options for metrics that have no aggregatable attributes. (#​14689)
• pkg/service: The internal status reporter no longer drops repeated Ok and RecoverableError statuses (#​14282)
  Status events can now carry metadata and there's value in allowing them to be emitted despite the status value itself
  not changing.

🧰 Bug fixes 🧰

• cmd/builder: Add .exe to output binary names when building for Windows targets. (#​12591)

• exporter/debug: Add printing of metric metadata in detailed verbosity. (#​14667)

• exporter/otlp_grpc: Prevent nil pointer panic when push methods are called before the OTLP exporter initializes its gRPC clients. (#​14663)
  When the sending queue and retry are disabled, calling ConsumeTraces,
  ConsumeMetrics, ConsumeLogs, or ConsumeProfiles before the OTLP exporter
  initializes its gRPC clients could cause a nil pointer dereference panic.
  The push methods now return an error instead of panicking.

• exporter/otlp_http: Show the actual destination URL in error messages when request URL is modified by middleware. (#​14673)
  Unwraps the *url.Error returned by http.Client.Do() to prevent misleading error logs when a middleware extension dynamically updates the endpoint.

• pdata/pprofile: Switch the dictionary of dictionary tables entries only once when merging profiles (#​14709)
  For dictionary table data, we used to switch their dictionaries when doing
  the switch for the data that uses them.
  However, when an entry is associated with multiple other data (several
  samples can use the same stack), we would have been switching the
  dictionaries of the entry multiple times.

  We now switch dictionaries for dictionary table data only once, before
  switching the resource profiles.

v1.53.0

💡 Enhancements 💡

• exporter/debug: Output bucket counts for exponential histogram data points in normal verbosity. (#​10463)
• pkg/exporterhelper: Add metadata_keys configuration to sending_queue.batch.partition to partition batches by client metadata (#​14139)
  The metadata_keys configuration option is now available in the sending_queue.batch.partition section for all exporters.
  When specified, batches are partitioned based on the values of the listed metadata keys, allowing separate batching per metadata partition. This feature
  is automatically configured when using exporterhelper.WithQueue().

🧰 Bug fixes 🧰

• cmd/builder: Fix duplicate error output when CLI command execution fails in the builder tool. (#​14436)

• cmd/mdatagen: Fix duplicate error output when CLI command execution fails in the mdatagen tool. (#​14436)

• cmd/mdatagen: Fix semconv URL validation for metrics with underscores in their names (#​14583)
  Metrics like system.disk.io_time now correctly validate against semantic convention URLs containing underscores in the anchor tag.

• extension/memory_limiter: Use ChainUnaryInterceptor instead of UnaryInterceptor to allow multiple interceptors. (#​14634)
  If multiple extensions that use the UnaryInterceptor are set the binary panics at start time.

• extension/memory_limiter: Add support for streaming services. (#​14634)

• pkg/config/configmiddleware: Add context.Context to HTTP middleware interface constructors. (#​14523)
  This is a breaking API change for components that implement or use extensionmiddleware.

• pkg/confmap: Fix another issue where configs could fail to decode when using interpolated values in string fields. (#​14034)
  For example, a resource attribute can be set via an environment variable to a string that is parseable as a number, e.g. 1234.

  (A similar bug was fixed in a previous release: that one was triggered when the field was nested in a struct,
  whereas this one is triggered when the field internally has type "pointer to string" rather than "string".)

• pkg/otelcol: The featuregate subcommand now rejects extra positional arguments instead of silently ignoring them. (#​14554)

• pkg/queuebatch: Fix data race in partition_batcher where resetTimer() was called outside mutex, causing concurrent timer.Reset() calls and unpredictable batch flush timing under load. (#​14491)

• pkg/scraperhelper: Log scrapers now emit log-appropriate receiver telemetry (#​14654)
  Log scrapers previously emitted the same receiver telemetry as metric scrapers,
  such as the otelcol_receiver_accepted_metric_points metric (instead of otelcol_receiver_accepted_log_records),
  or spans named receiver/myreceiver/MetricsReceived (instead of receiver/myreceiver/LogsReceived).

  This did not affect scraper-specific spans and metrics.

• processor/batch: Fixes a bug where the batch processor would not copy SchemaUrl metadata from resource and scope containers during partial batch splits. (#​12279, #​14620)

v1.52.0

v1.51.0

💡 Enhancements 💡

• pkg/scraperhelper: ScraperID has been added to the logs for metrics, logs, and profiles (#​14461)

🧰 Bug fixes 🧰

• exporter/otlp_grpc: Fix the OTLP exporter balancer to use round_robin by default, as intended. (#​14090)

• pkg/config/configoptional: Fix Unmarshal methods not being called when config is wrapped inside Optional (#​14500)
  This bug notably manifested in the fact that the sending_queue::batch::sizer config for exporters
  stopped defaulting to sending_queue::sizer, which sometimes caused the wrong units to be used
  when configuring sending_queue::batch::min_size and max_size.

  As part of the fix, xconfmap exposes a new xconfmap.WithForceUnmarshaler option, to be used in the Unmarshal methods
  of wrapper types like configoptional.Optional to make sure the Unmarshal method of the inner type is called.

  The default behavior remains that calling conf.Unmarshal on the confmap.Conf passed as argument to an Unmarshal
  method will skip any top-level Unmarshal methods to avoid infinite recursion in standard use cases.

• pkg/confmap: Fix an issue where configs could fail to decode when using interpolated values in string fields. (#​14413)
  For example, a header can be set via an environment variable to a string that is parseable as a number, e.g. 1234

• pkg/service: Don't error on startup when process metrics are enabled on unsupported OSes (e.g. AIX) (#​14307)

v1.50.0

🛑 Breaking changes 🛑

• pkg/exporterhelper: Change verbosity level for otelcol_exporter_queue_batch_send_size metric to detailed. (#​14278)
• pkg/service: Remove deprecated telemetry.disableHighCardinalityMetrics feature gate. (#​14373)
• pkg/service: Remove deprecated service.noopTracerProvider feature gate. (#​14374)

🚩 Deprecations 🚩

• exporter/otlp_grpc: Rename otlp exporter to otlp_grpc exporter and add deprecated alias otlp. (#​14403)
• exporter/otlp_http: Rename otlphttp exporter to otlp_http exporter and add deprecated alias otlphttp. (#​14396)

💡 Enhancements 💡

• cmd/builder: Avoid duplicate CLI error logging in generated collector binaries by relying on cobra's error handling. (#​14317)

• cmd/mdatagen: Add the ability to disable attributes at the metric level and re-aggregate data points based off of these new dimensions (#​10726)

• cmd/mdatagen: Add optional display_name and description fields to metadata.yaml for human-readable component names (#​14114)
  The display_name field allows components to specify a human-readable name in metadata.yaml.
  When provided, this name is used as the title in generated README files.
  The description field allows components to include a brief description in generated README files.

• cmd/mdatagen: Validate stability level for entities (#​14425)

• pkg/xexporterhelper: Reenable batching for profiles (#​14313)

• receiver/nop: add profiles signal support (#​14253)

• pkg/service: Add support to disabling adding resource attributes as zap fields in internal logging (#​13869)
  Note that this does not affect logs exported through OTLP.
