End User Changelog

🛑 Breaking changes 🛑

• builder: Add strict version checking when using the builder. Add the temporary flag --skip-strict-versioning for skipping this check. (#9896)
  Strict version checking will error on major and minor version mismatches
  between the otelcol_version configured and the builder version or versions
  in the go.mod. This check can be temporarily disabled by using the --skip-strict-versioning
  flag. This flag will be removed in a future minor version.

• telemetry: Distributed internal metrics across different levels. (#7890)
  The internal metrics levels are updated along with reported metrics:

  • The default level is changed from basic to normal, which can be overridden with service::telmetry::metrics::level configuration.
  • Batch processor metrics are updated to be reported starting from normal level:
    • processor_batch_batch_send_size
    • processor_batch_metadata_cardinality
    • processor_batch_timeout_trigger_send
    • processor_batch_size_trigger_send
  • GRPC/HTTP server and client metrics are updated to be reported starting from detailed level:
    • http.client.* metrics
    • http.server.* metrics
    • rpc.server.* metrics
    • rpc.client.* metrics

💡 Enhancements 💡

• confighttp: Disable concurrency in zstd compression (#8216)

• cmd/builder: Allow configuring confmap.Providers in the builder. (#4759)
  If no providers are specified, the defaults are used.
  The default providers are: env, file, http, https, and yaml.

  To configure providers, use the providers key in your OCB build
  manifest with a list of Go modules for your providers.
  The modules will work the same as other Collector components.

• mdatagen: enable goleak tests by default via mdatagen (#9959)

• cmd/mdatagen: support excluding some metrics based on string and regexes in resource_attributes (#9661)

• cmd/mdatagen: Generate config and factory tests covering their requirements. (#9940)
  The tests are moved from cmd/builder.

• confmap: Add ProviderSettings, ConverterSettings, ProviderFactories, and ConverterFactories fields to confmap.ResolverSettings (#9516)
  This allows configuring providers and converters, which are instantiated by NewResolver using the given factories.

🧰 Bug fixes 🧰

• exporter/otlp: Allow DNS scheme to be used in endpoint (#4274)
• service: fix record sampler configuration (#9968)
• service: ensure the tracer provider is configured via go.opentelemetry.io/contrib/config (#9967)

🛑 Breaking changes 🛑

• service: emit internal collector metrics with _ instead of / with OTLP export (#9774)
  This is addressing an issue w/ the names of the metrics generated by the Collector for its
  internal metrics. Note that this change only impacts users that emit telemetry using OTLP, which
  is currently still in experimental support. The prometheus metrics already replaced / with _
  and they will do the same with _.

💡 Enhancements 💡

• mdatagen: Adds unsupported platforms to the README header (#9794)
• confmap: Clarify the use of embedded structs to make unmarshaling composable (#7101)
• nopexporter: Promote the nopexporter to beta (#7316)
• nopreceiver: Promote the nopreceiver to beta (#7316)
• otlpexporter: Checks for port in the config validation for the otlpexporter (#9505)
• service: Validate pipeline type against component types (#8007)

🧰 Bug fixes 🧰

• configtls: Fix issue where IncludeSystemCACertsPool was not consistently used between ServerConfig and ClientConfig. (#9835)
• component: Fix issue where the components command wasn't properly printing the component type. (#9856)
• otelcol: Fix issue where the validate command wasn't properly printing valid component type. (#9866)
• receiver/otlp: Fix bug where the otlp receiver did not properly respond with a retryable error code when possible for http (#9357)

🛑 Breaking changes 🛑

• component: Restricts maximum length for component.Type to 63 characters. (#9872)
• configgrpc: Remove deprecated ToServerContext, use ToServer instead. (#9836)
• configgrpc: Remove deprecated SanitizedEndpoint. (#9836)
• configtls: Remove Deprecated TLSSetting, TLSClientSetting, and TLSServerSetting. (#9786)
• configtls: Rename TLSSetting to Config on ClientConfig and ServerConfig. (#9786)

🚩 Deprecations 🚩

• confighttp: Deprecate ToClient,ToListenerand ToServer use ToClientContext,ToListenerContext and ToServerContextinstead. (#9807)
• configtls: Deprecate ClientConfig.LoadTLSConfig and ServerConfig.LoadTLSConfig, use ClientConfig.LoadTLSConfigContext and ServerConfig.LoadTLSConfigContext instead. (#9811)

💡 Enhancements 💡

• Introduce new module for generating pdata: pdata/testdata (#9886)

• exporterhelper: Make the WithBatcher option available for regular exporter helpers based on OTLP data type. (#8122)
  Now, WithBatcher can be used with both regular exporter helper (e.g. NewTracesExporter) and the request-based exporter
  helper (e.g. NewTracesRequestExporter). The request-based exporter helpers require WithRequestBatchFuncs option
  providing batching functions.

• confmap: Creates a logger in the confmap.ProviderSettings and uses it to log when there is a missing or blank environment variable referenced in config. For now the noop logger is used everywhere except tests. (#5615)
