Release Notes

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

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.

💡 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 temporaly 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 🧰

• exporterhelper: Fix memory leak at exporter shutdown (#​11401)
• sharedcomponent: Remove race-condition and cleanup locking (#​11819)

v1.21.0

🛑 Breaking changes 🛑

• otelcol: Change all logged timestamps to ISO8601. (#​10543)
  This makes log timestamps human-readable (as opposed to epoch seconds in
  scientific notation), but may break users trying to parse logged lines in the
  old format.
• pdata/pprofile: Upgrade pdata to opentelemetry-proto v1.4.0 (#​11722)

🚩 Deprecations 🚩

• scraperhelper: Deprecate all Scraper helpers in scraperhelper (#​11732)
  Deprecate ScrapeFunc, ScraperOption, WithStart, WithShutdown in favor of equivalent funcs in scraper package.

💡 Enhancements 💡

• exporterqueue: Introduce a feature gate exporter.UsePullingBasedExporterQueueBatcher to use the new pulling model in exporter queue batching. (#​8122, #​10368)
  If both queuing and batching is enabled for exporter, we now use a pulling model instead of a
  pushing model. num_consumer in queue configuration is now used to specify the maximum number of
  concurrent workers that are sending out the request.

• service: label metrics as alpha to communicate their stability (#​11729)

• consumer: Mark consumer as stable. (#​9046)

• service: Add support for ca certificates in telemetry metrics otlp grpc exporter (#​11633)
  Before this change the Certificate value in config was silently ignored.

• featuregate: Fix an unfriendly display message runtime error when featuregate is used to display command line usage. (#​11651)
• profiles: Fix iteration over scope profiles while counting the samples. (#​11688)

v1.20.0

💡 Enhancements 💡

• cmd/builder: Allow for replacing of local Providers and Converters when building custom collector with ocb. (#​11649)
  Use the property path under gomod to replace an go module with a local folder in
  builder-config.yaml. Ex:
  providers:
  - gomod: module.url/my/custom/provider v1.2.3
  path: /path/to/local/provider

• cmd/builder: Allow configuring confmap.Converter components in ocb. (#​11582)
  If no converters are specified, there will be no converters added.
  Currently, the only published converter is expandconverter which is
  deprecated as of v0.107.0, but can still be added for testing purposes.

  To configure a custom converter, make sure your converter implements the converter
  interface and is published as a go module (or replaced locally if not published).
  You may then use the converters key in your OCB build manifest with a list of
  Go modules (and replaces as necessary) to include your converter.

  Please note that converters are order-dependent. The confmap will apply converters
  in order of which they are listed in your manifest if there is more than one.

• all: shorten time period before removing an unmaintained component from 6 months to 3 months (#​11664)

🧰 Bug fixes 🧰

• all: Updates dialer timeout section documentation in confignet README (#​11685)
• scraperhelper: If the scraper shuts down, do not scrape first. (#​11632)
  When the scraper is shutting down, it currently will scrape at least once.
  With this change, upon receiving a shutdown order, the receiver's scraperhelper will exit immediately.

• service: implement a no-op tracer provider that doesn't propagate the context (#​11026)
  The no-op tracer provider supported by the SDK incurs a memory cost of propagating the context no matter
  what. This is not needed if tracing is not enabled in the Collector. This implementation of the no-op tracer
  provider removes the need to allocate memory when tracing is disabled.

• confmap: Use string representation for field types where all primitive types are strings. (#​10937)
• otelcol: Preserve internal representation when unmarshaling component configs (#​10552)

v1.13.0

🛑 Breaking changes 🛑

💡 Enhancements 💡

• mdatagen: export ScopeName in internal/metadata package (#​10845)
  This can be used by components that need to set their scope name manually. Will save component owners from having to store a variable, which may diverge from the scope name used by the component for emitting its own telemetry.

• semconv: Add v1.26.0 semantic conventions package (#​10249, #​10829)

• mdatagen: Expose a setting on tests::host to set up your own host initialization code (#​10765)

• semconv: Add semantic conventions version v1.27.0 (#​10837)

• client: Mark module as stable. (#​10775)

🧰 Bug fixes 🧰

• configtelemetry: Add 10s read header timeout on the configtelemetry Prometheus HTTP server. (#​5699)

• service: Allow users to disable the tracer provider via the feature gate service.noopTracerProvider (#​10858)
  The service is returning an instance of a SDK tracer provider regardless of whether there were any processors configured causing resources to be consumed unnecessarily.

• processorhelper: Fix processor metrics not being reported initially with 0 values. (#​10855)

• service: Implement the temporality_preference setting for internal telemetry exported via OTLP (#​10745)

• configauth: Fix unmarshaling of authentication in HTTP servers. (#​10750)

  This makes the ${env:ENV} syntax closer to how ${ENV} worked before unifying syntaxes.

• component: Allow component names of up to 1024 characters in length. (#​10816)

• confmap: Remove original string representation if invalid. (#​10787)

v1.12.0

🛑 Breaking changes 🛑

• service: add service.disableOpenCensusBridge feature gate which is enabled by default to remove the dependency on OpenCensus (#​10414)
• confmap: Promote confmap.strictlyTypedInput feature gate to beta. (#​10552)
  This feature gate changes the following:
  • Configurations relying on the implicit type casting behaviors listed on #​9532 will start to fail.
  • Configurations using URI expansion (i.e. field: ${env:ENV}) for string-typed fields will use the value passed in ENV verbatim without intermediate type casting.

💡 Enhancements 💡

• configtls: Mark module as stable. (#​9377)
• confmap: Remove extra closing parenthesis in sub-config error (#​10480)
• configgrpc: Update the default load balancer strategy to round_robin (#​10319)

• exporterhelper: Fix incorrect deduplication of otelcol_exporter_queue_size and otelcol_exporter_queue_capacity metrics if multiple exporters are used. (#​10444)
• service/telemetry: Add ability to set service.name for spans emitted by the Collector (#​10489)
• internal/localhostgate: Correctly log info message when component.UseLocalHostAsDefaultHost is enabled (#​8510)

v1.11.0

This release includes 2 very important breaking changes.

1. The otlpreceiver will now use localhost by default instead of 0.0.0.0. This may break the receiver in containerized environments like Kubernetes. If you depend on 0.0.0.0 disable the component.UseLocalHostAsDefaultHost feature gate or explicitly set the endpoint to 0.0.0.0.
2. Expansion of BASH-style environment variables, such as $FOO will no longer be supported by default. If you depend on this syntax, disable the confmap.unifyEnvVarExpansion feature gate, but know that the feature will be removed in the future in favor of ${env:FOO}.

🛑 Breaking changes 🛑

• filter: Remove deprecated filter.CombinedFilter (#​10348)
• otelcol: By default, otelcol.NewCommand and otelcol.NewCommandMustSetProvider will set the DefaultScheme to env. (#​10435)
• expandconverter: By default expandconverter will now error if it is about to expand $FOO syntax. Update configuration to use ${env:FOO} instead or disable the confmap.unifyEnvVarExpansion feature gate. (#​10435)
• otlpreceiver: Switch to localhost as the default for all endpoints. (#​8510)
  Disable the component.UseLocalHostAsDefaultHost feature gate to temporarily get the previous default.

💡 Enhancements 💡

• confighttp: Add support for cookies in HTTP clients with cookies::enabled. (#​10175)
  The method confighttp.ToClient will return a client with a cookiejar.Jar which will reuse cookies from server responses in subsequent requests.
• exporter/debug: In normal verbosity, display one line of text for each telemetry record (log, data point, span) (#​7806)
• exporter/debug: Add option use_internal_logger (#​10226)
• configretry: Mark module as stable. (#​10279)
• debugexporter: Print Span.TraceState() when present. (#​10421)
  Enables viewing sampling threshold information (as by OTEP 235 samplers).
• processorhelper: Add "inserted" metrics for processors. (#​10353)
  This includes the following metrics for processors:
  • processor_inserted_spans
  • processor_inserted_metric_points
  • processor_inserted_log_records

🧰 Bug fixes 🧰

• otlpexporter: Update validation to support both dns:// and dns:/// (#​10449)

v1.10.0

🛑 Breaking changes 🛑

• exporter/debug: Disable sampling by default (#​9921)
  To restore the behavior that was previously the default, set sampling_thereafter to 500.

💡 Enhancements 💡

• cmd/builder: Allow setting otelcol.CollectorSettings.ResolverSettings.DefaultScheme via the builder's conf_resolver.default_uri_scheme configuration option (#​10296)
• mdatagen: add support for optional internal metrics (#​10316)
• otelcol/expandconverter: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#​10391)
  When enabled, this feature gate will:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was `${env:FOO}
    See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• confmap: Add confmap.unifyEnvVarExpansion feature gate to allow enabling Collector/Configuration SIG environment variable expansion rules. (#​10259)
  When enabled, this feature gate will:
  • Disable expansion of BASH-style env vars ($FOO)
  • ${FOO} will be expanded as if it was `${env:FOO}
    See https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/env-vars.md for more details.
• confighttp: Allow the compression list to be overridden (#​10295)
  Allows Collector administrators to control which compression algorithms to enable for HTTP-based receivers.
• configgrpc: Revert the zstd compression for gRPC to the third-party library we were using previously. (#​10394)
  We switched back to our compression logic for zstd when a CVE was found on the third-party library we were using. Now that the third-party library has been fixed, we can revert to that one. For end-users, this has no practical effect. The reproducers for the CVE were tested against this patch, confirming we are not reintroducing the bugs.
• confmap: Adds alpha confmap.strictlyTypedInput feature gate that enables strict type checks during configuration resolution (#​9532)
  When enabled, the configuration resolution system will:
  • Stop doing most kinds of implicit type casting when resolving configuration values
  • Use the original string representation of configuration values if the ${} syntax is used in inline position
• confighttp: Use confighttp.ServerConfig as part of zpagesextension. See server configuration options. (#​9368)

• exporterhelper: Fix small batch due to unfavorable goroutine scheduling in batch sender (#​9952)
• confmap: Fix issue where structs with only yaml tags were not marshaled correctly. (#​10282)

v1.9.0

This release addresses GHSA-c74f-6mfw-mm4v for confighttp.

🛑 Breaking changes 🛑

• envprovider: Restricts Environment Variable names. Environment variable names must now be ASCII only and start with a letter or an underscore, and can only contain underscores, letters, or numbers. (#​9531)
• confighttp: Apply MaxRequestBodySize to the result of a decompressed body. This addresses GHSA-c74f-6mfw-mm4v for confighttp (#​10289)
  When using compressed payloads, the Collector would verify only the size of the compressed payload.
  This change applies the same restriction to the decompressed content. As a security measure, a limit of 20 MiB was added, which makes this a breaking change.
  For most clients, this shouldn't be a problem, but if you often have payloads that decompress to more than 20 MiB, you might want to either configure your
  client to send smaller batches (recommended), or increase the limit using the MaxRequestBodySize option.

💡 Enhancements 💡

• mdatagen: auto-generate utilities to test component telemetry (#​19783)
• mdatagen: support setting an AttributeSet for async instruments (#​9674)
• mdatagen: support using telemetry level in telemetry builder (#​10234)
  This allows components to set the minimum level needed for them to produce telemetry. By default, this is set to configtelemetry.LevelBasic. If the telemetry level is below that minimum level, then the noop meter is used for metrics.
• mdatagen: add support for bucket boundaries for histograms (#​10218)
• releases: add documentation in how to verify the image signatures using cosign (#​9610)

🧰 Bug fixes 🧰

• batchprocessor: ensure attributes are set on cardinality metadata metric (#​9674)
• batchprocessor: Fixing processor_batch_metadata_cardinality which was broken in v0.101.0 (#​10231)
• batchprocessor: respect telemetry level for all metrics (#​10234)
• exporterhelper: Fix potential deadlocks in BatcherSender shutdown (#​10255)

v1.8.0

💡 Enhancements 💡

• mdatagen: generate documentation for internal telemetry (#​10170)

• mdatagen: add ability to use metadata.yaml to automatically generate instruments for components (#​10054)
  The telemetry section in metadata.yaml is used to generate
  instruments for components to measure telemetry about themselves.

• confmap: Allow Converters to write logs during startup (#​10135)

• otelcol: Enable logging during configuration resolution (#​10056)

🧰 Bug fixes 🧰

• mdatagen: Run package tests when goleak is skipped (#​10125)

v1.7.0

🛑 Breaking changes 🛑

• service: The validate sub-command no longer validates that each pipeline's type is the same as its component types (#​10031)

💡 Enhancements 💡

• semconv: Add support for v1.25.0 semantic convention (#​10072)
• builder: remove the need to go get a module to address ambiguous import paths (#​10015)
• pmetric: Support parsing metric.metadata from OTLP JSON. (#​10026)

🧰 Bug fixes 🧰

• exporterhelper: Fix enabled config option for batch sender (#​10076)

v1.6.0

🛑 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)
