• service: Removes stable service.disableOpenCensusBridge feature gate (#11009)

🚩 Deprecations 🚩

• processorhelper: These funcs are not used anywhere, marking them deprecated. (#11083)

🚀 New components 🚀

• extension/experimental/storage: Move extension/experimental/storage into a separate module (#11022)

💡 Enhancements 💡

• configtelemetry: Add guidelines for each level of component telemetry (#10286)

• service: move useOtelWithSDKConfigurationForInternalTelemetry gate to beta (#11091)

• 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.

• envprovider: Mark module as stable (#10982)

• fileprovider: Mark module as stable (#10983)

• processor: Add incoming and outgoing counts for processors using processorhelper. (#10910) Any processor using the processorhelper package (this is most processors) will automatically report incoming and outgoing item counts. The new metrics are:

  • otelcol_processor_incoming_spans
  • otelcol_processor_outgoing_spans
  • otelcol_processor_incoming_metric_points
  • otelcol_processor_outgoing_metric_points
  • otelcol_processor_incoming_log_records
  • otelcol_processor_outgoing_log_records

• 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/v0.107.0

🛑 Breaking changes 🛑

• service: Remove OpenCensus bridge completely, mark feature gate as stable. (#10414)
• confmap: Set the confmap.unifyEnvVarExpansion feature gate to Stable. Expansion of $FOO env vars is no longer supported. Use ${FOO} or ${env:FOO} instead. (#10508)
• service: Remove otelcol from Prometheus configuration. This means that any metric that isn't explicitly prefixed with otelcol_ no longer have that prefix. (#9759)

💡 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) Some receivers require a host that has additional capabilities such as exposing exporters. For those, we can expose a setting that allows them to place a different host in the generated code.

• confmap: Allow using any YAML structure as a string when loading configuration. (#10800) Previous to this change, slices could not be used as strings in configuration.

• ocb: migrate build and release of ocb binaries to opentelemetry-collector-releases repository (#10710) ocb binaries will now be released under open-telemetry/opentelemetry-collector-releases tagged as "cmd/builder/vX.XXX.X"

• 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)

• confmap: If loading an invalid YAML string through a provider, use it verbatim instead of erroring out. (#10759) 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)

v0.106.1

🧰 Bug fixes 🧰

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

v0.106.0

🛑 Breaking changes 🛑

• service: Update all metrics to include otelcol_ prefix to ensure consistency across OTLP and Prometheus metrics (#9759) This change is marked as a breaking change as anyone that was using OTLP for metrics will see the new prefix which was not present before. Prometheus generated metrics remain unchanged.

• confighttp: Delete ClientConfig.CustomRoundTripper (#8627) Set (*http.Client).Transport on the *http.Client returned from ToClient to configure this.

• confmap: When passing configuration for a string field using any provider, use the verbatim string representation as the value. (#10605, #10405) This matches the behavior of ${ENV} syntax prior to the promotion of the confmap.unifyEnvVarExpansion feature gate to beta. It changes the behavior of the ${env:ENV} syntax with escaped strings.

• component: Adds restrictions on the character set for component.ID name. (#10673)

• processor/memorylimiter: The memory limiter processor will no longer account for ballast size. (#10696) If you are already using GOMEMLIMIT instead of the ballast extension this does not affect you.

• extension/memorylimiter: The memory limiter extension will no longer account for ballast size. (#10696) If you are already using GOMEMLIMIT instead of the ballast extension this does not affect you.

• service: The service will no longer be able to get a ballast size from the deprecated ballast extension. (#10696) If you are already using GOMEMLIMIT instead of the ballast extension this does not affect you.

🚀 New components 🚀

• client: Create a new go module go.opentelemetry.io/collector/client (#9804) This module contains generic representations of clients connecting to different receivers.

💡 Enhancements 💡

• exporterhelper: Add data_type attribute to otelcol_exporter_queue_size metric to report the type of data being processed. (#9943)
• confighttp: Add option to include query params in auth context (#4806)
• configgrpc: gRPC auth errors now return gRPC status code UNAUTHENTICATED (16) (#7646)
• httpprovider, httpsprovider: Validate URIs in HTTP and HTTPS providers before fetching. (#10468)

🧰 Bug fixes 🧰

• processorhelper: update units for internal telemetry (#10647)
• confmap: Increase the amount of recursion and URI expansions allowed in a single line (#10712)
• exporterhelper: There is no guarantee that after the exporterhelper sends the plog/pmetric/ptrace data downstream that the data won't be mutated in some way. (e.g by the batch_sender) This mutation could result in the proceeding call to req.ItemsCount() to provide inaccurate information to be logged. (#10033)
• exporterhelper: Update units for internal telemetry (#10648)
• receiverhelper: Update units for internal telemetry (#10650)
• scraperhelper: Update units for internal telemetry (#10649)
• service: Use Command/Version to populate service name/version attributes (#10644)

v1.12.0/v0.105.0

🛑 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) To restore the behavior that was previously the default, set balancer_name to pick_first.
• cmd/builder: Add go module info the builder generated code. (#10570)
• otelcol: Add go module to components subcommand. (#10570)
• confmap: Add explanation to errors related to confmap.strictlyTypedInput feature gate. (#9532)
• confmap: Allow using map[string]any values in string interpolation (#10605)

🧰 Bug fixes 🧰

• builder: provide context when a module in the config is missing its gomod value (#10474)
• confmap: Fixes issue where confmap could not escape $$ when confmap.unifyEnvVarExpansion is enabled. (#10560)
• mdatagen: fix generated comp test for extensions and unused imports in templates (#10477)
• otlpreceiver: Fixes a bug where the otlp receiver's http response was not properly translating grpc error codes to http status codes. (#10574)
• 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/v0.104.0

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)
• service: Fixed a bug that caused otel-collector to fail to start with ipv6 metrics endpoint service telemetry. (#10011)

v1.10.0/v0.103.0

🛑 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)

🧰 Bug fixes 🧰

• exporterhelper: Fix potential deadlock in the batch sender (#10315)
• expandconverter: Fix bug where an warning was logged incorrectly. (#10392)
• exporterhelper: Fix a bug when the retry and timeout logic was not applied with enabled batching. (#10166)
• exporterhelper: Fix a bug where an unstarted batch_sender exporter hangs on shutdown (#10306)
• 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)

v0.102.1

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

🧰 Bug fixes 🧰

• configrpc: Use own compressors for zstd. Before this change, the zstd compressor we used didn't respect the max message size. This addresses GHSA-c74f-6mfw-mm4v for configgrpc (#10323)

v1.9.0/v0.102.0

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 🧰

💡 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)

🧰 Bug fixes 🧰

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

v1.6.0/v0.99.0

🛑 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)

v1.5.0/v0.98.0

🛑 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 _.

• exporterhelper: remove deprecated exporterhelper.RetrySettings and exporterhelper.NewDefaultRetrySettings (#9256)
• configopaque: configopaque.String implements fmt.Stringer and fmt.GoStringer, outputting [REDACTED] when formatted with the %s, %q or %#v verbs(#9213) This may break applications that rely on the previous behavior of opaque strings withfmt.Sprintfto e.g. build URLs or headers. Explicitly cast the opaque string to a string before using it infmt.Sprintf` to restore the previous behavior.

🚀 New components 🚀

• extension/memory_limiter: Introduce a memory_limiter extension which receivers can use to reject incoming requests when collector doesn't have enough memory (#8632) The extension has the same configuration interface and behavior as the existing memory_limiter processor, which potentially can be deprecated and removed in the future

💡 Enhancements 💡

• configtls: add cipher_suites to configtls. (#8105) Users can specify a list of cipher suites to pick from. If left blank, a safe default list is used.

• service: mark telemetry.useOtelForInternalMetrics as stable (#816)

• exporters: Cleanup log messages for export failures (#9219)

  1. Ensure an error message is logged every time and only once when data is dropped/rejected due to export failure.
  2. Update the wording. Specifically, don't use "dropped" term when an error is reported back to the pipeline. Keep the "dropped" wording for failures happened after the enabled queue.
  3. Properly report any error reported by a queue. For example, a persistent storage error must be reported as a storage error, not as "queue overflow".

🧰 Bug fixes 🧰

• configgrpc: Update dependency to address a potential crash in the grpc instrumentation (#9296)
• otlpreceiver: Ensure OTLP receiver handles consume errors correctly (#4335) Make sure OTLP receiver returns correct status code and follows the receiver contract (gRPC)
• zpagesextension: Remove mention of rpcz page from zpages extension (#9328)

v1.0.1/v0.92.0

🛑 Breaking changes 🛑

• exporters/sending_queue: Do not re-enqueue failed batches, rely on the retry_on_failure strategy instead. (#8382) The current re-enqueuing behavior is not obvious and cannot be configured. It takes place only for persistent queue and only if retry_on_failure::enabled=true even if retry_on_failure is a setting for a different backoff retry strategy. This change removes the re-enqueuing behavior. Consider increasing retry_on_failure::max_elapsed_time to reduce chances of data loss or set it to 0 to keep retrying until requests succeed.

• confmap: Make the option WithErrorUnused enabled by default when unmarshaling configuration (#7102) The option WithErrorUnused is now enabled by default, and a new option WithIgnoreUnused is introduced to ignore errors about unused fields.

• status: Deprecate ReportComponentStatus in favor of ReportStatus. This new function does not return an error. (#9148)

🚩 Deprecations 🚩

• connectortest: Deprecate connectortest.New[Metrics|Logs|Traces]Router in favour of connector.New[Metrics|Logs|Traces]Router (#9095)

• exporterhelper: Deprecate exporterhelper.RetrySettings in favor of configretry.BackOffConfig (#9091)

• extension/ballast: Deprecate memory_ballast extension. (#8343) Use GOMEMLIMIT environment variable instead.

• connector: Deprecate [Metrics|Logs|Traces]Router in favour of [Metrics|Logs|Traces]RouterAndConsumer (#9095)

💡 Enhancements 💡

• exporterhelper: Add RetrySettings validation function (#9089) Validate that time.Duration, multiplier values in configretry are non-negative, and randomization_factor is between 0 and 1

• service: Enable telemetry.useOtelForInternalMetrics by updating the flag to beta (#7454) The metrics generated should be consistent with the metrics generated previously with OpenCensus. Users can disable the behaviour by setting --feature-gates -telemetry.useOtelForInternalMetrics at collector start.

• mdatagen: move component from contrib to core (#9172)

• semconv: Generated Semantic conventions 1.22.0. (#8686)

• otlpexporter: remove dependency of otlphttpreceiver on otlpexporter (#6454)

v0.91.0

💡 Enhancements 💡

• statusreporting: Automates status reporting upon the completion of component.Start(). (#7682)
• service: add resource attributes as labels to otel metrics to ensures backwards compatibility with OpenCensus metrics. (#9029)
• semconv: Generated Semantic conventions 1.21. (#9056)
• config/confighttp: Exposes http/2 transport settings to enable health check and workaround golang http/2 issue golang/go#59690 (#9022)
• cmd/builder: running builder version on binaries installed with go install will output the version specified at the suffix. (#8770)

🧰 Bug fixes 🧰

• exporterhelper: fix missed metric aggregations (#9048) This ensures that context cancellation in the exporter doesn't interfere with metric aggregation. The OTel SDK currently returns if there's an error in the context used in Add. This means that if there's a cancelled context in an export, the metrics are now recorded.

• service: Fix bug where MutatesData would not correctly propagate through connectors. (#9053)

v0.90.1

🧰 Bug fixes 🧰

• exporterhelper: Remove noisy log (#9017)

v1.0.0/v0.90.0

🛑 Breaking changes 🛑

• service: To remain backwards compatible w/ the metrics generated today, otel generated metrics will be generated without the _total suffix (#7454)
• service: use WithNamespace instead of WrapRegistererWithPrefix (#8988) Using this functionality in the otel prom exporter fixes a bug where the target_info was prefixed as otelcol_target_info previously.

💡 Enhancements 💡

• exporter/debug: Change default verbosity from normal to basic (#8844) This change has currently no effect, as basic and normal verbosity share the same behavior. This might change in the future though, with the normal verbosity being more verbose than it currently is (see open-telemetry#7806). This is why we are changing the default to basic, which is expected to stay at the current level of verbosity (one line per batch).
• exporterhelper: Fix shutdown logic in persistent queue to not require consumers to be closed first (#8899)
• confighttp: Support proxy configuration field in all exporters that support confighttp (#5761)

v1.0.0-rcv0017/v0.88.0

💡 Enhancements 💡

• fanoutconsumer: Enable runtime assertions to catch incorrect pdata mutations in the components claiming as non-mutating pdata. (#6794) This change enables the runtime assertions to catch unintentional pdata mutations in components that are claimed as non-mutating pdata. Without these assertions, runtime errors may still occur, but thrown by unrelated components, making it very difficult to troubleshoot.

🧰 Bug fixes 🧰

• otelcol: Add optional ConfmapProvider interface for Config Providers (#6596) This allows providing the Collector's configuration as a marshaled confmap.Conf object from a ConfigProvider

• service: Add CollectorConf field to service.Settings (#6596) This field is intended to be used by the Collector to pass its effective configuration to the service.

v1.0.0-rcv0014/v0.82.0

🛑 Breaking changes 🛑

• service: Enable configuration of collector telemetry through prometheus reader (#7641) These options are still experimental. To enable them, users must enable both telemetry.useOtelForInternalMetrics and telemetry.useOtelWithSDKConfigurationForInternalTelemetry feature gates. This change updates metric_readers to readers to align with the configuration working group.

• service: Remove experimental metric_readers.args and metric_reader.type config options. (#7641) These options were experimental and did not have any effect on the configuration of the collector's telemetry. The change aligns the configuration with the latest iteration of the configuration json schema, which may still change in the future.

• otlphttpexporter: Add support for trailing slash in endpoint URL (#8084) URLs like http://localhost:4318/ will now be treated as if they were http://localhost:4318

🧰 Bug fixes 🧰

• connector: Fix connector validation (#7892) Validation of connectors was too aggressive such that a connector that was used in any combination of unsupported roles would fail. Instead, validation should pass as long as each use of the connector has a supported corresponding use.

  • Connectors connect pipelines by acting as an exporter in one or more pipelines and simultaneously as a receiver of corresponding data in one or more other pipelines. For example:
    • The forward connector can export data to another pipeline of the same type. This allows you to merge data from multiple pipelines onto a common pipeline. Or, you can replicate data onto multiple pipelines so that it may be processed in different ways and/or exported to different backends.
    • The count connector can count data of any type. Regardless of the type of data that is counted, it emits counts as metrics onto a metrics pipeline.
  • Connectors are currently disabled by default but can be enabled with the service.connectors feature gate.
