v0.107.0

Compare Source

🛑 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)

🛑 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 💡

🧰 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)

• 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.

v0.104.0

Compare Source

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)

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)

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)

v0.102.0

Compare Source

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)

🛑 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::telemetry::metrics::level configuration.
  • Batch processor metrics are updated to be reported starting from normal level:
    • processor_batch_batch_send_size
    • processor_batch_metadata_cardinality

• 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 _.
