This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.92.0 and the opentelemetry-collector-contrib v0.92.0 releases where appropriate.

🛑 Breaking changes 🛑

  • (Contrib) httpforwarder: Use confighttp.HTTPDefaultClientSettings when configuring the HTTPClientSettings for the httpforwarder extension. (#6641)
    By default, the HTTP forwarder extension will now use the defaults set in the extension:
    • The idle connection timeout is set to 90s.
    • The max idle connection count is set to 100.
  • (Contrib) pkg/ottl: Now validates against extraneous path segments that a context does not know how to use. (#30042)
  • (Contrib) pkg/ottl: Throw an error if keys are used on a path that does not allow them. (#30162)
  • (Core) 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.
  • (Core) 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.

🚩 Deprecations 🚩

  • (Contrib) k8sclusterreceiver: deprecate optional k8s.kubeproxy.version resource attribute (#29748)
  • (Core) exporterhelper: Deprecate exporterhelper.RetrySettings in favor of configretry.BackOffConfig (#9091)
  • (Core) extension/ballast: Deprecate memory_ballast extension. (#8343)
    Use GOMEMLIMIT environment variable instead.

💡 Enhancements 💡

  • (Splunk) support core service validate command (#4175)
  • (Splunk) Add routing connector to Splunk distribution (#4167)
  • (Contrib) adopt splunkhec batch by token and index updates (#4151)
  • (Contrib) vcenterreceiver: Add explicit statement of support for version 8 of ESXi and vCenter (#30274)
  • (Contrib) routingconnector: routingconnector supports matching the statement only once (#26353)
  • (Contrib) filterprocessor: Add telemetry for metrics, logs, and spans that were intentionally dropped via filterprocessor. (#13169)
  • (Contrib) pkg/ottl: Add Hour OTTL Converter (#29468)
  • (Contrib) kafkaexporter: add ability to publish kafka messages with message key of TraceID - it will allow partitioning of the kafka Topic. (#12318)
  • (Contrib) kafkareceiver: Add three new metrics to record unmarshal errors. (#29302)
  • (Contrib) hostmetricsreceiver: Add system.memory.limit metric reporting the total memory available. (#30306)
    This metric is opt-in. To enable it, set scrapers::memory::metrics::system.memory.limit::enabled to true in the hostmetrics config.
  • (Contrib) kafkaexporter: Adds the ability to configure the Kafka client's Client ID. (#30144)
  • (Contrib) pkg/stanza: Remove sampling policy from logger (#23801)
  • (Contrib) resourcedetectionprocessor: Add "aws.ecs.task.id" attribute (#8274)
    Resourcedetectionprocessor now exports "aws.ecs.task.id" attribute, in addition to "aws.ecs.task.arn".
    This allows exporters like "awsemfexporter" to automatically pick up that attribute and make it available
    in templating (e.g. to use in CloudWatch log stream name).
  • (Contrib) spanmetricsconnector: Fix OOM issue for spanmetrics by limiting the number of exemplars that can be added to a unique dimension set (#27451)
  • (Contrib) connector/spanmetrics: Configurable resource metrics key attributes, filter the resource attributes used to create the resource metrics key. (#29711)
    This enhancement can be used to fix broken spanmetrics counters after a span producing service restart, when resource attributes contain dynamic/ephemeral values (e.g. process id).
  • (Contrib) splunkhecreceiver: Returns json response in raw endpoint when it is successful (#29875)
  • (Contrib) sqlqueryreceiver: Swap MS SQL Server driver from legacy 'denisenkom' to official Microsoft fork (#27200)
  • (Core) 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
  • (Core) service: Enable telemetry.useOtelForInternalMetrics by updating the flag to beta (#7454)
    The metrics generated should be consistent with the metrics generated
    previously with OpenCensus. Splunk note: this option is disabled in our distribution. Users can enable the behaviour
    by setting --feature-gates +telemetry.useOtelForInternalMetrics at collector start if the new histograms are desired.
  • (Core) confignet: Add dialer_timeout config option. (#9066)
  • (Core) processor/memory_limiter: Update config validation errors (#9059)
    • Fix names of the config fields that are validated in the error messages
    • Move the validation from start to the initialization phrase
  • (Core) exporterhelper: Add config Validate for TimeoutSettings (#9104)

🧰 Bug fixes 🧰

  • (Contrib) filterset: Fix concurrency issue when enabling caching. (#11829)
  • (Contrib) pkg/ottl: Fix issue with the hash value of a match subgroup in replace_pattern functions. (#29409)
  • (Contrib) prometheusreceiver: Fix configuration validation to allow specification of Target Allocator configuration without providing scrape configurations (#30135)
  • (Contrib) wavefrontreceiver: Return error if partially quoted (#30315)
  • (Contrib) hosmetricsreceiver: change cpu.load.average metrics from 1 to {thread} (#29914)
  • (Contrib) pkg/ottl: Fix bug where the Converter IsBool was not usable (#30151)
  • (Contrib) time: The %z strptime format now correctly parses Z as a valid timezone (#29929)
    strptime(3) says that %z is "an RFC-822/ISO 8601 standard
    timezone specification", but the previous code did not allow the
    string "Z" to signify UTC time, as required by ISO 8601. Now, both
    +0000 and Z are recognized as UTC times in all components that
    handle strptime format strings.
  • (Core) memorylimiterprocessor: Fixed leaking goroutines from memorylimiterprocessor (#9099)
  • (Core) cmd/otelcorecol: Fix the code detecting if the collector is running as a service on Windows. (#7350)
    Removed the NO_WINDOWS_SERVICE environment variable given it is not needed anymore.
  • (Core) otlpexporter: remove dependency of otlphttpreceiver on otlpexporter (#6454)
