(#30775)
• (Contrib) - prometheusreceiver: Allows receiving prometheus native histograms (#26555)
  • Native histograms are compatible with OTEL exponential histograms.
  • The feature can be enabled via the feature gate receiver.prometheusreceiver.EnableNativeHistograms.
    Run the collector with the command line option --feature-gates=receiver.prometheusreceiver.EnableNativeHistograms.
  • Currently the feature also requires that targets are scraped via the ProtoBuf format.
    To start scraping native histograms, set
    config.global.scrape_protocols to [ PrometheusProto, OpenMetricsText1.0.0, OpenMetricsText0.0.1, PrometheusText0.0.4 ] in the
    receiver configuration. This requirement will be lifted once Prometheus can scrape native histograms over text formats.
  • For more up to date information see the README.md file of the receiver at
    https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/prometheusreceiver/README.md#prometheus-native-histograms.

v0.97.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.97.0 and the opentelemetry-collector-contrib v0.97.0 releases where appropriate.

⚠️ Upgrade guidelines regarding the collector memory ballast. ⚠️

reproduced from repository README

memory_ballast is no longer effective. The garbage collection is now controlled by the soft memory limit set to 90% of total memory (SPLUNK_MEMORY_TOTAL_MIB env var) by default.

If you haven't customized the memory_ballast, just remove it from the configuration.

If you have customized it via SPLUNK_BALLAST_SIZE_MIB (or extensions::memory_ballast::size_mib config), you should remove the memory_ballast extension and use the GOMEMLIMIT environment variable to set a custom soft memory limit:

To increase frequency of garbage collections: set GOMEMLIMIT to a higher value than the default 90% of total memory.
To decrease frequency of garbage collections: set GOMEMLIMIT to a lower value than the default 90% of total memory.

🚀 New components 🚀

• (Contrib) awss3exporter: Add support for encoding extension to awss3exporter (#30554)
• (Contrib) deltatocumulativeprocessor: introduce configurable stream limit (#31488)
  Adds max_streams option that allows to set upper bound (default = unlimited)
  to the number of tracked streams. Any additional streams exceeding the limit
  are dropped.
• (Contrib) fileexporter: Adopt the encoding extension with the file exporter. (#31774)
• (Contrib) pkg/ottl: Add ParseXML function for parsing XML from a target string. (#31133)
• (Contrib) fileexporter: Added the option to write telemetry data into multiple files, where the file path is based on a resource attribute. (#24654)

🛑 Breaking changes 🛑

• (Splunk) collectd/kong: Remove collectd/kong. Please use the Prometheus receiver instead. (#4420)
• (Splunk) spanmetricsprocessor: Remove spanmetricsprocessor. Please use spanmetrics connector instead. (#4454)
• (Core) telemetry: Remove telemetry.useOtelForInternalMetrics stable feature gate (#9752)
• (Contrib) receiver/postgresql: Bump postgresqlreceiver.preciselagmetrics gate to beta (#31220)

  See https://prometheus.io/docs/prometheus/latest/configuration/configuration/#configuration-file for details on setting scrape_protocols.
• (Contrib) vcenterreceiver: Fixed the resource attribute model to more accurately support multi-cluster deployments (#30879)
  For more information on impacts please refer open-telemetry/opentelemetry-collector-contrib#31113. The main impacts are that
  the vcenter.resource_pool.name, vcenter.resource_pool.inventory_path, and vcenter.cluster.name are reported with more accuracy on VM metrics.

🧰 Bug fixes 🧰

• (Splunk) telemetry: Simplify the config converter setting the metric_relabel_configs in the Prometheus receiver
  to remove the excessive internal metrics. Now, it only overrides the old default rule excluding .*grpc_io.* metrics.
  Any other custom setting is left untouched. Otherwise, customizing the metric_relabel_configs is very difficult.
  (#4482)
• (Core) exporterhelper: Fix persistent queue size backup on reads. (#9740)

• (Contrib) hostmetricsreceiver: Adds the receiver.hostmetrics.normalizeProcessCPUUtilization feature gate to optionally normalize process.cpu.utilization values. (#31368)
  When enabled, the receiver.hostmetrics.normalizeProcessCPUUtilization feature gate will cause process.cpu.utilization values to be divided by the number of logical cores on the system. This is necessary to produce a value on the interval of [0-1], as the description of process.cpu.utilization the metric says.
• (Contrib) transformprocessor: Change metric unit for metrics extracted with extract_count_metric() to be the default unit (1) (#31575)
  The original metric unit does not apply to extracted count metrics the same way it does to sum, min or max.
  Metrics extracted using extract_count_metric() now use the more appropriate default unit (1) instead.
• (Contrib) loadbalancingexporter: Fix memory leaks on shutdown (#31050)
• (Contrib) signalfxexporter: Fix memory leak in shutdown (#30864, #30438)
• (Contrib) processor/k8sattributes: Allows k8sattributes processor to work with k8s role/rolebindings when filter::namespace is set. ([#14742](https://github.com/ope...

v0.94.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.94.1 and the opentelemetry-collector-contrib v0.94.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) The Splunk OpenTelemetry Collector Windows install script
  now installs the Splunk Distribution of OpenTelemetry .NET
  instead of the SignalFx Instrumentation for .NET
  when the parameter -with_dotnet_instrumentation is set to $true (#4343)
• (Core) receiver/otlp: Update gRPC code from codes.InvalidArgument to codes.Internal when a permanent error doesn't contain a gRPC status (#9415)
• (Contrib) kafkareceiver: standardizes the default topic name for metrics and logs receivers to the same topic name as the metrics and logs exporters of the kafkaexporter (#27292)
  If you are using the Kafka receiver in a logs and/or a metrics pipeline
  and you are not customizing the name of the topic to read from with the topic property,
  the receiver will now read from otlp_logs or otlp_metrics topic instead of otlp_spans topic.
  To maintain previous behavior, set the topic property to otlp_spans.
• (Contrib) pkg/stanza: Entries are no longer logged during error conditions. (#26670)
  This change is being made to ensure sensitive information contained in logs are never logged inadvertently.
  This change is a breaking change because it may change user expectations. However, it should require
  no action on the part of the user unless they are relying on logs from a few specific error cases.
• (Contrib) pkg/stanza: Invert recombine operator's 'overwrite_with' default value. (#30783)
  Previously, the default value was oldest, meaning that the recombine operator should emit the
  first entry from each batch (with the recombined field). However, the actual behavior was inverted.
  This fixes the bug but also inverts the default setting so as to effectively cancel out the bug fix
  for users who were not using this setting. For users who were explicitly setting overwrite_with,
  this corrects the intended behavior.

  The validation used to enforce that usernames cannot be empty.
• (Contrib) pkg/ottl: Fix parsing of string escapes in OTTL (#23238)
• (Contrib) pkg/stanza: Recombine operator should always recombine partial logs (#30797)
  Previously, certain circumstances could result in partial logs being emitted without any
  recombiniation. This could occur when using is_first_entry, if the first partial log from
  a source was emitted before a matching "start of log" indicator was found. This could also
  occur when the collector was shutting down.
• (Contrib) pkg/stanza: Fix bug where recombine operator's 'overwrite_with' condition was inverted. (#30783)
• (Contrib) exporter/signalfx: Use "unknown" value for the environment correlation calls as fallback. (#31052)
  This fixed the APM/IM correlation in the Splunk Observability UI for the users that send traces with no "deployment.environment" resource attribute value set.

v0.93.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.93.0 and the opentelemetry-collector-contrib v0.93.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) On Windows the SPLUNK_* environment variables were moved from the machine scope to the collector service scope This avoids collisions with other agents and instrumentation. If any of these environment variables are required by your apps, please adopt them directly. (#3930)
• (Splunk) mysql discovery now uses the OpenTelemetry Collector Contrib receiver by default instead of the smartagent receiver. (#4231)
• (Splunk) Stop sending internal Collector metrics from the batch processor. Drop them at the prometheus receiver level. (#4273)
• (Core) exporterhelper: remove deprecated exporterhelper.RetrySettings and exporterhelper.NewDefaultRetrySettings (#9256)
• (Contrib) vcenterreceiver: "receiver.vcenter.emitPerfMetricsWithObjects" feature gate is beta and enabled by default (#30615)
• (Contrib) docker: Adopt api_version as strings to correct invalid float truncation (#24025)
• (Contrib) extension/filestorage: Replace path-unsafe characters in component names (#3148)
  The feature gate extension.filestorage.replaceUnsafeCharacters is now enabled by default.
  See the File Storage extension's README for details.
• (Contrib) postgresqlreceiver: add feature gate receiver.postgresql.separateSchemaAttr to include schema as separate attribute (#29559)
  Enabling the featuregate adds a new resource attribute to store the schema of the table or index
  Existing table attributes are adjusted to not include the schema, which was inconsistently used

💡 Enhancements 💡

• (Splunk) Update opentelemetry-jmx-metrics version to 1.32.0 (#4201)
• (Core) 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.
• (Core) service: mark telemetry.useOtelForInternalMetrics as stable (#816)
  (Splunk) Remove disabled telemetry.useOtelForInternalMetrics feature gate from our distribution. Some new internal metrics are now dropped at scrape time.
• (Core) 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".
• (Contrib) pkg/stanza: Add a json array parser operator and an assign keys transformer. (#30321)
  Json array parser opreator can be used to parse a json array string input into a list of objects. |
  Assign keys transformer can be used to assigns keys from the configuration to an input list

v0.92.0

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)

v0.91.3

🛑 Breaking changes 🛑

• (Splunk) - ecs-metadata sync the known_status property on the container_id dimension instead of lower cardinality container_name. This can be prevented by configuring dimensionToUpdate to container_name (#4091)
• (Splunk) Removes collectd/disk monitor (#3998)
  This monitor has been deprecated in favor of the disk-io monitor.
  Note that the disk-io monitor has a different dimension (disk
  instead of plugin_instance) to specify the disk.
• (Splunk) Removes collectd/df monitor (#3996)
  The monitor is deprecated and the filesystems monitor should be used instead.
• (Splunk) Removes netinterface monitor (#3991)
  This monitor is deprecated in favor of the net-io monitor.
• (Splunk) Removes collectd/vmem monitor (#3993)
  This monitor is deprecated in favor of the vmem monitor. The metrics should be fully compatible with this monitor.
• (Splunk) Removes collectd/load monitor (#3995)
  This monitor has been deprecated in favor of the load monitor. That monitor emits the same metrics and is fully compatible.
• (Splunk) Removes collectd/postgresql monitor (#3994)
  This monitor is deprecated in favor of the postgresql monitor.
