• telemetrygen: ensure validate is called (#35745)

• deltatocumulative: fix meter panic on startup (#35685)
  properly constructs the TelemetryBuilder, so it does not panic on startup, rendering the entire component unusable

• elasticsearchexporter: Log and drop invalid metrics instead of returning error to avoid upstream retries (#35740)

• elasticsearchexporter: Preserve attribute names and metric names on prefix conflict in OTel mapping mode (#35651)
  e.g. if there are attributes "a" and "a.b", they should be sent to Elasticsearch as is, instead of "a.value" and "a.b", in OTel mapping mode

• elasticsearchexporter: Make OTel mapping mode send to data streams only (#35839)
  This prevents auto creating regular indices in OTel mapping mode due to a race condition in Elasticsearch where otel-data index templates are not ready.

• elasticsearchexporter: Sanitize datastream routing fields (#34285)
  Sanitize the dataset and namespace fields according to https://www.elastic.co/guide/en/ecs/current/ecs-data_stream.html.

• oidcauthextension: Fix a goroutine leak during shutdown. (#30438)
  A goroutine leak was found in oidcauthextension. The goroutine leak was caused by the oidcauthextension not closing the idle connections in the client and transport.

• filelogreceiver: Supports add_metadata_from_filepath for Windows filepaths (#35558)

• filelogreceiver: Suppress errors on EBADF when unlocking files. (#35706)
  This error is harmless and happens regularly when delete_after_read is set. This is because we acquire the lock right at the start of the ReadToEnd function and then defer the unlock, but that function also performs the delete. So, by the time it returns and the defer runs the file descriptor is no longer valid.

• kafkareceiver: Fixes issue causing kafkareceiver to block during Shutdown(). (#30789)

• hostmetrics receiver: Fix duplicate filesystem metrics (#34635, #34512)
  The hostmetrics exposes duplicate metrics of identical mounts exposed in namespaces. The duplication causes errors in exporters that are sensitive to duplicate metrics. We can safely drop the duplicates as the metrics should be exactly the same.

• pkg/translator/prometheusremotewrite: Fix metric comparison func in prom translation layer (#35741)

• pkg/ottl: Allow indexing string slice type (#29441)

v0.111.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release, be sure to check the release notes there as well.

🆕 The binary release adds a new OTLP-only distro. Feel free to leave us feedback on this new distro on the opentelemetry-collector-releases issue tracker.

⚠️ The core release removes the logging exporter. See open-telemetry/opentelemetry-collector#11337 for instructions on how to migrate to the debug exporter.

End User Changelog

🛑 Breaking changes 🛑

• instanaexporter: Remove deprecated instanaexporter (#35367)
  Use the otlp exporter instead as explained in IBM's documentation.
• elasticsearchexporter: Drop cumulative temporality histogram and exponential histogram (#35442)
  Cumulative temporality histogram and exponential histogram are not supported by Elasticsearch. Use cumulativetodeltaprocessor to convert cumulative temporality to delta temporality.
• elasticsearchexporter: Implement receiver-based routing under *_dynamic_index config (#34246)
• config: Move component.UseLocalHostAsDefaultHost feature gate to stable. (#35569)
• metricsgenerationprocessor: Generate metrics even when the second metric's value is 0 (#35533)
• signalfxexporter: Do not exclude the metric container.memory.working_set (#35475)
• sqlqueryreceiver: Fail if value for log column in result set is missing, collect errors (#35068)
• windowseventlogreceiver: The 'raw' flag no longer suppresses rendering info. (#34720)
  Previously, this flag controlled two behaviors simultaneously:
  1. Whether or not the body of the log record was an XML string or structured object.
  2. Whether or not rendering info was resolved.
     A separate 'suppress_rendering_info' option now controls rendering info resolution.
     This is considered a breaking change because users setting only the 'raw' flag without also setting the
     new 'suppress_rendering_info' flag may see a performance decrease along with more detailed events.

🚩 Deprecations 🚩

• sapmreceiver: access_token_passthrough is deprecated (#35330)
  • "access_token_passthrough is deprecated."
  • "Please enable include_metadata in the receiver and add the following config to the batch processor:"

  arrow.waiter_limit -> admission.waiter_limit
  (#35021)

• clickhouseexporter: Upgrading stability for traces to beta (#35186)
  The trace exporter has proven to be stable for production deployments.
  Trace configuration is unlikely to receive any significant changes.

• windowseventlogreceiver: Add 'suppress_rendering_info' option. (#34720)
  When this flag is enabled, the receiver will not attempt to resolve rendering info. This can improve performance
  but comes at a cost of losing some details in the event log.

• windowseventlogreceiver: Move artificial "remote_server" field to 'attributes["server.address"]'. (#34720)

🧰 Bug fixes 🧰

• webhookeventreceiver: Fixed a bug where request bodies containing newline characters caused the results to split into multiple log entries (#35028)

🛑 Breaking changes 🛑

• clickhouseexporter: Upgrade trace SpanKind and StatusCode string values (#34799)
  This change updates the output of the trace SpanKind and StatusCode fields to be consistent
  with the specification's enum values. While this change will not break any deployments, it may affect
  queries dependent on the old enum names.

  For more details on old->new values, see this related PR:
  open-telemetry/opentelemetry-collector#6250

• spanmetricsconnector: Improve consistency between metrics generated by spanmetricsconnector. Added traces.span.metrics as default namespace (#33227, #32818)
  Default namespace for the generated metrics is traces.span.metrics now. | The deprecated metrics are: calls, duration and events. | The feature flag connector.spanmetrics.legacyMetricNames was added to revert the behavior.

• servicegraphconnector: Fix histogram metrics miss unit (#34511)
  All metrics will remove the suffix _seconds. It will not introduce breaking change if users use | prometheusexporter or prometheusremotewriteexporter to exporter metrics in pipeline. | In some cases, like using clickhouseexporter(save data in native OTLP format), it will be a breaking change. | Users can use transformprocessor to add back this suffix.

• gitproviderreceiver: The Git Provider Receiver has been renamed to GitHub Receiver. (#34731)

  Update logs and metrics OTel mapping mode to always emit "scope" and zero int, but not emit empty strings for known fields. Breaking change to remove trace_flags from logs.

• elasticsearchexporter: Change default retry.retry_on_status to [429] (#32584)
  To retain the previous behavior, set retry.retry_on_status to [429, 500, 502, 503, 504].

• gitproviderreceiver: Update metric names and attributes to match the newest Semantic Conventions for VCS. (#34278)
  Attribute Changes:

  • branch.name is now ref.name
  • Added a ref.type attribute

• transformprocessor: Promote processor.transform.ConvertBetweenSumAndGaugeMetricContext feature flag from alpha to beta (#34567)

• exporter/datadog: The logs::dump_payloads config option is invalid when the Datadog Agent logs pipeline is enabled (now enabled by default). (#34420)
  An error will be raised if logs::dump_payloads is set while the Datadog Agent logs pipeline is enabled. To avoid this error, remove the logs::dump_payloads config option or temporarily disable the exporter.datadogexporter.UseLogsAgentExporter feature gate.

• vcenterreceiver: Several host performance metrics now return 1 data point per time series instead of 5. (#34708)
  The 5 data points previously sent represented consecutive 20s sampling periods. Depending on the collection interval
  these could easily overlap. Sending just the latest of these data points is more in line with other performance metrics.

  This change also fixes an issue with the googlecloud exporter seeing these datapoints as duplicates.

  Following is the list of affected metrics which will now only report a single datapoint per set of unique attribute values.

  • vcenter.host.cpu.reserved
  • vcenter.host.disk.latency.avg
  • vcenter.host.disk.latency.max
  • vcenter.host.disk.throughput
  • vcenter.host.network.packet.drop.rate
  • vcenter.host.network.packet.error.rate
  • vcenter.host.network.packet.rate
  • vcenter.host.network.throughput
  • vcenter.host.network.usage

v0.107.0

This release fixes CVE-2024-42368 on the bearerauthtokenextension (#34516)

🛑 Breaking changes 🛑

• clickhouseexporter: Add compress option to ClickHouse exporter, with default value of lz4 (#34365)
  This change adds a new compress option to the config field and enables it by default.
  Prior to this change, compression was not enabled by default.
  The only way to enable compression prior to this change was via the DSN URL.
  With this change, lz4 compression will be enabled by default.
  The list of valid options is provided by the underlying clickhouse-go driver.
  While this change is marked as breaking, there should be no effect to existing deployments by enabling compression.
  Compression should improve network performance on most deployments that have a remote ClickHouse server.

🛑 Breaking changes 🛑

• skywalkingexporter: Remove unmaintained component (#23796)
• elasticsearchexporter: Make "dedup" option no-op, always de-duplicate. (#33773)
  Elasticsearch does not permit duplicate keys in JSON objects, so there is no value in being able to configure deduplication.
• elasticsearchexporter: Remove defunct "file" and "fields" configuration settings. (#33803)
  This is a breaking change only because removing the attributes would prevent collector startup if those attributes are specified, but otherwise there is no functional change. These configuration attributes have never done anything.
• stanza: errors from Operator.Process are returned instead of silently ignored. (#33783)
  This public function is affected: https://pkg.go.dev/github.com/open-telemetry/opentelemetry-collector-contrib/pkg/stanza@v0.104.0/operator/helper#WriterOperator.Write
• vcenterreceiver: Enables various vCenter metrics that were disabled by default until v0.105 (#34022)

💡 Enhancements 💡

• pkg/ottl: Added Hex() converter function (#31929)

• pkg/ottl: Add IsRootSpan() converter function. (#32918)
  Converter IsRootSpan() returns true if the span in the corresponding context is root, that means its parent_span_id equals to hexadecimal representation of zero. In all other scenarios function returns false.

• vcenterreceiver: Adds additional vCenter resource pool metrics and a memory_usage_type attribute for vcenter.resource_pool.memory.usage metric to use. (#33607)
  Added "vcenter.resource_pool.memory.swapped", "vcenter.resource_pool.memory.ballooned", and "vcenter.resource_pool.memory.granted"
  metrics. Also added an additional attribute, "memory_usage_type" for "vcenter.resource_pool.memory.usage" metric, which is
  currently under a feature gate.

• kubeletstatsreceiver: Add k8s.pod.memory.node.utilization and k8s.container.memory.node.utilization metrics (#33591)

  This is an experimental feature. By default the feature gate is disabled and trace export uses a default HTTP client.

• elasticsearchexporter: Introduce experimental telemetry.log_request_body and telemetry.log_response_body config (#33854)

• cmd/opampsupervisor: Adds support for forwarding custom messages to/from the agent (#33575)

• geoipprocessor: Add providers configuration and maxmind provider factory (#33269)

• healthcheckv2extension: Add partial gRPC service implementation to healthcheckv2. (#26661)

• healthcheckv2extension: Add support for streaming Watch RPC to healthcheckv2 gRPC service. (#26661)

• healthcheckv2extension: Add HTTP service to healthcheckv2 (#26661)

• splunkhecexporter: Increase the performance of JSON marshaling (#34011)

• pkg/stanza: Add parse_ints config in json parser to support parsing int or float properly (#33696)

• loadbalancingexporter: Adds a new streamID routingKey, which will route based on the datapoint ID. See updated README for details (#32513)

• awsxrayexporter: Allow multiple log group names/arns to be set in environmental variables (#33795)

• dockerobserver: Add hint to error when using float for api_version field (#34043)

• dockerstatsreceiver: Add hint to error when using float for api_version field (#34043)

• pkg/ottl: Emit traces for statement sequence executions to troubleshoot OTTL statements/conditions (#33433)

• pkg/stanza: Bump 'logs.jsonParserArray' and 'logs.assignKeys' feature gates to beta. (#33948)
  This enables the feature gates by default to allow use of the
  json_array_parser and assign_keys operations.

• receiver/filelog: Add filelog.container.removeOriginalTimeField feature-flag for removing original time field (#33946)

• statsdreceiver: Allow configuring summary percentiles (#33701)

• pkg/stanza: Switch to faster json parser lib for container operator (#33929)

• telemetrygen: telemetrygen --rate flag changed from Int64 to Float64 (#33984)

• extension/opamp: Rely on the Collector APIs to do config redaction (#34078)
  Previously all config fields had to be redacted, now configopaque.String is used to determine
  which fields should be redacted. As a result, fields that are not sensitive are no longer redacted.

• azuremonitorreceiver: Upgrade stability to alpha (#33689)

• windowsperfcountersreceiver: windowsperfcountersreceiver now appends an index number to additional instance names that share a name. An example of this is when scraping 
rocess(*) counters with multiple running instances of the same executable. (#32319)
  NOTES

  • This change can expose cardinality issues where the counters were previously collapsed under the non-indexed instance name.
  • The change mimics Windows Performance Monitor behavior: The first instance name remains unchanged, additional instances are suffixed with #<N> where N=1 and is increased for each duplicate.
    • e.g. Given 3 powershell instances, this will return powershell, powershell#1 and powershell#2.

Go API Changelog

No changes.

v0.104.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release, be sure to check the release notes there as well.

⚠️ The Core repository's release includes 2 very important breaking changes.

1. The otlpreceiver now uses 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. This change also affects contrib components which are listed in the release notes below.
2. Expansion of BASH-style environment variables, such as $FOO is no longer 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}.

End User Changelog

🛑 Breaking changes 🛑

• sumologicexporter: removed compress_encoding (#33604)

• exporter/clickhouse: Change behavior of how default database is read from the config (#33693)
  Changed the default database to default.
  The final database will prioritize endpoint, unless database is set to a value not equal to default.
  If neither are specified then it defaults to the default database.
  Possible breaking change if someone has the DSN configured in combination with database config option.

• exporter/clickhouse: Add async_insert config option to enable inserting asynchronously by default. (#33614)
  Adds async_insert config option to enable inserting asynchronously by default.
  To preserve the previous behavior, set async_insert to false in your config.
  When enabled, the exporter will insert asynchronously, which can improve performance for high-throughput deployments.
  The async_insert option can be set to true or false to enable or disable async inserts, respectively. The default value is true.
  Keep in mind this setting is added since the exporter now sets it to default.
  Async insert and its related settings can still be defined in endpoint and connection_params, which take priority over the new config option.

• clickhouseexporter: Add AggregationTemporality column to histogram and exponential histogram tables. Rename AggTemp column to AggregationTemporality in sum table. (#33424)
  It's a breaking change. users who upgrade to the latest version need to alter the Clickhouse table:

  ALTER TABLE otel_metrics_exponential_histogram ADD COLUMN AggregationTemporality Int32 CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_histogram ADD COLUMN AggregationTemporality Int32 CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_sum RENAME COLUMN AggTemp TO AggregationTemporality;

• exporter/clickhouse: Remove deprecated ttl_days config option, use ttl instead. (#33648)

  All splitting is behaviorally, the same. However, the resource routingID now uses the internal/exp/metrics/identity package to generate the load balancing key, instead of bespoke code. This means that when upgrading to this version your routes for specific metric groupings could change. However, this will be stable and all future metrics will follow the new routing

• receiver/mongodbreceiver: Add server.address and server.port resource attributes to MongoDB receiver. (#32810, #32350)
