• elasticsearchexporter: Update OTel mapping mode for logs and metrics; Remove trace_flags (#34472)
  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
  • pull_request.state is now change.state
  • git.vendor.name is now vcs.vendor.name
    Metric Changes:
  • git.repository.count is now vcs.repository.count
  • git.repository.contributor.count is now vcs.repository.contributor.count
  • git.repository.branch.count is now vcs.repository.ref.count
  • git.repository.branch.time is now `vcs.repository.ref.time
  • git.repository.branch.commit.aheadby.count is now vcs.repository.ref.revisions_ahead
  • git.repository.branch.commit.behindby.count is now `vcs.repository.ref.revisions_behind

  • git.repository.pull_request.count is now vcs.change.count

• 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

🚀 New components 🚀

• exporter/doris: Add a new component for exporting logs, traces and metrics to Doris (#33479)

💡 Enhancements 💡

• geoipprocessor: Add a context configuration option to specify the IP address attribute telemetry location. (#34036)

🧰 Bug fixes 🧰

• tailsamplingprocessor: Update the policy value in metrics dimension value to be unique across multiple tail sampling components with the same policy name. (#34192)
  This change ensures that the policy value in the metrics exported by the tail sampling processor is unique across multiple tail sampling processors with the same policy name.

• datadogreceiver: add feature discovery (#34718)

• datadogconnector: Put back the otelcol_ prefix for Datadog internal metrics on trace and APM stats exporting (#34807)
  Recovers these metrics from an upstream breaking change. See open-telemetry/opentelemetry-collector#9759 and open-telemetry/opentelemetry-collector#10940.

• datadogexporter: Put back the otelcol_ prefix for Datadog internal metrics on trace and APM stats exporting (#34807)

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.

🚩 Deprecations 🚩

• k8sattributesprocessor: Deprecate extract.annotations.regex and extract.labels.regex config fields in favor of the ExtractPatterns function in the transform processor. The FieldExtractConfig.Regex parameter will be removed in version v0.111.0. (#25128)
  Deprecating of FieldExtractConfig.Regex parameter means that it is recommended to use the ExtractPatterns function from the transform processor instead. To convert your current configuration please check the ExtractPatterns function documentation. You should use the pattern parameter of ExtractPatterns instead of using the FieldExtractConfig.Regex parameter.

  It is an expected that when querying Windows Performance Counters the targeted instances may not be present.
  The receiver will no longer require the use of recreate_query to handle non-existing instances.
  As soon as the instances are available, the receiver will start collecting metrics for them.
  There won't be warning log messages when there are no matches for the configured instances.

• kafkareceiver: Add settings session_timeout and heartbeat_interval to Kafka Receiver for group management facilities (#28630)

v0.105.0

🛑 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/[email protected]/operator/helper#WriterOperator.Write
• vcenterreceiver: Enables various vCenter metrics that were disabled by default until v0.105 (#34022)
  The following metrics will be enabled by default "vcenter.host.network.packet.drop.rate",
  "vcenter.vm.cpu.readiness", "vcenter.host.cpu.capacity", and "vcenter.host.cpu.reserved".

🚩 Deprecations 🚩

💡 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)

• vcenterreceiver: Adds vCenter metrics at the datacenter level. (#33607)
  Introduces various datacenter metrics which work by aggregating stats from datastores, clusters, hosts, and VM's.

• processor/resource, processor/attributes: Add an option to extract value from a client address by specifying client.address value in the from_context field. (#34051)

• awss3receiver: Add support for retrieving logs and metrics to the AWS S3 Receiver. (#30750)

• receiver/azuremonitorreceiver: Add support for Managed Identity and Default Credential auth (#31268, #33584)

• 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.

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}.

🛑 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)

• vcenterreceiver: Drops support for vCenter 6.7 (#33607)

• all: Promote component.UseLocalHostAsDefaultHost feature gate to beta. This changes default endpoints from 0.0.0.0 to localhost (#30702)

  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)
  The new resource attributes are added to the MongoDB receiver to distinguish metrics coming from different MongoDB instances.

  • server.address: The address of the MongoDB host, enabled by default.

End User Changelog

🛑 Breaking changes 🛑

• cmd/opampsupervisor,extension/opamp: Upgrade the opamp-go library to v0.15.0 (#33416)
  With this change, UUIDv7 is recommended for the OpAMP extension's instance_uid field instead of ULID. ULIDs will continue to work, but may be displayed as UUIDs.
  The supervisor's persistent state (${storage_dir}/persistent_state.yaml) will need to be cleared to generate a new UUIDv7 instead of a ULID.
  This change may be incompatible with management servers using v0.14.0 of opamp-go.

• mongodbreceiver: Now only supports TCP connections (#32199)
  This fixes a bug where hosts had to explicitly set tcp as the transport type. The transport option has been removed.

• cmd/configschema: Removes the deprecated configschema command. This command will no longer be released or supported. (#33384)

• sqlserverreceiver: sqlserver.database.io.read_latency has been renamed to sqlserver.database.latency with a direction attribute. (#29865)

🚩 Deprecations 🚩

• healthcheckextension: Remove incorrect logic behind check_collector_pipeline config (#33469)
  This logic incorrectly set the pipeline to OK after waiting for enough callbacks from the
  opencensus library to be called. As this was broken, I'm removing it to remove the dependency
  on opencensus as well. Improvements will be available via healthcheckv2 extension.

• googlecloudspannerreceiver: Mark the component as unmaintained. If we don't find new maintainers, it will be deprecated and removed. (#32651)

• elasticsearchexporter: Add support for confighttp options, notably "auth". (#33367)
  Add support for confighttp and related configuration settings, such as "auth".
  This change also means that the Elasticsearch URL may be specified as "endpoint",
  like the otlphttp exporter.

• elasticsearchexporter: Check that endpoints are valid URLs during config validation. (#33350)
  Check that endpoints are valid URLs during config validation so that
  an invalid endpoint causes a fatal error during startup, rather than
  leading to a persistent runtime error.

• opampsupervisor: Add config validation for the supervisor config (#32843)

• statsdreceiver: Added received/accepted/refused metrics (#24278)

• filelogreceiver: Add support for gzip compressed log files (#2328)

• confmap/provider/secretsmanagerprovider: Add support for JSON formatted secrets in secretsmanagerprovider confmap (#32143)
  The secretsmanagerprovider confmap will now allow to get secret by a json key if the secret value is json.

• healthcheckv2extension: Add shared aggregation logic for status events. (#26661)

• tailsamplingprocessor: Simple LRU Decision Cache for "keep" decisions (#31583)

• processor/tailsampling: Migrates internal telemetry to OpenTelemetry SDK via mdatagen (#31581)
  The metric names and their properties, such as bucket boundaries for histograms, were kept like before, to keep backwards compatibility.

• kafka: Added disable_fast_negotiation configuration option for Kafka Kerberos authentication, allowing the disabling of PA-FX-FAST negotiation. (#26345)

• pkg/ottl: Added keep_matching_keys function to allow dropping all keys from a map that don't match the pattern. (#32989)

• pkg/ottl: Introducing Uri converter parsing URI string into SemConv (#32433)

• probabilisticsamplerprocessor: Add Proportional and Equalizing sampling modes (#31918)
  Both the existing hash_seed mode and the two new modes use OTEP 235 semantic conventions to encode sampling probability.

• prometheusreceiver: Resource attributes produced by the prometheus receiver now include stable semantic conventions for server and url. (#32814)
  To migrate from the legacy net.host.name, net.host.port, and http.scheme resource attributes, |
  migrate to server.address, server.port, and url.scheme, and then |
  set the receiver.prometheus.removeLegacyResourceAttributes feature gate.

• datadogexporter: The Datadog Exporter now supports the proxy_url parameter to configure an HTTP proxy to use when sending telemetry to Datadog. (#33316)

• spanmetrics: Produce delta temporality span metrics with StartTimeUnixNano and TimeUnixNano values representing an uninterrupted series (#31671, #30688)
  This allows producing delta span metrics instead of the more memory-intensive cumulative metrics, specifically when a downstream component can convert the delta metrics to cumulative.

• sqlserverreceiver: Add support for more Database IO metrics (#29865)
  The following metrics have been added:

  • sqlserver.database.latency
  • sqlserver.database.io
  • sqlserver.database.operations

• cmd/opampsupervisor: Receive and report effective config to the OpAMP server (#30622)

• processor/transform: Add transform.flatten.logs featuregate to give each log record a distinct resource and scope. (#32080)
  This option is useful when applying transformations which alter the resource or scope. e.g. set(resource.attributes["to"], attributes["from"]), which may otherwise result in unexpected behavior. Using this option typically incurs a performance penalty as the processor must compute many hashes and create copies of resource and scope information for every log record.

• receiver/windowsperfcounters: Counter configuration now supports recreating the underlying performance query at scrape time. (#32798)

🧰 Bug fixes 🧰

• filelogreceiver: Container parser should add k8s metadata as resource attributes and not as log record attributes (#33341)

🛑 Breaking changes 🛑

• k8sattributesprocessor: Move k8sattr.rfc3339 feature gate to stable. (#33304)

• extension/opamp: Redact all values in the effective config (#33267)
  All values will be treated as if they are a configopaque.String type. This will
  be changed once the Collector APIs are updated to unmarshal the config while
  only redacting actual configopaque.String-typed values.

  The exception to redaction is the service::pipelines section, which is useful
  for debugging and does not contain any configopaque.String values.

• extension/filestorage: Replace path-unsafe characters in component names (#3148)
  The feature gate extension.filestorage.replaceUnsafeCharacters is now removed.

• awsxrayexporter: change x-ray exporter's translator to make "." split annotation pass as-is (#32694, #31732)
  This change make below change to beta stage for feature gate 'exporter.xray.allowDot'，this change will let the change mention below enable by default | In the past, X-Ray doesn’t support “.”. So we have a translator in x-ray export to translates it to “_” before sending traces to X-Ray Service. | To match otel naming style, x-ray service team decide to change their service to support both "." type and "" type of naming. In this case the translator that translate "." to "" is no-longer needed. This PR change the way this translator work | X-Ray PMs agree on rolling out this change by using feature-gate

🛑 Breaking changes 🛑

• receiver/hostmetrics: enable feature gate receiver.hostmetrics.normalizeProcessCPUUtilization (#31368)
  This changes the value of the metric process.cpu.utilization by dividing it by the number of CPU cores.
  For example, if a process is using 2 CPU cores on a 16-core machine,
  the value of this metric was previously 2, but now it will be 0.125.

• exporter/kafkaexporter: Enable setting message topics using resource attributes. (#31178)

• exporter/datadog: Introduces the Datadog Agent logs pipeline for exporting logs to Datadog under the "exporter.datadogexporter.UseLogsAgentExporter" feature gate. (#32327)

• elasticsearchexporter: Add retry.retry_on_status config (#32584)
  Previously, the status codes that trigger retries were hardcoded to be 429, 500, 502, 503, 504.
  It is now configurable using retry.retry_on_status, and defaults to [429, 500, 502, 503, 504] to avoid a breaking change.
  To avoid duplicates, it is recommended to configure retry.retry_on_status to [429], which would be the default in a future version.

• exporter/splunkhec: add experimental exporter batcher config (#32545)

• ptracetest: Add support for ignore scope span instrumentation scope information (#32852)

• sqlserverreceiver: Enable direct connection to SQL Server (#30297)
  Directly connecting to SQL Server will enable the receiver to gather more metrics
  for observing the SQL Server instance. The first metric added with this update is
  sqlserver.database.io.read_latency.

• connector/datadog: The Datadog connector now has a config option to identify top-level spans by span kind. This new logic can be enabled by setting traces::compute_top_level_by_span_kind to true in the Datadog connector config. Default is false. (#32005)
  traces::compute_top_level_by_span_kind needs to be enabled in both the Datadog connector and Datadog exporter configs if both components are being used.
  With this new logic, root spans and spans with a server or consumer span.kind will be marked as top-level. Additionally, spans with a client or producer span.kind will have stats computed.
  Enabling this config option may increase the number of spans that generate trace metrics, and may change which spans appear as top-level in Datadog.

• exporter/datadog: The Datadog exporter now has a config option to identify top-level spans by span kind. This new logic can be enabled by setting traces::compute_top_level_by_span_kind to true in the Datadog exporter config. Default is false. (#32005)
