🚀 New components 🚀

• (Splunk) Add chrony receiver (#5535)

💡 Enhancements 💡

• (Splunk) Update Python to 3.13.0 (5552)
• (Core) confighttp: Adding support for lz4 compression into the project (#9128)
• (Core) service: Hide profiles support behind a feature gate while it remains alpha. (#11477)
• (Core) exporterhelper: Retry sender will fail fast when the context timeout is shorter than the next retry interval. (#11183)
• (Contrib) azureeventshubreceiver: Updates the Azure Event Hub receiver to use the new Resource Logs translator. (#35357)
• (Contrib) pkg/ottl: Add ConvertAttributesToElementsXML Converter (#35328)
• (Contrib) azureblobreceiver: adds support for using azidentity default auth, enabling the use of Azure Managed Identities, e.g. Workload Identities on AKS (#35636)
  This change allows to use authentication type "default", which makes the receiver use azidentity default Credentials,
  which automatically picks up, identities assigned to e.g. a container or a VirtualMachine
• (Contrib) k8sobserver: Emit endpoint per Pod's container (#35491)
• (Contrib) mongodbreceiver: Add support for MongoDB direct connection (#35427)
• (Contrib) chronyreceiver: Move chronyreceiver to beta (#35913)
• (Contrib) pkg/ottl: Parsing invalid statements and conditions now prints all errors instead of just the first one found. (#35728)
• (Contrib) pkg/ottl: Add ParseSimplifiedXML Converter (#35421)
• (Contrib) routingconnector: Allow routing based on OTTL Conditions (#35731)
  Each route must contain either a statement or a condition.
• (Contrib) sapmreceiver: Respond 503 on non-permanent and 400 on permanent errors (#35300)
• (Contrib) hostmetricsreceiver: Use HOST_PROC_MOUNTINFO as part of configuration instead of environment variable (#35504)
• (Contrib) pkg/ottl: Add ConvertTextToElements Converter (#35364)

🧰 Bug fixes 🧰

• (Core) processorhelper: Fix issue where in/out parameters were not recorded when error was returned from consumer. (#11351)
• (Contrib) metricstransform: The previously removed functionality of aggregating against an empty label set is restored. (#34430)
• (Contrib) filelogreceiver: Supports add_metadata_from_filepath for Windows filepaths (#35558)
• (Contrib) 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.
• (Contrib) kafkareceiver: Fixes issue causing kafkareceiver to block during Shutdown(). (#30789)
• (Contrib) 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.
• (Contrib) pkg/ottl: Allow indexing string slice type (#29441)
• (Contrib) mysqlreceiver: Add replica metric support for versions of MySQL earlier than 8.0.22. (#35217)
• (Contrib) stanza/input/windows: Close remote session while resubscribing (#35577)
• (Contrib) `...

• (Contrib) file_storage: provide a new option to the user to create a directory on start (#34939)
• (Contrib) headersetterextension: adding default_value config. default_value config item applied in case context value is empty. (#34412)
• (Contrib) kafkaexporter: Add support for encoding extensions in the Kafka exporter. This change adds support for encoding extensions in the Kafka exporter. Loading extensions takes precedence over the internally supported encodings. (#34384)
• (Contrib) kafkareceiver: Add support for otlp_json encoding to Kafka receiver. The payload is deserialized into OpenTelemetry traces using JSON format. This encoding allows the Kafka receiver to handle trace data in JSON format, enabling integration with systems that export traces as JSON-encoded data. (#33627)

• (Contrib) splunkenterprise: Fix a flaky search related to iops metrics. (#35081)
• (Contrib) azuremonitorexporter: fix issue for property endpoint is ignored when using instrumentation_key (#33971)
• (Contrib) groupbytraceprocessor: Ensure processor_groupbytrace_incomplete_releases metric has a unit. (#35221)
• (Contrib) deltatocumulative: do not drop gauges and summaries. Gauges and Summaries are no longer dropped from processor output. Instead, they are passed through as-is. (#35284)
• (Contrib) pkg/stanza: Do not get formatted message for Windows events without an event provider. Attempting to get the formatted message for Windows events without an event provider can result in an error being logged. This change ensures that the formatted message is not retrieved for such events. (#35135)
• (Contrib) signalfxexporter: Ensure token is not sent through for event data (#35154)

v0.109.0

🛑 Breaking changes 🛑

• (Splunk) Update Python to 3.12.5 in the Smart Agent bundle for Linux and Windows. Check What’s New In Python 3.12 for details. (#5298)
• (Contrib) spanmetricsconnector: Improve consistency between metrics generated by spanmetricsconnector. Added traces.span.metrics as default namespace (#33227
  Default namespace for the generated metrics is traces.span.metrics now. | The deprecated metrics are: calls, duration and events. | The feature flag connector.spanmetrics.legacyLatencyMetricNames was added to revert the behavior.
• (Contrib) ottl: Remove tracing from OTTL due to performance concerns (#34910

🚀 New components 🚀

• (Splunk) Add apachespark receiver (#5318)
• (Splunk) Add nop receiver and exporter (#5355)

💡 Enhancements 💡

• (Splunk) Apache Web Server Auto Discovery: set the default discovered endpoint to match the OpenTelemetry apachereceiver default: http://endpoint/server-status?auto (#5353)
  If the collector is running as a process on the host OS and the Apache Web Server is in a Docker container add --set=splunk.discovery.extensions.docker_observer.config.use_host_bindings=true to the command-line arguments for the discovery to create the correct endpoint.
• (Splunk) Introduce continuous service discovery mode. This mode can be enabled with a feature gate by adding --feature-gates=splunk.continuousDiscovery command line argument. (#5363)
  The new mode does the following:
  • It allows discovering new services that were not available at the time of the collector startup. If discovery is
    successful, the metrics collection will be started.
  • Information about discovered services is being sent to Splunk Observability Cloud. The information will include
    instructions to complete discovery for particular services if the discovery was not successful out of the box.
• (Core) service: move useOtelWithSDKConfigurationForInternalTelemetry gate to beta (#11091)
• (Core) service: implement a no-op tracer provider that doesn't propagate the context (#11026)
  The no-op tracer provider supported by the SDK incurs a memory cost of propagating the context no matter
  what. This is not needed if tracing is not enabled in the Collector. This implementation of the no-op tracer
  provider removes the need to allocate memory when tracing is disabled.
• (Core) processor: Add incoming and outgoing counts for processors using processorhelper. (#10910)
  Any processor using the processorhelper package (this is most processors) will automatically report
  incoming and outgoing item counts. The new metrics are:
  • otelcol_processor_incoming_spans
  • otelcol_processor_outgoing_spans
  • otelcol_processor_incoming_metric_points
  • otelcol_processor_outgoing_metric_points
  • otelcol_processor_incoming_log_records
  • otelcol_processor_outgoing_log_records
• (Contrib) pkg/ottl: Added Decode() converter function (#32493
• (Contrib) filestorage: Add directory validation for compaction on-rebound (#35114
• (Contrib) windowseventlogreceiver: Avoid rendering the whole event to obtain the provider name (#34755
• (Contrib) splunkhecexporter: Drop empty log events (#34871
  Log records with no body are dropped by Splunk on reception as they contain no log message, albeit they may have attributes.
  This is in tune with the behavior of splunkhecreceiver, which refuses HEC events with no event (#19769
• (Contrib) transformprocessor: Support aggregating metrics based on their attribute values and substituting the values with a new value. (#16224
• (Contrib) kafkareceiver: Adds tunable fetch sizes to Kafka Receiver (#22741
  Adds the ability to tune the minumum, default and maximum fetch sizes for the Kafka Receiver
• (Contrib) kafkareceiver: Add support for encoding extensions in the Kafka receiver. (#33888
  This change adds support for encoding extensions in the Kafka receiver. Loading extensions takes precedence over the internally supported encodings.
• (Contrib) pkg/ottl: Add Sort function to sort array to ascending order or descending order (#34200
• (Contrib) redactionprocessor: Add support for logs and metrics (#34479
• (Contrib) spanmetricsconnector: Extract the getDimensionValue function as a common function. (#34627
• (Contrib) sqlqueryreceiver: Support populating log attributes from sql query (#24459

🧰 Bug fixes 🧰

• (Core) configgrpc: Change the value of max_recv_msg_size_mib from uint64 to int to avoid a case where misconfiguration caused an integer overflow. (#10948)

• (Contrib) splunkhecreceiver: Fix memory leak when the receiver is used for both metrics and logs at the same time (#34886
• (Contrib) pkg/stanza: Synchronize shutdown in stanza adapter (#31074
  Stanza-based receivers should now flush all data before shutting down
• (Contrib) sqlserverreceiver: Fix bug where metrics were being emitted with the wrong database name resource attribute (#35036
• (Contrib) signalfxexporter: Fix memory leak by re-organizing the exporter's functionality lifecycle (#32781
• (Contrib) otlpjsonconnector: Handle OTLPJSON unmarshal error (#34782
• (Contrib) mysqlreceiver: mysql client raise error when the TABLE_ROWS column is NULL, convert NULL to int64 (#34195
• (Contrib) pkg/stanza: An operator configured with silent errors shouldn't log errors while processing log entries. (#35008

v0.108.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.108.1 and the opentelemetry-collector-contrib v0.108.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Core) confmap: Mark confmap.strictlyTypedInput as stable (#10552)
• (Contrib) splunkhecexporter: The scope name has been updated from otelcol/splunkhec to github.com/open-telemetry/opentelemetry-collector-contrib/exporter/splunkhecexporter (#34710)
• (Contrib) transformprocessor: Promote processor.transform.ConvertBetweenSumAndGaugeMetricContext feature flag from alpha to beta (#34567)
• (Contrib) 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

  This replaces the feature gate service.noopTracerProvider introduced in v0.107.0
• (Contrib) awss3receiver: Enhance the logging of the AWS S3 Receiver in normal operation to make it easier for user to debug what is happening. (#30750)
• (Contrib) filelogreceiver: If acquire_fs_lock is true, attempt to acquire a shared lock before reading a file. (#34801)
  Unix only. If a lock cannot be acquired then the file will be ignored until the next poll cycle.
• (Contrib) solacereceiver: Updated the format for generated metrics. Included a receiver_name attribute that identifies the Solace receiver that generated the metrics (#34541)
• (Contrib) prometheusreceiver: Ensure Target Allocator's confighttp is used in the receiver's service discovery (#33370)
• (Contrib) metricstransformprocessor: Add scaling exponential histogram support (#29803)

• (Splunk) Auto Instrumentation for Linux (#5243)
  • Add support for the OTEL_LOGS_EXPORTER environment variable to libsplunk.so for system-wide auto instrumentation.
  • Linux installer script: Add the --logs-exporter <value> option:
    • Set the exporter for collected logs by all activated SDKs, for example otlp.
    • Set the value to none to disable collection and export of logs.
    • The value will be set to the OTEL_LOGS_EXPORTER environment variable.
    • Defaults to '' (empty), i.e. defer to the default OTEL_LOGS_EXPORTER value for each activated SDK.

🧰 Bug fixes 🧰

• (Core) batchprocessor: Update units for internal telemetry (#10652)
• (Core) confmap: Fix bug where an unset env var used with a non-string field resulted in a panic (#10950)
• (Core) service: Fix memory leaks during service package shutdown (#9165)
• (Core) confmap: Use string representation for field types where all primitive types are strings. (#10937)
• (Core) otelcol: Preserve internal representation when unmarshaling component configs (#10552)
• (Contrib) 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.
• (Contrib) prometheusreceiver: Group scraped metrics into resources created from job and instance label pairs (#34237)
  The receiver will now create a resource for each distinct job/instance label combination.
  In addition to the label/instance pairs detected from the scraped metrics, a resource representing the overall
  scrape configuration will be created. This additional resource will contain the scrape metrics, such as the number of scraped metrics, the scrape duration, etc.
• (Contrib) tailsamplingprocessor: Fix the behavior for numeric tag filters with inverse_match set to true. (#34296)

v0.106.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.106.0-v0.106.1 and the opentelemetry-collector-contrib v0.106.0-v0.106.1 releases where appropriate.

Note: Some core dependencies were incorrectly still set to v0.105.0 for this release.

🛑 Breaking changes 🛑

• (Core) 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.
• (Core) confighttp: Delete ClientConfig.CustomRoundTripper (#8627)
  Set (*http.Client).Transport on the *http.Client returned from ToClient to configure this.
• (Core) 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.
• (Core) component: Adds restrictions on the character set for component.ID name. (#10673)
• (Core) 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.
• (Core) 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.
• (Core) 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.
• (Contrib) vcenterreceiver: Enables various vCenter metrics that were disabled by default until v0.106.0 (#33607)
  The following metrics will be enabled by default "vcenter.datacenter.cluster.count", "vcenter.datacenter.vm.count", "vcenter.datacenter.datastore.count",
  "vcenter.datacenter.host.count", "vcenter.datacenter.disk.space", "vcenter.datacenter.cpu.limit", "vcenter.datacenter.memory.limit",
  "vcenter.resource_pool.memory.swapped", "vcenter.resource_pool.memory.ballooned", and "vcenter.resource_pool.memory.granted". The
  "resourcePoolMemoryUsageAttribute" has also been bumped up to release v.0.107.0
• (Contrib) 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.

v0.105.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.105.0 and the opentelemetry-collector-contrib v0.105.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) Don't expand environment variables starting with $$ in configuration files. This behavior was introduced
  in v0.42.0 to support a bug causing double expansion. $$ is treated as an escape sequence representing a literal
  $ character (#5134)
• (Core) service: add service.disableOpenCensusBridge feature gate which is enabled by default to remove the dependency on OpenCensus (#10414)
• (Core) 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.
  • Configurations using URI expansion (i.e. field: ${env:ENV}) for string-typed fields will use the value passed in ENV verbatim without intermediate type casting.
• (Contrib) 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
• (Contrib) 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 🚩

• (Splunk) Deprecate usage of bare environment variables and config sources in configuration files (#5153)
  • Use ${env:VAR} or ${VAR} instead of $VAR.
  • Use ${uri:selector} instead of $uri:selector, e.g. ${file:/path/to/file} instead of $file:/path/to/file.

• (Contrib) pkg/ottl: Added Hex() converter function (#31929)
• (Contrib) 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.
• (Contrib) 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.
• (Contrib) kubeletstatsreceiver: Add k8s.pod.memory.node.utilization and k8s.container.memory.node.utilization metrics (#33591)

• (Contrib) dockerobserver: Add hint to error when using float for api_version field (#34043)
• (Contrib) pkg/ottl: Emit traces for statement sequence executions to troubleshoot OTTL statements/conditions (#33433)
• (Contrib) 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.
• (Contrib) receiver/filelog: Add filelog.container.removeOriginalTimeField feature-flag for removing original time field (#33946)
• (Contrib) statsdreceiver: Allow configuring summary percentiles (#33701)
• (Contrib) pkg/stanza: Switch to faster json parser lib for container operator (#33929)
• (Contrib) telemetrygen: telemetrygen --rate flag changed from Int64 to Float64 (#33984)
• (Contrib) 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.
