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.

🚩 Deprecations 🚩

• (Core) configgrpc: Deprecate GRPCClientSettings, use ClientConfig instead (#6767)

💡 Enhancements 💡

• (Splunk) Add a resource attribute to internal metrics to track discovery usage (#4323)
• (Splunk) Create a multi-architecture Windows docker image for the collector (#4296)
• (Splunk) Bump splunk-otel-javaagent to v1.30.2 (#4300)
• (Core) mdatagen: Add a generated test that checks the config struct using componenttest.CheckConfigStruct (#9438)
• (Core) component: Add component.UseLocalHostAsDefaultHost feature gate that changes default endpoints from 0.0.0.0 to localhost (#8510)
  The only component in this repository affected by this is the OTLP receiver.
• (Core) confighttp: Add support of Host header (#9395)
• (Core) mdatagen: Remove use of ReportFatalError in generated tests (#9439)
• (Contrib) receiver/journald: add a new config option "all" that turns on full output from journalctl, including lines that are too long. (#30920)
• (Contrib) pkg/stanza: Add support in a header configuration for json array parser. (#30321)
• (Contrib) awss3exporter: Add the ability to export trace/log/metrics in OTLP ProtoBuf format. (#30682)
• (Contrib) dockerobserver: Upgrading Docker API version default from 1.22 to 1.24 (#30900)
• (Contrib) filterprocessor: move metrics from OpenCensus to OpenTelemetry (#30736)
• (Contrib) groupbyattrsprocessor: move metrics from OpenCensus to OpenTelemetry (#30763)
• (Contrib) loadbalancingexporter: Optimize metrics and traces export (#30141)
• (Contrib) all: Add component.UseLocalHostAsDefaultHost feature gate that changes default endpoints from 0.0.0.0 to localhost (#30702)
  This change affects the following components:
  • extension/health_check
  • receiver/jaeger
  • receiver/sapm
  • receiver/signalfx
  • receiver/splunk_hec
  • receiver/zipkin
• (Contrib) processor/resourcedetectionprocessor: Detect Azure cluster name from IMDS metadata (#26794)
• (Contrib) processor/transform: Add copy_metric function to allow duplicating a metric (#30846)

🧰 Bug fixes 🧰

• (Splunk) Fixes the value of a default environment variable used by Windows msi. (#4361)
• (Core) service: fix opencensus bridge configuration in periodic readers (#9361)
• (Core) otlpreceiver: Fix goroutine leak when GRPC server is started but HTTP server is unsuccessful (#9165)
• (Core) otlpexporter: PartialSuccess is treated as success, logged as warning. (#9243)
• (Contrib) basicauthextension: Accept empty usernames. (#30470)
  Per https://datatracker.ietf.org/doc/html/rfc2617#section-2, username and password may be empty strings ("").
  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 🛑

• (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. |

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.

  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.

v0.91.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.91.0 and the opentelemetry-collector-contrib v0.91.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) Node.js Auto Instrumentation:
  • The NODE_OPTIONS environment variable in the default config file has been updated to load the Node.js SDK from an absolute path (/usr/lib/splunk-instrumentation/splunk-otel-js/node_modules/@splunk/otel/instrument).
  • The Linux installer script now installs the Node.js SDK to /usr/lib/splunk-instrumentation/splunk-otel-js instead of globally.
  • The --npm-command Linux installer script option is no longer supported. To specify a custom path to npm, use the --npm-path <path> option.
• (Splunk) translatesfx: Remove translatesfx (#4028)
• (Splunk) collectd/elasticsearch: Remove collectd/elasticsearch monitor (#3997)

🚩 Deprecations 🚩

• (Contrib) statsdreceiver: Add support for 'simple' tags that do not have a defined value, to accommodate DogStatsD metrics that may utilize these. (#29012)
  This functionality is gated behind a new enable_simple_tags config boolean, as it is not part of the StatsD spec.
• (Core) service: add resource attributes as labels to otel metrics to ensures backwards compatibility with OpenCensus metrics. (#9029)
• (Core) config/confighttp: Exposes http/2 transport settings to enable health check and workaround golang http/2 issue golang/go#59690 (#9022)

🧰 Bug fixes 🧰

• (Splunk) migratecheckpoint: Migrating offsets from SCK to SCK-Otel doesn't work. This is because of incorrect keys we use to populate the boltdb cache. (#3879)
• (Contrib) connector/spanmetrics: Fix memory leak when the cumulative temporality is used. (#27654)
• (Contrib) splunkhecexporter: Do not send null event field values in HEC events. Replace null values with an empty string. (#29551)
• (Contrib) k8sobjectsreceiver: fix k8sobjects receiver fails when some unrelated Kubernetes API is down (#29706)
• (Contrib) resourcedetectionprocessor: Change type of host.cpu.model.id and host.cpu.model.family from int to string. (#29025)
  Disable the processor.resourcedetection.hostCPUModelAndFamilyAsString feature gate to get the old behavior.
• (Contrib) filelogreceiver: Fix problem where checkpoints could be lost when collector is shutdown abruptly (#29609, #29491)
• (Contrib) pkg/stanza: Allow key_value_parser to parse values that contain the delimiter string. (#29629
• (Core) exporterhelper: fix missed metric aggregations (#9048)
  This ensures that context cancellation in the exporter doesn't interfere with metric aggregation. The OTel
  SDK currently returns if there's an error in the context used in Add. This means that if there's a
  cancelled context in an export, the metrics are now recorded.

v0.90.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.90.1 and the opentelemetry-collector-contrib v0.90.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Core) service: To remain backwards compatible w/ the metrics generated today, otel generated metrics will be generated without the _total suffix (#7454)
• (Core) service: use WithNamespace instead of WrapRegistererWithPrefix (#8988)
  Using this functionality in the otel prom exporter fixes a bug where the
  target_info was prefixed as otelcol_target_info previously.

🚩 Deprecations 🚩

• (Splunk) Deprecate collectd/marathon (#3992)
• (Splunk) Add deprecation notice to collectd/etcd (use etcd instead) (#3990)
• (Splunk) Mark translatesfx as deprecated (#3984)

💡 Enhancements 💡

• (Splunk) mysqlreceiver: Add mysqlreceiver to the Splunk distribution (#3989)
• (Core) exporter/debug: Change default verbosity from normal to basic (#8844)
  This change has currently no effect, as basic and normal verbosity share the same behavior. This might change in the future though, with the normal verbosity being more verbose than it currently is (see open-telemetry/opentelemetry-collector#7806). This is why we are changing the default to basic, which is expected to stay at the current level of verbosity (one line per batch).
• (Core) exporterhelper: Fix shutdown logic in persistent queue to not require consumers to be closed first (#8899)
• (Core) confighttp: Support proxy configuration field in all exporters that support confighttp (#5761)
• (Contrib) resourcedetectionprocessor: Add k8s cluster name detection when running in EKS (#26794)
• (Contrib) pkg/ottl: Add new IsDouble function to facilitate type checking. (#27895)
• (Contrib) mysqlreceiver: expose tls in mysqlreceiver (#29269)
  If tls is not set, the default is to disable TLS connections.
• (Contrib) processor/transform: Convert between sum and gauge in metric context when alpha feature gate processor.transform.ConvertBetweenSumAndGaugeMetricContext enabled (#20773)
• (Contrib) receiver/mongodbatlasreceiver: adds project config to mongodbatlas metrics to filter by project name and clusters. (#28865)
• (Contrib) pkg/stanza: Add "namedpipe" operator. (#27234)
• (Contrib) pkg/resourcetotelemetry: Do not clone data in pkg/resourcetotelemetry by default (#29327)
  The resulting consumer will be marked as MutatesData instead
• (Contrib) pkg/stanza: Improve performance by not calling decode when nop encoding is defined (#28899)
• (Contrib) receivercreator: Added support for discovery of endpoints based on K8s services (#29022)
  By discovering endpoints based on K8s services, a dynamic probing of K8s service leveraging for example the httpcheckreceiver get enabled
• (Contrib) signalfxexporter: change default timeout to 10 seconds (#29436)
• (Contrib) hostmetricsreceiver: Add optional Linux-only metric system.linux.memory.available (#7417)
  This is an alternative to system.memory.usage metric with state=free.
  Linux starting from 3.14 exports "available" memory. It takes "free" memory as a baseline, and then factors in kernel-specific values.
  This is supposed to be more accurate than just "free" memory.
  For reference, see the calculations here.
  See also MemAvailable in /proc/meminfo.

🧰 Bug fixes 🧰

• (Splunk) cmd/otelcol: Fix the code detecting if the collector is running as a service on Windows. The fix should make
