signalfx/splunk-otel-collector v0.134.0

on GitHub

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.134.0
and the opentelemetry-collector-contrib v0.134.0 releases where appropriate.

🛑 Breaking changes 🛑

• (Splunk) configconverter: Remove normalize_gcp config converter (#6695)
  Upgrades from below v0.69.0 to v0.69.0 or above will no longer handle GCP config conversion.
  This is relevant for the resourcedetection processor, if a user was using the gce or
  gke detectors. Please refer to the
  upgrade guide
  for information on how to resolve.
• (Splunk, Contrib) routingprocessor: Remove deprecated component routingprocessor (#6634, #19739)
  Please use the routing connector instead.
• (Contrib) pkg/ottl: Keep the original map and continue processing keys if an error is encountered when calling an optional replacement function in replace_all_patterns. (#42359)

🚀 New components 🚀

• (Splunk) dockerstatsreceiver: Added the docker_stats receiver to the Splunk distribution of the OpenTelemetry Collector. (#6621)
  The docker_stats receiver
  queries the local Docker daemon's container stats API for all desired running containers on a configured interval.
  These stats are for container resource usage of cpu, memory, network, and the blkio controller.

💡 Enhancements 💡

• (Splunk) zpagesextension: Expose collector configuration via the zpages extension. (#6595)
  The endpoint exposed by the zpages extension is now configured expose the collector configurations
  (initial and effective) via the expvarz endpoint, e.g.: http://localhost:55679/debug/expvarz
  for the default zpages configuration. The endpoint contents is a JSON map in which the keys
  splunk.config.initial and splunk.config.effective contains a string with the respective
  configuration YAML. This will be the replacement when the config debug endpoint is removed
  in the future. The expvarz endpoint can be disabled directly on the configuration file
  or via the command-line flags by use of --set=extensions.zpages.expvar.enabled=false
  when using the default configurations of the Splunk collector.
• (Splunk) logs: Added a new optional environment variable to the default Linux logs configuration file (#6656)
  The new variable is SPLUNK_FILE_STORAGE_EXTENSION_PATH, which is used for
  setting where the filelog receiver's checkpoint files are stored. The default value
  for this flag is /var/lib/otelcol/filelogs. This is only relevant for the
  logs_config_linux.yaml configuration file at this time.
• (Splunk) instrumentation: Update splunk-otel-javaagent to v2.19.0 (#6635)
• (Core) pdata: Add custom grpc/encoding that replaces proto and calls into the custom marshal/unmarshal logic in pdata. (#13631)
  This change should not affect other gRPC calls since it fallbacks to the default grpc/proto encoding if requests are not pdata/otlp requests.
• (Core) pdata: Avoid copying the pcommon.Map when same origin (#13731)
  This is a very large improvement if using OTTL with map functions since it will avoid a map copy.
• (Core) exporterhelper: Respect num_consumers when batching and partitioning are enabled. (#13607)
• (Core) otlphttpexporter: Add profiles_endpoint configuration option to allow custom endpoint for profiles data export (#13504)
  The profiles_endpoint configuration follows the same pattern as traces_endpoint, metrics_endpoint, and logs_endpoint.
  When specified, profiles data will be sent to the custom URL instead of the default {endpoint}/v1development/profiles.
• (Core) pdata: Add support for local memory pooling for data objects. (#13678)
  This is still an early experimental (alpha) feature. Do not recommended to be used production. To enable use "--featuregate=+pdata.useProtoPooling"
• (Core) pdata: Optimize CopyTo messages to avoid any copy when same source and destination (#13680)
• (Core) receiverhelper: New feature flag to make receiverhelper distinguish internal vs. downstream errors using new otelcol_receiver_failed_x and otelcol_receiver_requests metrics (#12207, #12802)
  This is a breaking change for the semantics of the otelcol_receiver_refused_metric_points, otelcol_receiver_refused_log_records and otelcol_receiver_refused_spans metrics.
  These new metrics and semantics are enabled through the receiverhelper.newReceiverMetrics feature gate.
• (Core) debugexporter: Add support for entity references in debug exporter output (#13324)
• (Core) pdata: Fix unnecessary allocation of a new state when adding new values to pcommon.Map (#13634)
• (Core) service: Implement refcounting for pipeline data owned memory. (#13631)
  This feature is protected by --featuregate=+pdata.useProtoPooling.
• (Core) service: Add a debug-level log message when a consumer returns an error. (#13357)
• (Core) xpdata: Optimize xpdata/context for persistent queue when only one value for key (#13636)
• (Core) otlpreceiver: Log the listening addresses of the receiver, rather than the configured endpoints. (#13654)
• (Core) pdata: Use the newly added proto marshaler/unmarshaler for the official proto Marshaler/Unmarshaler (#13637)
  If any problems observed with this consider to disable the featuregate --feature-gates=-pdata.useCustomProtoEncoding

• (Core) configtls: Enable X25519MLKEM768 as per draft-ietf-tls-ecdhe-mlkem (#13670)
• (Contrib) k8sclusterreceiver: Add optional experimental k8s.container.status.state metric (#32457)
• (Contrib) kafkareceiver: Add on_permanent_error option to message_marking configuration. (#41333)
• (Contrib) filelogreceiver: Move filelog.decompressFingerprint feature gate to beta stage (#42189)
• (Contrib) httpcheckreceiver: Add request body to http requests (#41325)
  The httpcheckreceiver can be configured to send a request body to the target endpoint.
• (Contrib) tailsamplingprocessor: Optimize telemetry collection in tailsamplingprocessor (#41888)
• (Contrib) oracledbreceiver: Add support for Oracle DB receiver to read session action as trace context. (#41878)
• (Contrib) oracledbreceiver: Removing the toLowercase conversion on sql text in top_query payload. Also, adding child_address into the query_samples payload. (#37478)
• (Contrib) prometheusreceiver: Remove temporary fix for metric name validation, fix upstream resolved (#42004)
• (Contrib) tailsamplingprocessor: Add a new option to block on num traces overflow. (#41546)
• (Contrib) httpcheckreceiver: Add response body validation (#41325)
  The httpcheckreceiver now supports validating the response body using a few approaches.
  String matching, JSON path matching, size ranges, and regex matching are supported.
• (Contrib) httpcheckreceiver: Fix race for timing of request steps (#42042)
  The httpcheckreceiver uses atomic operations to track the timing of request steps to avoid race conditions.
• (Contrib) pkg/ottl: Avoid multiple copies of the Map in replace_all_patterns. (#42359)
• (Contrib) kafkareceiver: Add profiles support (#41479)
• (Contrib) pkg/ottl: Remove unnecessary Value initialization when setting an attribute/body (#42335, #42362)
• (Contrib) pkg/ottl: Add an Index(target, value) OTTL function which returns the index of the first occurrence of value in target. (#40351)
• (Contrib) pkg/stanza: add sanitize_utf8 operator to replace invalid UTF-8 characters. (#42028)

🧰 Bug fixes 🧰

• (Core) exporterhelper: Prevent uncontrolled goroutines in batcher due to a incorrect worker pool behaviour. (#13689)
• (Core) service: Ensure the insecure configuration is accounted for when normalizing the endpoint. (#13691)
• (Core) configoptional: Allow validating nested types (#13579)
  configoptional.Optional now implements xconfmap.Validator
• (Core) batchprocessor: Fix UB in batch processor when trying to read bytes size after adding request to pipeline (#13698)
  This bug only happens id detailed metrics are enabled and also an async (sending queue enabled) exporter that mutates data is configure.
• (Core) pdata: Correctly parse OTLP payloads containing non-packed repeated primitive fields (#13727, #13730)
  This bug prevented the Collector from ingesting most Histogram, ExponentialHistogram,
  and Profile payloads.
• (Contrib) k8sattributesprocessor: Allow service.namespace to be used in rules and fix docs (#40859)
• (Contrib) tailsamplingprocessor: Fix a race condition in the tailsampling processor that could cause traces to be dropped prematurely. (#41656)
• (Contrib) sqlserverreceiver: Fix memory leak from top queries and query samples features (#42302)
  The issue was caused by the misuse of the obfuscate library.
