on GitHub

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.120.0 and the opentelemetry-collector-contrib v0.120.1 releases where appropriate.

🛑 Breaking changes 🛑

• (Contrib) receiver/prometheus: Prometheus receiver now uses scrapers in Prometheus 3.0. (#36873)
  There are a number of breaking changes in Prometheus 3.0. Learn more about those changes and migration guide on https://prometheus.io/docs/prometheus/latest/migration/.
• (Contrib) activedirectorydsreceiver: Fixed typo in the attribute distingushed_names, renaming it to distinguished_names. (#37606)
• (Contrib) receiver/hostmetrics: Remove receiver.hostmetrics.normalizeProcessCPUUtilization feature gate (#34763)
• (Contrib) tailsamplingprocessor: Fix the decision timer metric to capture longer latencies beyond 50ms. (#37722)
  This changes the unit of the decision timer metric from microseconds to milliseconds.
• (Contrib) routingconnector: Remove match_once configuration parameter. (#36824)
• (Core) service: Align component logger attributes with those defined in RFC (#12217)
  See Pipeline Component Telemetry RFC

💡 Enhancements 💡

• (Splunk) Make Windows TA agnostic to Powershell ExecutionPolicy (#5935)
• (Contrib) processor/transformprocessor: Add support for global conditions and error mode overrides. (#29017)
  Global conditions are now available for context-inferred structured configurations, allowing the use of fully
  qualified paths. Additionally, a new configuration key called error_mode has been added to the context statements group.
  This key determines how the processor reacts to errors that occur while processing that specific group of statements.
  When provided, it overrides the top-level error mode, offering more granular control over error handling.
• (Contrib) pkg/stanza: Allow users to configure initial buffer size (#37786)
• (Contrib) vcenterreceiver: Adds three more vCenter virtual machine performance metrics (#37488)
• (Contrib) k8sclusterreceiver: Adds new descriptive attributes/metadata to the k8s.namespace and the container entity emitted from k8sclusterreceiver. (#37580)
  • Adds the following attributes to k8s.namespace entity:
    • k8s.namespace.phase: The phase of a namespace indicates where the namespace is in its lifecycle. E.g. 'active', 'terminating'
    • k8s.namespace.creation_timestamp: The time when the namespace object was created.
  • Adds the following attributes to container entity:
    • container.creation_timestamp: The time when the container was started. Only available if container is either in 'running' or 'terminated' state.
• (Contrib) splunkenterprisereceiver: Added a new splunk.health metric. (#36695)
• (Contrib) resourcedetectionprocessor: add the Dynatrace detector to the resource detection processor (#37577)
• (Contrib) extension/oauth2clientauth: Add expiry_buffer config to oauth2client extension, allowing token refresh before expiration with a default buffer of 5 minutes. (#35148)
  • Prevents authentication failures by refreshing the token early.
  • The default expiry buffer is set to 5 minutes, and users can adjust it as needed.
• (Contrib) googlecloudpubsubreceiver: Turn noisy warn log about Pub/Sub servers into debug, and turn the reset count into a metric (#37571)
  The receiver uses the Google Cloud Pub/Sub StreamingPull API and keeps a open connection. The Pub/Sub servers
  recurrently close the connection after a time period to avoid a long-running sticky connection. Before the
  receiver logged warn log lines everytime this happened. These log lines are moved to debug so that fleets with
  lots of collectors with the receiver don't span logs at warn level. To keep track of the resets, whenever a
  connection reset happens a otelcol_receiver_googlecloudpubsub_stream_restarts metric is increased by one.
• (Contrib) processor/redaction: Introduce 'allowed_values' parameter for allowed values of attributes (#35840)
• (Contrib) routingconnector: Avoid unnecessary copy of the data in routing connector (#37946)
• (Contrib) awscontainerinsightreceiver: Add support for HOST_PROC environment variable in AWS Container Insight Receiver. (#35862)
• (Contrib) syslogreceiver: Support setting on_error config for syslog receiver. (#36906)
• (Contrib) processor/tailsampling: Adds support for optionally recording the policy (and any composite policy) associated with an inclusive tail processor sampling decision.
  This functionality is disabled by default, you can enable it by passing the following feature flag to the collector: +processor.tailsamplingprocessor.recordpolicy
  (#35180)
• (Contrib) tailsamplingprocessor: makes the numeric_attribute more flexible and allows to set only min_value or max_value, without the need to set both (#37328)
  This is useful to have simple configurations like these:

  {
    type: numeric_attribute,
    numeric_attribute: {
      key: http.status_code,
      min_value: 400
    }
  }
  

• (Core) otlpreceiver: Update stability for logs (#12335)
• (Core) exporterhelper: Implement sync disabled queue used when batching is enabled. (#12245)
• (Core) exporterhelper: Enable the new pull-based batcher in exporterhelper (#12291)
• (Core) exporterhelper: Update queue size after the element is done exported (#12399)
  After this change the active queue size will include elements in the process of being exported.
• (Core) otelcol: Add featuregate command to display information about available features (#11998)
  The featuregate command allows users to view detailed information about feature gates
  including their status, stage, and description.

🧰 Bug fixes 🧰

• (Contrib) azureeventhubreceiver: Fix bug where persisted offset would be ignored after restart (#37157)
• (Contrib) bearertokenauthextension: Load token lazily for gRPC AUTH to fix token refresh issue (#36749)
• (Contrib) k8sattributes: Fix bug where Filters.Labels failed with when the exists or not-exists operations were used. (#37913)
• (Contrib) prometheusreceiver: Start time metric adjuster now handles reset points correctly (#37717)
• (Contrib) awscontainerinsightreceiver: Fix race condition in shutdown of AWS Container Insight receiver (#37695)
• (Core) memorylimiter: Logger no longer attributes to single signal, pipeline, or component. (#12217)
• (Core) otlpreceiver: Logger no longer attributes to random signal when receiving multiple signals. (#12217)
• (Core) exporterhelper: Fix undefined behavior access to request after send to next component. This causes random memory access. (#12281)
• (Core) exporterhelper: Fix default batcher to correctly call all done callbacks exactly once (#12247)
• (Core) otlpreceiver: Fix OTLP http receiver to correctly set Retry-After (#12367)
• (Core) otlphttpexporter: Fix parsing logic for Retry-After in OTLP http protocol. (#12366)
  The value of Retry-After field can be either an HTTP-date or delay-seconds and the current logic only parsed delay-seconds.
