v0.115.0

🛑 Breaking changes 🛑

• (Splunk) Change default traces exporter to otlphttp exporter. (#5588).
  See the upgrade guidelines on how to change existing configs to replace SAPM exporter.
• (Core) Change all logged timestamps to ISO8601 (#10543).
  This makes log timestamps human-readable (as opposed to epoch seconds in
  scientific notation), but may break users trying to parse logged lines in the
  old format.
• (Contrib) k8sattributesprocessor: Move k8sattr.fieldExtractConfigRegex.disallow feature gate to Beta. (#25128)
  Disable the k8sattr.fieldExtractConfigRegex.disallow feature gate to get the old behavior.

🚀 New components 🚀

• (Splunk) Add filestats receiver (#5229)
• (Splunk) Add iis receiver (#5717)

💡 Enhancements 💡

• (Splunk) Automatic Discovery:
  • Switch bundled NGINX discovery to create OpenTelemetry NGINX receiver instead of the Smart Agent NGINX monitor (#5689)
• (Splunk) Expose internal metrics at default localhost:8888 address instead of ${SPLUNK_LISTEN_INTERFACE}:8888 (#5706)
  This can be changed in service::telemetry::metrics section:

  service:
    telemetry:
      metrics:
        readers:
          - pull:
              exporter:
                prometheus:
                  host: localhost
                  port: 8888

  This also removes a warning about deprecated service::telemetry::metrics::address.
• (Core) exporterqueue: Introduce a feature gate exporter.UsePullingBasedExporterQueueBatcher to use the new pulling model in exporter queue batching. (#8122, #10368)
  If both queuing and batching is enabled for exporter, we now use a pulling model instead of a
  pushing model. num_consumer in queue configuration is now used to specify the maximum number of
  concurrent workers that are sending out the request.
• (Core) service: Add support for ca certificates in telemetry metrics otlp grpc exporter (#11633)
  Before this change the Certificate value in config was silently ignored.
• (Contrib) postgresqlreceiver: Added new postgresql metrics to achieve parity with Telegraf (#36528)
• (Contrib) loadbalancingexporter: Adding sending_queue, retry_on_failure and timeout settings to loadbalancing exporter configuration (#35378)
  When switching to top-level sending_queue configuration - users should carefully review queue size
  In some rare cases setting top-level queue size to n*queueSize might be not enough to prevent data loss
• (Contrib) routingconnector: Add abiilty to route by 'datapoint' context (#36523)
• (Contrib) signalfxreceiver: Follow receiver contract based on type of error (#5909)
  Use 503 error code for retryable and 400 error code for not-retryable errors instead of responding with a 500 unconditionally.

🧰 Bug fixes 🧰

• (Core) service: ensure OTLP emitted logs respect severity (#11718)
• (Core) featuregate: Fix an unfriendly display message runtime error when feature gate is used to display command line usage. (#11651)
• (Contrib) exporter/pulsarexporter: Change configuration option map_connections_per_broker, rename to max_connections_per_broker. (#36579)
• (Contrib) processor/k8sattribute: fixes parsing of k8s image names to support images with tags and digests. (#36131)
• (Contrib) loadbalancingexporter: The k8sresolver in loadbalancingexporter was triggering exporter churn in the way the change event was handled. (#35658)
• (Contrib) vcenterreceiver: The existing code did not honor TLS settings beyond 'insecure'. All TLS client config should now be honored. (#36482)
