v0.80.0

This Splunk OpenTelemetry Collector release includes changes from the opentelemetry-collector v0.80.0 and the opentelemetry-collector-contrib v0.80.0 releases where appropriate.

❗ Known Issues ❗

• (Contrib) k8sclusterreceiver: Missing node metrics for k8s.node.condition_out_of_disk, k8s.node.allocatable_pods and k8s.node.allocatable_hugepages-* (#23839)[https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/23839]

🛑 Breaking changes 🛑

• (Contrib) redisreceiver: Updates metric unit from no unit to Bytes. (#23454)
  Affected metrics can be found below.
  • redis.clients.max_input_buffer
  • redis.clients.max_output_buffer
  • redis.replication.backlog_first_byte_offset
  • redis.replication.offset
• (Splunk) Embed observer configuration in observer.discovery.yaml config mapping. This is only a breaking change if you have written your own custom discovery mode observer configuration (#3277).

💡 Enhancements 💡

• (Contrib) resourcedetectionprocessor: use opentelemetry-go library for host.id detection in the system detector (#18533)
• (Contrib) k8sattributesprocessor: Store only necessary ReplicaSet and Pod data (#23226)
• (Contrib) k8sclusterreceiver: Do not store unused data in the k8s API cache to reduce RAM usage (#23433)
• (Contrib) pkg/ottl: Add new IsString and IsMap functions to facilitate type checking. (#22750)
  Especially useful for checking log body type before parsing.
• (Contrib) pkg/ottl: Adds StandardFuncs and StandardConverters to facilitate function map generation. (#23190)
  This change means that new functions added to ottlfuncs get automatically added to Cotnrib components that use OTTL
• (Contrib) pkg/ottl: Change replacement functions to accept a path expression as a replacement (#22787)
  The following replacement functions now accept a path expression as a replacement:
  • replace_match
  • replace_pattern
  • replace_all_matches
  • replace_all_patterns
• (Contrib) sapmexporter: sapm exporter now supports compression config option to specify either gzip or zstd compression to use. (#23257)
• (Contrib) sapmreceiver: sapm receiver now accepts requests in compressed with zstd. (#23257)
• (Contrib) exporter/signalfx: Do not drop container.cpu.time metric in the default translations so it can be enabled in the include_metrics config. (#23403)
• (Contrib) sqlqueryreceiver: Add support for logs (#20284)
• (Contrib) k8sclusterreceiver: Switch k8s.deployment metrics to use pdata. (#23416)
• (Contrib) k8sclusterreceiver: Switch k8s.hpa metrics to use pdata. (#18250)
• (Contrib) k8sclusterreceiver: Switch k8s.namespace metrics to use pdata. (#23437)
• (Contrib) k8sclusterreceiver: Switch k8s.node metrics to use pdata. (#23438)
• (Contrib) k8sclusterreceiver: Switch k8s.rq metrics to use pdata. (#23419)
• (Contrib) k8sclusterreceiver: Switch k8s.ss metrics to use pdata. (#23420)
• (Contrib) carbonreceiver: Remove use of opencensus model in carbonreceiver (#20759)
• (Core) service: Added dry run flag to validate config file without running collector. (#4671)
• (Core) configtls: Allow TLS Settings to be provided in memory in addition to filepath. (#7313)
• (Core) connector: Updates the way connector nodes are built to always pass a fanoutconsumer to their factory functions. (#7672, #7673)
• (Core) otlp: update otlp protos to v0.20.0 (#7839)
• (Core) config: Split config into more granular modules (#7895)
• (Core) connector: Split connector into its own module (#7895)
• (Core) extension: split extension and extension/auth into its own module (#7306, #7054)
• (Core) processor: Split the processor into its own go module (#7307)
• (Core) confighttp: Avoid re-creating the compressors for every request. (#7859)
• (Core) otlpexporter: Treat partial success responses as errors (#6686)
• (Core) service/pipelines: Add pipelines.Config to remove duplicate of the pipelines configuration (#7854)

🧰 Bug fixes 🧰

• (Contrib) otel-collector: Fix cri-o log format time layout (#23027)
• (Contrib) receiver/hostmetricsreceiver: Fix not sending process.cpu.utilization when process.cpu.time is disabled. (#23450)
• (Contrib) receiver/kafkametricsreceiver: Updates certain metrics in kafkametricsreceiver to function as non-monotonic sums. (#4327)
  Update the metric type in KafkaMetricsReceiver from "gauge" to "nonmonotonic sum".
• (Contrib) receiver/hostmetrics: Fix issue where receiver fails to read parent-process information for some processes on Windows (#14679)
• (Contrib) k8sclusterreceiver: Fix empty k8s.namespace.name attribute in k8s.namespace.phase metric (#23452)
• (Contrib) splunkhecexporter: Apply multi-metric merge at the level of the whole batch rather than within events emitted for one metric. (#23365)
