v0.107.0

This release fixes CVE-2024-42368 on the bearerauthtokenextension (#34516)

🛑 Breaking changes 🛑

• clickhouseexporter: Add compress option to ClickHouse exporter, with default value of lz4 (#34365)
  This change adds a new compress option to the config field and enables it by default.
  Prior to this change, compression was not enabled by default.
  The only way to enable compression prior to this change was via the DSN URL.
  With this change, lz4 compression will be enabled by default.
  The list of valid options is provided by the underlying clickhouse-go driver.
  While this change is marked as breaking, there should be no effect to existing deployments by enabling compression.
  Compression should improve network performance on most deployments that have a remote ClickHouse server.

• Update the scope name for telemetry produce by components. The following table summarizes the changes:

• elasticsearchreceiver: Enable more index metrics by default (#34396)
  This enables the following metrics by default:
  elasticsearch.index.documents
elasticsearch.index.operations.merge.current
elasticsearch.index.segments.count
  To preserve previous behavior, update your Elasticsearch receiver configuration to disable these metrics.
• vcenterreceiver: Enables all of the vSAN metrics by default. (#34409)
  The following metrics will be enabled by default now:
  • vcenter.cluster.vsan.throughput
  • vcenter.cluster.vsan.operations
  • vcenter.cluster.vsan.latency.avg
  • vcenter.cluster.vsan.congestions
  • vcenter.host.vsan.throughput
  • vcenter.host.vsan.operations
  • vcenter.host.vsan.latency.avg
  • vcenter.host.vsan.congestions
  • vcenter.host.vsan.cache.hit_rate
  • vcenter.vm.vsan.throughput
  • vcenter.vm.vsan.operations
  • vcenter.vm.vsan.latency.avg

🚩 Deprecations 🚩

• exporter/datadog: Deprecates logs::dump_payloads since it is invalid with the Datadog Agent logs pipeline, which will be enabled by default in the v0.108.0 release. (#34490)

🚀 New components 🚀

• logdedupeprocessor: Add new logdedupeprocessor processor that deduplicates log entries. (#34118)
• coralogixprocessor: creating new component for coralogix features (#33090)
• googlecloudmonitoringreceiver: Adding new component - Google Cloud monitoring receiver to fetch GCP Cloud Metrics and transform to OpenTelemetry compatible format. (#33762)

💡 Enhancements 💡

• awsemfexporter: AWS EMF Exporter to update ApplicationSignals log group name and namespace, and adjust AWS service name prefix logic in spans (#33798)

• azureeventhubreceiver: Added traces support in azureeventhubreceiver (#33583)

• exporter/prometheusremotewrite: Reduce unnecessary memory allocation by removing buffer that was not used by Snappy encoding function. (#34273)

• exporter/prometheusremotewrite: Reduce memory allocations of prometheus remote write exporter "batchtimeseries" when large batch sizes are used (#34269)

• clickhouseexporter: Updated the default logs table to a more optimized schema (#34203)
  Improved partitioning and time range queries.

• bearertokenauthextension: use constant time comparison. This fixes CVE-2024-42368 (#34516)

• processor/k8sattributes: Add support for container.image.repo_digests metadata (#34029)

• datadogconnector: Move feature gate connector.datadogconnector.NativeIngest to beta (#34549)
  When this feature gate is enabled (default), the datadog connector uses the new API to produce APM stats under the hood. | The new API has better throughput when your spans have many attributes (especially container related attributes). Funtional-wise the new API should have no user-facing change compared to the old API. | However if you observe any unexpected behaviors, you can disable this feature gate to revert to the old stats processing APIs.

• elasticsearchexporter: Add opt-in support for the experimental batcher config (#32377)
  By enabling (or explicitly disabling) the batcher, the Elasticsearch exporter's
  existing batching/buffering logic will be disabled, and the batch sender will be used.

• elasticsearchexporter: Add summary support for metrics (#34560)

• hostmetricsreceiver: add reporting interval to entity event (#34240)

• elasticsearchreceiver: Add metric for active index merges (#34387)

• kafkaexporter: add an ability to partition logs based on resource attributes. (#33229)

• logdedupprocessor: Adds a histogram metric to record the number of aggregated log records. (#34579)

• logdedupprocessor: Updates stability level to alpha. (#34575)

• logdedup: Make the name of the log deduplication component consistent (#34571)

• logdedupprocessor: Ensures any pending aggregated logs are processed and sent to the next consumer before shutting down. (#34615)

• logdedupprocessor: Adds a scope aggregator to the logdedup processor enabling the aggregation of logs per scope. (#34606)

• logdedupprocessor: Simplifies the processor shutdown behaviour by removing the unnecessary done channel. (#34478)

• pkg/ottl: Add support for map literals in OTTL (#32388)

• pkg/ottl: Introduce ExtractGrokPatterns converter (#32593)

• pkg/ottl: Add the MD5 function to convert the value into a MD5 hash/digest (#33792)

• pkg/ottl: Introduce sha512 converter to generate SHA-512 hash/digest from given payload. (#34007)

• kafkametricsreceiver: Add option to configure cluster alias name and add new metrics for kafka topic configurations (#34148)

• receiver/splunkhec: Add a regex to enforce metrics naming for Splunk events fields based on metrics documentation. (#34275)

• telemetrygen: Support boolean values in --telemetry-attributes and --otlp-attributes flag (#18928)

• filelogreceiver: Check for unsupported fractional seconds directive when converting strptime time layout to native format (#34390)

• windowseventlogreceiver: Add remote collection support to Stanza operator windows pkg to support remote log collect for the Windows Event Log receiver. (#33100)

🧰 Bug fixes 🧰

• configauth: Fix unmarshaling of authentication in HTTP servers. (#34325)
  This brings in a bug fix from the core collector. See open-telemetry/opentelemetry-collector#10750.

• docker_observer: Change default endpoint for docker_observer on Windows to npipe:////./pipe/docker_engine (#34358)

• pkg/translator/jaeger: Change the translation to jaeger spans to match semantic conventions. (#34368)
  otel.library.name is deprecated and replaced by otel.scope.name
otel.library.version is deprecated and replaced by otel.scope.version

• pkg/stanza: Ensure that errors from Process and Write do not break for loops (#34295)

• cmd/opampsupervisor: Start even if the OpAMP server cannot be contacted, and continually retry connecting. (#33408, #33799)

• cmd/opampsupervisor: Write the generated effective config and agent log files to the user-defined storage directory. (#34341)

• azuremonitorreceiver: Add Azure China as a cloud option. (#34315)

• postgresqlreceiver: Support unix socket based replication by handling null values in the client_addr field (#33107)

• splunkhecexporter: Copy the bytes to be placed in the request body to avoid corruption on reuse (#34357)
  This bug is a manifestation of golang/go#51907.
  Under high load, the pool of buffers used to send requests is reused enough
  that the same buffer is used concurrently to process data and be sent as request body.
  The fix is to copy the payload into a new byte array before sending it.

• syslogexporter: Fix issue where exporter may hang indefinitely while dialing. (#34393)

• clickhouseexporter: Use observed timestamp if timestamp is zero (#34150)
  Some OpenTelemetry libraries do not send timestamp for logs, but they should always send | the observed timestamp. In these cases the ClickHouse exporter just stored a zero timestamp | to the database. This changes the behavior to look into the observed timestamp if the timestamp | is zero.

• webhookeventreceiver: added a timestamp to the logs generated from incoming events. (#33702)
