v0.111.0

The OpenTelemetry Collector Contrib contains everything in the opentelemetry-collector release, be sure to check the release notes there as well.

🆕 The binary release adds a new OTLP-only distro. Feel free to leave us feedback on this new distro on the opentelemetry-collector-releases issue tracker.

⚠️ The core release removes the logging exporter. See open-telemetry/opentelemetry-collector#11337 for instructions on how to migrate to the debug exporter.

🛑 Breaking changes 🛑

• instanaexporter: Remove deprecated instanaexporter (#35367)
  Use the otlp exporter instead as explained in IBM's documentation.
• elasticsearchexporter: Drop cumulative temporality histogram and exponential histogram (#35442)
  Cumulative temporality histogram and exponential histogram are not supported by Elasticsearch. Use cumulativetodeltaprocessor to convert cumulative temporality to delta temporality.
• elasticsearchexporter: Implement receiver-based routing under *_dynamic_index config (#34246)
• config: Move component.UseLocalHostAsDefaultHost feature gate to stable. (#35569)
• metricsgenerationprocessor: Generate metrics even when the second metric's value is 0 (#35533)
• signalfxexporter: Do not exclude the metric container.memory.working_set (#35475)
• sqlqueryreceiver: Fail if value for log column in result set is missing, collect errors (#35068)
• windowseventlogreceiver: The 'raw' flag no longer suppresses rendering info. (#34720)
  Previously, this flag controlled two behaviors simultaneously:
  1. Whether or not the body of the log record was an XML string or structured object.
  2. Whether or not rendering info was resolved.
     A separate 'suppress_rendering_info' option now controls rendering info resolution.
     This is considered a breaking change because users setting only the 'raw' flag without also setting the
     new 'suppress_rendering_info' flag may see a performance decrease along with more detailed events.

🚩 Deprecations 🚩

  When this flag is enabled, the receiver will not attempt to resolve rendering info. This can improve performance
  but comes at a cost of losing some details in the event log.

• windowseventlogreceiver: Move artificial "remote_server" field to 'attributes["server.address"]'. (#34720)

  To retain the previous behavior, set retry.retry_on_status to [429, 500, 502, 503, 504].

• gitproviderreceiver: Update metric names and attributes to match the newest Semantic Conventions for VCS. (#34278)
  Attribute Changes:

  • branch.name is now ref.name
  • Added a ref.type attribute
  • pull_request.state is now change.state
  • git.vendor.name is now vcs.vendor.name
    Metric Changes:
  • git.repository.count is now vcs.repository.count
  • git.repository.contributor.count is now vcs.repository.contributor.count
  • git.repository.branch.count is now vcs.repository.ref.count
  • git.repository.branch.time is now `vcs.repository.ref.time
  • git.repository.branch.commit.aheadby.count is now vcs.repository.ref.revisions_ahead
  • git.repository.branch.commit.behindby.count is now `vcs.repository.ref.revisions_behind
  • git.repository.branch.line.addition.count is now vcs.repository.ref.lines_added
  • git.repository.branch.line.deletion.count is now vcs.repository.ref.lines_deleted

  • git.repository.pull_request.count is now vcs.change.count

• transformprocessor: Promote processor.transform.ConvertBetweenSumAndGaugeMetricContext feature flag from alpha to beta (#34567)

• exporter/datadog: The logs::dump_payloads config option is invalid when the Datadog Agent logs pipeline is enabled (now enabled by default). (#34420)
  An error will be raised if logs::dump_payloads is set while the Datadog Agent logs pipeline is enabled. To avoid this error, remove the logs::dump_payloads config option or temporarily disable the exporter.datadogexporter.UseLogsAgentExporter feature gate.

• vcenterreceiver: Several host performance metrics now return 1 data point per time series instead of 5. (#34708)
  The 5 data points previously sent represented consecutive 20s sampling periods. Depending on the collection interval
  these could easily overlap. Sending just the latest of these data points is more in line with other performance metrics.

  This change also fixes an issue with the googlecloud exporter seeing these datapoints as duplicates.

  Following is the list of affected metrics which will now only report a single datapoint per set of unique attribute values.

  • vcenter.host.cpu.reserved
  • vcenter.host.disk.latency.avg
  • vcenter.host.disk.latency.max
  • vcenter.host.disk.throughput
  • vcenter.host.network.packet.drop.rate
  • vcenter.host.network.packet.error.rate
  • vcenter.host.network.packet.rate
  • vcenter.host.network.throughput
  • vcenter.host.network.usage

🚀 New components 🚀

• exporter/doris: Add a new component for exporting logs, traces and metrics to Doris (#33479)

💡 Enhancements 💡

• geoipprocessor: Add a context configuration option to specify the IP address attribute telemetry location. (#34036)
• awss3receiver: Enhance the logging of the AWS S3 Receiver in normal operation to make it easier for user to debug what is happening. (#30750)
• datadogreceiver: Implement '/info' endpoint (#34772)
• datadogreceiver: Add sampling.priority attribute for Probabilistic Sampling Processor (#34267)
• datadogreceiver: Implement '/stats' endpoint (#34790)
• datadogconnector: Add a config traces::bucket_interval (#34554)
  traces::bucket_interval specifies the time interval size of aggregation buckets that aggregate the Datadog trace metrics. It is also the time interval that Datadog trace metrics payloads are flushed to the pipeline. Default is 10s if unset.
• deltatocumulative: Promote to alpha stability (#34747)
  promotes the deltatocumulative processor to alpha stability, as most features are now implemented and ready for wider testing.
• deltatocumulative: explicit-bounds histograms (#30705)
  implements aggregation of explicit-bounds (traditional) histograms.
• elasticsearchexporter: Add OTel mapping mode for metrics (#34248)
• elasticsearchexporter: Add OTel mapping mode for traces (#34588, #34590)
  Add OTel mapping mode support for traces, without span events.
• filelogreceiver: If acquire_fs_lock is true, attempt to acquire a shared lock before reading a file. (#34801)
  Unix only. If a lock cannot be acquired then the file will be ignored until the next poll cycle.
• solacereceiver: Updated the format for generated metrics. Included a receiver_name attribute that identifies the Solace receiver that generated the metrics (#34541)
• geoipprocessor: Move processor's stability to alpha. (#34737)
• prometheusreceiver: Ensure Target Allocator's confighttp is used in the receiver's service discovery (#33370)

• pkg/ottl: Introduce UserAgent converter to parse UserAgent strings (#32434)

🧰 Bug fixes 🧰

• tailsamplingprocessor: Update the policy value in metrics dimension value to be unique across multiple tail sampling components with the same policy name. (#34192)
  This change ensures that the policy value in the metrics exported by the tail sampling processor is unique across multiple tail sampling processors with the same policy name.

• datadogreceiver: add feature discovery (#34718)

• datadogconnector: Put back the otelcol_ prefix for Datadog internal metrics on trace and APM stats exporting (#34807)
  Recovers these metrics from an upstream breaking change. See open-telemetry/opentelemetry-collector#9759 and open-telemetry/opentelemetry-collector#10940.

• connector/exceptionsconnector: Fix dimensions configuration did not take effect for resource attributes (#34603)

• prometheusreceiver: Group scraped metrics into resources created from job and instance label pairs (#34237)
  The receiver will now create a resource for each distinct job/instance label combination.
  In addition to the label/instance pairs detected from the scraped metrics, a resource representing the overall
  scrape configuration will be created. This additional resource will contain the scrape metrics, such as the number of scraped metrics, the scrape duration, etc.

• cmd/opampsupervisor: Fix supervisor support for Windows. (#34570)

• tailsamplingprocessor: Fix the behavior for numeric tag filters with inverse_match set to true. (#34296)

End User Changelog

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.
