🧰 Bug fixes 🧰

• pkg/otlp/metric: Fixes a bug where empty histograms were not being sent to the backend in the distributions mode. (#252)
  • Empty histograms are now mapped as if they had a single (min, max) bucket.

💡 Enhancements 💡

• pkg/otlp/metrics: Add kafka metrics mapping. This allows users of the JMX Receiver/JMX Metrics Gatherer and kafka metrics receiver to have access to the OOTB kafka Dashboard. (#239)

🛑 Breaking changes 🛑

• all: Remove go 1.19 support, bump minimum to go 1.20 and add testing for 1.21 (#159)

🧰 Bug fixes 🧰

• pkg/otlp/metrics: Empty OTLP Exponential Histograms are now dropped instead of causing a crash (#158)

💡 Enhancements 💡

• pkg/inframetadata: Host metadata is now reported the first time new information becomes available for a host. (#150)

🧰 Bug fixes 🧰

• pkg/otlp/metrics: Fix the incorrect for-loop which mutates the same slice while iterating over it, leading to unexpected metric names. Also avoid mutating the input pmetric.Metrics. (#141)
• pkg/otlp/metrics: The minimum and maximum estimation for OTLP Histogram to Datadog distribution mapping now ensures the average is within [min, max]. (#149) This estimation is only used when the minimum and maximum are not available in the OTLP payload or this is a cumulative payload.

🧰 Bug fixes 🧰

• pkg/otlp: Populate OTLP resource attributes in Datadog logs (#138)
• pkg/otlp/metrics: Changes mapping for jvm.loaded_classes from process.runtime.jvm.classes.loaded to process.runtime.jvm.classes.current_loaded (#143)

🛑 Breaking changes 🛑

• pkg/otlp: use new location for updated protobuf definitions in the datadog-agent repo, trace protobuf definitions specifically. (#103) new definitions include mutext to avoid copies, and so implementations should rely on passing arguments by reference and not value.

🚩 Deprecations 🚩

• pkg/otlp/metrics: Deprecate and remove usage of WithPreviewHostnameFromAttributes (#48)

💡 Enhancements 💡

🚩 Deprecations 🚩

• pkg/otlp/metrics: Deprecate metrics.WithCountSumMetrics translator option. (#23)
  • metrics.WithCountSumMetrics will now send min and max metrics when available.
  • Use metrics.WithHistogramAggregations instead.
