Report dropped stats aggregates in health metrics by amarziali · Pull Request #11231 · DataDog/dd-trace-java

amarziali · 2026-04-29T12:24:56Z

What Does This Do

ConflatingMetricsAggregatorbounds its aggregate cache tomaxAggregates` entries via an LRU eviction policy. When the limit is exceeded, the least-recently-used aggregate is silently discarded — its accumulated hit counts and durations are lost and never reported to the agent.

This PR wires the existing CommonKeyCleaner eviction callback into HealthMetrics, emitting a new StatsD counter stats.dropped_aggregates (tagged reason:lru_eviction) each time an aggregate is evicted.
