What
When Claude Code exports metrics using OTLP (OpenTelemetry Protocol, a standard format for sending metrics to monitoring systems), datapoints that share the same set of attributes are now grouped together and their numeric values summed into a single row, using the most recent timestamp among them. Previously, each raw datapoint was emitted as its own separate row.
Why
This reduces the number of redundant rows sent to monitoring systems and gives a cleaner, aggregated view of metrics that share the same attributes.
