completeness: 0.84
known_gaps:
  - Metric behavior depends on SDK language, exporter, collector pipeline, aggregation temporality, resource attributes, view configuration, backend translation, sampling, exemplar filters, and cardinality limits.
  - Exemplars can improve trace-to-metric debugging, but they can also retain filtered attributes unless SDK and collector configuration handle privacy and sampling deliberately.

## TL;DR

OpenTelemetry metric evidence is only useful when agents preserve temporality, resource identity, labels, and exemplar behavior instead of copying a dashboard value without its data model.

## Core Explanation

Metrics can explain latency, error rates, saturation, and rollout regressions, but agent conclusions need the exact metric stream. Useful evidence includes metric name, unit, instrument type, resource attributes, aggregation, temporality, start and end timestamps, labels, exporter, collector transforms, and backend query.

Temporality matters because cumulative and delta streams support different interpretations of rates, restarts, and gaps. Exemplars matter because they can connect a metric outlier to a trace or span. Agents should also check view and collector configuration because attributes removed from the main time series may still appear in exemplar data if exemplar sampling is enabled.
