# Grafana Loki data source provisioning for rippled log-trace correlation.
#
# Phase 8: Log-Trace Correlation and Centralized Log Ingestion
#
# Loki ingests rippled logs via OTel Collector's filelog receiver.
# The derivedFields config links trace_id values in log lines back to
# Tempo traces, enabling one-click log-to-trace navigation in Grafana.
#
# See: OpenTelemetryPlan/Phase8_taskList.md (Tasks 8.2, 8.4)
