# Grafana Tempo configuration for xrpld telemetry stack.
#
# Runs in single-binary mode for local development.
# Receives traces via OTLP/gRPC from the OTel Collector and stores
# them locally. Queryable via Grafana Explore using the Tempo datasource.
#
# Search filters are configured on the Grafana datasource side
# (grafana/provisioning/datasources/tempo.yaml). Tempo auto-indexes
# all span attributes for search in single-binary mode.
#
# For production, replace local storage with S3/GCS backend and adjust
# retention via the compactor settings. See:
# https://grafana.com/docs/tempo/latest/configuration/
