Grafana Tempo — sequence diagrams
One diagram per scenario; each tab is one scenario from the source.
- Traces · ingest
- Traces · search
App SDKs export OTLP spans to Alloy. Tempo's distributor hashes by trace ID so a trace lands whole; metrics-generator derives RED metrics into Mimir as a side effect.
TraceQL search or trace-ID lookup. Query-frontend shards the search; queriers use bloom filters to skip blocks, reading only the Parquet columns the query needs.
