# Tempo

This root renders `grafana-community/tempo` chart `2.2.3` as one Tempo
`2.10.7` StatefulSet in `observability`.

- The image is rewritten to the reviewed amd64 digest.
- Traces use the `tempo` AIStor bucket through `tempo-object-storage`; no root
  credential is referenced.
- Retention is seven days. WAL and local working data use the dedicated 5Gi
  Retain Local PV.
- Only the query/metrics port 3200 and OTLP/gRPC port 4317 are exposed.
- OTLP/HTTP, Jaeger, Zipkin, metrics-generator, and tempo-query are disabled.

Do not delete the PVC or bucket during rollback. Stop the StatefulSet and
preserve its Retain volume while S3/WAL state is investigated.
