     about: Grafana Tempo is an open source, easy-to-use and high-scale distributed tracing backend. Tempo is cost-efficient, requiring only object storage to operate, and is deeply integrated with Grafana, Prometheus, and Loki.
     integration: APL installs and configures Tempo based on best-practices defaults. By default storage is configured to use the tempo bucket of the local Minio instance. For each team a Grafana agent is installed and configured to enable writes to the Tempo cluster.
