Local Storage

In this example all data is stored locally in the tempo-data folder. Local storage is fine for experimenting with Tempo or when using the single binary, but does not work in a distributed/microservices scenario. The container runs as non-root, and so the local directory needs to have the appropriate permissions set in order to start correctly.

  1. First create the storage directory with the correct permissions and start up the local stack.
mkdir tempo-data/
sudo chown 10001:10001 tempo-data/
docker compose up -d

At this point, the following containers should be spun up -

docker compose ps
       Name                     Command               State                                   Ports

  1. If you're interested you can see the wal/blocks as they are being created.
ls tempo-data/

  1. Navigate to Grafana select the Tempo data source and use the "Search" tab to find traces. Also notice that you can query Tempo metrics from the Prometheus data source setup in Grafana.

  2. Tail logs of a container (eg: tempo)

docker logs local_tempo_1 -f
  1. To stop the setup use -
docker compose down -v

search streaming over http

  • need to set traceQLStreaming feature flag in Grafana
  • need to enable stream_over_http_enabled in tempo by setting stream_over_http_enabled: true in the config file.

you can use Grafana or tempo-cli to make a query.

tempo-cli: $ tempo-cli query api search "0.0.0.0:3200" --use-grpc "{}" "2023-12-05T08:11:18Z" "2023-12-05T08:12:18Z" --org-id="test"
