# Tempo data source
Grafana ships with built-in support for Tempo a high volume, minimal dependency trace storage, OSS tracing solution from Grafana Labs. Add it as a data source, and you are ready to query your traces in [Explore]({{< relref "../explore/index.md" >}}).
## Adding the data source
To access Tempo settings, click the **Configuration** (gear) icon, then click **Data Sources** > **Tempo**.
| Name | Description |
| --------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| _Name_ | The data source name using which you will refer to the data source in panels, queries, and Explore. |
| _Default_ | The default data source will be pre-selected for new panels. |
| _URL_ | The URL of the Tempo instance, e.g., `http://localhost:16686` |
| _Basic Auth_ | Enable basic authentication to the Tempo data source. |
| _User_ | User name for basic authentication. |
| _Password_ | Password for basic authentication. |
## Query traces
You can query and display traces from Tempo via [Explore]({{< relref "../explore/index.md" >}}).
To query a particular trace, insert its trace ID into the query text input.

## Linking Trace ID from logs
You can link to Tempo trace from logs in Loki or Elastic by configuring an internal link. See the [Derived fields]({{< relref "loki.md#derived-fields" >}}) section in the [Loki data source]({{< relref "loki.md" >}}) or [Data links]({{< relref "elasticsearch.md#data-links" >}}) section in the [Elastic data source]({{< relref "elasticsearch.md" >}}) for configuration instructions.
