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" >}}).

Add data source

To access Tempo settings, click the Configuration (gear) icon, then click Data Sources > Tempo.

Name	Description
`Name`	The 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://tempo`
`Basic Auth`	Enable basic authentication to the Tempo data source.
`User`	User name for basic authentication.
`Password`	Password for basic authentication.

Trace to logs

Note: This feature is available in Grafana 7.4+.

This is a configuration for the [trace to logs feature]({{< relref "../explore/trace-integration" >}}). Select target data source (at this moment limited to Loki data sources) and select which tags will be used in the logs query.

Data source - Target data source.
Tags - The tags that will be used in the Loki query. Default is 'cluster', 'hostname', 'namespace', 'pod'.

Query traces

You can query and display traces from Tempo via [Explore]({{< relref "../explore/_index.md" >}}). You can search for traces if you set up the trace to logs setting in the data source configuration page. To find traces to visualize, use the [Loki query editor]({{< relref "loki.md#loki-query-editor" >}}). To get search results, you must have [derived fields]({{< relref "loki.md#derived-fields" >}}) configured, which point to this data source.

To query a particular trace, select the TraceID query type, and then put the ID into the Trace ID field.

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.
