- **Data source -** Target data source.
- **Tags -** The tags that will be used in the Loki query. Default is `'cluster', 'hostname', 'namespace', 'pod'`.
- **Map tag names -** When enabled, allows configuring how Jaeger tag names map to Loki label names. For example, map `service.name` to `service`.
- **Span start time shift -** Shift in the start time for the Loki query based on the span start time. In order to extend to the past, you need to use a negative value. Use time interval units like 5s, 1m, 3h. The default is 0.
- **Span end time shift -** Shift in the end time for the Loki query based on the span end time. Time units can be used here, for example, 5s, 1m, 3h. The default is 0.
- **Filter by Trace ID -** Toggle to append the trace ID to the Loki query.
- **Filter by Span ID -** Toggle to append the span ID to the Loki query.

## Linking Trace ID from logs
You can link to Zipkin trace from logs in Loki by configuring a derived field with internal link. See [Loki documentation]({{< relref "loki#derived-fields" >}}) for details.
