Tempo query editor
The Tempo data source’s query editor helps you query and display traces from Tempo in Explore.
This topic explains configuration and queries specific to the Tempo data source. For general documentation on querying data sources in Grafana, see Query and transform data.
Query by search
Use this to search for traces by service name, span name, duration range, or process-level attributes that are included in your application’s instrumentation, such as HTTP status code and customer ID.
To configure Tempo and the Tempo data source for search, refer to Configure the data source.
To search for traces:
- Select Search from the Query type selector.
- Fill out the search form:
| Name | Description |
|---|---|
| Service Name | Returns a list of services. |
| Span Name | Returns a list of span names. |
| Tags | Sets tags with values in the logfmt format, such as error=true db.statement="select * from User". |
| Min Duration | Filters all traces with a duration higher than the set value. Possible values are 1.2s, 100ms, 500us. |
| Max Duration | Filters all traces with a duration lower than the set value. Possible values are 1.2s, 100ms, 500us. |
| Limit | Limits the number of traces returned. |
Search recent traces
You can search recent traces held in Tempo’s ingesters. By default, ingesters store the last 15 minutes of tracing data.
To configure your Tempo data source to use this feature, refer to the Tempo documentation.
Search the backend datastore
Tempo includes the ability to search the entire backend datastore.
To configure your Tempo data source to use this feature, refer to the Tempo documentation.
Query by TraceID
To query a particular trace:
- Select the TraceID query type.
- Enter the trace’s ID into the Trace ID field.
Query by TraceQL
To learn more about how to query by TraceQL, refer to the TraceQL documentation.
Query Loki for traces
To find traces to visualize, you can use the Loki query editor. For results, you must configure derived fields in the Loki data source that point to this data source.
