  • 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. 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. To get search results, you must have 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.
