+The most important values to set up are the following:

+- Mark the data source as default, so the url from Kiali redirects properly to the Tempo data source. 
+- Update the http url. This is the internal url of the http tempo frontend service. E.g. `http://tempo-tempo-query-frontend.tempo.svc.cluster.local:3200/`

 The _Traces_ tab will show your traces in a bubble chart:
