TheHTTP module provides/trace endpoint which allows to trace variousaspects of the request execution. The basic mode allows you to resolve a queryand trace verbose logs for it (and messages received):

$ curl https://localhost:8453/trace/e.root-servers.net[8138][iter]'e.root-servers.net.'type'A' created outbound query, parent id0[8138][ rc]=> rank:020, lowest020, e.root-servers.net.
