DQL to get data based on called service

[tarun_kumar_aga]

Hi

we are noticing high latency in service B, when request called by from service A. We want to plot timeseries graph for serviceB when the request comes from serviceA & show how many requests taking more than 300ms to 3 sec.

Something like this if we can show using DQL will be helpful.
