I know flink collects latency metrics out of box, but I want to know how can I get the latency data of my job.
Do I have to use custom reporter(e.g. graphite) to view the latency?
I saw there is latency metrics in flink dashboard, but no data when I added the latency of a sink operator. If this is not the latency data, what is it?
Thank you.
I am using Flink V1.2.1 by the way.
