Hi All,

I want to do a stress testing of my Flink app implementation: event generation with ParallelSourceFunction then measuring the latency ,throughput, CPU & memry leak ...

But when testing, I noticed that :

• the maximum of CPU usage is 30-33%
• latency is always NaNd NaNh in the dashboard ( even I have set this configuration executionConfig.setLatencyTrackingInterval(1); )

Can some one help me find the best solution to smoke testing Flink ?

Note: I'm using Flink 1.3 and the Flink Web UI to visualize the metrics.
Also my PC have a 12Go RAM and 8 Core CPU.

Regards,

Sadok
