Re: How can I prove ....

Hi Stephan,This is from the dashboard. Total Parallelism is set = 1024.259 
tasks per TM. all say Running, but I get *.out log in beam4 server only (bottom 
of the servers list).Does this mean that all nodes are engaged in processing 
the data?Why are these encircled columns having 0's for their data exchange 
report?Thanks+regards,Amir-

You do not need to create any JSON.
Just click on "Running Jobs" in the UI, and then on the job. The parallelism is 
shown as a number in the boxes of the graph.

I guess Stephan is referring to the parallelism of single operators as 
displayed in the operator graph, see e.g. https://ci.apache.org/ 
projects/flink/flink-docs- release-0.10/page/img/ webclient_plan_view.png .

Are you sure you have the parallelism set to 448? You can see the
parallelism of operators in the web UI.

Hi Again, following is from the dashboard while wverything is supposedlt 
running.No real-time change in send/received/#of records...but one node is 
definitely producing a *.out file...And all TMs are reporting in their *.log 
files. And the process will eventually end , but very slow.Thanks again 
Aljoscha.

Hi,depending on the data source you might not be able to stress CPU/MEM because 
the source might be to slow. As long as you see the numbers increasing in the 
Flink Dashboard for all operators you should be good.
