Subject Can back pressure data be gathered by Flink metric system?
Date Mon, 15 Apr 2019 02:18:55 GMT
Hi Experts,
	From the page Flink metric system(https://ci.apache.org/projects/flink/flink-docs-release-1.8/monitoring/metrics.html#system-metrics
<https://ci.apache.org/projects/flink/flink-docs-release-1.8/monitoring/metrics.html#system-metrics>),
I do not find the info about the back pressure. I want to get the backpressure data and plot
it, but I do not know how to get it via metric. 
	Can anybody help me about it? Thanks a lot.

Best
Henry
