Subject Re: Can back pressure data be gathered by Flink metric system?
Date Tue, 16 Apr 2019 01:32:24 GMT
Hi Zhijiang,
	Because I want to know the current and the trend of backpressure status in Flink Job. Like
other index such as latency, I can monitor it, and show it in graph by getting data from metric.
Now using the metric to get the backpressure data is the simplest way I can think.

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.
