Hey Stephan, My company (OpsClarity) is building monitoring integration for flink, and being that backpressure is one of the most critical concepts in a streaming system, we need a way to expose backpressure state to a monitoring system (such as ours). I see that the flink-ui has a way to sample the pipeline and mark a stage as high|med|ok wrt backpressure. I'd love to be able to encode that as a metric, perhaps as simple as 2|1|0, so that we can plot backpressure state over time per stage. This would also allow users to set alerts on backpressure state.
How might we get access to this backpressure state information?
