      Description

      Currently, its quite hard to figure out issues with the watermarks.

      I think we can improve the situation by reporting the following information through the metrics system:

      • Report the current low watermark for each operator (this way, you can see if one operator is preventing the watermarks to rise)
      • Report the number of events arrived after the low watermark (users can see how accurate the watermarks are)
