Can we keep the indentation as before? I think Angular is a little picky
with the config here and if we uncomment this line with the new indentation it
will not parse the jobServer value. I'm not sure about this. If you think it's
not a problem, it's OK to leave it as is.

> Issue Type: Improvement
> Components: Streaming, Webfrontend
> Reporter: Robert Metzger

> 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)
