> I'm looking for a way to extend the builtin throughput and latency metrics for operators with my own metric variables.
> My specific use case:
> I have a job that defines a list of independent source -> sink streams. I would like to add my own metric variables to each of these independent streams. For example, something like this:
> {code:scala}
> class MyFilter extends RichFilterFunction {
>   override def open(parameters: Configuration): Unit = {
>     val mg = getRuntimeContext.getMetricGroup // Includes "streamName" -> "A|B"
>     // Init some user defined metrics here...
>   }
> }
> // Stream A
> // Native operator metrics and user defined metrics in rich operators include "streamName" -> "A"
> streamA = env.withMetricGroup((mg) => mg.addGroup("streamName", "A").addSource(...).filter(new MyFilter).addSink(...)
> // Stream B
> // Native operator metrics and user defined metrics in rich operators include "streamName" -> "B"
> streamB = env.withMetricGroup((mg) => mg.addGroup("streamName", "B").addSource(...).filter(new MyFilter).addSink(...)
> {code}
>  
> Is this possible? Would a new hook into StreamTransformation have to be added?
