Jamie Grier commented on FLINK-1502:
------------------------------------
Is there no way to refer to a TaskManager by index in order to solve this
problem. It would be nice if we didn't have to send all the metrics through
the JobManager but rather just report them via JMX locally on each host. I
think I understand the problem you are describing but would just having a
logical index for each TaskManager solve this problem. I would like to avoid
having to send the metrics through a central node if possible as I would like
to see the # of total metrics go up dramatically as we instrument the code more
and more.
> Expose metrics to graphite, ganglia and JMX.
