Jamie Grier commented on FLINK-1502:
------------------------------------
To be clear what I meant here is to have the indexes assigned to the
TaskManagers scoped to the *entire* cluster. Not a particular host like what
you're describing here. So, for example, if you spun up a Flink cluster with
10 TaskManagers running on 10 different hosts the TaskManager's would be given
a unique INDEX on the cluster. Literally, TaskManager[1-10]. Use this to
scope the metrics, e.g.:
cluster.MyCluster.taskmanager.1.gc_time
cluster.MyCluster.taskmanager.2.gc_time
...
...
cluster.MyCluster.taskmanager.10.gc_time
It doesn't matter which hosts they are on. These are 10 unique JVMS on some
set of hosts.
> Expose metrics to graphite, ganglia and JMX.
