Subject [jira] [Commented] (FLINK-1502) Expose metrics to graphite, ganglia and JMX.
Date Thu, 18 Feb 2016 19:21:18 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15152917#comment-15152917

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.:


It doesn't matter which hosts they are on.  These are 10 unique JVMS on some set of hosts.
