ASF GitHub Bot commented on FLINK-1502: --------------------------------------- Github user zentol commented on the pull request: https://github.com/apache/flink/pull/1947#issuecomment-217368732 @rmetzger you are correct that you're job failed since the previous one wasn't cleaned up yet. Should you try to run 2 identical jobs in parallel it will fail, since 2 jobs would use the same metrics due to name clashes. Note that in this version this also occurs when 2 operators have the same name. I have some additional functionality coming up that would allow you to circumvent this issue. @ankitcha The problem with multiple reporters is our configuration, it only supports single-line key-value pairs, and you need to know the exact key to access it. In order to configure multiple reporters you would either need a nested structure (which is not supportet), or index the configuration keys (metrics.reporter.1.class) and add a new parameter containing the indices to use (e.g. metrics.reporter: 0, 1), which isn't particularly user-friendly. The metric system itself could deal with multiple reporters with minor modifications; it's all about the configuration. > Expose metrics to graphite, ganglia and JMX. > -------------------------------------------- > > Key: FLINK-1502 > URL: https://issues.apache.org/jira/browse/FLINK-1502 > Project: Flink > Issue Type: Sub-task > Components: JobManager, TaskManager > Affects Versions: 0.9 > Reporter: Robert Metzger > Assignee: Chesnay Schepler > Priority: Minor > Fix For: pre-apache > > > The metrics library allows to expose collected metrics easily to other > systems such as graphite, ganglia or Java's JVM (VisualVM). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
