------------------------------------

             Summary: StatsD does not accept metrics whose name contains ":"
                 Key: FLINK-4171
                 URL: https://issues.apache.org/jira/browse/FLINK-4171
             Project: Flink
          Issue Type: Bug
          Components: Metrics
    Affects Versions: 1.1.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.1.0


The {{StatsDReporter}} mustn't send metrics whose name contains a ":" character to {{StatsD}} because these reports are discarded. The reason is that ":" is used to separate the value from the metric name.

I propose to check the metric names and replace all ":" by a "-" character.
