> 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.
