Description

While using the GraphiteReporter and a simple job with a window function, I noticed that Flink generates metric names which are too long for Graphite to handle.

githubCommits
                .global()
                .windowAll(TumblingEventTimeWindows.of(Time.days(1)))
                .apply(new MyWindowFunction())

The generated metric name was {{/opt/graphite/storage/whisper/172-20-3-229/taskmanager/flink-taskmanager-1-1/Commit-rate-per-day-program/TriggerWindow(TumblingEventTimeWindows(86400000),-ListStateDescriptor

{name=window-contents,-defaultValue=null,-serializer=org-apache-flink-api-common-typeutils-base-ListSerializer@da6e90ca}

,EventTimeTrigger(),-AllWindowedStream-runJob(CommitRateProgram-java:96))->-Sink:-Unnamed/0/numRecordsInPerSecond/m1_rate.wsp}}

The error only shows in the logs of Graphite.
