> I based on the 「org.Apache.Flink.Metrics.Statsd.StatsDReporter」 metrics collection, query and display and use 「Graphite」, I found some flink metrics cannot be queried to, after screening, I found the reason, These indicators cannot be parsed because they contain space characters. I further track source code, I found 「StatsDReporter.FilterCharacters」 function for the processing of special characters is not qualified, only to replace ":" character, for other special characters and didn't do a good replacement, such as a space character.

> JVM "Garbagecollection" grouping, indicators have space characters, indicators cannot be used because indicators cannot be correctly parsed and stored in the database.
