Issue Type: Improvement

Reporter: 赵富午
Attachments: image-2022-01-29-11-55-20-400.png
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.
