赵富午 created FLINK-25875: --------------------------- Summary: "StatsDReporter. FilterCharacters" for special processing of the characters are comprehensive enough Key: FLINK-25875 URL: https://issues.apache.org/jira/browse/FLINK-25875 Project: Flink Issue Type: Improvement Components: Runtime / Metrics Affects Versions: 1.14.3 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. !image-2022-01-29-11-55-38-064.png! [https://nightlies.apache.org/flink/flink-docs-master/docs/ops/metrics/#garbagecollection] JVM "Garbagecollection" grouping, indicators have space characters, indicators cannot be used because indicators cannot be correctly parsed and stored in the database. -- This message was sent by Atlassian Jira (v8.20.1#820001)
