Subject [jira] [Created] (FLINK-4206) Metric names should alle special characters
Date Wed, 13 Jul 2016 08:52:20 GMT
Chesnay Schepler created FLINK-4206:
---------------------------------------

             Summary: Metric names should alle special characters
                 Key: FLINK-4206
                 URL: https://issues.apache.org/jira/browse/FLINK-4206
             Project: Flink
          Issue Type: Improvement
          Components: Metrics
    Affects Versions: 1.1.0
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.1.0


Currently, the name of the metric is restricted to alphanumeric characters. This restriction
was originally put in place to circumvent issues due to systems not supporting certain characters.

However, this restriction does not make a lot of sense since for group names we don't enforce
such a restriction.

This also affects the integration of the Kafka metrics, so i suggest removing the restriction.

>From now on it will be the responsibility of the reporter to make sure that the metric
identifier is supported by the external system.
