             Summary: Expose another offsets metrics by using new metric API to specify user defined variables
                 Key: FLINK-8324
                 URL: https://issues.apache.org/jira/browse/FLINK-8324
             Project: Flink
          Issue Type: Improvement
          Components: Kafka Connector
    Affects Versions: 1.5.0
            Reporter: Wei-Che Wei
            Assignee: Wei-Che Wei


The {{current-offsets}} and {{committed-offsets}} metrics are now attached with topic name and partition id in the metric identity.
It is not convenient to use these metrics in Prometheus, because user usually uses the same metric group name to group by those metrics which have the same meaning and uses tags to get the individual metric.
For example, I will prefer to access {{current-offsets}} metric group and use {{partition-x}} tag to get the offset of partition x, instead of getting metric directly from {{current-offsets-partition-x}} metric.
