[jira] [Commented] (FLINK-4812) Export currentLowWatermark metric also for sources

    [ https://issues.apache.org/jira/browse/FLINK-4812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15568299#comment-15568299 ] 

Chesnay Schepler commented on FLINK-4812:
-----------------------------------------

The key issue here is to register the watermark for the task and not the operator. I think this is also why i didn't add it back then.

> As reported by a user, Flink does currently not export the current low watermark for sources (http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/currentLowWatermark-metric-not-reported-for-all-tasks-td13770.html).
> This JIRA is for adding such a metric for the sources as well.
