[jira] [Commented] (FLINK-13384) The backpressure monitoring tab in WebUI does not show correct results

    [ https://issues.apache.org/jira/browse/FLINK-13384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16890965#comment-16890965 ] 

Dawid Wysakowicz commented on FLINK-13384:
------------------------------------------

I'm still investigating the issue. It's not a problem of the WebUI, but of the backpressure tracker. 

The backpressure metrics are displayed correctly for a map operator(not a source) if I increase the BackPressureStatsTrackerImpl#MAX_STACK_TRACE_DEPTH to 10.
