---------------------------------

             Summary: Export SlotManager status at debug mode.
                 Key: FLINK-13480
                 URL: https://issues.apache.org/jira/browse/FLINK-13480
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.9.0, 1.10
            Reporter: Guowei Ma


It is very difficult to resolve some resource allocation issues, for example, FLINK-10819 .

One reason is that the status of slotmanager is very difficult to know.  I think we could save a lot of time when troubleshooting problems if the status of slotmanager can export to log 

So I propose to export the status of slotmanager when debug is open.
