Subject [jira] [Created] (CASSANDRA-14795) Expose information about stored hints via JMX
Date Thu, 27 Sep 2018 13:13:00 GMT
Aleksandr Sorokoumov created CASSANDRA-14795:
------------------------------------------------

             Summary: Expose information about stored hints via JMX
                 Key: CASSANDRA-14795
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14795
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Aleksandr Sorokoumov
            Assignee: Aleksandr Sorokoumov


Currently there is no way to determine what kind of hints a node has, apart from looking at
the filenames (thus host-ids) on disk. Having a way to access this information would help
with debugging hint creation/replay scenarios.
In addition to the JMX method, there is a new nodetool command:


{noformat}$ bin/nodetool -h 127.0.0.1 -p 7100 listendpointspendinghints
Host ID Address Rack DC Status Total files Newest Oldest
