[jira] [Resolved] (CASSANDRA-8602) ArithmethicException: Divide by
zero in agent (cassandra)
[ https://issues.apache.org/jira/browse/CASSANDRA-8602?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nick Bailey resolved CASSANDRA-8602.
------------------------------------
Resolution: Invalid
So this is just the issue tracker for Apache Cassandra doesn't include tracking issues for OpsCenter, so I'm going to close this here.
The best way to report issues like this for OpsCenter is via the feedback form in the OpsCenter interface.
For this particular bug, we are tracking this internally and it should be fixed in the next major release of OpsCenter. In the meantime, the bug should be mostly harmless, except for the alarming logging. Thanks for the report though.
