Subject [jira] [Created] (CASSANDRA-16859) allow blocking IPs from updating metrics about traffic
Date Mon, 16 Aug 2021 23:16:00 GMT
David Capwell created CASSANDRA-16859:
-----------------------------------------

             Summary: allow blocking IPs from updating metrics about traffic
                 Key: CASSANDRA-16859
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16859
             Project: Cassandra
          Issue Type: Improvement
          Components: Observability/Metrics
            Reporter: David Capwell
            Assignee: David Capwell


It is common that network scans happen for some companies, and when these scans happen they
will send packets to the Cassandra ports which do not match our protocol; when this happens
we fail and increment metrics to show this.  To avoid these scans polluting our metrics, we
should allow users to block their own IP subnets from updating these metrics.
