Hello,
I'm using jmx metric node org_apache_cassandra_net_failuredetector_downendpointcount to monitor number of Cassandra nodes down. For any reason (aws schedule retirement) we decommission Cassandra node this metric shows the node down for 72 hours until the gossip clearead. We want keep track of even one node is down as well. Can you please let us know if some one already implemented it
