After upgrading to 1.26 of cassandra_monitor, there still seems to be an issue as I am getting the alarms that "cassandra is not running on this node." In AC, I'm able to expand the Cluster and System nodes, however in cassandra_monitor->robotName->Cassandra->clusterName->nodeName where it lists Binary, Gossip, Incremental Backup, etc. - none of those can be expanded, and selecting them just shows the "space intentionally left blank" text instead of metrics.
