Cassandra clusters (restbase, sessionstore, aqs, maps) use net.logstash.logback.appender.LogstashSocketAppender for their remote logging, the non-kafka logstash inputs are deprecated and will be turned down EOQ4.
This task is to track onboarding of Cassandra logging to logging pipeline, namely either /dev/log or (more likely, for java) udp syslog on localhost.
