What kind of actions? nodetool/system actions or cql statements?
You could probably achieve identity-based logging with logback Mapped
Diagnostic Context (MDC - logback.qos.ch/manual/mdc.html), but you'd need
to patch your own Cassandra jars in many locations to provide that
information to the logging context, so not exactly a trivial thing to do.
We tried using that to print ks/cf names on log messages but it became a
bit messy due to the SEDA architecture as you need to patch executors to
inherit identifiers from parent threads and cleanup afterwards. See
CASSANDRA-7276 for more background.
