Michael Semb Wever commented on CASSANDRA-9263:
-----------------------------------------------

There's been no requests or comments for this over the past 8 years, so closing this out as 'won't do'. Feel free to disagree and re-open if you have the need for it.

At the system level this can also be done using bpftrace's syncsnoop.bt (and auditctl/auditd on earlier systems).
