Percona audit_log_filter not working

Has anyone had any luck using the audit_log_filter plugin / component from Percona?

I have installed Percona Server for MySQL 8.0 (8.0.41-32) and Percona Server for MySQL 8.4 (8.4.3-3) and followed the instructions to install it.I'm using Debian 12 (bookworm) if that makes any difference.

e.g.

1. run the script audit_log_filter_linux_install.sql to create the two tables and install the plugin / component.

2. set up logging using:

   SELECT audit_log_filter_set_filter('log_all', '{"filter": {"log": true}}');

   SELECT audit_log_filter_set_user('%', 'log_all');

This should enable logging of all events for all users.

I then run a series of queries, that include create schema / create table / insert / update / delete / drop etc.I've tried it with different usersI've tried it on workbench and from the cmdline

And yet the only thing that ever appears in the log is:

<?xml version="1.0" encoding="utf-8"?><AUDIT><AUDIT_RECORD><NAME>Audit</NAME><RECORD_ID>0_2025-03-13T11:47:51</RECORD_ID><TIMESTAMP>2025-03-13T11:47:51</TIMESTAMP><SERVER_ID>1</SERVER_ID></AUDIT_RECORD>

which is generated when the server restarts.

Am I missing something, or does it simply not work?
