Audit Log Notes

• Fixed an issue related to the audit_log_prune_seconds system variable. You can now set audit_log_prune_seconds. Checks have been added to ensure audit_log_prune_seconds does not exceed a certain threshold based on other system variable values, including log_offload.log_analytics_schedule and audit_log_rotate_on_time. (Bug #38941456)

• Updated the audit_log_rotate_on_size system variable to require the AUDIT_ADMIN privilege for modification. (Bug #38620615)

Performance Schema Notes

• The following logs are now instrumented for Telemetry Logging:

  • Slow Query Log

  • General Log

  See The setup_loggers Table. (WL #17167)
