USAGE
The wsrep_certificate_expiration_hours_warning system variable can be set in a configuration file:
[mariadb]
...
# warn 3 days before certificate expiration

The global value of the wsrep_certificate_expiration_hours_warning system variable can also be set dynamically at runtime by executing SET GLOBAL:
SET GLOBAL wsrep_certificate_expiration_hours_warning=72;
When the wsrep_certificate_expiration_hours_warning system variable is set dynamically at runtime, its value will be reset the next time the server restarts. To make the value persist on restart, set it in a configuration file too.
