Confuse to check ping or mysql

Hi

Ping is just to see whether the machine is alive. It might not even accept TCP connections. It's a very basic check.

The MySQL check actually connects to the MySQL or MariaDB server.

Regards,
Arjen.

Hi Arjen Lentz,

Thank you for your reply. How about the trap_period and timeout?
