How to detect connection errors on MySQL2 pool when MySQL service stops?

[tsp1998]

I'm trying to detect connection errors on a MySQL2 connection pool when the MySQL service stops. I noticed that pool.on('error') doesn't trigger when the MySQL server goes down. Here's what I want to achieve:

Detect when the MySQL service stops or becomes unavailable.
Handle this error gracefully and attempt reconnection.
Optionally, log or alert when the service is unavailable.
