Key process Monitoring

MYSQLD: Process exited, alarm. Monitor mysqld (CPU (>=100%) | | mem (>=80%)) to start alerting while collecting and analyzing MySQL status information; number of connections (>=max_connections * 0.8) Start alert; number of open handles ( >=8192*0.8? ) to start a reminder.

Waiting to be perfected ...

If it is a single-machine multi-instance, just need to add a for loop just fine.

On the mobile phone to install NetEase's mail client, you can achieve the effect of real-time reminders.
