MySQL Monitoring

[Vonng]

We already have PostgreSQL monitoring. Why not monitor existing MySQL instance either?

Since we need that during Migration from MySQL to PostgreSQL. 😊

We already have MySQL exporter for that purpose. We can organize MySQL monitoring targets as PGRDS.

To achieve that:

• Add mysqld_exporter to repo_packages
• New playbook mysql-monitor.yml to deploy and register existing MySQL
• Dashboards for MySQL instances (MySQL Overview/Cluster/Instance/Database)
• Local Testing Environment for Example MySQL.
