As a MySQL database administrator, keeping a close eye on the performance of your MySQL server is crucial to ensure optimal database operations. However, simply deploying a monitoring tool is not enough; you need to know which Key Performance Indicators (KPIs) to monitor to gain insights into your MySQL server’s health and performance.

In general terms, to achieve HA in PostgreSQL, there must be: Redundancy: To ensure data redundancy and provide continuous performance when a primary server fails, multiple copies of the database reside in replica servers. When the primary server fails, a standby server takes over as the new primary.
