As tables increase in size and more and more users come online, it becomes increasingly necessary to fine-tune your database server from time to time.

In the earlier blog, we showed a number of ways to determine the cause(s) of MySQL database performance issues using a couple of built-in tools. With this two blog series, we will focus on monitoring key performance metrics. In part one, we’ll:

• examine the benefits of performance monitoring,

• list the monitoring tools provided by MySQL, i.e.:
