Which top metrics should you monitor for MySQL databases?

As tables increase in size and more and more users come online, it becomes necessary to finetune the database server from time to time. The secret to knowing what adjustments to make is to perform regular monitoring. Most databases offer dozens, if not hundreds, of performance metrics that one can assess.

As a database administrator, the top priority is to keep the databases and dependent applications running smoothly at all times. The best weapon is the careful monitoring of key performance metrics. In a perfect world, one would want to be up-to-date regarding every aspect of the activity of the database. One would want to know how many events occurred, how big they were, when they happened, and how long they took to complete.

There is no shortage of tools that can monitor resource consumption, provide instantaneous status snapshots, and generate wait analysis and graphs. The challenge is that some metrics can be expensive to measure, and perhaps they can require much work to analyze.

Read the 33-page whitepaper "Top Metrics to Monitor in MySQL Databases" by Shree Nair to learn about monitoring key performance metrics. In particular, learn how to:

  • Examine the benefits of performance monitoring.
  • Outline the primary performance metric categories.
  • List the monitoring tools provided by MySQL:
  • Server variables
  • Performance schema
  • Sys schema
  • Monitor transaction throughput
  • Monitor query execution performance

Further, this whitepaper narrows down the field to the performance metrics that provide the most value for the effort. Also, this whitepaper presents some tangible ways to capture and study them. It is by tracking the most useful metrics and reviewing them in the most informative ways that one balances paranoid over-monitoring and unforeseen firefighting crises. This whitepaper focuses on monitoring database connections and buffer pool metrics.
