Do you occasionally see a problem in your MySQL database, or that you suspect is caused by your MySQL database, but you can't diagnose it because you aren't looking when it happens? This is a very common reason for problems to continue happening for weeks or months before they are solved.
Baron Schwartz explains how Percona's open-source tools make troubleshooting easier and faster. These tools are proven by years of production use, and have enabled accurate diagnosis of systems that had been causing problems for many months, or were even dismissed as unreproducible. They help the server administrator capture and interpret the diagnostic data you need to dramatically shorten the troubleshooting cycle time, leading to increased uptime and better quality of service.
