MySQL performance monitoring tools

There is always a need to monitor the performance of database servers. For this purpose, there are many tools available that make it easy to monitor MySQL servers and performance. Most of them are open source and free, and some provide a GUI. The command-line tools are more powerful and the best to use, though it takes a little time to understand and get used to them.
