This chapter describes the Database File I/O and Lock Waits reports.
These reports identify I/O hot spots and lock wait contention in
your application using the
sys schema, thereby
enabling you to tune the performance of your queries.
The Database File I/O requires the MySQL
schema, which is supported on MySQL 5.6 and 5.7, only.
This graph is displayed only if a MySQL instance is selected in the All Targets drop-down menu.
