In one aspect, a system for correlating application performance data with hardware performance data via heat maps is disclosed. The system includes: a processor; a memory; and one or more modules stored in the memory and executable by a processor to perform operations. The operations include: receive data associated with monitored applications and hardware; identify application performance data and hardware performance data from the received data; generate interactive heat maps of the application performance data and interactive heat maps of the hardware performance data; provide a user interface for displaying the generated heat maps; and display, through the user interface, the generated heat maps of the application performance data and the generated heat maps of the hardware performance data using a common time scale.
