When launched the NVIDIA Monitor application detects installed ESA-
compatible devices such as CPUs, video cards, memory, system board, and
chassis components. Selecting a component in the interface displays real-
time data for the available operating characteristics of that component. These
characteristics may include voltages, fan speeds, usage, temperatures and
more.
You can customize the NVIDIA Monitor to:
• Choose key performance characteristics to monitor, graph, and log.
• Set reporting intervals and performance thresholds.
• Configure and log user defined events.
• Customize application key strokes.
