The Status page displays when you log into the FactoryTalk Historian ME web
interface. When working in the FactoryTalk Historian ME web interface, you can re-
access this page by going to Home and clicking Status in the left-side navigation bar.

your browser toolbar to show current status information.
The CPU usage percent listed under the System Status section on the left-hand side
may display a different percent than what is listed under CPU and Processes in the
main window because the CPU usage listed under System Status is updated
periodically while the CPU usage listed in the main window is static. It does not
change once the page is loaded.
