Functional Demonstration


Configure Disk Usage Monitor Service component to monitor the disk usage of 'C drive' on a Windows machine.

Configure the parameters mentioned above and use a Display component to receive the alerts when the Disk Usage Limit exceeds. Configure the Disk Usage Limit as 80% (Disk Usage Limit property value set as 80) and run the event process to find the Disk Usage Monitor window and Display window with the alert (wait for as much time as specified in Monitoring Interval property).
