Usage
The Usage option in Cloud Intelligence dashboard provides a way to collect resource usage metrics, such as the CPU, RAM, disk space, disk I/O, and network I/O. There are two prerequisites, however, for being able to collect usage information:
The virtual machines for which the usage information needs to be collected must be tagged
Capacity and utilization collection must be enabled
To start viewing the usage data, select Cloud Intelligence and then select Usage. In the dialog box that appears, select a date for which to show the usage data under Date, the period (either Day or Hour) under Period, the tag category, and finally the tag entry itself.
