The vitals feature collects useful performance data for an open device (default) or the selected application (not supported by all devices), in real-time. If you have several devices open, you can collect vitals for each of them. For each device, the vitals feature collects the vitals that the specific device supports.

You can view this information in the UI or download it as a .csv file for use in any spreadsheet program, such as Microsoft Excel. Performance data includes network, CPU, and memory usage (model specific), all of which measure the general performance of the device or the application and determine how efficiently an application uses resources.

You can select any of the following graphs to display (if supported by the device):

VitalDescription
CPU KernelThe percentage usage of CPU by the operating system
CPU TotalThe total CPU Usage
CPU UserThe percentage usage of the CPU by the application
Memory CacheThe RAM memory that holds frequently used data to increase processing power
Memory FreeThe unused memory
Memory UsedThe used memory
Network In - TotalThe bytes received from either the wireless or the mobile network
Network Out - TotalThe bytes sent to either the wireless or the mobile network
