Device/Application Vitals

Device Vitals

The vitals feature collects useful performance data directly from the device in real time. Performance data includes network, CPU, and memory usage (model specific), which measures general device performance and determines how efficient an application is at using resources.

Application vitals

It is also possible to collect application-specific vital measurements from mobile devices. Vitals will be separately collected for all of the selected services.

Available application vitals:

  • For Android: Memory Used, CPU Used, and CPU Kernel. CPU vitals are only supported for Android version 7 and earlier.
  • For iOS (8.0 and up): Memory Used, and CPU Total.

Available vitals per platform

The following table describes which data is collected and supported per platform.

Vital Description Android iOS
CPU Kernel Percentage usage of CPU by the operating system Yes Yes2
CPU Total Total CPU Usage Yes Yes1
CPU User Percentage usage of the CPU by the operating system Yes Yes2
Memory Cache Ram memory that holds frequently used data to increase processing power Yes Yes
Memory Free Unused memory Yes Yes
Memory Used Used memory Yes Yes
Network in data Bytes received from the mobile network Yes Included in "Network total in"
Network out data Bytes sent to the mobile network Yes Included in "Network total out"
Network in Wifi Bytes received from the wireless network Yes (OS Version earlier than 7) Included in "Network total in"
Network out Wifi Bytes sent to the wireless network Yes (OS Version earlier than 7) Included in "Network total in"
Network total in Bytes received from either the wireless or the mobile network No Yes
Network total out Bytes sent to either the wireless or the mobile network No Yes
The following notes apply to devices running iOS 11.0:
1. The reported usage is the sum of all CPU cores in the device. For example, an iPhone8+ (that has a "six-core CPU design with two performance cores that are 25 percent faster and four efficiency cores that are 70 percent faster") could show a value up to 600%.
2. Due to changes in the Apple API for iOS 11.0 these vitals are no longer supported.
