# getPerformanceData

Get performance data for a specific application. Returns system state information like cpu, memory, network traffic, and battery. Use `getPerformanceDataTypes()` to find available data types.

> **Note:** Falls back to the deprecated Appium 2 protocol endpoint if the driver does not support the `mobile:` execute method.
