A python based Apple instruments protocol，you can get CPU, Memory and other metrics from real iOS devices

link: https://testerhome.com/topics/27159

中文文档

Java link: https://github.com/YueChen-C/java-ios-device)

pip :

pip install py-ios-device

python version: 3.7 +

Instruments：

  • Get system Memory and CPU data
  • Get processes Memory and CPU data
  • Get FPS data
  • Get network data
  • Set the device network status. eg: 2G, 3G ,100% Loss
  • Set the device behaves as though under a high thermal state
  • Monitoring app start、exit、background
  • Launch and Kill app
  • Run xctest. eg: WebDriverAgent
  • Dump core profile stack snapshot
  • Analyze the core profile data stream
  • Get Metal GPU Counters
  • Get App Launch Lifecycle

Other

  • Profiles & Device Management. eg: Install and uninstall Fiddler certificate
  • Get syslog
  • Get crash log
  • Get the captured packet traffic and forward it to wireshark
  • App install and uninstall
  • Get device battery
  • Set simulate-location options

Usage：

pip :

> pip install py-ios-device
> pyidevice --help
> pyidevice instruments --help
