App performance test: (III) traffic monitoring

app Performance testing ：（ 3、 ... and ） Traffic monitoring

The flow monitoring is analyzed below ：

• Acquisition process ID Instructions
  adb shell “ps | grep Package name ”
• Acquisition process ID Traffic
• adb shell cat /proc/pid/net/dev
  pid Change to the process obtained in the first step ID

receive It refers to the data received by the current process ,transmit It refers to the data requested by the current process , Flow is the sum of the two
In the end wlan0 representative wifi Upload and download volume identification ! The unit of upload and download is bytes /1024 The conversion KB
Here you can see the number of bytes downloaded 、 Data packets and Number of bytes sent 、 Data packets
rmnet_data0： On behalf of the mobile network

wlan0 These values are initialized 0 Turn on the mobile phone flight mode and then turn it off 0 了
