Complete Guide to Monitoring Network Usage on iOS Devices with Keymob

1. Feature Overview

Keymob provides professional network performance monitoring for iOS devices, supporting real-time tracking of global network bandwidth usage (including upload/download traffic), precise statistics on packet send/receive counts, and visualizing network load fluctuations. This feature is suitable for the following scenarios:

• Detecting background traffic leaks in apps
• Analyzing real-time game transmission performance
• Identifying network congestion caused by high concurrency requests

2. Step-by-Step Process

2.1 Entering the Network Monitoring Interface

• Connect Device: Connect the iOS device to Keymob via USB. Using Wi-Fi for the connection may include communication data between the phone and computer, resulting in inaccurate data.
• Navigate to the Module: Click on the left menu bar “Performance Charts” → Select the “Network Monitoring” tab

2.2 Enable Monitoring Metrics

• In the top-right corner of the interface, check the following metrics:
  • “Network Monitoring”: Activates traffic statistics

2.3 Start Data Collection

• Click the “Start” button, and the tool will capture network activity in real-time
• Perform the target actions on the iOS device (e.g., start video streaming, file uploads, etc.)

2.4 Data Analysis

• Real-Time Graph:
  • Blue Curve: Download traffic (unit: KB/s)
  • Green Curve: Upload traffic (unit: KB/s)
• Data Panel:

  Metric	Description
  Total Data Received	Total downloaded data in the current session (MB)
  Total Data Sent	Total uploaded data in the current session (MB)
  Packets Received/Second	Average number of network packets received per second
  Packets Sent/Second	Average number of network packets sent per second

3. Traffic Unit Conversion

• 1MB = 1024KB = 1,048,576 bytes
• Traffic statistics do not include TCP/IP header overhead (actual consumed traffic is approximately 3-7% higher)

4. Case Studies

Case 1: Abnormal Traffic on Game Login Screen

• Phenomenon: Continuous 20KB/s upload traffic when idle
• Troubleshooting:
  1. Mark traffic period → View process monitoring and find a continuously active SDK
  2. Identify that the SDK had not optimized its heartbeat interval
• Optimization: Adjusted heartbeat interval from 10 seconds to 60 seconds

Case 2: Video Playback Stuttering Analysis

• Phenomenon: Stable download rate but frequent buffering
• Troubleshooting:
  1. Found that packet retransmission rate was >15%
  2. Confirmed severe network jitter using latency metrics
• Optimization: Enabled adaptive bitrate switching algorithm
