Monitoring Performance with Dynamic Analyzer

MobileWearable

Dependencies

  • Tizen Studio 1.0 and Higher

Related Info

The Dynamic Analyzer is a performance monitoring and analysis tool for your native and Web applications on a Tizen device or the emulator. The main focus of the Dynamic Analyzer is to analyze your application for potential performance issues, such as high usage of CPU, memory, file, or network operations.

The Dynamic Analyzer is designed to analyze performance issues on your application after development, to help you optimize the application. The following figure shows the basic workflow for how the Dynamic Analyzer works with other Tizen tools:

  1. Develop your application with the Tizen Studio.
  2. Compile and install the application to an emulator or Tizen device target.
  3. Verify the application on the target and fix any functional issues to fulfill the requirements.
  4. Profile the application with the Dynamic Analyzer.
  5. Study the tracing result and fix any performance issues.

Using the various profiling features of the Dynamic Analyzer, you can determine where your application can be optimized further.

Profiling Features

When the Dynamic Analyzer is launched, a feature selection dialog opens. You can select the available features for your profiling based on the selected target profile.

The following table lists the supported features on the Dynamic Analyzer. Every feature is placed onto a specific group (CPU, Memory, File System, Graphics, Network, UI, Synchronization, or Energy) to help you understand the profiling category.

Table: Available features

Group Feature Description Page tab where shown
CPU CPU Usage

CPU Usage

Shows the total CPU usage made by target processes on a system and the CPU usage in percentages. Timeline
Core Usage

Core Usage

Shows the usage of each core on a device (or an emulator) in percentages. The number of series on the chart depends on the number of cores. Timeline
Core Frequency

Core Frequency

Shows the frequency of each core on a device in MHz. This feature is only available on devices, not on emulators. Timeline
Memory System Memory

System Memory

Monitors the maximum and used memory of the system, and the memory used by a process, in KB. Timeline
Process Memory

Process Memory

Monitors a partition of the PSS, 3D, and GEM memory of a process in KB. Timeline
Heap Allocation

Heap Allocation

Records all memory allocations and frees the requested allocations from the executable and shared libraries. This feature shows un-freed allocations (leak candidates). Memory
File System Disk IO

Disk IO

Shows the system I/O events, such as the occurrence of the read/write operations and the number of bytes in them. Timeline
File Analysis

File Analysis

Analyzes file activities, such as open, close, and lock operations, in a separate analysis view. File
Graphics OpenGL ES Analysis

OpenGL ES Analysis

Analyzes OpenGL® (Open Graphics Library) 2.0 and EvasGL information used on a process. It shows detailed OpenGL® API lists, and context, program, and texture information at a particular point in time. OpenGL ES
Network Network IO

Network IO

Shows the number of bytes that the system sends and receives through the network. Timeline
Network Analysis

Network Analysis

Analyzes network activities, such as recv, send, bind, and accept operations, in a separate analysis view. Network
UI UI Event

UI Event

Shows the touch (press, move, release), gesture (distance, movement, angle), and orientation change events. Timeline
Screenshot

Screenshot

Shows a series of screenshot events taken by a user. It can be set to capture a screenshot during each screen transition or at specific time intervals. Timeline
UI Hierarchy Analysis

UI Hierarchy Analysis

Analyzes the hierarchy and details of an EFL-based application using EFL UI objects (Evas, Elementary, and Edje). UI Hierarchy
Synchronization Thread Analysis

Thread Analysis

Analyzes the internal threads of a process and its synchronization operation. Thread
Energy Peripheral Status

Peripheral Status

Shows the on/off state of the Wi-Fi, Bluetooth, GPS, data network, and camera peripherals. Timeline
Power Estimation

Power Estimation

Calculates the power consumption of the CPU, flash, LCD, Wi-Fi, and Bluetooth with an accurate estimation model. Timeline
