Do you struggle to improve system performance or to find root cause that makes system abnormal?
Guider is made to measure the amount of system resource usage and to trace system behavior.
You can analyze your performance issues effectively with this tool.

Guider pursues characteristics as below.

  1. Easy to use: just run without any setting and package installation
  2. Measure correctly: count, time in from us, size in from byte
  3. Provide all features: enough functions for experiment and analysis
  4. Submit the report in detail: show as much information as possible

It usually supports all platforms based on the Linux kernel as shown below.

  • Android
  • distro (Ubuntu, CentOS, RHEL, Linux Mint, Arch Linux, ...)
  • webOS

How to use

Input a command as below to start tracing for all threads.
    # ./guider.py record -a
And input 'Ctrl + c' on keyboard to finish tracing.

Input a command as below to start monitoring for all processes.
    $ ./guider.py top -a
And Input 'Ctrl + c' on keyboard to finish monitoring.

Input a command as below to see more instructions.

Visit a below link to see the output of guider.
- https://github.com/iipeace/guider/wiki

Requirement

- linux kernel (>= 2.6)
- python (>= 2.7)

Build & Installation

If you can run 'pip' on your system then just input a command as below
    # pip install guider
Then you can use 'guider' command

Otherwise, download the source from https://github.com/iipeace/guider
Then you can just run "guider.py" but it is a little bit heavy 
If you want to run guider lightly then input a command as below
    # make && make install
Then you can use 'guider' command
