1. INTRODUCTION:

Cross-platform scripts developed in Python3 for fetching and providing runtime CPU, RAM, PIDs, OS and system information.

1.1 Audience:

Quite simply, everyone. From a student to a system engineer, from a software developer to an IT enthusiast. It’s developed with the thought to be easily used by anyone :wink: .

2. Pre-requisites:

2.1. Python3 * Python 3 is easily available for free to download, install and use on windows & *nix platforms. If you do not have Python 3 installed on your machine where you require the use or execution of these scripts, please feel free to use the following methods:

• Windows: Python3.7.0 is the latest major Python release that can easily be downloaded and installed. Note: Python 3.7.0 was the major release at the point of this development. Feel free to use a newer 3.x Python version if you desire.

• Ubuntu LTS OS’s: Pre-installed on Ubuntu LTS OS’s i.e. 16.04 xenial & 18.04 bionic.

2.2. psutil library

• Windows: You can easily install psutil library using command prompt i.e. cmd. Just open cmd, and type in pip install psutil .

• Ubuntu LTS OS’s: Just run the install_pre-reqs.bash script and it will take care of that for you.

• Note: psutil library was developed by Giampaolo Rodola. It is a cross platform library for system level information. Kudos to Giampaolo !!!

3. Tested on:

1. Windows Operating Systems (i.e. 7, 8, 8.x & 10). Works on Windows Server editions too.

2. Ubuntu 16.04 & Ubuntu 18.04

4. Usage:

Utilizing the library is pretty simple. All you need to do is execute the main_system.py file. Assuming that you have already downloaded either the zip/tar or cloned the project already. Following two sections will cover the execution process.

• Windows:

  1. Either Download or clone using git clone https://github.com/Tech-Overlord/system-info
  2. Open a cmd window.
  3. Perform cd into the directory where the extracted archive or project is cloned in. For instance, if you have extracted or cloned into D:\ drive. Do cd D:\system-info
  4. Now, change directory into the sysinfo package i.e. cd sysinfo
  5. Current directory should be: D:\system-info\sysinfo
  6. Execute main_system.py with the following commands: python main_system.py
  7. All done. That will print a detailed output as can be seen below:

       D:\system-info\sysinfo>python main_system.py
                 
       System & OS level details below:

       Processor Name: Intel64 Family 6 Model 78 Stepping 3, GenuineIntel
       Machine Name on Network is: DESKTOP-MS0CV80
       Machine Type is: AMD64
       System platform type is: win32
                 
       RAM details below:
                 
       Total memory is: 8481.492992 MBs
       Current available memory is: 1897.357312 MBs

• Ubuntu:

  1. Change to user’s home directory, for e.g. by entering the following command: cd ~
  2. Either Download using wget https://github.com/Tech-Overlord/system-info/releases/download/v1.0.1/system-info-1.0.1.tar.gz or clone using git clone https://github.com/Tech-Overlord/system-info
     • If cloned, simply change into the root directory of the cloned project and then into the sysinfo folder, for e.g. cd ~/system-info/sysinfo/
       • Do chmod +x *
     • If tar was downloaded using wget. Extract it using the commands: tar -zxf system-info-1.0.1.tar.gz and then cd into extracted directory right down to sysinfo package, for e.g. if the extracted directory is system-info-1.0.0, then do cd system-info-1.0.1/sysinfo
       • Do chmod +x *. This will ensure that the scripts have execute permissions.
  3. Execute main_system.py file with the command: python3 main_system.py
  4. This will print a detailed output as shown below:

       vagrant@ubuntu:/vagrant/sysinfo$ python3 main_system.py

4.1 Data Measurement Unit

Data measurement units can be classified into the following:

1. Bit - It is the smallest unit of computer data measurement. Only has the value of 0 or 1, which correspond to electronic values of on or off.
2. Byte - Contains 8 bits and enough information to form and store at least a single ASCII character, for e.g. ‘a’.
3. KiloByte - Contains about 1024 Bytes.
4. MegaBytes - Contains about 1024 KiloBytes.
5. GigaBytes - Contains about 1024 MegaBytes.

There are larger units of data measurement as well. Feel free to google and read about them. For now, I have only mentioned a few units used in this project.

Data Measurement unit(s)	Bytes
KiloByte (KB)	1024 Bytes
MegaByte (MB)	1024 KiloBytes
GigaByte (GB)	1024 MegaBytes

main_system.py currently will output everything using ‘MB’ as a data unit. However, you can eaily modify it to any of the below mentioned data measurement units. To do so, follow the following steps:

1. Open ‘main_system.py’ into any editor of your choice. It contains the following code:

     #! /usr/bin/env python3
       
    import ram_kb
    import ram_mb
    import ram_gb
    import sys_sw_hw_info
    import variables_data
    import pid_info
       
       
    # Assigning a variable for the purpose of specifying which data measurement function is to be used.
    data_measure = variables_data.megabyte
       
    # Printing system, os, architecture level information using the function system_details in sys_sw_hw_info module.
    print('\nSystem & OS level details below:\n')
    sys_sw_hw_info.system_details()
    print()
       
    # Printing IP address using the ip_addr function within the ip_address module.
    # ip_address.ip_addr()
    # print()
       
    # Printing RAM details by using if/else statements so that the data measurement is in accordance to value of
    # data_measure variable
    print('RAM details below: ')
       
    if data_measure == variables_data.kilobyte:
        ram_kb.ram_specs()
    elif data_measure == variables_data.megabyte:
        ram_mb.ram_specs()
    elif data_measure == variables_data.gigabyte:
        ram_gb.ram_specs()
    else:
        print('Data Variable messed up! please check the code.')
       
    # Listing all of the current processes using process_info function in pid_info module.
    print('\nCurrent process details below: \n')
    pid_info.processes_info()
   

2. To modify the data unit type, change the value of variable data_measure at line 12. For example, if you want to switch it to gigabyte, then modify from data_measure = variables_data.megabyte to data_measure = variables_data.gigabyte.

3. That’s all! Just run main_system.py again and you should see the data measurement unit related output in gigabyte. Feel free to change data measurement units to your desire.

Note: Data measurement types have been defined in variables_data.py.
