Process Status Analysis – the first steps

I am pleased to announce my first cross-platform and open source project, the Process Status Analysis tool, available on GitHub.

The Process Status Analysis (psa) version 0.2 is available for Windows and Linux (Debian derived / Ubuntu tested) Operating Systems.
Download: psa for Ubuntu Linux x64 (980 downloads)
Download: psa for Ubuntu Linux x86 (612 downloads)
Download: psa.exe for Windows x64 (582 downloads)
Download: psa.exe for Win32 (595 downloads)

You may wonder why I did it or what it brings new. Well, I did it for fun, in my spare time and I will continue improving it when I’ll find a time to do it.

The project is written in modern C++ using idioms from the C++ 1x standards. Even if initially was done as a C++ for Windows only, during the past days I managed the port of it for Linux using Visual Studio 2017’s project templates and a connection via SSH.
In general, the source code base is similar, differing just by OS specific stuff.

In case you want to find out more about how to develop C++ Linux projects from the best development tool (imho), Visual Studio, you can find more information on Visual Studio development team blog.

Related to this psa project, the Linux version requires libprocps4-dev library in order to build.

The main reason for starting this project was that I wanted to know what’s the total memory amount used by my Chrome browser. I know it uses a lot of resources but not that much… 🙂

Even if my preferred processes analysis tool, the Process Hacker offers a lot of processes administration possibilities but it didn’t provide what I want, so I decided to enjoy a bit.

Sample – Google Chrome processes in Process Hacker tool

So, what I achieved by psa.exe was something like:

C:\Windows\system32> psa -o chrome
PID [896] chrome.exe 237.5234 MB
PID [1496] chrome.exe 87.6875 MB
PID [2388] chrome.exe 166.5000 MB
PID [5860] chrome.exe 3.1211 MB
PID [7336] chrome.exe 273.2188 MB
PID [8444] chrome.exe 68.0508 MB
PID [8624] chrome.exe 63.3945 MB
PID [9180] chrome.exe 296.9766 MB
PID [10600] chrome.exe 292.6289 MB
PID [12352] chrome.exe 182.5977 MB
PID [13688] chrome.exe 2.3555 MB
PID [14052] chrome.exe 73.1875 MB
PID [16200] chrome.exe 211.9805 MB
PID [17284] chrome.exe 55.7148 MB
PID [18036] chrome.exe 208.6680 MB
PID [19012] chrome.exe 457.2305 MB
PID [19312] chrome.exe 143.4766 MB
-----------------------------------
Total used memory: 2824.31 MB

A bit too much in my humble opinion…
The features this tool offers includes:

Get all processes loaded in memory information

I case you want to have a snapshot of all the processes loaded in the OS’s memory you can have it with.

psa -a

Get process only used memory

With psa.exe you can reach the used memory by a specific parameter -o after the process name or at least a part of it’s name.

psa -o chrome             // find how much memory uses your Chrome!   o_O

Currently, there is no string replace ‘*’ but it’s ongoing.


Print processes tree

Storing the processes’ data within a generic tree done by me I took the decision to print the processes tree output, in a similar way there is in Windows with tree.exe tool or on Linux in pstree or even htop.

./psa -t
./psa -t 1034

Top most “expensive” processes

In case you want to see what are the most expensive processes within your operating system you can achieve it with:

psa -e 20

or simpler “psa -e” in case you’re sure you want top 10 expensive processes (the default value).

Redirect output to a file

From the standard output the information can be easily redirected to a file.

c:\> psa -t > windows_processes_tree.txt
# ./psa -t > linux_processes_tree.txt        

Kill process feature

This feature was not implemented yet but in case we need it we can be done it easily with the existing tools on the target OS (ex. Task Manager, Process Exporer/Hacker, pskill.exe for Windows or the combination ps + kill on LInux).

Simple Pictures Unifier 1.1 application is up!

At the beginning of this year, I have launched an application that helps you to organize the pictures of your important moments. The application helps you especially if you have photos from different sources (different cameras of friends) and you want to have a fluent images story.

From the moment I have launched the first release until now I made up to 12GB pictures (3200+ pictures of 10 MB) and honestly I never found time in order to organize the pictures. Always I said that I will complete my application and finally I found time to implement export by date time folders and so on.

Simple Pictures Unifier 1.1 allows merging and exporting pictures in one folder or in date time folders. The application comes with a better user-friendly experience and few internal improvements.
The Start Export button launched a new wizard dialog that allows the selection of the preferred export method.

Export Wizard dialog

If the user chooses the default export to date time folders the Export wizard window shows a list with detected time folders.

Selecting Finish button the pictures merging is realized and the files are copied to the destination folders. If the user wants to abort the export process it can just press Stop button or close the application with now damages.

Feel free to add comments, suggestions or bugs reports. Any constructive feedback is sincerely appreciated.
