Description ratundtat 2024-06-16 08:49:00 UTC

Hi dear KDE team,

I want monitoring all my internet speed of whole my local processes.

As like as, i start steam, a http download or any tool what is something loading from internet, then this information is most falling in systemmonitor. At the moment is see speed values of hexchat and firefox, but not for steam (what is needs full band-bright.  in systemmonitor, the field "Download" in the line of the process steam is empty.  

That is why i tried the tool "nethogs". There i can monitoring all processes, with full path and information of the LAN/WLAN adapter.
 
Could you fix this, please?
*And adding: place mouse to this field == little popup for see full path of the process and uses network adapter?
**Perhaps adding: all connected URLs (sorted by process), if it is possible as like as nmap, but much better?   

STEPS TO REPRODUCE
1. starting systemmonitor (gui)
2. select tab: processes
3. take a look in the categories: Download / Upload

OBSERVED RESULT
There will not monitored all internet communications.

EXPECTED RESULT
i need correct information about my internet speeds for every process.

I sometimes have the same problem. It seems like what software is affected changes sometimes. Currently, it works for Firefox but in the past it also did not for that program. The total amount of download speed seems to always work, just there is sometimes nothing shown in the row of any program.

Hi, thanks for reporting that. It's odd. I could repro right away on git-master. In fact I don't see anything under the columns Download, Upload, Read and Write! As a side note, the Network speed widget is working correctly.

Tested a random download in Brave and in Steam.

There was an issue with byte ordering of socket information that's been fixed in 6.4: https://invent.kde.org/plasma/libksysguard/-/merge_requests/403 that was most likely the cause of your issue.

We can still reproduce the issue on latest git-master

- System Monitor > Applications (or Processes)
- Create some traffic in your browser, speedtest.net or whatever
- Look for anything in Download / Upload
- Columns Download / Upload are entirely empty.

 The Network graph in the History tab is correct though as is the Network usage widget grpah. TraceyC could confirm this also.

I wasn't able to reproduce a few weeks ago, but I can reproduce on git master built today on top of Fedora KDE 42, trying both downloading and uploading from my Proton Drive folders.

Thanks for reporting!
