bug: Displaying wrong usage of RAM (WAM) #178

Closed kristiyanivanovx closed 2 years ago

kristiyanivanovx commented 2 years ago

I think the RAM / WAM usage is calculated incorrectly, compared to other fetch solutions. You may want to take a look at this issue and the pull request:

https://github.com/dylanaraps/neofetch/pull/391 https://github.com/KittyKatt/screenFetch/issues/386#issuecomment-249312716

On my machine, uwufetch displays WAM 3067 MiB/7654 MiB, while neofetch displays Memory: 4189MiB / 7654MiB.

Excuse me if this particular issue is already addressed and you have chosen to calculate it differently. Cheers.

After looking for ram usage in some programs: The screenshot I thought that a proper way to get ram usage on linux does not exist. I will try to push an update that gets ram usage without free (reading /proc/meminfo as the comment that you linked says, because it should be faster than using an external program, I think), and if no one complains about that, it will be the "final" way to get ram.

GNOME's system monitor measures RAM usage in MB/GB, not MiB/GiB which is how most other CLI based system monitors, including free measures data by default. This might explain why the values are significantly different.

Changing the unit in the preferences of gnome system monitor makes no difference: it still shows ~600MiB more than the others.

After an inactivity period of 76 days, I am pretty sure that a solution to this problem does not exist: there are lots of different ways to get memory usage on linux, but every one of them has a different result. So how can we decide which one is right? Well, that's simple: we don't. They are all valid.

Maybe in future I'll add a way to configure what values to include in the memory calculations.

At the moment I'm closing this issue, but if someone finds a document about a "standard"/"official" way to get mem usage, I'll be happy to reimplement it here.

Edit: The issue will stay pinned.
