error with reading memory usage

[ahumblescientist]

here is what i3status-rust outputs:

sudo ps_mem ouput: (sorry for bad english)

[ammgws]

Hmm, that percentage seems pretty sus. Thought we had fixed memory calcs a while back.

Do you use ZFS?

nope

@ahumblescientist does the value in your status bar match the output of free -g? On my computer free -g and ps_mem report different amounts of used memory. I'm pretty sure ps_mem just doesn't count everything.

@bim9262 no, it says used 2GB, unlike i3status-rs which says that the used is 12GB

[ammgws]

What does htop show?

[ahumblescientist]

@ammgws

[bim9262]

Can you share the format you are using for the memory block?

[ahumblescientist]

@bim9262 im using the default: format = " $icon $mem_avail.eng(prefix:M)/$mem_total.eng(prefix:M)($mem_total_used_percents.eng(w:2)) "

[bim9262]

So you are showing how much is available, not how much is being used

[ahumblescientist]

@bim9262 this is the dumbest i have ever felt to be honest, i rlly didnt notice that

[bim9262]

Haha no worries, glad we got it sorted out

[ammgws]

Possible cause of confusion could be that the percentage shown in the default format string is the total used %.

Perhaps should change

$mem_avail.eng(prefix:M)/$mem_total.eng(prefix:M)($mem_total_used_percents.eng(w:2))

to

$mem_avail.eng(prefix:M)/$mem_total.eng(prefix:M)($mem_avail_percents.eng(w:2))

?

[bim9262]

I think that used/total(used%) would be a better default. :man_shrugging:

[ahumblescientist]

@ammgws yes the avail percent works, but the used dosent work, it outputs 97% used even tho im only using 3GB of 16GB, i was intending to use the avail from the start anyway

I think my total mem usage output is also wrong calculated:

free -g
               total        used        free      shared  buff/cache   available
Mem:              31          11           4           0          15          18
Swap:              1           0           1

[[block]]
block = "memory"
format = " $icon $mem_total_used_percents.eng(w:2) "
format_alt = " $icon_swap $swap_used_percents.eng(w:2) "
