Proxmox VE 4.2 RAM chart shows 3-4 GB more than real.

Good afternoon.
The graph shows the RAM is greater than in reality.
Please fix it in the new version.

Hi,

if you look closely you see the difference in units:
the top one is "GiB" meaning gibibyte (one gibibyte is 1024 Mebibyte and so on)
the bottome one is "GB" meaning Gigabyte (one Gigabyte is 1000 Megabyte and so on)

for more information see for example
https://en.wikipedia.org/wiki/Binary_prefix

the reason why we show it this way, is that there no simple (at least we do not know one) way to show the binary prefix units in the graph,
without having weird scaling in the legend (instead of 1GB, 2GB, 3GB, we would have 0.98GiB, 1.95 GiB, and so on)

this way each information is correct

oO, I understood. Thank's.

Why not be consistent and show GB in all cases?

 

[dcsapak]

i would rather show GiB everywhere because it is the more used Unit (like you buy 32GiB Ram and not 34.36GB) , and we always displayed the values this way
(it just was both named GB previously, so the top one was actually wrong)

sadly i have not yet found a way to make it look good in the graph (but it is on my todo list)

I suggested using GB because of the mention that it was difficult to do GiB on the graph.

In fact, either one would be good as long as it is consistent.
