[SOLVED] admin console disk stats graph

[padraig]

Hi All,
my disk stats don't seems to make much sense

e.g.

df -kh
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              66G   12G   52G  19% /
/dev/sdb1             1.1T  101G  903G  10% /DISK2

the disk available(in blue) should be ~80% for /dev/sda1 an ~90% for /dev/sdb1
is this normal or am i misinterpreting the graph
TIA

but my graphs show:

You are not alone

I've got the same behaviour (nutty graphs and not true disk space values) on all the setup I've made/seen (mine, customers, etc).

Maybe it's just how i look at it...I don't see a whole lot wrong-if you discount percentages and the total size
isnt' sda1 have 53G free? -it shows that in your graph with the blue level....
same for sdb1 903gb-and the graph shows 0.9 m (so it's on a 1TB scale)

Granted it would be nice if the graphs scaled to the actual size of the drive-so you could make use of percentages...but it does acruately show remaining free space
They do need to fix the labels:
53 becomes K
and 903 becomes 0.9 M
it is slightly confusing

Thanks Klug,

opened a bug on this
Bug 17303 - admin console disk stats graph

[Klug]

It's not a unit (M vs K vs other) problem, it's a graph problem.

Graph does not start from zero (for padraig's sdb1, it start at 800 MB).
That's why it's so difficult to understand/read.

Comment and vote added to the bugzilla.

Thanks mmorse,

I get it now we are just looking at the top of the graph

ya it is a bug...but not one people tend to get worked up over
