You're reading the code correctly. The problem is you cannot configure
it currently.
The problem I ran into is that I haven't found a way of detecting what
metric is reported in the "df" output that the client reports. Here's
an example:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 99511580 11417684 88093896 12% /
Now, it's ease to figure out that there's 12% used on my / filesystem;
even without the "Use%" column, I could just calculate
(100 x 11417684) / 99511580 = 12
But how can I tell what metric is used for "99511580" and "11417684" ?
The heading does say "1K-blocks", but that varies quite a bit between
the operating systems. At worst, it could be "disk blocks" - often 512
bytes, but one never knows.
Configuring a limit of "yellow at 2 GB free" requires that Hobbit can
interpret the absolute values reported by the client, not just the
relative amount of free space. I don't know if there's a good way of
doing that, except to embed (more) knowledge about the various df's
into Hobbit. And I'm not terribly keen on doing that.
