This feature is available on Artica 1.3.080203
This feature display a little progress bar under the disk size progress bar in order to show you the load percentage of this physical disk.
It is important to know if your disk approach it's saturation.
You can have a good CPU response time a good free memory but perhaps your disks are overloaded.
To get information on Artica you need the "sysstat" package that is available on all linux distributions.
For new installation, Artica with setup-* will do it for you.
If sysstat is installed, you will see in the right part of main screen (in the index page) a little progress bar under the main progress bar of your disk.
This progress bar means the percentage of CPU time during which I/O requests were issued to the disk (bandwidth utilization for the disk).
Device saturation occurs when this value is close to 100% and the progress bar is turned to red if the value exceed 90%.
This an example of a disk that will turn to saturation (95% of this case).
This is an example of a free disk utilization (9% in this case)
For users that upgrade to newest Artica version, you need to install sysstat:
For debian/ubuntu users
apt-get install sysstat
For CentOS/Fedora users
yum install sysstat
For OPenSuSe users
zypper install sysstat
