Hi!
I have been using FC4 on a dual boot 2.4 GHz Pentium 4 system, since a
few days after it was released. I am current and up to date with all the
latest updates.
/home/wjmazurowski >uname -a
Linux wjm-fedora-1 2.6.13-1.1526_FC4 #1 Wed Sep 28 19:15:10 EDT 2005
i686 i686 i386 GNU/Linux
I have added the Gnome System Monitor (2.10.1) application to the
bottom Panel, Further, I configured it to show all the monitor
capabilities (Processor, Memory, Network, Swap Space, Load Average,
Disk). The system has one Western Digital 80GB IDE disk drive
called /dev/hda partitioned as follows:
/home/wjmazurowski >sudo parted /dev/hda print
Disk geometry for /dev/hda: 0.000-76319.085 megabytes

My swap file is on /dev/mapper/VolGroup00-LogVol01 which does not show
up in the df.
My problem/question is although all the other graphs seem to be working
as expected I never see anything at all on the "Disk" graph. Floating
over it, even when the disk is busy and thrashing away, I see "Disk 0%
in use".
I have played with the System Monitor "Preferences" to see if something
was set wrong. The current settings are System Monitor Width 50 pixels,
System Monitor Update Interval 500 milliseconds. The colors are for Read
- Blue, for Write - Red and for Background - Black.
The settings seem to be right for all the other graphs. They all seem
to show activity in proportion to what I know is going on in the system.
Except for the Disk. It is always Black and 0% in use. Even when I do an
"ls -R /" which I would think should turn the graph almost solid Blue,
given my color settings.
Is System Monitor/Disk graphing my disk usage? Is it connected to the
wrong disk? Can it monitor only 1 disk? In creating this e-mail I was
testing my "ls -R" comment and noticed that I got a small blue block
approximately 1/3 the height of the 50 pixel graph/panel when I did an
"ls -R /media/windows-share". This is the first time I have ever seen
anything in the Disk graph. Is there some config file somewhere pointing
the disk monitor at /media/windows-share? Can I configure it to monitor
all partitons on the whole hard drive, that is, can it be set-up to
total all reads and writes from/to (/, /boot, /home
and /media/windows-share) and graph the total disk activity? That would
be the Total disk activity on /dev/hda. If that is not possible, how can
I change it so that it monitors the disk activity
to /dev/mapper/VolGroup00-LogVol00 (or /), which for my current purposes
is more important to me then the activity to /media/windows-share.
