Disk Activity in System Monitor 2.10.1

["Walter J. Mazurowski" <WJMazurowski adelphia net>]

Hi!
	I'm not sure this is the appropriate forum but I originally posted on
fedora-list redhat com about a week ago and have seen no response. I
have been searching for the appropriate forum and found discussions on
System Monitor in the archive for this list.
        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.

        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 partition? 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.
	Thank you in advance for any assistance or direction as to the correct
forum on which to pose this question.
