I do this, currently. It goes something like this, on linux. Run from cron,
once a minute:
#!/bin/sh
CLIENT="/usr/bin/gmetric"
/usr/bin/iostat -x 4 2 cciss/c0d0 | grep -v ^$ | tail -4 > /tmp/disk-io.tmp
UTIL=`grep cciss /tmp/disk-io.tmp | awk '{print $14}'`
WRITE=`tail -1 /tmp/disk-io.tmp | awk '{print $9}'`
READ=`tail -1 /tmp/disk-io.tmp | awk '{print $8}'`
IOWAIT=`head -2 /tmp/disk-io.tmp | tail -1 | awk '{print $4}'`
$CLIENT -t uint16 -n diskio-util -v $UTIL -u '%'
$CLIENT -t uint16 -n diskio-write -v $WRITE -u 'wkB/s'
$CLIENT -t uint16 -n diskio-read -v $READ -u 'rkB/s'
$CLIENT -t uint16 -n diskio-iowait -v $IOWAIT -u '%'
and that's all there is to it. replace cciss/c0d0 with the drive device of
your choice.

Subject: Re: [Ganglia-general] Disk I/O in the Linux gmond
Richard,
for Solaris we have {b,l,ph}{read,write} metrics, that would cover
disk-io (not latency).
Nothing has been done for the other platforms in the ganglia
monitor-core.
Have you looked at the repository page?
http://ganglia.sourceforge.net/gmetric/
Entry #39 may be interesting for you.
