[mrtg] monitor disk IO

[Leonardo Rodrigues Magalhães]

    Hello Guys,

    I have some Red Hat 9 Linux servers, some with one IDE disk, some with 2
IDE disks and some with IDE/SCSI disks.

    What I need is to monitor the IO usage per device or even better per
partition (no RAID is involved). I need to graph blocks in/blocks out, KBs
read/write, etc etc. I was looking the sysstat package, which has some
applications that seems to give me some informations like this. But I
couldnt figure out how to feed mrtg with those informations.

    Question is: is there any scripts or HOWTO or some link that you could
point me to help me getting this work ?? As mrtg is running in the same
machine I wanna to monitor, there's no problem on running perl scripts or
something like that. I DONT need a SNMP solution ...

    Thanks for the replies,
    Leonardo Rodrigues
