[mrtg] Modifying SNMP Input Values

Hi All,

    Just a quick one. I am monitoring the disk usage on some of our Win2K
systems however Microsoft only exposes the number of blocks used on a device
as opposed the bits/bytes, etc. Luckily they also expose the block size in
bytes as a seperate OID. I am currently using factor[] to modify values at
the base of the graph however I want to know if there is anyway of applying
this "factor" to the graph as well? because at present the values at the
bottom reflect the correct value I want (~10.8GB) however the graph displays
the number of blocks (~2.7GB) which is the block size not the byte size I

Here is an excert from my config.

Options[^]: nopercent, growright
# Current Disk Usage
# Disk Size (in blocks): .
# Total Bloacks Used:  .
# Block Size:   .
. at xxx.xxx.xxxxxx
MaxBytes[mwsydstl1_disk_usage]: 36372967424
Factor[mwsydstl1_disk_usage]: 4096
Options[mwsydstl1_disk_usage]: gauge
Title[mwsydstl1_disk_usage]: Disk Usage -- MWSYDSTL1
PageTop[mwsydstl1_disk_usage]: <H1>Disk Usage -- MWSYDSTL1</H1>

Anyhelp would be greatly appreciated.
