[mrtg] Graphing netware disk usage

Firstly, I apologise if this question has been asked before. I've looked at
what I'm trying to do and if there's an error I just can't see it.
Below is a section of my mrtg.cfg

-----------------------mrtg.cfg
-------------------------------------------------------------
Title[VCH-NA1.SYS]: Disk Space Usage on SYS
Target[VCH-NA1.SYS]:  `/usr/lib/nagios/plugins/check_nwstat 10.5.1.9 -v
VKFSYS | cut -f2 -d =`
Kilo[VCH-NA1.SYS]:1024
AbsMax[VCH-NA1.SYS]:2097152000
MaxBytes[VCH-NA1.SYS]: 1638912
Options[VCH-NA1.SYS]: gauge, nopercent
YLegend[VCH-NA1.SYS]: Free Space
ShortLEgend[VCH-NA1.SYS]: bytes
Legend1[VCH-NA1.SYS]: SYS
Legend2[VCH-NA1.SYS]: 
Legend3[VCH-NA1.SYS]: SYS Peak
Legend4[VCH-NA1.SYS]: 
LegendI[VCH-NA1.SYS]:  SYS:
LegendO[VCH-NA1.SYS]: 
PageTop[VCH-NA1.SYS]: <H1>Disk space stats for VCH-NA1\SYS </H1>
  <p> These graphs track disk space usage on SYS
------------------------End of mrtg.cfg
-------------------------------------

If I execute the command from a bash shell i get


nagios1:/etc/init.d # /usr/lib/nagios/plugins/check_nwstat 10.5.1.9 -v
VKFSYS 
1126912 KB free on volume SYS|KBFreeSYS=1126912;0;0;;
nagios1:/etc/init.d # /usr/lib/nagios/plugins/check_nwstat 10.5.1.9 -v
VKFSYS | cut -f2 -d =
1126912;0;0;;
nagios1:/etc/init.d # 

I was hoping this would get me a log file in my workdir=/var/www/mrtg but
nothing. I get a link on my mrtg web page but obviously no log file means no
.html file. (Before somebody asks why I'm not using snmp, I'll explain that
these are nss volumes so snmp doesn't return the most accurate of figures
were as the check_nwstat command is fairly spot on.)

Is 1126912;0;0;; in the correct format or have I missed something eg it's
delimited by |?


Thanks,
PeteH
