[mrtg] Target with aritmetic expression not working

[Pablo Gestido]

Hi:
I am trying to use mrtg (2.12.2 on Windows NT Workstation) to monitor W2003
server memory.
The server has 512 Mb memory, so I made the following mrtg.cfg file (this is
one portion of it)

#####  Memory 512 Mb = 536870912 bytes

YLegend[10.0.0.79.bytes-mem]: Bytes
WithPeak[10.0.0.79.bytes-mem]: ymw
Options[10.0.0.79.bytes-mem]: growright,gauge,nobanner,noarrow
Target[10.0.0.79.bytes-mem]:
(.1.3.6.1.2.1.25.2.3.1.6.4&.1.3.6.1.2.1.25.2.3.1.6.5:comunity at 10.0.0.79) *
(65536)
##Target[10.0.0.79.bytes-mem]:
.1.3.6.1.2.1.25.2.3.1.6.4&.1.3.6.1.2.1.25.2.3.1.6.5:comunity at 10.0.0.79
MaxBytes[10.0.0.79.bytes-mem]: 536870912

LegendO[10.0.0.79.bytes-mem]: Virtual Memory:
PageTop[10.0.0.79.bytes-mem]: <H1>Memory Utilization</H1>

The problem is that I get the graph attached form it  (it is not getting any
value).
If I change the target line in the mrtg.cfg and use ..

Target[10.0.0.79.bytes-mem]:
.1.3.6.1.2.1.25.2.3.1.6.4&.1.3.6.1.2.1.25.2.3.1.6.5:comunity at 10.0.0.79

it graphs everything OK (but int # of pages - 64k instead of bytes)

I hope anyone can help me to get the arithmetic expresion work

TIA

Pablo
