Hi,
This is another trick you can do if you use unix as MRTG server. Instead of
specifying an OID on Target line, call a unix script from Target line. I
just wrote it and it works. In this script only the second value is
multiplied.

<<<< CUT HERE >>>>>>>
#!/bin/sh

# This script is used by MRTG, it is specified on Target line of .cfg file
# $1 must be IP address of target (Windows NT server)
# $2 must be a community name of target (Windows NT server)
# This script returns four lines
# line 1: memory used on windows NT server in bytes
# line 2: total memory installed in Windows NT server in bytes
# line 3: system up time
# line 4: system name and IP
# For more info consult config.htm

# this script requires that following is installed
# on a target Compaq Windows NT server:
# - Teleserve perfm.bat
# - Compaq Insight Manager client

# BEGIN ============
# Memory used
# This is an OID installed with Teleserve perfm.bat
snmpget $1 $2 .1.3.6.1.4.1.311.1.1.3.1.1.7.2.0 | cut -c35-50

# Total RAM installed in this computer
# Variable returned by Insight Manager OID is in kilobytes,
# it has to by converted to bytes, ie multiplied by 1000
let RAM=`snmpget $1 $2 .1.3.6.1.4.1.232.1.2.3.2.0 | cut -c29-50`*1000
echo $RAM

snmpget $1 $2 system.sysUpTime.0 | cut -c22-70
echo -n `snmpget $1 $2 system.sysName.0 | cut -c20-45 `; echo -n " "; echo
$1
# END ==============

Is it possible to make other operations than additions?

Some 1:public at swtichIP / 2:public at swtichIP * 1234 for example?
