Memory Usage Monitor on Linux/SunOS Servers

ok, so i'm trying to write a shell script (not perl) that monitors memory usage on a server. but i'm confused as to what fields exactly determines that yes, memory is low on a particular server.

it sounds simple enough, but it really isn't. what do I look for in the field below?

Code:
[hostname:527] 
[hostname:527] snmpwalk -v2c -c bla@$AF s54.jabla.net UCD-SNMP-MIB::memory    
UCD-SNMP-MIB::memIndex.0 = INTEGER: 0
UCD-SNMP-MIB::memErrorName.0 = STRING: swap
UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 2040212 kB
UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 2036260 kB
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 8314956 kB
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 302620 kB
UCD-SNMP-MIB::memTotalFree.0 = INTEGER: 2338880 kB
UCD-SNMP-MIB::memMinimumSwap.0 = INTEGER: 16000 kB
UCD-SNMP-MIB::memShared.0 = INTEGER: 0 kB
UCD-SNMP-MIB::memBuffer.0 = INTEGER: 203980 kB
UCD-SNMP-MIB::memCached.0 = INTEGER: 4031680 kB
UCD-SNMP-MIB::memSwapError.0 = INTEGER: noError(0)
UCD-SNMP-MIB::memSwapErrorMsg.0 = STRING: 
[hostname:528] 
[hostname:528]

NAME
installsieve - user utility for managing sieve scripts SYNOPSIS
installsieve DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server. OPTIONS
-v <name> View script with the given name. The script if retrieved sucessfully is output to standard output. -l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active script. -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services. -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since sieve names may not contain a '.'. -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option.. -d <name> Delete the sieve script on the server with <name>. -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen. -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is overwritten. -u <user> Userid/Authname to use for authentication; by default, the current user. CMU
