That is doing it the hard way. Use scripts only if there isn't an OID 
for what you want.

Target[hostname_load]: laLoadInt.2&laLoadInt.2:community at host:::::2
RouterUptime[hostname_load]: community at host:::::2
MaxBytes[hostname_load]: 30000
Title[hostname_load]: System Load
Factor[hostname_load]: 0.01
YTicsFactor[hostname_load]: 0.01
YLegend[hostname_load]: System Load
Legend1[hostname_load]: Load
Legend2[hostname_load]:
Legend3[hostname_load]:
Legend4[hostname_load]:
LegendI[hostname_load]: Load
LegendO[hostname_load]:
ShortLegend[hostname_load]: load
Options[hostname_load]: gauge,growright,nopercent
Directory[hostname_load]: hostname

Make sure you load the correct MIB otherwise you might have to use the 
OID instead of the symbolic name.

LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
