[mrtg] noSuchName?

[Phil Iovino]

I'm trying to get the "User vs Idle CPU usage" working per
http://www.net-snmp.org/tutorial-5/mrtg/index.html. Here is the block in
my mrtg.cfg -

LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
Target[ns2-cpu]:ssCpuRawUser.0&ssCpuRawIdle.0:xxx at ns2.nxtek.net
MaxBytes[ns2-cpu]: 100
Title[ns2-cpu]: CPU LOAD
PageTop[ns2-cpu]: <H1>User CPU Load %</H1>
Unscaled[ns2-cpu]: ymwd
ShortLegend[ns2-cpu]: %
YLegend[ns2-cpu]: CPU Utilization
Legend1[ns2-cpu]: User CPU in % (Load)
Legend2[ns2-cpu]: Idle CPU in % (Load)
Legend3[ns2-cpu]:
Legend4[ns2-cpu]:
LegendI[ns2-cpu]:  User
LegendO[ns2-cpu]:  Idle
Options[ns2-cpu]: growright,nopercent

Note that my path to UCD-SNMP-MIB.txt is correct. I do see mention of
ssCpuRawUser and ssCpuRawIdle in /usr/share/snmp/mibs/UCD-SNMP-MIB.txt.
When I run it, I get this -

SNMP Error:

Does anyone have any ideas?
