I'm having trouble getting correct results from SNMP queries sending back Gauge32 values. With snmpwalk I get the following:

snmpwalk -v2c -c public nasusb1 .1.3.6.1.2.1.25.1.6 
HOST-RESOURCES-MIB::hrSystemProcesses.0 = Gauge32: 77


So, the number of processes on nasusb1 is 77. However, Argus graph shows this value as 0. Debugging shows:

srvc::result_valid	1
srvc::retries	2
srvc::showreason	0
srvc::showresult	0
srvc::starts	16
srvc::state	done
srvc::status	up


My config is:

Service UDP/SNMP {
community:	public
debug:	yes
drawgrid:	yes
graph:	yes
label:	processes
maxvalue:	200
oid:	.1.3.6.1.2.1.25.1.6
}


Debug log shows:

Sep 14 10:23:59 admin Argus[8141]: DEBUG - Top:Servers:nasusb1:cpu:SNMP_.1.3.6.1.2.1.25.1.6_nasusb1 - [] Service done 

So, it appears that Argus simply fails to process correctly SMNP response, since "result found" is blank instead of 77.

Any suggestions?

snmpwalk started at the oid you gave on the command line,
and returned data for all of the oids that follow it.

oid ".1.3.6.1.2.1.25.1.6.0" has a value of 77
oid ".1.3.6.1.2.1.25.1.6"   does not have a value, and is not  
displayed by snmpwalk.
