Update:
Checked the value returned from netsnmp_register_scalar_group
The first scalar group I tried to register got value 0(MIB_REGISTERED_OK).
All the others got value -1(MIB_REGISTRATION_FAILED or
MIB_DUPLICATE_REGISTRATION).
I have checked all scalars that was registered and there was no duplicate on
either name or oid.
So what could the cause be for this failure to register my scalars?
Anyway, trying to snmpget the one scalar that got OK still returned "No Such
Object available on this agent at this OID".
I even tried registering all scalars one by one, instead of in groups.

Emne: Debugging SNMP
Hello, me again. Have been sending a few messages lately. Hope I am not nagging
to much.
Is there a way I could debug snmp. I have gotten my C++ program to work as an
SNMP AgentX. I have managed to register 3 hard coded test scalars and it works
when I snmpget on those scalars.
Thus removing these hard coded scalars I then try to add my own scalars.
const char *buffy = group_name.c_str();
netsnmp_register_scalar_group(
netsnmp_create_handler_registration(buffy,
handle_snmp,
group_oid,
OID_LENGTH(group_oid),
HANDLER_CAN_RONLY
), 1, scalars_total); //up to the max number of scalars in this group
When I try to snmpget on scalars I just get:
SNMPv2-SMI::enterprises.40463.2.1.0 = No Such Object available on this agent at
this OID
I know I have a scalar group of OID 1.3.6.1.4.1.40463.2 which have 8 scalars.
After I have registered all my scalars is there a way to check if there really
is any scalars registered and which ones?
Content of net-snmp.log. This is actually alot for only one snmpget. The last 3
lines continues every few seconds.
