I have checked and there is only once instance of my subagent running. It is
running as a separate process using AgentX protocol.
I have tried to manually register 3 hard coded scalars, one by one, each with
its own handler:
int returnValue1 = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration("test1",
handle_snmp,
test1_oid,
OID_LENGTH(test1_oid),
HANDLER_CAN_RONLY
));
int returnValue2 = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration("test2",
handle_snmp,
test2_oid,
OID_LENGTH(test2_oid),
HANDLER_CAN_RONLY
));
etc...
This works fine and snmpget returns a value. However , if I put these 3 hard
coded scalars OID in a list, iterate over that list and register them, I get a
duplicate error.
for (oid_iterator) { //Overlook pseudocode here
const oid *oid_value = (*oid_iterator);
const char *buffy = tmp_string.c_str();
int returnValue = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration(buffy,
handle_snmp,
oid_value,
OID_LENGTH(oid_value),
HANDLER_CAN_RONLY
));
}

Emne: RE: Debugging SNMP
I don’t know in your case, but one reason is because of execution of a subagent
code multiple times. So when you run your subagent with “./XXX &” make sure
that the previous execution has already been stopped. And if you have compiled
the code with master agent, In that case you have to replace your “
libnetsnmpmibs.so.X... “ files... and then you have to execute it as subagent.

I have checked the contents of each elements inputted into
int returnValue = netsnmp_register_read_only_scalar(
netsnmp_create_handler_registration(buffy,
handle_snmp,
scalar_oid,
OID_LENGTH(scalar_oid),
HANDLER_CAN_RONLY
));
For each iteration of the loop the OID and scalar name is unique. So why does
it returns MIB_DUPLICATE_REGISTRATION?

Try printing out the value of 'scalar_oid' (and 'scalar_length')
each time round the loop.
What is the registration call *actually* being invoked with?
(as opposed to what you think it _should_ be invoked with)
