Re: Debugging SNMP
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.

For each iteration of the loop the OID and scalar name is unique. So why does
it returns MIB_DUPLICATE_REGISTRATION?

Re: Debugging SNMP
Thats correct, its the netsnmp_register_scalar which returns -1. Function netsnmp_create_handler_registration returns a pointer to an netsnmp_handler_registration. I have also tried to output the handler memory address, and its not always unique. Don't know if it has anything to do with the problem. My hypothesis is that perhaps it doesn't create an unique handler for each scalar. Could I create an netsnmp_handler_registration without the helper-function netsnmp_create_handler_registration? Perhaps that would solve the problem. Packaged dump output.

Re: Debugging SNMP
I'm not sure if I found a solution to my problem, but anyway
netsnmp_handler_registration *handler_reg =
netsnmp_create_handler_registration(buffy,
handle_snmp,
scalar_oid,
OID_LENGTH(scalar_oid),
HANDLER_CAN_RONLY);
I tried to output each handler, and rootoid_len that comes from
OID_LENGTH(scalar_oid) was 1 for all scalars. I reckon this value should be the
length of the OID (1.3.6.1.4.1.40463.2.1 = 9).
I have my own wrapper class around an OID with the length, when I used this
length instead of OID_LENGTH(scalar_oid), it registered all my scalars with no
duplicates.
Why does this work for my 3 hard coded scalars, but not my list of scalars?
const oid scalar_oid[] = { 1,3,6,1,4,1,45678,1,1 };
OID_LENGTH(scalar_oid) gives value 9.
const oid *scalar_oid = wrapper.getOid(); //Has same oid within. Returns a
pointer to an oid.
OID_LENGTH(scalar_oid) gives value 1.
Both of these is just a pointer right? So why does OID_LENGTH work one the
first, but not the second?
My immediate problem is solved. Thanks for all assistance.

No.
The first case is an array,
so sizeof(scalar_oid) gives 36 (assuming a 32-bit system),
and hence OID_LENGTH gives 9
(sizeof(scalar_oid)/sizeof(oid))
The second case is a pointer,
so sizeof(scalar_oid) gives 4 (again, assuming a 32-bit system)
and hence OID_LENGTH gives 1
(sizeof(scalar_oid)/sizeof(oid))
Glad you got things sorted.

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.

Re: Debugging SNMP
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. /Sverre - Original Message - Fra: Sverre Moe sve...@spacetec.no Til: net-snmp-users net-snmp-users@lists.sourceforge.net Sendt: 26. oktober 2012 10:19:24 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.

All the others got value -1(MIB_REGISTRATION_FAILED or MIB_DUPLICATE_REGISTRATION). Do the other groups use the same root OID as the first registration, or do they all use different roots? The usual cause of a duplicate registration would be having two invocations of netsnmp_register_xxx() with the same root OID (i.e. the third/fourth parameters to the netsnmp_create_handler_registration call) If that's not the case, it's probably worth posting the full code of the block used to register these groups.

Re: Debugging SNMP
I have tried to output the scalar name, oid and oid length. On every iteration it prints out a new unique scalar. Many scalars, but here is the output of a few: Scalar: version 1.3.6.1.4.1.40463.2.1 Scalar: primary 1.3.6.1.4.1.40463.2.2 Scalar: available 1.3.6.1.4.1.40463.2.3 Scalar: hostname 1.3.6.1.4.1.40463.2.4 And none of these occur more than once. Don't understand you last question. /Sverre - Original Message - Fra: Dave Shield d.t.shi...@liverpool.ac.uk Til: Sverre Moe sve...@spacetec.no Kopi: net-snmp-users net-snmp-users@lists.sourceforge.net Sendt: 26. oktober 2012 14:52:18 Emne: Re: Debugging SNMP On 26 October 2012 13:29, Sverre Moe sve...@spacetec.no wrote: Full code of my scalar registration.
