Just joined the list 30 seconds ago. :) I'm working with net-snmp and agentx. I have to register my enterprise OIDs for scalars and tables. For example:
> netsnmp_register_read_only_scalar(...); // register my scalars
> netsnmp_tdata_register(...); // register my table
Until I make those calls in my agentx code, my OIDs don't show up in snmpd.
My MIB file also has NOTIFICATION-TYPE definitions, such as:
> myTrapTest NOTIFICATION-TYPE
> STATUS current
> DESCRIPTION "A sample trap."

I took a look at #include <net-snmp/agent/agent_trap.h> but this file seems to be about sending traps, not registering custom ones.
My question: What do I call to register my trap definitions?
