Hi,
I'm having the same problem when registring to the sysORTable from the
example demon from the subagent tutorial.
http://www.net-snmp.org/tutorial/tutorial-5/toolkit/demon/index.html
Should I use register_sysORTable() in the subagent to register to the
masters sysORTable or should I use some other function to trigger the
callback functionality?
This is what i've added to the init_nstAgentSubagentObject() function:
void
init_nstAgentSubagentObject(void)
{
static oid nstAgentSubagentObject_oid[] =
{ 1, 3, 6, 1, 4, 1, 8072, 2, 4, 1, 1, 2, 0 };
/*
* a debugging statement. Run the agent with -DnstAgentSubagentObject
to see
* the output of this debugging statement.
*/
DEBUGMSGTL(("nstAgentSubagentObject",
"Initializing the nstAgentSubagentObject module\n"));
/*
* the line below registers our variables defined above as
* accessible and makes it writable. A read only version of any
* of these registration would merely call
* register_read_only_int_instance() instead. The functions
* called below should be consistent with your MIB, however.
*
* If we wanted a callback when the value was retrieved or set
* (even though the details of doing this are handled for you),
* you could change the NULL pointer below to a valid handler
* function.
*/
DEBUGMSGTL(("nstAgentSubagentObject",
"Initalizing nstAgentSubagentObject scalar integer. Default
value = %d\n",
nstAgentSubagentObject));
netsnmp_register_int_instance("nstAgentSubagentObject",
nstAgentSubagentObject_oid,
OID_LENGTH(nstAgentSubagentObject_oid),
&nstAgentSubagentObject, NULL);
DEBUGMSGTL(("nstAgentSubagentObject",
"Done initalizing nstAgentSubagentObject module\n"));
/* register compliance in sysORTable */
{
register_sysORTable(nstAgentSubagentObject_oid,
OID_LENGTH(nstAgentSubagentObject_oid),
"nstAgentSubagentObject");
}
}
