Dear all,
I figured out some bugs in my code .. so please ignore the earlier
mail and consider this code
void
init_DryContactTable(void)
{
netsnmp_table_data_set *table_set;
netsnmp_table_row *row;
/*
* the OID we want to register our integer at. This should be the
* * OID node for the entire table. In our case this is the
* * netSnmpIETFWGTable oid definition
*/
init_values();
oid my_registration_oid[] =
{ 1, 3, 6, 1, 4, 1,4325,2,1};
//1.3.6.1.2.1.2.3
DEBUGMSGTL(("DryContactTable",
"Initalizing example dryContact table\n"));
table_set = netsnmp_create_table_data_set("DryContactTable");
/*
* allow the creation of new rows via SNMP SETs
*/
table_set->allow_creation = 1;
/*
* set up what a row "should" look like, starting with the index
*/
netsnmp_table_dataset_add_index(table_set, ASN_INTEGER);
/*
* define what the columns should look like. both are octet strings here
*/
netsnmp_table_set_multi_add_default_row(table_set,
//DryContact PortID
2, ASN_INTEGER, 1, NULL, 0,
// DryContactPortType
3, ASN_INTEGER, 1, NULL, 0,
//DryContactDisplay String
4,ASN_OCTET_STR,1,NULL,0,
// DryContactPortValue
5,ASN_INTEGER,1,NULL,0,
0 /* done */ );
/*
* register the table
*/
/*
* if we wanted to handle specific data in a specific way, or note
* * when requests came in we could change the NULL below to a valid
* * handler method in which we could over ride the default
* * behaviour of the table_dataset helper
*/
int ret;
ret=netsnmp_register_table_data_set(netsnmp_create_handler_registration
("DryContactTable", NULL,
my_registration_oid,
OID_LENGTH(my_registration_oid),
HANDLER_CAN_RWRITE), table_set, NULL);
if(ret==0)
{
DEBUGMSGTL(("DryContactTable",
"REGISTRATION SUCCESSS!!!!~####### \n"));
}
else
DEBUGMSGTL(("DryContactTable",
"REGISTRATION FAILED @@@@@@@@@@@@@@@@@@@@@@@ \n"));
DEBUGMSGTL(("DryContactTable",
"Table registered with the OID which comes under interfaces \n"));
int i=1;
for(i=1;i<=10;i++)
{
/*
* create the a row for the table, and add the data
*/
row = netsnmp_create_table_data_row();
/*
* set the index to the IETF WG name "snmpv3"
*/
netsnmp_table_row_add_index(row, ASN_INTEGER,
(char*)&DryContacts_Details[i].dryContact_PortID,
sizeof(DryContacts_Details[i].dryContact_PortID));
/*
* set column 2 to be the WG chair name "Russ Mundy"
*/
ret= netsnmp_set_row_column(row, 2, ASN_INTEGER,
&DryContacts_Details[i].dryContact_PortID,
sizeof(DryContacts_Details[i].dryContact_PortID));
netsnmp_mark_row_column_writable(row, 2, 1);
ret= netsnmp_set_row_column(row, 3, ASN_INTEGER, (char*)
&DryContacts_Details[i].dryContact_PortType,
sizeof(DryContacts_Details[i].dryContact_PortType));
netsnmp_mark_row_column_writable(row,3, 1); /* make writable
via SETs */
if(ret==0)
{
DEBUGMSGTL(("DryContactTable",
"Added a element !!!!~####### \n"));
}
else
DEBUGMSGTL(("DryContactTable",
"Addition FAILED @@@@@@@@@@@@@@@@@@@@@@@ \n"));
ret=netsnmp_set_row_column(row,4, ASN_OCTET_STR,
&DryContacts_Details[i].drycontact_DisplayString,
strlen(DryContacts_Details[i].drycontact_DisplayString));
if(ret==0)
{
DEBUGMSGTL(("DryContactTable",
"Added a element !!!!~####### \n"));
}
else
DEBUGMSGTL(("DryContactTable",
"Addition FAILED @@@@@@@@@@@@@@@@@@@@@@@ \n"));
netsnmp_set_row_column(row, 5, ASN_INTEGER, (char*)
&DryContacts_Details[i].dryContact_PortValue,
sizeof(DryContacts_Details[i].dryContact_PortValue));
}
//netsnmp_register_auto_data_table(table_set, NULL);
DEBUGMSGTL(("example_data_set", "Done initializing.\n"));
/*
* Finally, this actually allows the "add_row" token it the
* * snmpd.conf file to add rows to this table.
* * Example snmpd.conf line:
* * add_row netSnmpIETFWGTable eos "Glenn Waters" "Dale Francisco"
*/
}
This is the initializations piece of code ; But still I am not able to
access this table elements through snmpget. Can anyone shed light on
the mistake I am making .
Thanks in advance.
