When you mean nested, you actually mean a table with indexes that
reference indexes from the first table right?
Thanks Wes. That's right . I have got it now and able to progress . I was
confused whether to make tree structure .
This is basically making the tree to linear array by storing the indexes of
each parent/grand parent node. right ?
Another issue I am finding that OID's are getting registerd two times(might
be).
snmpwalk is showing duplicate data . I could not figure out . what could be
the
issue ?
I have added all the columns.
netsnmp_table_helper_add_indexes(table_info,
ASN_INTEGER, /* index: messageIndex */
ASN_INTEGER, /* index: msgVMIndex */
ASN_OCTET_STR, /*vmName*/
ASN_INTEGER, /* vmId */
0);
If I do not add all the columns, it is crashing. is it mandatory to add all the
columns ?
You need to understand a bit more about SNMP to properly implement
that. You can still do it with the iterator code, but you need to
handle returning the multiple indexes from the lookup functions (_first
and _next). The data function will still need to retrieve the right
data given the indexes found.
