Hi,
I am having trouble walking a table of a mib I have created. It only prints the first column of each table row.
I created a mib and ran the mib2c program to create a skeleton source code, then went in and added code were the XXXs are and following the examples in the net-snmp-5.1.1 source tree.
Maybe I do not understand the three functions called:
<tablename>_get_first_data_point() - Point to first structure in linked list, the stucture contains all the information for a single row in the table.
<tablename>_get_next_data_point() - Move point to next row in linked list.
<tablename>_handler() - Loop through the row returning the value for each column in a single table row.
When I use the DEBUGMSGTL macro and place an output trace message in each function I will see the following pattern in the snmpd.log file.
<tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1. <tablename>_get_first_data_point here 1.
<tablename>_get_next_data_point here 2.
<tablename>_handler here 3.
The table has only 1 index and it is of type INTEGER and the total number of columns in the table is 9. (min_column = 2, max_colum = 9)
The 'requests' loop in the <tablename>_handler function will only loop once.
If the <tablename>_get_first_data_point is used to set the starting point of the table rows then why is it called once for each column in the table minus the index count?
Who sets up the requests link list that is passed to the <tablename>_handler function?
The scalar objects in my mib work fine. Been working on the table part of this for a week now and I am getting no were.
As a note, the examples on the web site need to be expanded. Use mibs with more than one table and several columns per table. I for one learn best with examples and documentation pointing out the finer points of the code.
Thanks in advance for any help you can give.
