Hi,
Recently I have coded my own MIB module based on a stub file that was
originally auto-generated by mib2c using mib2c.iterate.conf. The version is
5.2.2. The module contains a table with 10 columns and currently 125 rows.
Since I want to get the newest data from system when a GETBULK message come
in. I have an init_table() function in get_first_data_point(). The
init_table() function get the data from system by TCP and set them to a
given dataset. Then get_next_data_point() can get data from the dataset and
return to manager.
The table seems to be working well but I was quite surprised to see that the
functions get_first_data_point() get called 20 times if I get the table
using GETBULK messages while the Max-Repetitions is set to 20. So the
init_table() has to be executed 20 times. It takes too much time.
I have read some others questions similar with mine. The answer is change to
netsnmp_inject_handler instead of mib2c.iterate.conf. Is there anyone can
show me a way not to change the helper but modify my code to decrease the
execute init_table() times?
Sincerely
Peter
