Hello all, I'm currently running a project in my school, which need to provide datas over SNMP.
Here is a small overview of the context : We have small temperature sensors (embedded devices) that will periodically send information through the network to a central server. (those devices can't run their own snmp agent). The application on the server will store the data in a linked list. The same program is a subagent aswell, and will feed the data into the snmp agent of the server. Those datas may change quite fast (every 15s for example). So, here are some questions i'm asking myself : 1. I've choosed the Iterator solution, as explained when running mib2c (the data are held outside from the agent itself). Is that the right choice ? 2. With the iterator system, i don't really understand how the whole is working. when a SNMP GET request comes, does it walk through the linked list to find the index ? Or does the agent held a cached version of my datas by his side ?. 3. I don't really get the difference between my_loop_context and my_data_context pointers. Same goes for the _get_first_data_point and _get_next_data_point functions. 4. When the program is started, there's no available datas. this mean i my linked list is empty. will net-snmp understand that there's no entry ? There's quite a lot of points that aren't realy clear to me at the moment. I hope your answer will allow me to go ahead with my project. Thanks in advance for your answers.
