Network Monitoring Specific
Intelligent Network Monitoring

The Network Monitoring Specific API provides functions for provide monitoring specific.

Required Header

#include <inm.h>

Overview

This set of functions is used to get information about network information provided by well-known linux functions. To use This kind of APIs, You should create a inm handle using inm_initialize(). After that, you can obtain network information. You should destroy the created inm handle if you do not need it anymore. You can detect IP collision, do dump network status, dump TCP, monitor ethernet, Wi-Fi module state, get network statistics.

Related Features

This API is related with the following features:
