Reading Data From the demo_module_4.conf Configuration File

Data is read from the configuration files into a module by registering a callback function to be called whenever an appropriate token is encountered. For example, you can call the function as follows:

register_config_handler(demo_module_4, threshold_loadavg1, 
read_load_thresholds, NULL, NULL);

Whenever a threshold_loadavg1 token in the demo_module_4 file is read by the agent, the function read_load_thresholds() is called with token name and value as arguments. The read_load_thresholds() function stores the token value in appropriate variables:

void
read_load_thresholds(const char *token, char *cptr)
{

    if (strcmp(token, "threshold_loadavg1") == 0) {
        threshold_loadavg1=atof(cptr);
    } else if (strcmp(token,"threshold_loadavg5") == 0) {
        threshold_loadavg5=atof(cptr);
    } else if (strcmp(token,"threshold_loadavg15") == 0) {
        threshold_loadavg15=atof(cptr);
    } else {
        /* Do nothing */
    }

        return;

}
