Scouring the web and the mailing list archive for information about implementing a callback logging. I could only find bits and pieces.
If I haven't overlooked it and it is actually there, I think this information should be available on the Net-SNMP Wiki. A small tutorial on how to implement callback logging with your own or your favorite logging framework.
I am though left with a few remaining questions:
What should I do with majorID and minorID in the callback function (in this case defined in snmp_register_callback)? Is there some situation where one would need to check the majorID and minorID in the callback?
What do I return in my callback function?
log4cplus:: Logger snmp_logger = log4cplus:: Logger::getInstance(LOG4CPLUS_TEXT("SNMP"));
extern "C" {
SNMPCallback logging_callback;
}
int main(int argc, char **argv) {
snmp_enable_calllog();
snmp_register_callback(SNMP_CALLBACK_LIBRARY, SNMP_CALLBACK_LOGGING, logging_callback, NULL);
}
int
logging_callback(int majorID, int minorID, void *serverarg, void *clientarg) {
snmp_log_message *log_message = (snmp_log_message *) serverarg;
string message = log_message->msg;
LOG4CPLUS_INFO(snmp_logger, LOG4CPLUS_TEXT(message));
return 1;
}
