Good Day to all the memebers in this list. Actually I am stuck in a problem and I need your help desperately. I intend to generate mails to the administrator whenever any of the interface goes down in a router.I have been using MRTG successfully to configure my router and plot graphs for its usage. For generating the graphs I have read about threshold vaues, but these values are for input and output rate, and then calls the external program to use SMTP to send mails.But it doesnt respond to tell if the interface is now down and then generate mails. Can anyone help me to suggest how can I make my program call the other module on this condition(how to trap this event, basically) and generate mails. Thanks & Regards Himanshu Madan. -- Unsubscribe mailto:mrtg-request@list.ee.ethz.ch?subject=unsubscribe Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
