I am setting up our MRTG configs to use the Threshold feature, and send out an automated email when traffic reaches 0%. I understand how to make the additions to my configs, but I am at a loss how to write a script that can be called by MRTG which will send the email when the threshold is reached. I am using RedHat 7.1 and Sendmail 8.11 Can anyone help me with this? Raymond
