<div dir="ltr"><font face="Tahoma" size="2"><span style="FONT-SIZE: 12pt">As people have mentioned, the Thresholding is defined per-target, although some settings are global (email servers, addersses, cache dir).</span></font></div>
<div dir="ltr"><font face="tahoma" size="2"><span style="FONT-SIZE: 12pt">What you want (only notify if over the threshold for a certain length of time) is a bit too sophisticated for MRTG's simple notification system; I'd suggest you look at something like
Nagios and configure MRTG thresholding to send an alert into Nagios for it to handle (what we do). This would require a very simple alert script so send a Nagios NSCA message.
</span></font></div>
<div dir="ltr"><font face="tahoma" size="2"><span style="FONT-SIZE: 12pt">If you only have a couple of things then Nagios might be overkill though, although I have a fondness for the Nagios/MRTG combination as they interface nicely in the web pages and can
share the same monitoring agents.</span></font></div>
