Bandwidth Monitoring

[annasad]

hi i have set up the Cacti on my Linux box of CentOS .
and its working fine .Thold has also been set up onto different features of it .now i have one thing left behind which i am not able to find out an answer

here is a detail

i have set up thold on the bandwaidth utilization of Let say 80 % .now what happen is that even if it touche the 80 % for one sec . it generates a Alert E-mail and now what happen is that it touches the limit more than 50 times a day and every time an E-mail as a alert is triggered . and i have junks of e-mail in my support inbox .

My question is that is there any way out that i can make a THOLD in a way that when a traffic conitinues 5 mins at 80 % then it should trigger an E-mail or if it cross more than 20 times above 80 % in a day ONLY THEN IT SHOULD TRIGGER an alert rather than sending an alert every time .
