Perhaps you should share this "something" with us... The way MRTG should work: 5-minute average #1 \ 5-minute average #2 \ 5-minute average #3 \ 30-minute average = (#1+#2+#3+#4+#5+#6)/6 5-minute average #4 / 30-minute maximum = max(#1,#2,#3,#4,#5,#6) 5-minute average #5 / 5-minute average #6 / 5-minute average #1 \ 5-minute average #2 \ 5-minute average #3 \ 30-minute average = (#1+#2+#3+#4+#5+#6)/6 5-minute average #4 / 30-minute maximum = max(#1,#2,#3,#4,#5,#6) 5-minute average #5 / 5-minute average #6 / and so on; dito for 30-minutes --> 2 hour and so on. -- Much of what looks like rudeness in hacker circles is not intended to give offence. Rather, it's the product of the direct, cut-through-the-bullshit communications style that is natural to people who are more concerned about solving problems than making others feel warm and fuzzy. http://www.tuxedo.org/~esr/faqs/smart-questions.html -- Unsubscribe mailto:[EMAIL PROTECTED] 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
