Or anything else, for that matter.

I know that. Actually, there is one other type - absolute - but that doesn't apply here. > The aim is NOT to calculate any rate over an unknown time, rather the > aim of this fictitious example is to calculate % network utilization > since the time the value was last acquired. Can you suggest an MRTG > expression and type to do it? Set it to guage and let rrdtool deal with it as a stacked area with average calcs. It's always best to store raw data and derive displayed data. The underlying data is a counter that rolls over rather quickly - let mrtg deal with the roll-over counter, providing you with rates, and let rrdtool provide the averages. -- Daniel J McDonald, CCIE # 2495, CNX, CISSP # 78281 Austin Energy [EMAIL PROTECTED] -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
