MRTG polls for octets sent and received. 1 octet = 1 byte = 8 bits. The percentage calculated by MRTG is based on the MaxBytes value in your cfg file. To get the right percentage the Maxbytes value should be set to the maximum number of octets that can be sent or received on a specific port. If you know the maximum bit rate of a port devide by 8 and you get the right value for Maxbytes. Usually cfgmaker will take care of this.

Maybe I am thinking of this the wrong way but I have setup some unscaled graphs in MRTG using: MaxBytes:1000000000 So that I can get a picture of how much of the pipe we are filling up on our 100mega bit switch. I get a good graph, showing that I am filling about half, 53.2Mb/s but then the percentage behind the Max is (6.7%) Where is that number coming from? Shouldn't it be 53%? Is there some additional setting I need to change or am I just not reading it right? --ja -- -- 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 _________________________________________________________ Het ministerie van Sociale Zaken en Werkgelegenheid sluit elke aansprakelijkheid uit in verband met het niet juist, onvolledig of niet tijdig overkomen van de informatie in deze e-mail.
