Yes, you have to tune your rrdfile. Once it is created, just do: rrdtool tune -i DS0:-5 -i DS1:-5 /path/to/the/rrdfile.rrd That will lower the minimum from 0 to -5. I really should hack up that chunk of code to deal with minimums so that it will create the rrd's correctly the first time. It's not hard, and it would be a help when I monitor RSSI on various wireless devices. -- 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
