Looking at the "rate" line I thought to myself..."cool I can use this to graph throughput avg.es without having to worry about the "Sent bytes" rolling over or being lost when the htb qdisc is recreated" _BUT_ it seems the rates are inaccurate. When I look at the rate my cisco router reports for a 5min avg and I look at a calculated 5min average (30 polls of the tc once every 10sec) for tc they are very different. The cisco is reported as ~2090kb/s and tc reports my parent as ~251kb/s. Even if I take all the classes separately and add the averages together I get closer but not that much closer. Is my math wrong? How does the tc/htb qdisc figure the avg. rate? -- David DeLauro Talk sense to a fool and he calls you foolish. - Euripides Those who do not think about their own sins make up for it by thinking incessantly about the sins of others. - C.
