Well, I'm sure there's a better way, but I just use something like netstat -I fxp0 -w 300 > file_199909161855_start & varying the interval as desired - which is fine if you are satisfied with data on the aggregate in and out traffic for a particular interface. I name the file according to the start time, so it's easy to figure the actual time of any given entry. (The timing does tend to slip a few seconds a day on my server with -w 300, more with shorter intervals.) Resource usage seems minimal, even running with a 1 second logging interval. With a little manipulation with Unix utilities, or with a spreadsheet, I can generate some pretty useful statistics and graphs. -- Graeme Tait - Echidna To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
