All, I'm looking into something that monitors incoming and outgoing bandwidth on a Linux machine; ideally something that outputs the average values per minute (or even second) to a log file that I can then scrutinize. The machine runs SLES11 and runs several daemons (httpd, smtpd, sshd) while also working as a router for a LAN with about a dozen machines behind it. I think I need a faster connection to the internet but I want to be 100% sure that a) this is the case and b) it isn't just a matter of one process/machine taking up most of the bandwidth. /sbin/ifconfig gives the number of RX and TX packets as well as bytes, so I can write a script that just check it every x seconds and subtracts the previous value, but I'm not 100% sure if these are really the numbers I'm looking for. Thanks. Martijn. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
