-Alex- Posted September 24, 2008 Share Posted September 24, 2008 Hey all, After much Googling, I can't seem to find a command that just tells me how much traffic has passed through eth0, surely there must be one? All I need is a command I can run which outputs something like "Down: 100GB - Up: 600GB". Any suggestions? I've got root access to the box and it's running CentOS 5.2 in a remote datacenter. Cheers!

zeroday Posted September 25, 2008 Share Posted September 25, 2008 Maybe your main network is something else? Try just plain 'ifconfig' and see if any of the interfaces match your b/w usage. That or leaseweb measured it wrong. Btw, direct ssh root login and running sshd on default port is a bad idea security-wise. Link to comment Share on other sites More sharing options...

markwolfe Veteran Posted September 25, 2008 Veteran Share Posted September 25, 2008 If you aren't a fan of just using the count in ifconfig, maybe a more advanced tool would suit your needs a bit more? http://www.ubuntugeek.com/bandwidth-monito...-for-linux.html That link lists several, though I have never used any of them. Might I point out that if you are interested in your network bandwidth to your ISP, then monitoring at your router would be the correct option, especially if you have multiple devices on your home network.

Unfortunately in this case and many others this is a server in a DC. Link to comment Share on other sites More sharing options...
pyther Posted September 26, 2008 Share Posted September 26, 2008 Look at a program called vnstat this should do exactly what you want (command line util) Link to comment Share on other sites More sharing options...

The box is in a datacenter. Look at a program called vnstat this should do exactly what you want (command line util) I installed this about a week ago.

pyther Posted September 27, 2008 Share Posted September 27, 2008 The INSTALL file for vnstat, suggest running the update every 5 minutes via cron. However running it every 5 minutes, will put next to no load on the server. Link to comment Share on other sites More sharing options...
