Does anyone know of a bandwidth monitoring program I could put on my linux server to see what individual files are using the most bandwidth?

Thanks!

I think monitor with file statistik doesn't exist. It may be monitor with port and direction statistic. But it do not know what file downloaded beckouse it's hight level package.

If you want what individual files are using the most bandwidth. Try use site log analyser . Or just see size for site access.log file. Ussually it's help.
