I use RedHat9 as a small office network server. I use squid as proxy. I want to know how many MBs are used hourly, daily. Actually, I want to measuring internet tarfic.
What is the easiest way to do this?
Are there any applications in RedHat9 which do this?

Thank you!

You can use MRTG. It'll provide you html pages updated every 5 min with 4 graphs (daily, weekly, monthly yearly) There are many add-on to tinker this to fit your need:

Hope this help

Depending on the kernel you're running, you could try playing around with either ipac (2.2 / ipchains) or ipac-ng (2.4/2.6 iptables).

They basically provide easy configuration of your ipchains/iptables accounting policies, and it runs from your crontab so you can set the summary resolution down to a few minutes if you want. There are a few auxilliary programs that come with it, like ipacsum, which will give you summaries between different times etc. It's pretty nice; one of my favourites.

If you just want squid proxy reporting, Calamaris is worth looking at.

also. have a look a bmon. Easy to use, provides nice and pretty realtime ASCII graphs.
