: Is 322 gigabytes traffic for Partial contents normal? We have a small community for our university students. There we provide some tutorials and other stuff that may help students to accomplish

We have a small community for our university students. There we provide some tutorials and other stuff that may help students to accomplish their task better.

The catch is I think our traffic is abnormally high! We only have 2000 visits per day at its best (for the last 3 month we have had something around 1500 visits per day - more info here). Having this said, our monthly traffic has been ranging from 30 Gigabytes for our first month to 70 Gigabytes for the last month and now 322 Gigabytes for the past 16 days of the new month!

I checked the awstats figures and found that 98% of this traffic is for partial contents .
Now my question are:


Having said all this about our community and its size, is this
abnormal?
How can we get more information on the contents being downloaded on our community site?
In case it is abnormal and abusive how can we avoid it?

We see a lot of requests for "Partial Content" when the document served is PDF. If your PDF documents are optimized and the server and client both support it (mostly likely they do) then all .PDF files will be served as 'byte-range' requests. So even if the entire PDF is downloaded the request will appear as a series of requests for partial content.

My experience is with Apache but I expect IIS is similar.

I think it is extremely unlikely to be abuse.

If you need more details on downloads and you might be able to tweak awstats settings to give more detail than you are seeing by default. Alternatively you could look at analog which is very very configurable and use it forensically to dig into this issue.
analog.cx
But really, I don't think anything is out of the ordinary here.

If we'll divide the 322GB on 16 days and 2000 visits we'll get about 10MB per visit. It may be absolutely normal if you have on the site some video or pdf files.

Google Analytics can help tracking the traffic.
