I've been doing a lot of searching around for a tool to monitor a website's "bandwidth" usage, and I'm not talking about how many MB/data is being loaded but the servers actual output speed, to clarify what I mean I'll use an' example,
My server has a Internet connection at 100/MBs, I want to be able to monitor how much of that 100/MBs is being used, and have it being logged, (As a background process).
I've tried different kind of tools such as Zabbix, Nagios and ntopng(ntop), all useful tools but none of them seem cable of logging the actual server speed / usage of the speed. Currently I still have Ntop(ng) installed but I am unable to get it to do what I want it to. (it is vital that the data is logged 24/7)
The reason for this is that due to me hosting files that people can download I am with the low internet connection sometimes hitting that cap, and I want to be able to monitor when / how offen I hit that cap.
My server is a Ubuntu 12.04 running with Apache 2.2, I don't know whether it's needed but in case: My domains are setup with Virtual hosts for each domain.
I appreciate any help and hints I can get.
