I am currently collocating 4 Win2K web servers and for the last month, I have been getting bandwith spikes usage which have pretty much double my hosting bill. These spikes occur every hour or so and go up to 5mb/s per the MRTG graph the data center provides. This is data that is coming from the server and not into it. Since MRTG does not break it down the usage by IP, I am having a hard time finding out which server is the one that is generating the traffic. What can I do get to get to the bottom of this issue?
Any suggestions will be greatly appreciated.
