Bandwidth Meter for Microsoft Virtual Server 2005 is a unique tool for MS Virtual Server 2005 bandwidth usage monitoring, counting and reporting.
What makes it unique? It provides a bandwidth control on per virtual server basis for different protocols (ARP, TCP, UDP, ICMP, IGMP). With this tool you can see the amount of data used (downloaded and uploaded) by each virtual server. Thus you can bill your customers for the bandwidth usage or just find out which servers cause a high network load.
Installation is straightforward and only takes a minute by entering IP address of your server and clicking several buttons.
