Hi experts!

I have a couple of hosts in a data center and I have a full 10mb link that is having a 12mb average use, but I can't find which virtual machine is causing that.

Can you help me figure it out? I need some tool to monitor this virtual machines and find the solution for this problem.

My hosts are Windows Server 2012 and my virtual machines are a mix of Servers 2008R2 and 2012.

Thank you.

Note the last bullet under Measuring Network Performance:
"Measure network utilization on the guest operating systems – If a network adapter on the Hyper-V root partition is busy as indicated by the performance monitor counters mentioned above, then consider using the "\Hyper-V Virtual Network Adapter(*)\Bytes/sec" performance monitor counter to identify which virtual network adapters are consuming the most network utilization."

Hey, this helped me already, but I have a problem:


Almost every virtual machine has 2 virtual adapters... both are "external" mode.

1 I use for a local network, AD authentication and etc.. Other one I use for internet.

How can I get a counter list on from the internet adapters?

Not sure - never heard of a setup like that... either the machines are on the internet or they are not in most configurations... not split with an AD NIC and an internet NIC.

No... actually I did not explain it well..

In my cloud I have 2 networks:

1- 10.10.0.0

2- Public IPs

These servers hava a mix of these 2 networks. One is for internal communication and other is for internet and remote accesses.
