Analyzing the network traffic between virtual

machines

More and more enterprises are using virtualization technology. By running multiple virtual machines on
one VMware server, you can improve the physical server usage, reduce the hardware investments, and

reduce the power consumption of the data center.
Virtual machines running on the same VMware server can provide more types of services for network

users at the same time. Each virtual machine has its own IP/MAC address. Therefore, all traffic passing

through the devices can be captured by the device supporting NetStream v5/v9, NetFlow v5/v9, or
sFlow v5, and sent to NTA for processing and analysis. However, because the traffic between virtual

machines is internally forwarded by the vSwitches of the VMware server without passing through the

devices, such traffic cannot be captured and forwarded to NTA for processing and analysis.
IMC provides the probe server for analyzing the traffic between virtual machines.
The IMC probe servers include Linux servers with probe application programs installed and vMON

virtual machines.

When the Linux servers with probe application programs installed are used, the operators must
create a virtual Linux server on the VMware server and deploy a probe application program on the

virtual Linux server. After the deployment, the operators must set the vSwitch. For information about
using the probe to analyze the traffic between virtual machines, see "

14 Analyzing traffic between

virtual machines

."

When the vMON virtual machines are used, the operators must import vMON on the VMware
server, and set the vSwitch after importing the vMON. For more information about the vMON

usage, see vMON Administrator Guide.
