### Setting up Netsense packet sensor with right traffic feeds in AWS

The functionality of Netsense packet sensor software truly depends on the right traffic fed to it in your public cloud IT network. Selecting right computing instances to monitor in your AWS public cloud IT network is crucial for efficient network performance monitoring(NPM). Getting visibility into internal communication of your various business critical computing instances/VMs in your AWS cloud is critical for efficient monitoring. VMs/Computing instances running critical application services should be chosen to monitor.

**Setting up traffic mirroring in virtual private cloud(VPC) in AWS**

AWS provides traffic mirroring capability to pick and choose VMs/Computing instances you wish to monitor traffic. The target destination will be the Netsense VM running in your same VPC network as your other VMs.

The below link provides guidance to setting up traffic mirroring in AWS VPC networks.

[What is Traffic Mirroring? - Amazon Virtual Private Cloud](https://docs.aws.amazon.com/vpc/latest/mirroring/what-is-traffic-mirroring.html)

Alternatively, if you do not wish to use traffic mirroring capability in AWS, you can choose to install ThoughtData's NetMirror software on your business critical application server VMs, which you wish to monitor and stream the traffic to your Netsense VM/Computing instance.

**Using NetMirror software from ThoughtData on your VMs in AWS**

NetMirror software from ThoughtData provides capability to stream traffic from one or more vNICs on your VMs to a destination Netsense VM. The destination Netsense VM should be in same VPC as your source VMs. NetMirror software from ThoughtData is a replacement for traffic mirroring functionality offered by your AWS.

NetMirror software uses very minimal resources on your VM and continuously captures and streams traffic from source VMs to Netsense VM using high data compression. One Netsense sensor can get traffic streams from multiple NetMirrors. NetMirror software is only a layer 3 function and does not interfere with any other communications or applications on your VM.

For guidance to setting up NetMirror in a public cloud refer to the topic in the link below:
