Now Amazon CloudWatch Metrics assisted by Amazon VPC Traffic Mirroring

Amazon Virtual Private Cloud (Amazon VPC) allows you to initiate AWS resources into a virtual network which you have described. This virtual network strongly looks like a traditional network which you'd run in your own data centre, with the advantages of utilising the scalable infrastructure of AWS. And Traffic Mirroring is a feature of Amazon VPC that you can utilise to clone network traffic from an elastic network interface of Amazon EC2 instances. You can then send the traffic to out-of-band security and monitoring appliances for:

• Content inspection
• Threat monitoring
• Troubleshooting

Now you can use Amazon CloudWatch to observe metrics linked with VPC Traffic Mirroring. You can gather data like amount of traffic mirrored or not mirrored on your network interface which is a component of a traffic mirror session and creates readable, near real-time metrics. And this information can be used to observe and troubleshoot Traffic Monitoring. Additionally you can enable CloudWatch Alarms to get notifications on any metrics crossing pre-defined thresholds. To begin with these metrics, refer Monitoring Mirrored Traffic Using Amazon CloudWatch. And to know in detail on Amazon CloudWatch, go through the Amazon CloudWatch User Guide and for pricing see Amazon CloudWatch Pricing.
