AWS Server Monitoring

Our environment is setup like this -

Elastic Load Balancer ----> into 3 Server instances with Ubuntu-64. This is supporting our web application. Our concern is the amount of traffic we receive and being able to monitor and spin up another server if the above 3 servers happen to reach capacity. And, if possible, not have to worry about getting a call at 3am saying the servers are down (not possible)

Does anyone have any ideas on how to 1. monitor the servers and receive reports of usage, traffic, etc.. 2. if they reach thresholds of a certain amount, have AWS spin up a new server?

Any ideas or other thoughts how to manage this would be great! Appreciate all the help!

Hi,

With regards to usage reports of traffic etc, you can use Cloudwatch for both EC2 instances and your ELB which will display useful statistical information on various usages.  More info on Cloudwatch can be found here:
https://aws.amazon.com/cloudwatch/

Info on using Cloudwatch with EC2 and ELB can be found here:
http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/elb-cloudwatch-metrics.html
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-cloudwatch.html

With regards to your instances self healing and spinning up further instances depending on thresholds you can use Auto Scaling to complete this which works great with ELB.  More info on Auto Scaling can be found here:
https://aws.amazon.com/autoscaling/

To configure auto scaling please see the following instructions:

Information on how to use auto scaling with your ELB can be found here:

Hope this helps!

Cheers,
