Best Practices for Monitoring
Use the following best practices for monitoring to help you with your Amazon EC2 monitoring tasks.
Make monitoring a priority to head off small problems before they become big ones.
Create and implement a monitoring plan that collects monitoring data from all of the parts in your AWS solution so that you can more easily debug a multi-point failure if one occurs. Your monitoring plan should address, at a minimum, the following questions:
What are your goals for monitoring?
What resources you will monitor?
How often you will monitor these resources?
What monitoring tools will you use?
Who will perform the monitoring tasks?
Who should be notified when something goes wrong?
Automate monitoring tasks as much as possible.
Check the log files on your EC2 instances.
