Chapter 12 - Monitoring

Question 1

CloudWatch

Answer 1

There are limitations to CloudWatch where another tool
might be able to fill in that gap.

• Is the main tool for anything alarm metric monitoring related
• It works on-prem,
• It works with EC2
• It’s the place for logs
• It works with RDS
• It works with Lambda
• It works with CloudTrail
• It’s very simple to get set up with
• So system-level, application-level…think CloudWatch.
• Your metrics are delivered every 5 minutes
• And if you opt in for detailed metrics, you’ll see those every 1 minute
• The 5-minute metrics are free
• The 1-minute metrics include an additional charge.

It’s also important to know that if your metrics come in every 5 minutes but your alarm is set to look for data points every 1 minute, you will be stuck in the insufficient data purgatory forever and your alarm will never work correctly.

• You need to know on-prem, EC2, RDS, Lambda, CloudTrail all integrate with this service.
• You have the ability to stream them into CloudWatch Logs.
