Understand

Every application is different—they all have their own particular signatures. When monitoring your application regularly with the tools we have described, you will get to know that signature. You will know when to expect your CPU to spike because of a reporting cron job, or what the normal traffic graph is. And anything out of the ordinary is worth a closer look.

There is a wealth of information available through CloudWatch, and with some effort, you can correlate different graphs. What you can’t read from the graphs is why traffic spiked, and it’s not always the application that is misbehaving. It’s important to talk to everyone involved so you can figure out what happened, but more importantly, you will start to learn what to expect. After all, before you can conclude something is fishy, you need to have expectations.
