CloudWatch is an monitoring and observability platform that was designed to give us insight into our AWS architecture. It allows us to monitor multiple levels of our applications and identify potential issues

CloudWatch Features

  • System Metrics
  • Application Metrics : information inside EC2
  • Alarms: Alarms us when something’s wrong

Application Monitoring Using CloudWatch Logs

What do we do with our logs which comes from: EC2, RDS, LAMBDA, CloudTrail, On-Premises

=> CloudWatch logs allow you to monitor, store, and access log files from variety sources

Terms:

  • Log Event: timestamp + data, log entry
  • Log Stream: A collection of log events come from the same source creates a log stream. Think of continuous set of logs from a single instance.
  • Log Group: Collection of log streams. Eg: you would like to group all your Apache web server logs across hosts together

Features:

  • Filter Patterns: You can look for specific terms in your logs. Think 400 errors in your web server logs.
  • CloudWatch Logs Insights: This is allow you to query all your logs using SQL-like interactive solution
  • Alarms: Once you’ve identified your trends or patterns, it’s time to set up alerts for them

Logs should Go to CloudWatch Logs

  • Except for situations where we don’t need to process them. Then they should go straight to S3.
