Summary
In this chapter, we learned how to derive operational intelligence from CloudWatch metrics using the metrics explorer and query metrics using CloudWatch Metrics Insights. We looked at how to derive operational intelligence using metric match expressions and search expressions, and also how to use anomaly detection in metrics. Further, we explored leveraging CloudWatch Application Insights to observe an application running on an EC2 instance and gather metrics and log files, and how observability onboarding can be simplified during Day 2 operations with ease. We learned how to derive operational metrics from CloudWatch Logs and how to leverage CloudWatch Logs Insights to understand log files in a better way. Finally, we discussed CloudWatch Contributor Insights and how that can be used to understand the top contributors from DynamoDB tables and the supported log formats for CCI.
