CloudWatch Logs & Alerts
Viewing CloudWatch Logs
When you created your database in the first lab you selected to publish logs to CloudWatch. Both the database and upgrade logs can be found in a CloudWatch Log Group associated with your database.
Amazon CloudWatch allows us to consolidate logs from various AWS services into a single location to help draw correlations between services, like the application plane and Amazon RDS database.
Open CloudWatch Logs enter /aws/rds into the filter box and hit enter. Select the group assoicated with your database rds-pg-labs and take a look at the log stream.
