Listing Log Groups with aws logs describe-log-groups

When you want to see where logs are being collected, use aws logs describe-log-groups. It lists the CloudWatch log groups.

The syntax is aws logs describe-log-groups. A prefix filters the results.

Running it returns each group's name, creation time, retention setting and stored size.

A common stumble is finding groups with no retention policy at all, holding years of logs nobody will read.

In real work, it is the starting point for investigating an incident — and for the periodic cleanup that keeps costs sane.
