Using the AWS CLI can be a bit irritating because the stream name changes as you modify your function. I've found that using awslogs (https://github.com/jorgebastida/awslogs) is a nicer workflow.

List the groups:

Filter results.

Then get the logs from the group.

It defaults to the last 5 minutes, but you can add the -s parameter to choose a time, e.g -s 10m for the last 10 minutes.

The output is colourised if you're at the terminal, or plain if you're piping it through other commands, e.g. grep to find something.
