Answer 1

Note that tailing an aws log is now a supported feature of the official awscli, albeit only in awscli v2, which is not released yet. Tailing and following the logs (like tail -f) can now be accomplished by something like:

aws logs tail $group_name --follow

To install the v2 version, see the instructions on this page. It was implemented in this PR. To see it demonstrated at the last re:Invent conference, see this video.

In addition to tailing the logs, it allows viewing the logs back to a specified time using the --since parameter, which can take an absolute or relative time

aws logs tail $group_name --since 5d

To keep the v1 and v2 versions of awscli separate, I installed awscli v2 into a separate python virtual environment and activate it only when I need to use awscli v2.
