Missing Analysis Output

Hello,

We've launched the CF template and ran the SF. However, at the end of the process the performance metrics are _not_ available to query. We're currently just testing the tool and rerunning a handful of queries with the simple replay log configuration. The cluster has audit_logging and user_activity enabled. We do not have a ddl_and_copy and sql_script configured. We are not overwriting the replay or extraction configuration.

At the moment we're using it within the same account as the initial Redshift Cluster and Snapshot - but this is a staging account. For production we will use it across account.

Having a look at the logs we can see a few things suspect things,

From the lambda function we can see an unload to (s3://bucket/data/raw_results) and the table it's trying to unload (public.redshift_config_comparison_raw). However, there is no data in S3, and there's no data for the table in Redshift.

Stepping back another layer, we noticed in the batch logs there was a line that stated:`Analysis not enabled for this replay.`

From what I can see the `replay_bootstrap.sh` does not set an `analysis_output` or `analysis_iam_role` for the SimpleReplay config, which ultimately results in the`Analysis not enabled for replay` line. Should Analysis be enabled?

We've been following the [blog](https://aws.amazon.com/blogs/big-data/compare-different-node-types-for-your-workload-using-amazon-redshift/) and readme, but there's nothing (we can see) about enabling analysis. It sounds like it _should_ be the expected output.

I'm wondering if you could give us some pointers to where we should begin to dive into this.
