By "log messages" do you mean like slf4j/printf/etc text streaming out of the services as they're running? Or Kafka topics/event streams/etc?

If it's the former, this title is inaccurate as this tool has nothing to do with debug logging.
If it's the latter, I think "log analysis" is a confusing term, as it makes me think of text logging.

[gharris1727]

I think it's odd to say that the logs are CSV-formatted. It's "output", "data", or a "result", logs are something separate.

Is this something that the customer can do? Is this appropriate for this customer facing document?

[gharris1727]

I think this table has too many columns and doesn't render well on a web page.

Certain things can be combined or removed: The message ID is not part of the script output and it's only in this document to be used in talking about problems between customers and Support. It could be a superscript, or combined with the "Script message" column or whatever.

The Customer Action and Issue with Apache Kafka..." columns could also be combined, or the "Isssue with..." column could be discarded.
