Is there any way of logging in the results.log the name of the table that the logs are from? rather than the arbitrary 'pack_xyz' identifier at the start of each result

Logs could come from multiple tables — typically its best to provide a name for the query in the pack that would help you identify it later

You can also manually tag the log at query time (see screencap), but like @zwass said, it is common for a query to

join

multiple tables

The logs include the "name" of the query as specified in the pack (see https://github.com/facebook/osquery/blob/experimental/packs/hardware-monitoring.conf#L3).

I was hoping for there to be some way of modifying a configuration parameter to include the name of the actual table in the event itself and not reliant on an arbitrary name for the query

This functionality doesn’t exist, but it is definitely an interesting idea.
