Article says that logging to a non-production db "isn't a HORRIBLE idea" indicating that it isn't really a good idea. I used to work with a system where we routinely made complex queries against the log database. Parsing the log line before inserting to the db, putting relevant values into indexed columns seemed to me like a pretty good idea and provided us with a really easy-to-use and a rather fast diagnostics tool that no one had to learn how to use. EDIT: Of course you have to make sure you don't do any writes that block the main operation, e.g. by using message queues.
