The October issue of Linux Journal carried the first product announcement on ExtSQL. Our thanks to them! We'd like to provide a direct link to the article at their web

Here is an excerpt:

Software Workshop's ExtSQL

Enriching the vast MySQL ecosystem is the new ExtSQL, short for Extended usage statistics for SQL. The product is designed to provide DBAs with a simple tool for monitoring database activity by individual user, database, host or even connection. Software Workshop asserts that present SQL monitoring tools allow only gross monitoring at the server level. ExtSQL provides extra detail, including historical data, and makes it available from the command line. The ExtSQL server is designed to be a drop-in replacement for an existing mysqld or postmaster executable.
