A lot of applications are generally responsible and close the connection properly. I’m more interested in slow queries that bog down the database across HTTP (Apache). We also use a common database layer. An alternate approach is to simply track the HTTP requests that take a long time and, specifically, the one SQL query that hung up the page. We use PHP, so we can also dump a call stack and put serialize()’d request data into the database. If the user has already waited more than 5 seconds for a response, what is an extra 20ms? To do this, modify the database layer to make one extra SQL query to a “long queries” table that contains all the information you think you will need to diagnose issues.
