Abstract
In an embodiment, a problem record associated with a query is saved to a log if the query encountered a problem. The amount of data in the record is increased if an access plan associated with the query has changed within a threshold amount of time and decreased if the access plan has not changed. In various embodiments, the problem is that the query executes longer than a historical average for the query, the query executes longer than a threshold, or the query encounters a functional error. In an embodiment, a benchmark record is also saved to the log, the problem record is compared to the benchmark record, and the difference is presented. In various embodiments, an oldest record is periodically removed from the log, or an oldest record is removed from the log if the associated query has more than a threshold number of records.
