Abstract
Database systems are subject to automatic troubleshooting. Query execution data for individual queries executed by a database system can be collected. The query execution data can be evaluated automatically in conjunction with one or more detection metrics to determine whether or not a potential performance issue exists. After detection of a potential issue, the query execution data can be analyzed further to determine one or more causes by matching query execution data to one or more patterns that encode candidate causes. Subsequently, a root cause amongst multiple causes is determined based on causal dependency. Corrective action associated with a root cause can also be determined and optionally applied automatically.
