VividCortex captures raw samples of the queries that are sent to your database, in addition to aggregate query metrics. This provides richer detail into query activity, especially slow queries or queries which generate errors, and also lets you examine execution plans for opportunities for optimization.

Note: You will need to have VividCortex configured to capture query samples to use this page.

- database: The database the query was executed against, provided either at the time of connection or by using the
- user: The user that ran the query.
- origin: The IP address and port of the client which issued the query.
- latency: The query latency, in seconds. You can specify both a minimum and maximum.
- connection ID: The connection ID of the query execution.
All fields are treated by default as exact matches, and multiple search parameters are combined with AND. You

us_* would match everything beginning with
