Timeouts

Expand the “Timeouts” row to view a chart that shows the number of timeouts for each database.

Query timeouts occur when a client, application, or command exceeds its configured timeout before the operation completes. QMonitor captures timeout events and records the error text, session details, and, when available, the SQL text.

Under the chart is a list of timeout events with columns for time, sequence, database, duration, application, username and duration. Use the column filters and sort controls to filter and sort the table.

Click a row to open the Timeout detail dashboard.

The top table in the detail view shows the same event information as the events dashboard. The Timeout Statement panel displays the SQL statement found int the timeout event. The SQL text may be unavailable for some event types.

The bottom grid lists sessions that were running around the event time, giving a quick overview of related activity. Use the buttons above the grid to set the time window around the event from 1 to 15 minutes.

Investigate frequent timeouts by reviewing the SQL, execution plan, and wait types. Consider query tuning or indexing, increase client timeouts only after identifying the root cause, or add retry logic where appropriate.
