Overview Panel¶
To the right of the Filters panel and occupying the upper part of the dashboard is the Overview panel.
Each row of the table represents the metrics for a chosen object type, one of:
- Query;
- Service Name;
- Database;
- Schema;

- Client Host.
At the top of the second column is the dimension menu. Use this to choose the object type.
On the right side of the dimension column is the Dimension Search bar.
Enter a string and press Enter to limit the view to queries containing only the specified keywords.
Delete the search text and press Enter to see the full list again.
Columns¶
- The first column is the object’s identifier. For Query, it is the query’s Fingerprint.
- The second column is the Main metric, containing a reduced graphical representation of the metric over time, called a sparkline, and a horizontal meter, filled to reflect a percentage of the total value.
- Additional values are revealed as mouse-over tool-tips.
Tool-tips¶
- For the Query dimension, hovering over the information icon reveals the query ID and its example.
- Hovering on a column header reveals an informative tool-tip for that column.
- Hovering on the main metric sparkline highlights the data point and a tooltip shows the data value under the cursor.
