Query History Chart

The Query History Chart provides an overview of the queued query time, the number of queries which had to wait for a read ticket as well as the ones that were denied. That way, you can easily check for bottlenecks or peaks in your queries and, if necessary, increase the number of read tickets.

The queued query time chart displays the time a query had to wait until a read ticket was available.

The queued or denied read tickets chart displays the number of queries that had to wait for a read ticket and also the number of queries that were denied due to too many queries waiting at the same time.

To find out more about read ticket management concepts, refer to Read Ticket Management.

Proceed as follows

Click the Query History Chart menu item.

→ The Query History Chart is displayed and shows two charts on the queued query time and the queued as well as denied read tickets.



To access the query history chart, you have to be assigned to the Admin role.
