# Top tasks

The Top Tasks dashboard provides a summary of activity and performance metrics for the given time frame and filter set. It also provides a bubble chart comparing three key metrics for your top tasks together with a corresponding data grid. You can customize the bubble chart by selecting the number of tasks to view and the three metrics to plot, including the Rank By metric, the X-Axis metric and the Y-Axis metric. You can also choose whether to rank the bubble chart data in Ascending or Descending order. The grid can be further customized as described in [Customizing task columns](https://help.qlik.com/en-US/enterprise-manager/November2025/Content/EnterpriseManager/Main/Tasks/Customizing_Task_Columns.htm).

For the specified filters, the Top Tasks dashboard displays the following key metrics:

* [Server utilization](https://help.qlik.com/en-US/enterprise-manager/November2025/Content/EnterpriseManager/Main/Analytics/trends_top_tasks.htm#Server)
* [Full load](https://help.qlik.com/en-US/enterprise-manager/November2025/Content/EnterpriseManager/Main/Analytics/trends_top_tasks.htm#Full)
