On the Resource Groups page of the DataWorks console, you can monitor the resource usage, usage trends, running tasks, and queuing tasks of an exclusive resource group in real time. You can also monitor the resource usage of specific tasks and adjust inefficient resource use at the earliest opportunity.
View resource usage
Log on to the DataWorks console.
In the top navigation bar, select the region where your exclusive resource group resides. In the left-side navigation pane, click Resource Group. The Exclusive Resource Groups tab appears.
On the Exclusive Resource Groups tab, find the exclusive resource group you want to monitor and click the value in the Used CUs column.
The resource usage details page appears.
The information displayed on the details page varies based on the resource group type. You can view the information displayed for different types of resource groups in the DataWorks console.

Interpret the data and take action
Running and queuing tasks
If the number of queuing tasks is high, your exclusive resource group may be at capacity. A task that runs for a long time holds resources and can block other tasks from starting. The maximum number of concurrent tasks depends on the resource group specifications and the total number of resources. For billing and capacity details, see Billing of exclusive resource groups for scheduling (subscription) and Billing of exclusive resource groups for Data Integration (subscription).
Scaling out or in
When you scale out or in, the added or removed resources must match the specifications you selected at purchase time.
What's next
If tasks are still blocked after reviewing resource usage, see Nodes that are not run for further troubleshooting.
