This topic describes how to go to the data overview page to view information about all compute engines that belong to your Alibaba Cloud account in the current region.

Procedure

Go to the Data Map page.
Log on to the DataWorks console. In the top navigation bar, select the desired region. In the left-side navigation pane, choose Data Catalog > Data Map. On the page that appears, click Go to Data Map.
In the middle of the right side of the homepage of Data Map, click Data Overview next to Collect Metadata.

On the data overview page, view information about all compute engines that belong to your Alibaba Cloud account in the current region.

The following figure shows the statistics on the MaxCompute compute engine data.

Item	Description
Total Number of Projects	The total number of MaxCompute projects that belong to the current tenant in the current region. The number of MaxCompute projects is collected in real time.
Total Number of Tables	The total number of tables in the MaxCompute projects that belong to the current tenant in the current region. The information is collected in offline mode and is updated with a delay of one day.
Storage	The logical storage space that is occupied by all tables in the MaxCompute projects that belong to the current tenant in the current region. The logical storage space includes the space that is occupied by temporary files of auto triggered tasks and the space that is not released after tables are deleted. The information is collected in offline mode and is updated with a delay of one day.
Total APIs	The total number of MaxCompute APIs that are published to API Gateway up to the current time for the current tenant in the current region.
Storage Trend Chart	The trend chart of the logical storage space that is occupied by all MaxCompute projects for the current tenant in the current region. The logical storage space includes the space that is occupied by temporary files of auto triggered tasks and the space that is not released after tables are deleted. The information is collected in offline mode and is updated with a delay of one day.
Top Projects by Table Storage	The MaxCompute projects that occupy the most logical storage space for the current tenant in the current region. The information is collected in offline mode and is updated with a delay of one day.
Top Tables by Occupied Storage	The MaxCompute tables that occupy the most logical storage space. You can click a table name to go to the details page of the table. The information is collected in offline mode and is updated with a delay of one day. Note The Top Projects by Table Storage and Top Tables by Occupied Storage sections display the logical storage space that is occupied by MaxCompute projects and the logical storage space that is occupied by MaxCompute tables. The statistics are generated and collected in offline mode. The logical storage space displayed for each project includes the logical storage space occupied by tables, resources, recycle bins, and files of other systems. As a result, the logical storage space displayed for each project is greater than the logical storage space occupied by tables in the project. You are charged for the logical storage space of tables but not the physical storage space of tables.
Most Frequently Used Tables	The tables that are most frequently accessed. The statistics are generated based on the number of views of the details page of each table. The statistics on Most Frequently Used Tables are collected in real time.
