Description

The GET MEMORY STATISTICS command recovers information related to the use of the data cache by 4D. This information can be used to analyze the functioning of the application.

In the infoType parameter, pass a value indicating the type of information that you want to obtain:

1 = General memory information. This information is also available via the Runtime Explorer: size of physical, virtual, free and used memory, stack memory and free stack memory, etc.
2 = Summary of database cache occupancy statistics (4D 32-bit only).

Compatibility Note: Value 2 is deprecated for 4D 64-bit versions. For these versions, we recommend using the Cache info command to get cache statistics.

After the command has been executed, the statistics are provided in the arrNames, arrValues and arrCount arrays. For more information about advanced interpretation of this data, please contact your local Technical Service department.
