Take memory snapshot

This command copies the contents of the process memory to the database. Available during debugging session

The contents of the memory are copied to the database. Users can specify that only segments with the 'loader' attribute be stored in the database.

Segments with loader attributes are created by the input file loader and usually contain information from the input file. However, in some cases (such as attaching to an existing process), IDA does not load the input file, so there may be no loader segment.

To enable partial snapshots to be created in this and other similar situations, the user can set or clear the "loader" attribute of the desired segment using the edit segment command.

After applying this command, the user can terminate the debugging process and continue analyzing the programs in the database.

Please be aware that you can save the database without taking a snapshot of memory. Such databases may be used to store global information about programs such as breakpoint information, comments, and so on. However, we recommend that you use a memory snapshot of at least the "loader" segment, since you can store information about programs, names, comments etc at least.

When debugging using the integrated memory usage diagnostic tool of the debugger, you will find memory leaks and inefficient memory. Using the Memory Usage tool, you can create one or more snapshots of managed memory and native memory heap to understand the impact of object type on memory usage. You can collect snapshots of .NET, native, or mixed mode (.NET and native) applications. You can collect memory snapshots at any time with the Memory Usage tool, but you can use the Visual Studio debugger to control the behavior of the application when investigating performance problems. Setting breakpoints, stepping, full interrupts, and other debugger operations can help you focus performance investigations on the most relevant code paths. Running these actions while the application is running will eliminate noise from uninteresting code and can greatly reduce the time required to diagnose the problem.

The snapshot is initially stored in the renderer process memory. When you click on the snapshot icon and display it, they are transferred to DevTools as needed. When the snapshot is loaded and parsed into DevTools, the number under the title of the snapshot is displayed and the total size of accessible JavaScript objects is displayed. The top entry is the "total" line. Display the constructor name and group all the objects created by this constructor. The number of object instances is displayed in the # column. The Shallow Size column indicates the shallow size sum of all objects created by a particular constructor. The Retention Size column shows the maximum retention size in the same set of objects.
