Abstract

Technical solutions for providing real time analytics of a private area of a virtual address space are described. One general aspect includes a method that includes determining, by a processor, a start address and a size of the private area of the virtual address space. The method also includes determining, by the processor, a highest address corresponding to a user region of the private area. The method also includes determining, by the processor, a lowest address corresponding to a high-end region of the private area. The method also includes storing, by the processor, the determined information in a common area outside the virtual address space.

First claim

What is claimed is:

1. A computer implemented method for providing real time analytics of a private section of a virtual address space of a memory, the method comprising:
determining, by a processor, a start address and a size of the private section of the virtual address space;
determining, by the processor, a highest address corresponding to a user region of the private section;
determining, by the processor, a lowest address corresponding to a high-end region of the private section, wherein a storage in the user region is allocated from a first end of the private section towards the high-end region of the private section; and
storing, by the processor, the start address of the private section, the size of the private section, the highest address of the user region, and the lowest address of the high-end region in a common area of the memory that is outside the virtual address space.

2. The computer implemented method of claim 1 , wherein the private section is a portion of the virtual address space, the private section being accessible only by an application to which the virtual address space is assigned.

3. The computer implemented method of claim 2 , wherein the user region is a portion of the private section that is used for storing data and running programs in the virtual address space.

4. The computer implemented method of claim 1 , wherein the storage in the user region is allocated until a predetermined limit value of the user region is reached.

5. The computer implemented method of claim 1 , wherein the storage in the user region is allocated until a memory address contained by the high-end region of the private section is reached.

6. The computer implemented method of claim 5 , wherein a storage in the high-end region of the private section is allocated from a second end of the private section towards the user region of the private section.

7. The computer implemented method of claim 6 , wherein the high-end region is a portion of the private section that is used for storing data structures associated with the virtual address space.

8. The computer implemented method of claim 1 , wherein determining the lowest address corresponding to the high-end region of the private section further comprises:
determining, by the processor, a current size of the user region of the private section;
determining, by the processor, a size of a free block that starts from a memory address corresponding to the current size of the user region; and
assigning, as the lowest address corresponding to the high-end region of the private section, a memory address corresponding to the size of the free block starting from the current size of the user region.
