ABSTRACT:
A system and apparatus is described to check pages in memory that are allocated to all processes and the operating system, and to check the pages in memory that are allocated to each individual process, in order to determine total RAM usage and RAM usage for a particular process, respectively. In order to determine total RAM usage for all processes and the operating system, a page frame table is used to count all memory pages being used. System memory pages, all process pages and unassigned pages are marked in a page frame table using a specific marking process. These marked pages are then summed and categorized for their particular usage, i.e. free memory, system memory or process memory. The RAM memory usage for a particular process can also be determined. First, RAM usage from operating system control blocks assigned to the specific process is computed. Next, the private memory area and shared memory area used by the process is determined by finding the pages associated with a memory object and counting the actual pages being used. The counted pages are then added to determine the total RAM in use for the particular process.
