Process Memory Statistics

• The statm entry contains a list of seven numbers, separated by spaces. Each number is a count of the number of pages of memory used by the process in a particular category. The categories, in the order the numbers appear, are listed here:
  1. The total process size.
  2. The size of the process resident in physical memory.
  3. The memory shared with other processes; that is, memory mapped both by this process and at least one other (such as shared libraries or untouched copy-on-write pages).
  4. The text size of the process; that is, the size of loaded executable code.
  5. The size of shared libraries mapped into this process.
  6. The memory used by this process for its stack.
  7. The number of dirty pages; that is, pages of memory that have been modified by the program.
