  • working_set_size
  • quota_peak_paged_pool_usage
  • quota_paged_pool_usage
  • quota_peak_non_paged_pool_usage
  • quota_non_paged_pool_usage
  • pagefile_usage

• total_phys - The amount of total physical memory.
• avail_phys - The amount of still available physical memory.
• total_pagefile - The amount of total pageable memory (physical memory + paging file).
• avail_pagefile - The amount of still available pageable memory (physical memory + paging file).
• total_virtual - The amount of total virtual memory for a process.
