| Available memory size | com.dynatrace.extension.host-observability.host.memory.bytes.available | - | Byte |
| Commited memory size | com.dynatrace.extension.host-observability.host.memory.bytes.commited | Committed Bytes is the amount of committed virtual memory, in bytes. | Byte |

| Commit limit | com.dynatrace.extension.host-observability.host.PerfOS_Memory.CommitLimit | Commit Limit is the amount of virtual memory that can be committed without having to extend the paging file(s) | Byte |
| Free and Zero page list bytes | com.dynatrace.extension.host-observability.host.PerfOS_Memory.FreeAndZeroPageListBytes | Free & Zero Page List Bytes is the amount of physical memory, in bytes, that is assigned to the free and zero page lists. This memory does not contain cached data. It is immediately available for allocation to a process or for system use. | Byte |
| Free system page table entries | com.dynatrace.extension.host-observability.host.PerfOS_Memory.FreeSystemPageTableEntries | Free System Page Table Entries is the number of page table entries not currently in used by the system. This counter displays the last observed value only; it is not an average. | Count |

| Pages input per second | com.dynatrace.extension.host-observability.host.PerfOS_Memory.PagesInputPersec | Pages Input/sec is the rate at which pages are read from disk to resolve hard page faults. Hard page faults occur when a process refers to a page in virtual memory that is not in its working set or elsewhere in physical memory, and must be retrieved from disk. | PerSecond |
| Pages output per second | com.dynatrace.extension.host-observability.host.PerfOS_Memory.PagesOutputPersec | Pages Output/sec is the rate at which pages are written to disk to free up space in physical memory. Pages are written back to disk only if they are changed in physical memory, so they are likely to hold data, not code. | PerSecond |
| Pages per second | com.dynatrace.extension.host-observability.host.PerfOS_Memory.PagesPersec | Pages/sec is the rate at which pages are read from or written to disk to resolve hard page faults. This counter is a primary indicator of the kinds of faults that cause system-wide delays. | PerSecond |
| System cache resident bytes | com.dynatrace.extension.host-observability.host.PerfOS_Memory.SystemCacheResidentBytes | System Cache Resident Bytes is the size, in bytes, of the portion of the system file cache which is currently resident and active in physical memory. | Byte |
| Transition pages repurposed per second | com.dynatrace.extension.host-observability.host.PerfOS_Memory.TransitionPagesRePurposedPersec | Transition Pages RePurposed is the rate at which the number of transition cache pages were reused for a different purpose. | PerSecond |
