This plugin has the ability to gather the following metrics:
| Namespace | Description |
|---|---|
| /intel/procfs/meminfo/active | The total amount of buffer or page cache memory, in bytes, that is in active use; this memory has been used more recently and usually not reclaimed unless absolutely necessary. |

| /intel/procfs/meminfo/huge_pages_rsvd | The number of huge pages for which a commitment to allocate from the pool has been made, but no allocation has yet been made. |

| /intel/procfs/meminfo/hugepagesize | The size for each hugepages unit, in bytes |
| /intel/procfs/meminfo/inactive | The total amount of buffer or page cache memory, in bytes, that are free and available; this memory has not been recently used and can be reclaimed for other purposes |
| /intel/procfs/meminfo/inactive_anon | The amount of anonymous memory, in bytes, that has not been used recently and can be swapped out |
| /intel/procfs/meminfo/inactive_file | The amount of pagecache memory, in bytes, that can be reclaimed without huge performance impact |
| /intel/procfs/meminfo/kernel_stack | The amount of memory allocated to kernel stacks in bytes |
| /intel/procfs/meminfo/low_free | The amount of memory, in bytes, that is directly mapped into kernel space. |
| /intel/procfs/meminfo/low_total | The total amount of memory, in bytes, that is directly mapped into kernel space. It might vary based on the type of kernel used. |
| /intel/procfs/meminfo/mapped | The total amount of memory, in bytes, which have been used to map devices, files, or libraries using the mmap command |
| /intel/procfs/meminfo/mem_available | The estimated amount of memory, in bytes, which is available for starting new applications without swapping |
| /intel/procfs/meminfo/mem_free | The amount of physical RAM, in bytes, left unused by the system (the sum of low_free+high_free) |
| /intel/procfs/meminfo/mem_total | Total amount of physical RAM, in bytes |
| /intel/procfs/meminfo/mem_used | The amount of physical Ram, in bytes which is used; it equals: mem_total-(mem_free+buffers+cached+slab) |
| /intel/procfs/meminfo/mlocked | The total amount of memory, in bytes, which is locked from userspace. |
| /intel/procfs/meminfo/mmap_copy | The amount of memory, in bytes, which has been used in copying mmap(). Notice that MMU is required to see this metric. |
| /intel/procfs/meminfo/nfs_unstable | The size of NFS pages, in bytes, which are sent to the server, but not yet committed to stable storage |
| /intel/procfs/meminfo/page_tables | The total amount of memory, in bytes, dedicated to the lowest page table level. |
| /intel/procfs/meminfo/quicklists | The amount of memory, in bytes, consumed by quicklists. |
| /intel/procfs/meminfo/sreclaimable | The part of Slab, in bytes, that might be reclaimed, such as caches |
| /intel/procfs/meminfo/sunreclaim | The part of Slab, in bytes, that cannot be reclaimed on memory pressure |
| /intel/procfs/meminfo/shmem | The total amount of memory, in bytes, which is shared |
| /intel/procfs/meminfo/slab | The total amount of memory, in bytes, used by the kernel to cache data structures for its own use. |
| /intel/procfs/meminfo/swap_cached | The amount of swap, in bytes, used as cache memory |

| /intel/procfs/meminfo/swap_total | The total amount of swap available, in bytes |
| /intel/procfs/meminfo/unevictable | The amount of memory, in bytes, that cannot be reclaimed (for example, because it is Mlocked or used as a RAM disk). |
| /intel/procfs/meminfo/vmalloc_chunk | The largest contiguous block of vmalloc area, in bytes, which is free |
| /intel/procfs/meminfo/vmalloc_total | The total size of vmalloc memory area in bytes |
| /intel/procfs/meminfo/vmalloc_used | The amount of vmalloc area, in bytes, which is used |
