Unit |
Interpretation |
| Memory_pages |
Indicates the size of the real memory in KBytes. |
KBytes |
4 Kb equals to 1 page. |
| Iruable_pages |
Indicates the number of 4 KB pages considered for replacement. |
Number |
This number excludes the pages used for VMM(Virtual memeory manager) internal pages, and the pages used for the pinned part of the kernel text.
|
| Free_pages |
Indicates the number of pages that are currently used by the file cache. |
Number |
|
| Memory_pools |
Indicates the number of memory pools. |
Number |
|
| Pinned_pages |
Indicates the pages that are currently in use. |
Number |
|
| Maxpin |
Indicates the maximum percentage of real memory that can be replaced. |
Number |
|
| Minperm |
Indicates the minimum amount of memory that should be used for non-computational pages.
|
Number |
The number of non-computational pages is referred to as numperm;It is the limit below which the file pages are protected from the re-page algorithm.
|
| Maxperm |
Indicates the maximum amount of memory that should be used to cache non-computational pages.It is the limit above which the page stealing algorithm steals only file pages. |
Number |
|
| Numperm |
Indicates number of non-computational pages is referred to as numperm; It is the percentage of memory that are currently used by the file cache. |
Number |
|
| File_pages |
Indicates the number of pages that are currently used by the file cache. |
Number |
|
| Compres_pct |
Indicates the percentage of memory that are relatively compressed. |
Number |
|
| Compres_pages |
Indicates the number of unused pages that are relatively compressed and stored in memory. |
Number |
|
| Numclient_pct |
Indicates the number of non-computational client pages; It is percentage of memory occupied by client pages. |
Number |
|
| Maxclient_pct |
Indicates a limit on the maximum amount of memory that should be used to cache non-computational client pages; It is the maximum percentage of memory which can be used for client pages. |
Number |
Because all non-computational client pages are a subset of the total number of non-computational permanent storage pages, the maxclient limit must always be less than or equal to the maxperm limit.
|
| Client_pages |
Indicates the number of client pages. |
Number |
|
| Remote_pageouts |
Indicates the number of pageouts scheduled for client file systems. |
Number |
|
| Pending_disk |
Indicates the number of pending disk I/O requests that have been blocked since the pbuf are not available. |
Number |
Pbufs are pinned memory buffers used to hold I/O requests at the logical volume manager layer.
|
| Paging_space |
Indicates the number of paging space I/O requests that have been blocked since the psbuf are not available. |
Number |
Psbufs are pinned memory buffers used to hold I/O requests at the virtual memory manager layer.
|
| Filesystem |
Indicates the number of filesystem I/O requests that have been blocked since the fsbuf are not available. |
Number |
Fsbuf are pinned memory buffers used to hold I/O requests in the filesystem layer.
|
| Client_filesys |
Indicates the number of client filesystem I/O requests that have been blocked since the fsbuf are not available. |
Number |
NFS (Network File System) and VxFS (Veritas) are client filesystems. Fsbuf are pinned memory buffers used to hold I/O requests in the filesystem layer.
|
| Ext_pager_filesys |
Indicates the number of external pager client filesystem I/O requests that have been blocked since the fsbuf are not available. |
Number |
JFS2 is an external pager client filesystem. Fsbuf are pinned memory buffers used to hold I/O requests in the filesystem layer.
