rrupt
phantom interrupts
Incremented on each phantom interrupt
traps
Not maintained by the operating system.
syscalls
Incremented for each system call.

Notes:
- When used with the -p pagesize option, the -s option appends the sum structure for the specified page size to the system-wide sum structure. This additional stanza is preceded by a page size header (for example, 4K pages). The following details are not be displayed in this pagesize-based stanza as these statistics are not related to page sizes:
- Processor context switches
- Device interrupts
- Software interrupts
- Decrementer interrupts
- MPC-sent interrupts
- MPC-received interrupts
- Phantom interrupts
- Traps
- Syscalls
- When the -s flag is used with the -l flag, the vmstat command displays the following metric:
-
large-page hi water count
-
Specifies the maximum value of the large-page inuse count.
|
| -t |
Prints the time-stamp next to each line of output of vmstat. The time-stamp is displayed in the HH:MM:SS format. Note: Time stamp will not be printed if -f, -s, or -i flags are specified. |
| -v |
Writes to standard output various statistics maintained by the Virtual Memory Manager. The -v flag can only be used with the -s flag.
-
memory pages
-
Size of real memory in number of 4 KB pages.
-
lruable pages
-
Number of 4 KB pages considered for replacement. This number excludes the pages used for VMM internal pages, and the pages used for the pinned part of the kernel text.
-
free pages
-
Number of free 4 KB pages.
-
memory pools
-
Tuning parameter (managed using
vmo) specifying the number of memory pools.
-
pinned pages
-
Number of pinned 4 KB pages.
-
maxpin percentage
-
Tuning parameter (managed using
vmo) specifying the percentage of real memory which can be pinned.
-
minperm percentage
-
Tuning parameter (managed using
vmo) in percentage of real memory. This specifies the point below which file pages are protected from the re-page algorithm.
-
maxperm percentage
-
Tuning parameter (managed using
vmo) in percentage of real memory. This specifies the point above which the page stealing algorithm steals only file pages.
-
numperm percentage
-
Percentage of memory currently used by the file cache.
-
file pages
-
Number of 4 KB pages currently used by the file cache.
-
compressed percentage
-
Percentage of memory used by compressed pages.
-
compressed pages
-
Number of compressed memory pages.
-
numclient percentage
-
Percentage of memory occupied by client pages.
-
maxclient percentage
-
Tuning parameter (managed using vmo) specifying the maximum percentage of memory which can be used for client pages.
-
client pages
-
Number of client pages.
-
remote pageouts scheduled
-
Number of pageouts scheduled for client filesystems.
-
pending disk I/Os blocked with no pbuf
-
Number of pending disk I/O requests blocked because no pbuf was available. Pbufs are pinned memory buffers used to hold I/O requests at the logical volume manager layer.
-
paging space I/Os blocked with no psbuf
-
Number of paging space I/O requests blocked because no psbuf was available. Psbufs are pinned memory buffers used to hold I/O requests at the virtual memory manager layer.
|
| -v |
(Statistics displayed by -v, continued):
-
filesystem I/Os blocked with no fsbuf
-
Number of filesystem I/O requests blocked because no fsbuf was available. Fsbuf are pinned memory buffers used to hold I/O requests in the filesystem layer.
-
client filesystem I/Os blocked with no fsbuf
