vmstat output explained - Solaris - Каталог статей

Category	Field Name	Description
`procs`		Reports on the following:
	`r`	The number of kernel threads in the dispatch queue
	`b`	The number of blocked kernel threads that are waiting for resources
	`w`	The number of swapped out LWPs that are waiting for processing resources to finish
`memory`		Reports on usage of real memory and virtual memory:
	`swap`	Available swap space
	`free`	Size of the free list
`page`		Reports on page faults and paging activity, in units per second:
	`re`	Pages reclaimed
	`mf`	Minor faults and major faults
	`pi`	Kbytes paged in
	`po`	Kbytes paged out
	`fr`	Kbytes freed
	`de`	Anticipated memory that is needed by recently swapped-in processes
	`sr`	Pages scanned by the `page` daemon not currently in use. If `sr` does not equal zero, the `page` daemon has been running.
`disk`		Reports the number of disk operations per second, showing data on up to four disks
`faults`		Reports the trap/interrupt rates per second:
	`in`	Interrupts per second
	`sy`	System calls per second
	`cs`	CPU context switch rate
`cpu`		Reports on the use of CPU time:
	`us`	User time
	`sy`	System time
	`id`	Idle time

For a more detailed description of this command, see the vmstat(1M) man page.

How to Display Virtual Memory Statistics (`vmstat`)

Collect virtual memory statistics by using the vmstat command with a time interval in seconds.
```
$ vmstat n
```
where n is the interval in seconds between reports.

Example 11-1 Displaying Virtual Memory Statistics

The following example shows the vmstat display of statistics that were gathered at five-second intervals:

$ vmstat 5
kthr memory page disk faults cpu
 r b w swap free re mf pi po fr de sr dd f0 s1 -- in sy cs us sy id
 0 0 0 863160 365680 0 3 1 0 0 0 0 0 0 0 0 406 378 209 1 0 99

How to Display System Event Information (`vmstat -s`)

Run the vmstat -s command to show how many system events have taken place since the last time the system was booted.

$ vmstat -s
 0 swap ins
 0 swap outs
 0 pages swapped in
 0 pages swapped out
 522586 total address trans. faults taken
 17006 page ins
 25 page outs
 23361 pages paged in
 28 pages paged out
 45594 total reclaims
 45592 reclaims from free list
 0 micro (hat) faults
 522586 minor (as) faults
 16189 major faults
 98241 copy-on-write faults
 137280 zero fill page faults
 45052 pages examined by the clock daemon
 0 revolutions of the clock hand
 26 pages freed by the clock daemon
 2857 forks
 78 vforks
 1647 execs
 34673885 cpu context switches
 65943468 device interrupts
 711250 traps
 63957605 system calls
 3523925 total name lookups (cache hits 99%)
 92590 user cpu
 65952 system cpu
 16085832 idle cpu
 7450 wait cpu

How to Display Swapping Statistics (`vmstat -S`)

Run vmstat -S to show swapping statistics.
```
$ vmstat -S
kthr memory page disk faults cpu
 r b w swap free si so pi po fr de sr dd f0 s1 -- in sy cs us sy id
 0 0 0 862608 364792 0 0 1 0 0 0 0 0 0 0 0 406 394 213 1 0 99
```
The swapping statistics fields are described in the following list. For a description of the other fields, see Table 11-4.

si

Average number of LWPs that are swapped in per second

so

Number of whole processes that are swapped out
