这是基础知识。 但我不确定这些是否算“清晰且简单”。

ps(1)

对于进程级视图:

$ ps -opid,vsz,rss,osz,args
  PID  VSZ  RSS   SZ COMMAND
 1831 1776 1008  222 ps -opid,vsz,rss,osz,args
 1782 3464 2504  433 -bash
$

vsz/VSZ:总虚拟进程大小(kb)

rss/RSS:驻留集大小(kb,可能不准确(! ),参见 man)

osz/SZ:内存中的总大小(页)

要从页计算字节大小:

$ sz_pages=$(ps -o osz -p $pid | grep -v SZ )
$ sz_bytes=$(( $sz_pages * $(pagesize) ))
$ sz_mbytes=$(( $sz_bytes / ( 1024 * 1024 ) ))
$ echo "$pid OSZ=$sz_mbytes MB"

vmstat(1M)

$ vmstat 5 5 
 kthr      memory            page            disk          faults      cpu
 r b w   swap  free  re  mf pi po fr de sr rm s3 -- --   in   sy   cs us sy id
 0 0 0 535832 219880  1   2  0  0  0  0  0 -0  0  0  0  402   19   97  0  1 99

^C

prstat(1M )

   PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP       
  1852 martin   4840K 3600K cpu0    59    0   0:00:00 0.3% prstat/1
  1780 martin   9384K 2920K sleep   59    0   0:00:00 0.0% sshd/1
  ...

swap(1)

“长列表”和“摘要”模式:

$ swap -l
swapfile             dev  swaplo blocks   free
/dev/zvol/dsk/rpool/swap 256,1      16 1048560 1048560
$ swap -s 
total: 42352k bytes allocated + 20192k reserved = 62544k used, 607672k available
$

top(1)

Sun 的 Solaris 配套 CD 上提供了旧版本 (3.51),并声明这是“社区(不支持 Sun)”。
sunfreeware.com 或blastwave.org 提供了更多最新的二进制软件包。

sar 到底出了什么问题? :)

Here are the basics. I'm not sure that any of these count as "clear and simple" though.

ps(1)

For process-level view:

$ ps -opid,vsz,rss,osz,args
  PID  VSZ  RSS   SZ COMMAND
 1831 1776 1008  222 ps -opid,vsz,rss,osz,args
 1782 3464 2504  433 -bash
$

vsz/VSZ: total virtual process size (kb)

rss/RSS: resident set size (kb, may be inaccurate(!), see man)

osz/SZ: total size in memory (pages)

To compute byte size from pages:

$ sz_pages=$(ps -o osz -p $pid | grep -v SZ )
$ sz_bytes=$(( $sz_pages * $(pagesize) ))
$ sz_mbytes=$(( $sz_bytes / ( 1024 * 1024 ) ))
$ echo "$pid OSZ=$sz_mbytes MB"

vmstat(1M)

$ vmstat 5 5 
 kthr      memory            page            disk          faults      cpu
 r b w   swap  free  re  mf pi po fr de sr rm s3 -- --   in   sy   cs us sy id

^C

prstat(1M)

   PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP

  1780 martin   9384K 2920K sleep   59    0   0:00:00 0.0% sshd/1
  ...

swap(1)

"Long listing" and "summary" modes:

$ swap -l
swapfile             dev  swaplo blocks   free
/dev/zvol/dsk/rpool/swap 256,1      16 1048560 1048560
$ swap -s 
total: 42352k bytes allocated + 20192k reserved = 62544k used, 607672k available
$

An older version (3.51) is available on the Solaris companion CD from Sun, with the disclaimer that this is "Community (not Sun) supported".
More recent binary packages available from sunfreeware.com or blastwave.org.

“top”通常在 Solaris 上可用。

如果没有,则恢复到大多数 UNIX 系统上可用的“vmstat”。

它应该看起来像这样(来自 AIX 机器),

vmstat

System configuration: lcpu=4 mem=12288MB ent=2.00

kthr    memory              page              faults              cpu
----- ----------- ------------------------ ------------ -----------------------
 r  b   avm   fre  re  pi  po  fr   sr  cy  in   sy  cs us sy id wa    pc    ec
 2  1 1614644 585722   0   0   1  22  104   0 808 29047 2767 12  8 77  3  0.45  22.3

列“avm”和“fre”告诉您总内存和可用内存。

“man vmstat”应该可以让你了解血淋淋的细节。

"top" is usually available on Solaris.

If not then revert to "vmstat" which is available on most UNIX system.

It should look something like this (from an AIX box)

vmstat

System configuration: lcpu=4 mem=12288MB ent=2.00

kthr    memory              page              faults              cpu
----- ----------- ------------------------ ------------ -----------------------
 r  b   avm   fre  re  pi  po  fr   sr  cy  in   sy  cs us sy id wa    pc    ec
 2  1 1614644 585722   0   0   1  22  104   0 808 29047 2767 12  8 77  3  0.45  22.3

the colums "avm" and "fre" tell you the total memory and free memery.

a "man vmstat" should get you the gory details.

Top 可以从源代码编译或从 sunfreeware.com 下载。 正如之前发布的,vmstat 可用(我相信它在核心安装中?)。

Top can be compiled from sources or downloaded from sunfreeware.com. As previously posted, vmstat is available (I believe it's in the core install?).

命令 free 很好。 需要一段时间来理解“+/-缓冲区/缓存”,但其想法是,在评估“空闲”时,缓存和缓冲区实际上并不重要,因为它可以立即转储。 因此,要查看您有多少可用(和已用)内存,您需要删除缓存/缓冲区的使用 - 这对您来说很方便。

The command free is nice. Takes a short while to understand the "+/- buffers/cache", but the idea is that cache and buffers doesn't really count when evaluating "free", as it can be dumped right away. Therefore, to see how much free (and used) memory you have, you need to remove the cache/buffer usage - which is conveniently done for you.
