查看cpu 和内存使用率
环境：unix AIX Version 5
怎样查看cpu的使用率和内存使用率？
我在网上查看了用top命令，top命令好像不好使

------解决方案--------------------
sysstat or top 


free -m 


你可以先man top
看看有没有相关帮助？
如果有的话，说明你的top命令是好用的！

------解决方案--------------------
不是把， 差不多吧！
top :
top - 19:19:32 up 39 min, 1 user, load average: 0.36, 0.39, 0.37
Tasks: 120 total, 1 running, 118 sleeping, 0 stopped, 1 zombie
Cpu(s): 5.2%us, 2.7%sy, 0.0%ni, 92.0%id, 0.0%wa, 0.2%hi, 0.0%si, 0.0%st
Mem: 969328k total, 790264k used, 179064k free, 52788k buffers
Swap: 2112508k total, 0k used, 2112508k free, 305652k cached

free :
total used free shared buffers cached
Mem: 969328 790516 178812 0 52736 305600
-/+ buffers/cache: 432180 537148
Swap: 2112508 0 2112508

vmstat :

procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----
 r b swpd free buff cache si so bi bo in cs us sy id wa
 2 0 0 178312 52804 305700 0 0 72 18 85 1119 13 4 82 1

感觉top还好一点^_^

"us sy id wa" is useful to you
us: time spend running non-kenel code
sy: time spend running kenel code(system time)
id: idle time
wa: time waiting for IO
...

you can "man vmstat" to get them

"top","vmstat" is enough for you
