AIX常用命令之查看cpu/memory/swap/network/disk信息
一.查看CPU
--物理cpu数 1.prtconf Processor Type: PowerPC_POWER5 Number Of Processors: 2 Processor Clock Speed: 2097 MHz CPU Type: 64-bit 2.lsdev -bash-3.00$ lsdev -Cc processor proc0 Available 00-00 Processor proc2 Available 00-02 Processor --逻辑cpu数 3.bindprocessor -bash-3.00$ bindprocessor -q The available processors are: 0 1 2 3 4.vmstat -bash-3.00$ vmstat System configuration: lcpu=4 mem=1904MB kthr memory page faults cpu ----- ----------- ------------------------ ------------ ----------- r b avm fre re pi po fr sr cy in sy cs us sy id wa 1 1 386273 51470 0 0 0 0 1 0 120 5221 937 1 2 97 1 5.smtctl 因为无权限执行,没有测试
二.查看内存
1.lsattr -bash-3.00$ lsdev -Cc memory L2cache0 Available L2 Cache mem0 Available Memory -bash-3.00$ lsattr -El L2cache0 size 1920 Size of L2 cache in Kbytes False -bash-3.00$ lsattr -El mem0 goodsize 1904 Amount of usable physical memory in Mbytes False size 1904 Total amount of physical memory in Mbytes False 2.prtconf -bash-3.00$ prtconf|grep Memory|grep -v + Memory Size: 1904 MB Good Memory Size: 1904 MB 3.vmstat -bash-3.00$ vmstat System configuration: lcpu=4 mem=1904MB kthr memory page faults cpu ----- ----------- ------------------------ ------------ ----------- r b avm fre re pi po fr sr cy in sy cs us sy id wa 1 1 387550 50188 0 0 0 0 1 0 120 5221 937 1 2 97 1 4.topas MEMORY Real,MB 1904 % Comp 76 % Noncomp 13 % Client 13

4.主要参数说明
-d:指定要监控的磁盘数。如果屏幕显示的区域足够大的话,这也是磁盘可显示的最大数。当这个数值超出实际安装的磁盘数,仅仅监控并显示安装磁盘的信息,默认为20.
-i:设置监控时间的间隔(秒),默认为2秒。
-n:设置被监控的网络接口数。这也是在屏幕上显示的最大网络接口数,当这个值超出了实际安装的网络接口数,仅仅监控并显示安装的网络接口信息。参数缺省值为20,如果这个值设为0,将没有网络信息被监控。
-p:指定被监控的进程数。这也是在屏幕上显示的最大进程数。缺省值为20,如果这个值为0,没见进程信息被监控。得到的这些进程信息是topas的主要开销。如果进程信息不需要,通常使用这个参数指定那些不想要的进程信息。
-w:指明被监控的WLM类的值。这也是在屏幕上显示的最大WLM值,当这个值超出了实际安装的WLM数,仅仅显示那些安装的WLM类的信息,缺省值为20,如果这个值为0,将没有信息显示。
-c:指明被监控的CPU数。这也是在屏幕上显示的最大CPU值,当这个值超出了实际安装的CPU数,仅仅显示那些安装的CPU的信息,缺省值为20,如果这个值为0,将没有信息显示。
-P:显示整个全屏进程显示。显示一系列最繁忙的进程,类似于默认显示的一部分,每个进程仅仅显示几列,可以通过任何列排序。
-W:显示全屏WLM(负载管理器)类。顶部显示一系列WLM类,类似于WLM类的一部分显示。
其实topas命令等同于:topas -d20 -i2 -n20 -p20 -w20 -c20
5.一些子命令说明
a 这个键显示所有被监控的(CPU,network,disk,WLM,process)不同部分。
c 这个键在累积报告和最忙的CPU之间进行切换。
d 这个键在最忙的磁盘和系统总的磁盘活动之间进行切换。
h 显示帮助信息。
n 这个键在最忙的接口和系统总的网络活动之间进行切换。
w 这个键在WLM类的开关之间切换。
p 这个键进程的开关之间切换。
P 这个键用全屏进程显示替换默认的显示。
W 这个键用全屏WLM类显示替换默认显示。
f 移动光标到一个WLM类上,这个键可以在WLM屏幕底端显示一系列进程情况。
q 退出程序。
r 更新显示。
6.topas内容说明
6.1)反映CPU使用率和工作状况
User%:进程所执行的用户态的状态占用的CPU百分比;
Kern%:进程所执行的内核态所占用CPU百分比;
Wait%:显示等待IO操作所占用的CPU百分比;
Idel%:显示CPU空闲的百分比。
6.2)反映网络使用率的状况

I-Pack:在监控期间每秒钟接收到的数据包数;
O-Pack:在监控期间每秒钟发送的数据包数;
KB-In:在监控期间每秒钟接收到的字节数(以K为单位);
KB-Out:在监控期间每秒钟发送的字节数(以K为单位)。
6.3)反映磁盘使用率的状况
Disk:物理磁盘的名称;
Busy%:磁盘繁忙的百分比,即磁盘能满足的最大IOPS(每秒IO操作数)和当前IO数量的比率
KBPS:在监控期间每秒钟读写的字节数(以K为单位);
TPS:每秒钟物理磁盘的数据传输量。一次传输指的是一次I/O请求;
KB-Read:每秒钟从物理磁盘读出的K字节数;
KB-Write:每秒钟向物理磁盘写入的K字节数。
6.4)反映进程的状况
NAME:可执行程序的名称;
Process ID:进程的ID号;
%CPU Utilization:进程的CPU平均使用率,这个值指的是进程在生命周期中的平均使用率;
Paging Space Used:分配给进程的分页空间大小;
Process Owner:拥有这个进程的用户名;
Workload Management(WLM)Class:进程属于哪个WLM class。
6.5)EVENTS/QUEUES 状况
Cswitch:在监控期间每秒钟上下文转换的次数;
Syscall:在监控期间每秒钟运行系统呼叫的总次数;
Reads:在监控期间每秒钟运行读系统呼叫的次数;
Writes:在监控期间每秒钟运行写系统呼叫的次数;
