AIX使用/usr/bin/procXXX工具获取进程信息

AIX进程监控工具

  AIX平台有一组功能强大的进程监控工具，利用它们可以进行进程监控、定位问题。不使用这些工具，直接从/proc/procssId目录下也可以获得这些信息。
e.g.

/proc/177022>ls -lt
total
16
-rw-------    1 root     system            0 Feb 22 16:55
as
-r--------    1 root     system          128 Feb 22 16:55
cred
--w-------    1 root     system            0 Feb 22 16:55
ctl
dr-x------    1 root     system            0 Feb 22 16:55
fd
dr-xr-xr-x    1 root     system            0 Feb 22 16:55
lwp
-r--------    1 root     system            0 Feb 22 16:55
map
dr-x------    1 root     system            0 Feb 22 16:55
object
-r--r--r--    1 root     system          448 Feb 22 16:55
psinfo
-r--------    1 root     system        12288 Feb 22 16:55
sigact
-r--------    1 root     system         1520 Feb 22 16:55
status
-r--r--r--    1 root     system            0 Feb 22 16:55
sysent
lr-x------   36 root     system            0 Feb 22 13:35 cwd

一、存放路径

   这些工具存放在/usr/bin目录下，如下所示：

$which procstack

/usr/bin/procstack

二、工具列表

这些工具名称为procXXXX。分别有：

$ls *proc* /usr/bin/

-r-xr-xr-x    1 bin      bin            8754 Mar 13 2009  procwdx
三、用法示例

下面将一一认识一下这些命令。
proccred

 显示进程所属的有效的、真实的、保留的用户ID和组ID。什么叫“有效的、真实的、保留的”？尚不大清楚。

$proccred 451098

451098: e/r/suid=205  e/r/sgid=1

procfiles
显示进程打开的文件描述符信息。该命令对于监控程序是否有句柄泄露非常有用。

$procfiles 451098

451098 : acsql

procflags

 打印 /proc 跟踪标志、暂挂和挂起信号，和指定进程中每个线程的其它 /proc 状态信息。显示进程的跟踪标志。加“-r”选项可以打印寄存器内容。

$procflags 451098

451098 : acsql 

data model = _LP64 flags = PR_FORK 

/872965: flags = PR_ASLEEP | PR_NOREGS  

procldd

列出进程装入的动态库，包括使用 dlopen() 显式连接的共享对象。
