【AIX】AIX程式監控工具

AIX平臺有一組功能強大的程式監控工具，利用它們可以進行程式監控、定位問題。不使用這些工具，直接從/proc/procssId目錄下也可以獲得這些資訊。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、存放路徑

    這些工具存放在/usr/bin目錄下，如下所示：

$which procstack

/usr/bin/procstack

二、工具列表

    這些工具名稱為procXXXX。分別有：

$ls *proc* /usr/bin/

-r-xr-xr-x    1 bin      bin            8282 Mar 13 2009  proccred

-r-xr-xr-x    1 bin      bin           17340 Mar 13 2009  procfiles

-r-xr-xr-x    1 bin      bin           20022 Mar 13 2009  proctree

-r-xr-xr-x    1 bin      bin           13216 Mar 13 2009  procwait

-r-xr-xr-x    1 bin      bin            8754 Mar 13 2009  procwdx

三、用法示例

下面將一一認識一下這些命令。

proccred

    顯示程式所屬的有效的、真實的、保留的使用者ID和組ID。什麼叫“有效的、真實的、保留的”？尚不大清楚。

$proccred 451098

451098: e/r/suid=205  e/r/sgid=1

procfiles

顯示程式開啟的檔案描述符資訊。該命令對於監控程式是否有控制程式碼洩露非常有用。

$procfiles 451098

451098 : acsql
