【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 14424 Mar 13 2009 procflags
-r-xr-xr-x 1 bin bin 10898 Mar 13 2009 procldd
-r-xr-xr-x 1 bin bin 11602 Mar 13 2009 procmap
-r-xr-xr-x 1 bin bin 8158 Mar 13 2009 procrun
-r-xr-xr-x 1 bin bin 8938 Mar 13 2009 procsig
-r-xr-xr-x 1 bin bin 20524 Mar 18 2009 procstack
-r-xr-xr-x 1 bin bin 21774 Mar 18 2009 procstack64
-r-xr-xr-x 1 bin bin 8578 Mar 13 2009 procstop
-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

procflags
列印 /proc 跟蹤標誌、暫掛和掛起訊號，和指定程式中每個執行緒的其它 /proc 狀態資訊。顯示程式的跟蹤標誌。加“-r”選項可以列印暫存器內容。
$procflags 451098
451098 : acsql
data model = _LP64 flags = PR_FORK
/872965: flags = PR_ASLEEP | PR_NOREGS
procldd
列出程式裝入的動態庫，包括使用 dlopen() 顯式連線的共享物件。
$procldd 451098
