之前有mrtg去監控apache process的執行數量，首先開啟apache server-status的功能，讓我們可以透過瀏覽器或是本機讀取http://localhost/server-status，或是在本機執行service httpd fullstatus都可以看到apache最新的狀態，不過這個狀態是很簡單的一種文字模式，要一直不斷讀取才可以一直看到最即時的。
為了要能像top一樣觀察，我找了apache-top的工具，希望可以找出吃資源的兇手，apache-top.py是單一的執行檔，只要系統內能夠用行python就能夠執行，下載回家之後記得chmod +x apache-top.py，之後就可以使用囉！
apache-top.py -u http://127.0.0.1/server-status
執行過後就像最上方的圖片一樣囉！

使用方式：
Usage: apache-top -u url
-u url Url where apache-status is located
Example: apache-top.py -u http://www.domain.com/server-status
可以依照不同欄位進行排序，我想C和I應該都會很實用。
Interactive keys:
q Exit
P Sort by PID
C Sort by CPU usage
S Sort by Seconds since beginning of most recent request
V Sort by VirtualHost
M Sort by Mopde of operation
R Sort by Request
I Sort by Ip
a Switch between show all processes and show only active processes (default)
r Reverse sort
