2.rpm -ivh sysstat-4.0.2-1.i386.rpm

編寫外掛程式:
以安裝完 sysstat 套件後,產生的 /usr/bin/sar 程式進行外掛程式的編寫,我寫了一個監測 CPU 的小程式,使用 bash 寫的,可以參考看看: [root @tsai cpu]# vi mrtg.cpu
---- 檔案開始 ----
#!/bin/bash
# 這個程式是用來偵測 CPU 的小外掛程式!
# 1. 開始使用 sar 來監測 CPU 的 user 及 System 負載率
cpuusr=`/usr/bin/sar -u 1 3 | grep Average | awk '{print $3}'`
cpusys=`/usr/bin/sar -u 1 3 | grep Average | awk '{print $5}'`
UPtime=`/usr/bin/uptime | awk '{print $3 " " $4 " " $5}'`
$4是什麼呢....可以解釋程式嗎.....
喜歡遼解比較好
# 2. 列出四個數據(前兩個為數字)
echo $cpuusr
echo $cpusys
echo $UPtime
echo redhat7.adsldns.org (這裡寫你的主機名稱)
---- 檔案結束 ----

[root @tsai cpu]# chmod 755 mrtg.cpu (設定成可執行)
[root @tsai cpu]# ./mrtg.cpu (測試看可執行否)
2.0
5.4 =========>只有一組數字何主機名稱
1 day, 22:30, =====>沒出來
redhat7.adsldns.org


開始設定 mrtg 參數檔:
我的參數檔有點像這樣: [root @tsai cpu]# vi mrtg.cfg.cpu =====不知如何建造(找不到)我cpu目錄內只有mrtg.cpu*檔
---- 檔案開始 ----
### Global Config Options

考network+ 要注意什麼呢
像多重處理是什麼我不知
煩請大大指導一下
