shell腳本監控cpu/內存使用率 轉

該腳本檢測cpu和內存的使用情況,只需要調整memorySetting、cpuSetting、userEmail要發郵件報警的email地址即可
如果沒有配置發郵件參數的哥們,已配置了的,直接飛到代碼區:
1.vim /etc/mail.rc
2.找到以下內容
set from=[e-mail] #來自什么
set smtp=smtp.exmail.qq.com #根據您的郵箱發件服務器填寫,我這位是TX的企業郵箱
set smtp-auth-user=[e-mail] #郵箱用戶名
set smtp-auth-password=您的密碼 #注意是發郵件密碼,有的郵箱服務商登陸密碼和發件密碼不一樣的哦
set smtp-auth=login
**配置完成后可以直接echo ‘test content’ |mail -s ‘test title’ [e-mail]
如果收到郵件,說明您郵件配置是ok的,否則就是有見沒配置好哦,重新檢查用戶名密碼,smtp有沒有填錯!!!**
如果您覺得有用的話直接搬走就行了,不用聯系我!!!
