開發nagios修改配置檔案平臺

科技小先鋒發表於2017-11-15

[背景]本文的宗旨，是為解決在後期Nagios新增監控物件而煩的管理員做的工具。當然，也是為我減輕工作，而開發的。雖然說，我們可以寫指令碼來解決，但如果是那種每天會新增一兩個IP來做監控，那麼我們是不是每天都要登入伺服器，修改配置檔案，再測試，重啟。感覺不是很方便，如果有一個web介面來操作，那視覺肯定又不一樣，與是我就想到了要開發這款工具，來為自己或者大家來解決現在的問題，可能會有人說，現在的這樣的圖形工具太多了，是的，我也測試了一款，但感覺不是很理想，把我原先的配置檔案全打亂了，而且在新增監控物件的時候，N多引數要填寫，那個煩啊!~今天，這款工具，只要平臺支援php，基本就可以使用了。喜不喜歡，在與能不能讓你的工作更方便，不過，我已經準備用它了。呼呼….

附上一款備份nagios配置檔案的指令碼

#!/usr/bin/env python
“`Backup config files  of nagios“`

import glob
import os 
import time
import shutil

nagios_path=”config file of nagios”
bak_path=”/backup/nagios/”
DATEFORMAT=”%Y%m%d”

class nagios(object):
        pass

def copy():
        cp_nagios = nagios()

        os.chdir(nagios_path) 
        filelist=glob.glob(`*.cfg`)
        datedir=time.strftime(DATEFORMAT,time.localtime())
        dirname=bak_path+datedir
        if not os.path.exists(dirname):
                os.mkdir(dirname)
                for file in filelist:
                        sfile=nagios_path+file
                        shutil.copy(sfile,dirname)

if __name__ == `__main__`:

        copy()
