背景及思路：
五一小長假之前，公司要求我做一次服務器巡檢。
1、寫了一個簡單的腳本獲取服務器的各種基礎信息：cpu，內存，swap分區使用情況，磁盤，網卡信息種種，具體見腳本，將這些信息追加到一個文件中，然後在監控機上做一次彙總，彙總方式就不詳談，我用的是for循環ssh追加
2、然後利用python的xlsxwriter模塊生成excel
3、最後利用python髮帶附件爲excel的郵件到指定郵箱
獲取服務器信息部分腳本：
#取所需要的內網IP
Int_ip=`ifconfig|awk '/inet addr/ {gsub(/:/," ");print $3}'|egrep "^192.168.18"|head -1`
#取除該內網ip以及127.0.0.1之外的所有ip
Out_ip_list=`ifconfig|awk '/inet addr/ {gsub(/:/," ");print $3}'|grep -v $Int_ip|grep -v 127.0.0.1`
#取內存總值，單位爲G，四捨五入
Memory=`free -m|awk '/Mem/ {printf ("%.f\n",$2/1024)}'`
#取內存fr
ee值，從系統角度看，取的是第一行的free
Memory_free=`free -m|awk '/Mem/ {printf "%.f\n",$4/1024}'`
#取CPU核數
Cpu_num=`grep processor /proc/cpuinfo|wc -l`
#取服務器運行時間
Uptime=`uptime|awk '{print $3}'`
#取最近15分的負載
Load=`uptime|awk '{print $12}'`
#取磁盤大於80%的磁盤目錄
Disk=`df -h|awk '{a=+$(NF-1);if(a>=80)print $NF}'`
#swap分區總值，單位爲G，四捨五入
Swap=`free -m|awk '/Swap/ {printf ("%.f\n",$2/1024)}'`
#swap分區
Swap_free=`free -m|awk '/Swap/ {printf "%.f\n",$4/1024}'`
生成excel

1、設置 Excel 樣式
2、將數據寫入到 Excel 中

# 生成 Excel 文件

# 建立工作表，表名默認
worksheet = work.add_worksheet()
# 設置字體加粗、字體大小

效果在上面
ps:上傳文件非法，需要腳本的留個郵箱吧，不好意思
