【shell】通过shell编写ping包及arp的监控并发送短信

1     #!/bin/bash
 2     NOW="`date +%Y%m%d-%H:%M:%S`"
 3     PHONES=15134567893
 4     IP=10.100.8.78
 5     GATEWAY=10.100.30.1
 6     #ping失误的短信内容
 7     content1="host is failed"
 8     #arp主机网关失误的短信内容
 9     content2="GW is failed"
10     #ping日志路径
11     LogFile="/tmp/ping`date "+%Y%m%d-%H-%M-%S"`.log"
12     #ping对方主机100个包并将结果输出到日志
13     ping -c100 $IP &> $LogFile
14     #用if，else语句判断是否ping通，
15     if [ "$?" == "0" ];
16         then
17             echo "$NOW $IP is ok">> $LogFile
18     else
19             echo "$NOW $IP is down">> $LogFile &/usr/bin/curl -d "phones=$PHONES&content= $NOW $IP $content" "content-type: application/x-www-form-urlencoded;charset=UTF-8" "http://短信网关:8080"
20     fi
21     #分隔符
22     echo "================================" >> $LogFile
23     #arp自己网关
24     arp $GATEWAY &>>$LogFile
25     num=$(cat $LogFile |grep eth0|wc -l)
26         if [ "$num" == "0" ];
27             then
28               echo "$NOW $GATEWAY is down">> $LogFile &/usr/bin/curl -d "phones=$PHONES&content= $NOW $GATEWAY $content1" "content-type: application/x-www-form-urlencoded;charset=UTF-8" "http://短信网关:8080"
