目前网上关于网站存活监控的脚本很多,本站也放过几个,今天给大家再来个ping+curl监控网站并发邮件报警的脚本,我觉得这个脚本的思路很不错,大家有兴趣的可以下来看看.
脚本内容:
cat /root/soft_shell/check-www.sh
|
06 |
list=(blog.slogra.com slogra.com) |
|
08 |
date=$(date -d "today" +"%Y-%m-%d-%H:%M:%S") |
|
13 |
if ping -c1 ${list[$i]} >/dev/null |
|
15 |
echo $date:服务器${list[$i]}能ping通. |
|
17 |
if curl -m 10 ${list[$i]} > /dev/null |
|
19 |
echo $date:服务器${list[$i]} ping不通,能打开网页. |
|
21 |
echo "您好,据系统监测服务器${list[$i]}不能访问且ping不通,请及时处理!故障发生时间：$date"|mail -s "服务器${list[$i]}不能连接! 故障发生时间：$date"$mail |
|
23 |
date=$(date -d "today" +"%Y-%m-%d-%H:%M:%S") |
|
24 |
ping -c1 ${list[$i]} >/dev/null && echo "恭喜！服务器${list[$i]}已恢复正常,恢复时间：$date"|mail -s "服务器${list[$i]}已恢复正常! 恢复时间：$date" $mail |
放入后台运行:
nohup sh /path/file.sh & #把脚本放到后台运行,程序自己会60秒检查一次网站.
开机自启动:
echo "nohup sh /root/soft_shell/check-www.sh & " >> /etc/rc.local
下面还有个类似的脚本,但他控制了发邮件的频率:
cat /root/soft_shell/check-web.sh
|
03 |
SITES=("http://blog.slogra.com" "http://slogra.com")# 要监控的网站 |
|
04 |
NOTICE_EMAIL='me@example.com' # 管理员电邮 |
|
05 |
MAXLOADTIME=10 # 访问超时时间设置 |
|
06 |
REMARKFILE='/tmp/monitor_load.remark' # 记录时否发送过通知电邮,如发送过则一小时内不再发送 |
|
08 |
EXPIRE=3600 # 每次发送电邮的间隔秒数 |
|
11 |
if [ -f "$REMARKFILE" ] && [ -s "$REMARKFILE" ]; then |
|
12 |
REMARK=$(cat $REMARKFILE) |
|
15 |
if [ $(( $NOW - $REMARK )) -gt "$EXPIRE" ]; then |
|
24 |
for site in ${SITES[*]}; do |
|
26 |
printf "start to load ${site}\n" |
|
27 |
site_load_time=$(curl -o /dev/null -s -w "time_connect: %{time_connect}\ntime_starttransfer: %{time_starttransfer}\ntime_total: %{time_total}" "${site}") |
|
28 |
site_access=$(curl -o /dev/null -s -w %{http_code} "${site}") |
|
29 |
time_total=${site_load_time##*:} |
|
31 |
printf "$(date '+%Y-%m-%d %H:%M:%S')\n" |
|
32 |
printf "site load time\n${site_load_time}\n" |
|
33 |
printf "site access:${site_access}\n\n" |
|
36 |
if [ "$REMARK" = "" ]; then |
|
38 |
if [ "$time_total" = "0.000" ] || [ "$site_access" != "200" ]; then |
|
39 |
echo "Subject: ${site} can access $(date +%Y-%m-%d' '%H:%M:%S)" | sendmail ${NOTICE_EMAIL} |
|
43 |
if [ "${time_total%%.*}" -ge ${MAXLOADTIME} ]; then |
|
44 |
echo "Subject: ${site} load time total:${time_total} $(date +%Y-%m-%d' '%H:%M:%S)" | sendmail ${NOTICE_EMAIL} |
|
53 |
if [ "$ISSEND" = "1" ]; then |
|
54 |
echo "$(date +%s)" > $REMARKFILE |
ps:
1.检查网站返回的http_code是否等于200,如不是200视为异常.
2.检查网站的访问时间,超过MAXLOADTIME（10秒）视为异常.
3.发送通知邮件后,在/tmp/monitor_load.remark记录发送时间,在一小时内不重复发送,如一小时后则清空/tmp/monitor_load.remark.
