centos 6.5 monit监控inotifywait进程

最近2天，nagios总是报警，inotifywait进程为0

express_1这台主机有2个rsync脚本,express_1向express_2同步，开启后，会有2个inotifywait进程。

每隔几个小时就会挂掉，需要手动启动一下。但是这样太麻烦了，一晚上就发了十几条nagios报警。

所以我就想用monit来监控inotifywait进程。

创建启动脚本

vi /manage/express_monit.sh

#!/bin/bash

case "$1" in

start)

    echo "Starting express..."

    /manage/rsync/rsync_express.sh &

    sleep 1

    ps -aux | grep kuaidihelp_express | head -1 | awk ‘{print $2}‘ > /var/run/express.pid

    ;;

stop)

    echo "Stopping express..."

    kill -9 `cat /var/run/express.pid`

    ;;

restart)

    echo "Stopping express..."

    kill -9 `cat /var/run/express.pid`

    sleep 1

    echo

    echo "Starting express..."

    /manage/rsync/rsync_express.sh &

    sleep 1

    ps -aux | grep kuaidihelp_express | head -1 | awk ‘{print $2}‘ > /var/run/express.pid

    ;;

*)

    echo "Usage: $prog {start|stop|restart}"

    ;;

esac

exit 0

设置权限

chmod 755 express_monit.sh

安装monit，最好使用rpm安装，使用编码包编译有问题

yum install -y monit

编辑配置文件

vim /etc/monit.conf

修改检查时间为3秒以及id文件路径和开启日志

set daemon  3        # check services at 2-minute intervals

# set logfile syslog facility log_daemon

set logfile /var/log/monit.log

 set idfile /var/.monit.id

 set statefile /var/.monit.state

注释倒数第3行

# set daemon mode timeout to 1 minute

#set daemon 60

然后启动monit

/etc/init.d/monit start

进入配置目录

cd /etc/monit.d/

添加express同步进程监控

vi express

check process express with pidfile /var/run/express.pid

   start program = "/manage/express_monit.sh start"

   stop program = "/manage/express_monit.sh stop"

启动monit

/etc/init.d/monit start

kill掉inotifywait进程

pkill inotifywait

观察monit日志

tail -f /var/log/monit

[CST Apr 20 10:41:07] error    : ‘express‘ process is not running

[CST Apr 20 10:41:07] info     : ‘express‘ trying to restart

[CST Apr 20 10:41:07] info     : ‘express‘ start: /manage/express_monit.sh

[CST Apr 20 10:41:12] info     : ‘express‘ process is running with pid 14139

查看进程是否启动

[root@iZ23vu75locZ ~]# ps -aux | grep ino

Warning: bad syntax, perhaps a bogus ‘-‘? See /usr/share/doc/procps-3.2.8/FAQ

root     14306  0.0  0.0   6344   776 ?        S    10:41   0:00 /usr/local/inotify/bin/inotifywait -mrq --timefmt %d/%m/%y %H:%M --format %T %w%f -e modify,delete,create,attrib /www/kuaidihelp_express/

root     17537  0.0  0.0 103252   864 pts/2    S+   10:47   0:00 grep ino

测试正常。
