centos 6.5 monit監控inotifywait程序

最近2天，nagios總是報警，inotifywait程序為0

express_1這台主機有2個rsync腳本,express_1向express_2同步，開啟後，會有2個inotifywait程序。

每隔幾個小時就會挂掉，需要手動啟動一下。但是這樣太麻煩了，一晚上就發了十幾條nagios報警。

是以我就想用monit來監控inotifywait程序。

建立啟動腳本

vi /manage/express_monit.sh

#!/bin/bash

case "$1" in

start)

    echo "Starting express..."

    /manage/rsync/rsync_express.sh &

    sleep 1

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

    ;;

stop)

    echo "Stopping express..."

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

restart)

    echo

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

*)

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

esac

exit 0

設定權限

chmod 755 express_monit.sh

安裝monit，最好使用rpm安裝，使用編碼包編譯有問題

yum install -y monit

編輯配置檔案

vim /etc/monit.conf

修改檢查時間為3秒以及id檔案路徑和開啟日志

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

注釋倒數第3行

# set daemon mode timeout to 1 minute

#set daemon 60

進入配置目錄

cd /etc/monit.d/

添加express同步程序監控

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"

啟動monit

/etc/init.d/monit start

kill掉inotifywait程序

pkill inotifywait

觀察monit日志

tail -f /var/log/monit

檢視程序是否啟動

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