CentOS 6.5 monit Monitoring inotifywait process

Nagios always alarms in the last 2 days, and the inotifywait process is 0

Express_1 this host has 2 rsync scripts, express_1 to express_2 synchronization, after opening, there will be 2 inotifywait process.

It hangs every few hours and needs to be started manually. But it was too much trouble, and one night there were more than 10 nagios alarms.

So I wanted to use Monit to monitor the inotifywait process.

To create a startup script

vi/manage/express_monit.sh

#!/bin/bash

Case "$" in

Start

echo "Starting Express ..."

/manage/rsync/rsync_express.sh &

Sleep 1

Ps-aux | grep kuaidihelp_express | head-1 | awk ' {print $ ' >/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 $ ' >/var/run/express.pid

;;

*)

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

;;

Esac

Exit 0

Set permissions

chmod 755 express_monit.sh

Install Monit, preferably using RPM installation, using encoding package compilation problem

Yum Install-y Monit

Editing a configuration file

Vim/etc/monit.conf

Modify the check time to 3 seconds and ID file path and open log

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

Comment Bottom Line 3rd

# Set Daemon mode timeout to 1 minute

#set Daemon 60

Then start Monit

/etc/init.d/monit start

Go to configuration directory

cd/etc/monit.d/

Add Express Sync Process monitoring

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"

Start Monit

/etc/init.d/monit start

Kill off the inotifywait process

Pkill inotifywait

Observing Monit Logs

Tail-f/var/log/monit

[CST APR 10:41:07] Error: ' Express ' process is not running

[CST Apr 10:41:07] Info: ' Express ' trying to restart

[CST Apr 10:41:07] Info: ' Express ' Start:/manage/express_monit.sh

To see if a process starts

[Email protected] ~]# ps-aux | grep ino
