    text
    copied!<p>I am writing to get some help regarding starting my java programs via Monit. I have written a start script program.sh. The monit code and the scipt code is given with this posting.</p> <p>The issue is that I am not able the start and stop the program using the the script file executed via monit. I can monitor the process if I start it using the terminal but I can't start/stop it with monit. The log from monit says "Failed to start"</p> <p>However, I can start and stop programs like ssh easliy from monit. The monit runs under sudo and I am running the scripts from an account with administrative privileges. It will very helpful if someone helps me figure this out Thanks</p> <p>monitrc file</p> <pre><code>#++++++++++#+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #Monit settings set daemon 10 with start delay 2 # check services at 2-minute intervals set logfile syslog facility log_daemon set logfile /var/log/monit.log set idfile /var/lib/monit/id set statefile /var/lib/monit/state #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # Mail Server set mailserver smtp.gmail.com port 587 username "monit.abc123@gmail.com" password "password" using tlsv1 with timeout 30 seconds set eventqueue basedir /var/lib/monit/events # set the base directory where events will be stored slots 100 # optionally limit the queue size set alert abc123@gmail.com # receive all alerts set alert abc123@gmail.com only on { timeout } # receive just service- # # timeout alert #set alert foo@bar { nonexist, timeout, resource, icmp, connection } #set alert security@bar on { checksum, permission, uid, gid } # setup the email for the SMS thing over here....................... #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ set httpd port 2813 and # use address localhost # only accept connection from localhost allow localhost # allow localhost to connect to the server and allow 0.0.0.0/0.0.0.0 allow admin:monit # require user 'admin' with password 'monit' # allow @monit # allow users of group 'monit' to connect (rw) # allow @users readonly # allow users of group 'users' to connect readonly #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ set mail-format { from: monit@$HOST subject: Monit Alert -- $EVENT $SERVICE message: $EVENT Service $SERVICE Date: $DATE Action: $ACTION Host: $HOST Description: $DESCRIPTION Your faithful employee, Monit } #+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #*********************************************************************************************** #Computer Resources check check system myhost.mydomain.tld if loadavg (1min) &gt; 4 for 5 cycles then alert if loadavg (5min) &gt; 2 for 5 cycles then alert if memory usage &gt; 75% for 3 cycles then alert if swap usage &gt; 25% for 5 cycles then alert if cpu usage (user) &gt; 70% for 5 cycles then alert if cpu usage (system) &gt; 70% for 5 cycles then alert if cpu usage (wait) &gt; 20% for 5 cycles then alert #*********************************************************************************************** ################################################################################################ #Monitoring SSH Service check process ssh123 with pidfile /var/run/sshd.pid start program = "/etc/init.d/ssh start" stop program = "/etc/init.d/ssh stop" if cpu &gt; 50% for 5 cycles then alert if totalmem &gt; 200 MB for 5 cycles then alert if children &gt; 2 then alert #if loadavg(5min) greater than 10 for 8 cycles then stop #if 5 restarts within 5 cycles then timeout ################################################################################################ #Monitoring Prorgam in Java check process javaprg with pidfile /home/user/Desktop/Binaries/javaprg.pid start program = "/home/user/Desktop/Binaries/javaprg.sh start" stop program = "/home/user/Desktop/Binaries/javaprg.sh stop" if cpu &gt; 50% for 5 cycles then alert if totalmem &gt; 1500 MB for 5 cycles then alert if children &gt; 2 then alert #if loadavg(5min) greater than 10 for 8 cycles then stop #if 5 restarts within 5 cycles then timeout </code></pre> <p>Start/Stop script</p> <pre><code>#!/bin/bash case $1 in start) echo $$ &gt; javaprg.pid; exec /usr/bin/java -jar javaprg.jar ;; stop) kill $(cat javaprg.pid); rm javaprg.pid ;; *) echo "usage: javaprg {start|stop}" ;; esac exit 0 </code></pre>
