Tomcat Monitor Script with Restarting

Here is my script.

#!/bin/sh

if netstat -tln | grep 8443  && ps -ef | grep tomcat | grep java

then
    date
    echo "Tomcat Running"

else
    date
    echo "Tomcat Stopped"
    source /root/.bash_profile
    date
    /app/apache-tomcat-8.0.28/bin/startup.sh >> /root/restarttomcat.log 2>&1
    echo "Tomcat Restarted"
    mailx -s "Tomcat not running" xxxx@gmail.com < /root/tomcatwordings
fi

"tomcatwordings" is file for the email contents. 


Here is the crontab
*/2 * * * * /root/checktomcat.sh >> /root/checktomcat.log 2>&1

"checktomcat.log" is the log for the monitoring script
"checktomcat.sh" is the script file with the above content.
