Hi Pranay,
Can you check agent-controller connectivity?
If it is fine,share agent.log file generated at location /home/ec2-user/apache-tomcat-7.0.82/webapps/appagent/ver4.5.9.25648/logs/<nodename>

Hi Santosh,
Please check https://docs.appdynamics.com/display/PRO45/Standalone+Machine+Agent+Requirements+and+Supported+Environments.
And try to install machine agent with version 4.5.7.
