First Login to your Ec2 instance

====yum install perl-Switch perl-DateTime perl-Sys-Syslog perl-LWP-Protocol-https perl-Digest-SHA
====>curl https://aws-cloudwatch.s3.amazonaws.com/downloads/CloudWatchMonitoringScripts-1.2.2.zip -O
====>ls -ltr
====>unzip CloudWatchMonitoringScripts-1.2.2.zip && \
rm CloudWatchMonitoringScripts-1.2.2.zip && \
cd aws-scripts-mon
====>cp awscreds.template awscreds.conf

Then go to aws console and give IAM roles cloudwach full access to ec2 instance
Then create aws cridentials(acces key, secreat key)
====>AWSAccessKeyId=Access Key
====>AWSSecretKey=Secreat key

====>./mon-put-instance-data.pl --mem-util --verify --verbose
====>./mon-put-instance-data.pl --mem-used-incl-cache-buff --mem-util --mem-used --mem-avail
====>crontab -e
(enter it will take to vi mode in the vi mode -->*/5 * * * * ~/aws-scripts-mon/mon-put-instance-data.pl --mem-used-incl-cache-buff --mem-util --disk-space-util --disk-path=/ --from-cron)
====>./mon-put-instance-data.pl --mem-util --mem-used --mem-avail --auto-scaling=only
====>./mon-put-instance-data.pl --mem-util --mem-used --mem-avail --aggregated=only
====>./mon-get-instance-stats.pl --recent-hours=12

Then you will get results Like this
