Just today, a new task came in where I will need to make a correction for a wrong setup alarm to monitor available disk space for EBS mount on Amazon Linux Instance.

My Situation:

Kindly note that in my situation and environment, CW Agent has been previously setup with metric name etc, reason why I would like to reinstall is due to “disk_used” metric cannot be found under CW Agent metric.

Download and Install
