File system utilization report in mail

File system utilization report in mail

Issue :
Very often file systems are filled with application logs and other data,This space filling makes the server to panic for the servers which do not have proper monitoring in place.

Goal :
Deploy a  script to monitor the file systems usage with a defined threshold and to notify the support team and application team to clear the space.

Solution :
A script has been created to monitor the File System usage with a threshold of 85%, This script will run in cron every 30 minutes and send a mail to mentioned mail ID's if any of the File System is more than 85%

#!/bin/ksh
#disk_usage.sh - Monitor the disk usage and alert the support/applicaiton team
