Fix Recommendation

Configure the system to notify appropriate support staff immediately upon storage volume utilization reaching 75 percent.

MariaDB does not monitor storage, however, it is possible to monitor storage with a script.

##### Example Monitoring Script

#!/bin/bash

DATADIR=/var/lib/psql/mysql
CURRENT=$(df ${DATADIR?} | grep / | awk '{ print $5}' | sed 's/%//g')
THRESHOLD=75

if [ "$CURRENT" -gt "$THRESHOLD" ] ; then
mail -s 'Disk Space Alert' mail@support.com << EOF
The data directory volume is almost full. Used: $CURRENT
%EOF
fi

Schedule this script in cron to run around the clock.
