Monitoring Disk Utilization
There are many ways to monitor your network for performance. With proper monitoring, you can be notified immediately via email when metrics fall outside of predefined limits and alarms are triggered.
You will want to be sure that the system you use sends email notifications to a designated individual who can adjust the database if needed. We strongly recommend using an email distribution group so multiple people receive the notifications.
At a minimum, we strongly encourage you to actively monitor your systems including the percent disk utilization for free disk space. If a disk runs out of space your VM might stop running.
If you do not have a system for monitoring and sending alarms, one good option is Spiceworks https://www.spiceworks.com; a free SAAS based monitoring solution.
Spiceworks is very easy to setup. You start by creating an account, installing a monitor, and specifying what you want to monitor. Your basic monitoring can be setup and running in under 20 minutes.
