How to Monitor Free Disk Space



Monitoring free disk space is critical to maintaining a reliable computing infrastructure. IsItUp includes a Disk Space Monitor to assist system administrators and others to manage disk space. There is also a CPU, Memory, and Event Log monitor to provide a comprehensive solution to server health monitoring. Since disk space can grow unexpectedly, it is necessary to monitor space on:
  • Operating System drives
  • Application drives for Web Servers, DB Servers, Mail servers, etc
  • User data drives
  • Other drives


to maintain system health. Administrators need to be alerted to low disk space so that appropriate action can be taken. Without disk space monitoring, it is impossible to avoid server slow down, critical data loss and user dissatisfaction. The disk space monitor can check both local and remote disk space and alert you when thresholds are reached. Disk space thresholds can be set as an amount of space remaining or by percent of total disk size.

How to set up a Disk Space Monitor


1. On the home tab, select the Add Monitor button and then the Disk Space Monitor. This will launch the Disk Space Monitor wizard.


2. Enter a device name and select the desired group. Then enter the drive letter you want to monitor and the minimum amount of space that will trigger any configured alerts. You may select a specific amount of space remaining in kilobytes, megabytes, gigabytes, or as a percent of the whole disk. Any drive letter that is available on the PC including mapped drives may be used. This is helpful when the disk to be monitored is on a remote machine such as a SAN or NAS or any other remote storage device that does not support WMI but still allows you to map a drive letter. After you enter the drive letter and the threshold, enter remote log on information if the drive is on a different machine and is not mapped locally.



3. Alternatively, you can select the browse button to select from a list. If the drive is on a different machine, you must enter the remote information before clicking the Browse button. The following screen will be displayed:




4. Select the drive you wish to monitor and click OK.

5. Finally, either click “Next” to configure the poll Frequency and Dependencies, Maintenance Schedules, Alerts and Service Restarts or click “Finish” to immediately begin monitoring.
