How to Configure Low Disk Space Alerts by Percentage in ControlUp for Devices

In ControlUp for Devices (CU4D), setting up an alert to notify an administrator when any device’s OS disk free space drops below a certain threshold can be configured through the Events > Alert Rules section. To create an alert for low disk space, a user needs to define the appropriate category, metric, condition, and value that represent the target threshold.

The recommended approach is to use an alert rule that monitors the free space on the OS disk. While the initial example provided in the community discussion suggested a value-based threshold (e.g., a specific number of gigabytes free), it is also possible to configure an alert based on a percentage of free disk space. This is important for flexibility as percentages provide a more relative and scalable measure across devices with different disk sizes.

To implement this, the alert should be defined in the category related to storage or disk metrics. The metric to monitor would be the percentage of free space available on the OS disk. The condition would then be set to trigger when this percentage falls below a certain value (such as 10%). Once the alert triggers, it can be configured to send an email notification to administrators. Furthermore, ControlUp’s integration with script actions can automate responses to these alerts, such as running a system disk cleanup or presenting a user prompt to clean up space.

For detailed steps and additional options, users are encouraged to refer to the official ControlUp documentation on alert rules and script actions, as well as the ControlUp Knowledge Base and Academy resources at https://docs.controlup.com and https://cuacademy.controlup.com. These resources provide comprehensive guidance on setting conditions, selecting metrics, and automating remediation workflows based on alerts.

I would like to setup an event to trigger an email to the admin when any device’s OS disk is less than 10% free space.
What category, metric, condition and value will achieve this result?

assistance is appreciated. thanks so much for your help!

Hello James, here is an example you can use to setup the CU4D alert for low disk space.

Then you can tie this into the new script actions we have to run disk cleanup (system) or run user prompt (user).

Thanks Clint! this is helpful from a explicit value perspective. I’m just curious if there’s a way to do this based on a % perspective rather than a # of GB perspective.

I will try this out! thanks again!
