If the disk utilization is high for a platform or a collector, vRealize Network Insight triggers an alert to warn the user to manage the disk space. vRealize Network Insight also provides a recommendation of how much more disk space is to be added.

To view the alerts related to disk utilization, navigate to the platform dashboard or the collector dashboard. You can also view these alerts in the corresponding collector or the platform section in the Infrastructure and Support > Infrastructure and Updates page.
