This read-write object sets the percentage disk space utilization threshold that, once exceeded, triggers a cuspDiskSpaceThresholdAlert notification. An admin configures this value to control how proactively they are warned about disk space running low, balancing early warning against nuisance alerts. If the admin sets cuspDiskSpaceThresholdValue to 80 and cuspDiskSpaceUsed later crosses 80 percent of capacity, they would receive an alert prompting cleanup before the disk actually fills.
