# Class CIM_VTLResourceUsage
extends CIM_StatisticalData

The CIM_VTLResourceUsage class provides the ability to track the current resource usage of the device in order to detect when the device resources are approaching their limits (and thus further device hardware is needed or some backups needs to be moved to another device). All these device resources need to be tracked at both the whole-device level but also at the virtual library level. Tracking resource usage at the library level is critical because the VLS can be partitioned into multiple logical libraries that use physically separate resources (e.g. different front-end FC ports, different storage pools) so if the device shows 50% full this could mean one library is 100% full and another library is 0% full. It contains data representing used capacity, compression ratios and deduplication ratios at VTL or VLS level.also support the ability to set resource thresholds so that alerts are generated when the device approaches a warning or critical resource threshold (to alert the user they may need to add hardware or reduce workload)
