Description: Number of used up licenses of the type celPoolLicenseType. Each time a license is used up by the appropriate entity (physical or otherwise), this number is incremented. Similarly, when a license is released back to the license pool, this number decrements.

Difference between celPoolLicensesInstalled and this object is the number of licenses still available for use.

Depending upon the implementation and the system operational considerations, it is possible that at a given time, this object has a value greater than celPoolLicensesInstalled. This indicates over-subscription to the licenses. The implementation may choose to disallow such situation or treat this situation as temporary and allow the system operation to continue until the implementation specific time period. In this case, more licenses of this type must be installed in the license pool to avoid disruption of the services.
