Measures reported by TSLicenseUtilTest
Without an RDS CAL, a Microsoft RDS client cannot connect to a Microsoft RDS server and access the applications operating on that server. It is hence imperative that administrators periodically check whether/not the Microsoft RDS License server has enough RDS CALs to support the current and future user load of the Microsoft RDS server. To achieve this, administrators can use the TSLicenseUtilTest test.
For every Microsoft RDS server that is managed by the license server, this test reports the number, type, and usage of RDS CALs installed on the Microsoft RDS License server under a particular Key pack ID and purchased under a specific License program or Purchase method (this can be, Unknown, Retail, Built-in, Volume, Concurrent, Temporary, Open). Optionally, you can also group license usage by Microsoft RDS server alone (and not by key pack ID and purchase method). Using these statistics, you can rapidly detect probable license shortages and accurately point to the Microsoft RDS server that will potentially run out of licenses.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Cal_type |
Indicates the CAL type of the licenses for this Microsoft RDS server, installed under this Key pack ID and license program. |
Number |
CALs apply to either a “device” (as defined in the license agreement) or a “user”. A business is free to choose either mode. In Per-User mode, a CAL is purchased to allow one user to connect to the server software. Any user can connect, but only one user may use a given CAL at any given time. Any number of CALs can be purchased to allow five, five hundred, or any number of users to simultaneously connect to the server. Any number of devices may connect to the server software, but only a set number of users can connect to it at once.
Per-device mode operates in much the same way, but limits connections made by devices, rather than users. One CAL enables one device to connect to and use the server software, regardless of how many users are connecting.
If the CALs apply to a user, then the value of this measure will be Per User. If the CALs apply to a device, then the value of this measure will be Per Device. In the case of invalid CALs, the value of this measure will be Not Valid. The numeric values that correspond to these measure values have been discussed in the table below:
| Measure Value |
Numeric Value |
| Per User |
1 |
| Per Device |
0 or 3 |
| Not Valid |
2 |
Note:
By default, the measure reports the Measure Values listed in the table above to indicate the CAL type. However, in the graph of this measure, the same will be represented using the numeric equivalents only.
This measure will not be available for the Total descriptor.
You can use the detailed diagnosis of this measure to know the license program and expiration date of each license. |
| Total_license |
Indicates the total number of licenses installed for this Microsoft RDS server under this key pack ID and license program. |
Number |
This measure will not be available for the Total descriptor. |
| Available_license |
Indicates the number of licenses under this key pack ID and license program that are still to be used by this Microsoft RDS server. |
Number |
A high value is desired for this measure.
This measure will not be available for the Total descriptor. |
| Issued_license |
Indicates the number of licenses under this key pack ID and license program that are currently used by this Microsoft RDS server. For the Total descriptor, this measure reports the number of licenses currently used by this Microsoft RDS server across all relevant key pack IDs and license programs. |
Number |
A low value is desired for this measure. Compare the value of this measure for the Total descriptor across all Microsoft RDS servers to identify which Microsoft RDS server is over-utilizing the CALs.
Using the detailed diagnosis of this measure, you can view the complete details of license usage. This includes the the License ID of every license installed under a key pack, the license program under which each license was purchased, who it was issued to and when, the expiry date of license and its current status. |
| License_util |
Indicates the percentage of licenses under this key pack ID and license program that are currently used by this Microsoft RDS server. |
Percent |
A value close to 100% indicates excessive CAL utilization. This in turn implies that too many users are connecting to the Microsoft RDS server. You may want to install additional licenses to ensure that subsequent users are able to connect to and work with the Microsoft RDS server. This measure will not be available for the Total descriptor.
