<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: License Information
On the License Information tab, you can view information about your license and enter your license key.
This documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.
If 15 minutes (900) seconds have passed since your last credential-based login and you open a setup page from a different setup page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.
This option is not available in PRTG Hosted Monitor.

Number of Sensors
|
Shows the number of sensors that you can use in PRTG. If you reach the limit, PRTG automatically sets each new sensor that you add to the Paused status.
Editions that allow an unlimited number of sensors do not restrict the number of possible sensors by license, so you can create sensors until you reach the performance limit. This means that you can use about 10,000 sensors per PRTG core server. However, this number depends on the performance of the PRTG core server system, and sensors and scanning intervals.
For more information, see section System Requirements.

Deactivate this License

This is necessary, for example, when you move PRTG to a different computer, because a PRTG license can be active on only one computer at the same time. Once you have deactivated the license, the PRTG installation on this computer reverts to the Freeware Edition after a grace period of 30 days.
