After using ApexSQL Monitor for a period of time and monitoring a SQL Server instance, without any problem, on the 15th day when trying to add a new SQL Server, the “Number of servers exceeds number of available server licenses. Remaining licenses -1” error warning message is shown when pressing the Add button under the Add instance page:
“The Number of servers exceeds the number of available server licenses. Remaining licenses -1” error warning message appears due to the expiration of the trial period.
The trial version lasts 14 days and the application is fully functional during that time.
