Use this Knowledge Script to monitor the SQL Server user connections utilization. This script compares the number of user connections that are currently in use to the maximum number of concurrent connections configured for the SQL Server. This script raises an event if the percentage of user connections that are currently in use exceeds the threshold you set.
NOTE:To run this Knowledge Script, you need public and view server state SQL Server permissions
If you have not configured the maximum user connections in the SQL Server then this script does not collect any data.
