  Grant Permissions:
  
  Assign the required permissions to the login for the monitor schema. You can do this by executing the following SQL command:
  USE [YourDatabaseName];
  ALTER USER [YourUserName] WITH DEFAULT_SCHEMA=[YourMonitorSchema];
  GRANT SELECT, INSERT, UPDATE, DELETE ON SCHEMA::[YourMonitorSchema] TO [YourUserName];
