I am trying to monitor a SQL Server 2012. The server uses sa crudentials, so I am using that for the DB connection.

When I telnet to the SQL server on port 1433 I get a blank screen, indicating the port is not being blocked.
I am able to login to the SQL server from command prompt on SQL server using SQLCMD -U sa -P sapassword

Any ideas?

When you ran the wizard, did you enter a value for both Instance and Port? It should be only one or the other, not both.

Thanks for the tip. I was inputting values for both instance and port #.

When I just put in a port number, i get NULL values.
When i input the instance name, I get cannot connect to database.

Im happy to just use the port number, since its connecting to the db. Any ideas as to why the NULL value is appearing?

Can you show us the actual command that you are running from the command line? Hide the sensitive data.
