  • Requires .NET 4.5 or later on the probe system.
  • Define credentials, custom port (if required), and timeout in settings section Credentials for Database Management Systems of the parent device, or in the settings of a group or probe above.
  • Your SQL query must be stored in a file on the system of the probe the sensor is created on. If you use it on a remote probe, store the file on the system running the remote probe. In a cluster setup, copy the file to every cluster node.

Hello there,
we appreciate your contact.

A quick (and frustration free) way to test this sensor is to actually run it manually. On the PRTG Server, head to C:\Program Files (x86)\PRTG Network Monitor\Sensor System\ and run SQLv2.exe It will give you a GUI from where you can test the connection to your SQL Server. Enter a simply query were it reads "Insert Query Here!" and configure the necessary credentials in this tool. Please let us know how this goes.

If this test succeeds, please double-check that you've entered exactly the same credentials in PRTG:

If this test fails, please install the SQL Management Console for your SQL server on the PRTG host and confirm that you're able connect using this tool (with the same credentials) instead.

Best Regards,
