Monitor traffic b/w SQL server and front end

I want to monitor SQL traffic b/w Front End and SQL server. What could be the best approach for this ?

Reason :

In our uls logs , we are getting message :

Process : OWSTIMER.EXE (_x-_-_)
Thread ID : _x-_-_
Area : SharePoint Foundation
Category : Database
Event ID : f-_-
Level : Monitorable

Message :

A large block of literal text was sent to sql. This can result in blocking in sql and excessive memory use on the front end. Verify that no binary parameters are being passed as literals, and consider breaking up batches into smaller components. If this request is for a SharePoint list or list item, you may be able to resolve this by reducing the number of fields.
