Monitor network traffic

  • Is there a way to monitor network bandwidth on a SQL Server? My network admin is telling me that we r using over 1 terabyte of bandwidth per hour and I am not sure how to capture that. Through Perfmon?DMV?

  • There are built in metrics in Permon that you can use. Here's an article. Chapter 3 (or maybe 4, I forget) of my book also discusses monitoring the network. There's little you can do about network traffic directly though, so this is a bit of a waste of time. Instead you need to ensure that queries are only moving the data they need to move and only when they need to move it. Proper filtering makes all the difference.

    "BandWidth"??? Bandwidth where?  "Bandwidth" applies to many different areas.  What is meant here?

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
