extended events duration in milliseconds or microseconds?

  • When you view the Extended Events "Watch Live Data" is the duration in milliseconds or microseconds? I'm assuming it's milliseconds, but if you look at the timestamp difference from start to complete it doesn't add up to the duration amount? It looks like it's just the difference between the timestamps?

  • Pretty sure it's microseconds on rpc_completed and sql_batch_completed. However, it does depend on which event you're looking at. Unfortunately, Microsoft has been inconsistent and hasn't documented well. Vote that up so that it gets more attention.

  • I'm using sql_statement_started and sql_statement_completed. Microseconds would make sense. When you say "vote it up" where do you do that? Appreciate the help.

    The "vote up" is in the connect item that Grant linked to in his comment.

  • awesome thanks all.

  • Sorry I wasn't clear. What Jason said. They need to either make it consistent or give us good documentation.
