Tanel Poder ' snapper does watch not what shows the V$ SESSION

Hi people,

I have a query that has been running for 3 hours.

I decided to launch the snapper ASH mode tool to see what event the session is waiting for:

SQL>@snapper ash 20 1 184
Sampling SID 184 with interval 20 seconds, taking 1 snapshots...


-- Session Snapper v3.64 by Tanel Poder ( http://blog.tanelpoder.com )

--  End of ASH snap 1, end=2014-02-20 15:07:41, seconds=20, samples_taken=96

With V$ SESSION, you must pay attention to the STATE.
