If your session is just sitting, that's not surprising.  I think stats
updates are only transmitted to the collector at transaction end (and
even then, only if it's been at least N msec since the last transmission
from the current session).

Hi, my transaction ended, that I waited 1 min and queried the stat.
I had to wait for session end in order to see the updeted stats.
Did you mean "...to the collector at SESSION end"?
