Can someone tell me what is meant by the following data from sl_status?

  st_origin | st_received | st_last_event |      st_last_event_ts      | 
st_last_received |    st_last_received_ts    | st_last_received_event_ts 
  | st_lag_num_events | st_lag_time
-----------+-------------+---------------+----------------------------+------------------+---------------------------+----------------------------+-------------------+-------------
          1 |           2 |         73226 | 11/18/2008 09:52:03.588658 | 
            73226 | 11/18/2008 09:54:45.17624 | 11/18/2008 
09:52:03.588658 |                 0 | @ 2.25 secs
(1 row)

That is, 'st_origin' == 1.  Does 1 indicate a particular status?  Same 
for 'st_received', what does the value 2 tell me?

Is 2.25 secs st_lag_time good?

Thanks for any info.
