Anyone know why the following two are different?

SQL> select metric_name, value from v$sysmetric where metric_name =
'Session Count';

METRIC_NAME                                                           VALUE
---------------------------------------------------------------- ----------
Session Count                                                            84

SQL>
SQL> select Count(*) from v$session;

  COUNT(*)
----------
        58

Thanks

Kyle
