V$SYSSTAT has a NAME attribute. V$SESSTAT doesn't. So seeing the name
when you're using V$SESSTAT requires a join with V$STATNAME.

You are right, that v$statname is not needed when querying v$sysstat,
since v$sysstat has "name" column.
But, if you look at v$sesstat:
SQL> describe v$sesstat;
Name
SID
STATISTIC#
VALUE
Ryan,
V$sysstat is system wide statistics. It contains name, value and
statistic# and class.
V$statname is used mostly as a lookup.
V$sesstat is session stats which does not contain the *statistic name*
column.
When joined with v$statname (statistic# column), the statistic name
and values can b

v$statname is a lookup table for the statistic# that appears in v$sesstat
and v$sysstat. You use it in most queries on those tables unless you're
named Tanel and have memorised the statistic numbers. =)

This view seems to be a smaller subset of v$sysstat? When is it useful?
