Hi Lisa,

IIRC, the first line of vmstat gives you cumulative values since system boot. And "2 10" means "every 2 seconds, 10 times" (on Solaris, at any rate).

Cheers,

     2.  vmstat - look at the two columns that start with pg.  Read the man
     page and it will explain it to you in detail. Also, when you use
     vmstat be sure to give it an interval (like vmstat 2 10 - this means
     display stats once every 2 seconds for a duration of 10 seconds).  The
     first line returned by vmstat will always be garbage (same with
     iostat).
