20 14 Character 80 STOBPG_PGDBR_TBL
20 14 Unsigned 4 STOBPG_PGDBR(1:20) Number of times a block of the
corresponding size was read. Each
index number from 1 to 19
corresponds to the block size
number. Example: PGDBR(8) = the
number of times a block of 8 pages
was read. For index number 20,
this is the number of times a
block of 20 or more pages was
read.
100 64 Character 80 STOBPG_PGDBM_TBL
100 64 Unsigned 4 STOBPG_PGDBM(1:20) Number of times a block of the
corresponding size was migrated.
Each index number from 1 to 19
corresponds to the block size by a
factor of 2. Example: PGDBM(1) =
the number of times a block of 1
or 2 pages was migrated. PGDBM(6)
= the number of times a block of
11 or 12 pages was migrated. For
index number 20, this is the
number of times a block of 39 or
more pages was migrated.
180 B4 Character 80 STOBPG_PGDBS_TBL
180 B4 Unsigned 4 STOBPG_PGDBS(1:20) Number of times a block of the
corresponding size was written.
Each index number from 1 to 19
corresponds to the block size by a
factor of 2. Example: PGDBS(1) =
the number of times a a block of 1
or 2 pages was written. PGDBS(6) =
the number of times a block of 11
or 12 pages was written. For index
number 20, this is the number of
times a block of 39 or more pages
was written.
