Performance Metric Current Total
Pages Written Out The number of pages written from the cache
back to disk. A database page is written to
disk whenever a read-write page has been
modified and then subsequently deleted from
the cache. Pages are deleted from the
database cache when the cache is full and a
directory operation requires a database page
that is not currently stored in cache.
Read-Only Page Evicts The number of read-only pages discarded
from the cache to make room for new pages.
Read-Write Page Evicts The number of read-write pages discarded
from the cache to make room for new pages.
This value differs from Pages Written Out in
that these are discarded read-write pages that
have not been modified.
