ZFS cache devices and flashcache hit rate statistics

edited Feb 21, 2014 12:00PM in Oracle Solaris ZFS File System (MOSC) 1 commentAnswered


We have a number of Zpools in the 1 - 3 TB range, each with a hundred to two hundred GB of flash cache, defined as cache devices in the pool.

Is there an easy way to get the cache hit rate with in the pool, maybe with kstat?  I am not looking for stats on the memory cache.  I am interested in answers for both Solaris 10 and 11.

Howdy, Stranger!
