Skex, show status like 'Qcache%'; Will give you status of the query cache. There isn't a way to tell if a query result came from the cache or not other than the time it took to return or if it's the only query ran between checks of the show status. Neither of these methods is very reliable. Cache hits from Qcache_hits and Com_select from show status like 'Com_select'; should be enough to tune the cache. Alternatly the mytop utility will show you cache hit miss ratios on the fly.
