What does hit=xxx miss=xxx mean?

Asked by PrivateUser132781

I am confused by some of the messages in the U1 logs. For example in the following line:

2009-12-18 22:52:59,236 - ubuntuone.SyncDaemon.Main - NOTE - ---- MARK (state: SCANNING_WITH_METAQ; queues: metadata: 4; content: 0; hash: 0, fsm-cache: hit=54047 miss=176343)

I understand the "queues" entry, but don't understand what the "fsm-cache" entry means, and in particular the hit= and miss= parts

Hi Eduard,

The "fsm-cache: hit=54047 miss=176343" basically is stat information about the metadata cache.
 - hit: the number of times syncdaemon retrieved a metadata node that was in the cache
 - miss: the number of times syncdaemon retrieved a metadata node that wasn't in the cache and needed to read it from disk

Reards,

Can you help with this problem?
