I don't think so, but it can be derived from the byte / request
counters.

Byte hit ratio:
1 - cacheHttpOutKb / cacheServerInKb

Request hit ratio (excluding errors, i think):
cacheHttpHits / cacheClientHttpRequests

All parameters above are in
  
....private.nlanr.squid.cachePerf.cacheProtoStats.cacheProtoAggregateStats.*

There is a small naming inconsistency under cacheProtoAggregateStats:
cacheClientHttpRequests should probably be named cacheHttpRequests to
match the other related parameters.
