We've been using average-read-time value in place for TotalReads, TotalFailedReads, TotalWrites, and TotalFailedWrites. Since we do not have the data for TotalReads, TotalFailedReads, TotalWrites, and TotalFailedWrites we need to replace these four fields with some of the following:
number-of-entries
number-of-entries-in-memory
average-remove-time
number-of-locks-available
average-replication-time
number-of-locks-held
average-write-time
off-heap-memory-used
passivations
cache-loader-loads
prepares
cache-loader-misses
read-write-ratio
cache-loader-stores
remove-hits
remove-misses
replication-count
replication-failures
rollbacks
commits
stores
success-ratio
evictions
hit-ratio
hits

Let's pick 4-6 most useful fields and we'll enable admins to choose their own stat fields in subsequent versions.
