B. Check the rate of change in the statis value Qcache_hits and compare that to the rate of change of
Qcache_not_cached.
C. Check the difference between the InnoDB status values "Log Sequence number" and "Last
Checkpoint" positions then compare that to the total size of the redo log.
D. Check the difference between the InooDB status values "Trx id counter" and "Purge done for" and compare to the state substatus of the main "Main thread"
