/**
Changelog:
Version 0.4: Added round() to Joins_without_indexes_per_day to remove exponents for large query sets.
Version 0.3: 11:57 AM 10/13/2008
- Correct where Percent_innodb_cache_hit_rate and/or Percent_innodb_cache_write_waits_required could have been 0
Version 0.2: 10:43 AM 10/13/2008
- Corrected error where replication not enabled stopped the monitoring completely (If you had your warning on strict, the server could see things like: Notice: Undefined variable: Slave_IO_Running)
- Ditto for Last_Errno, Last_Error
