This monitoring script connects to database, does 'SELECT VERSION' and then
'SHOW STATUS' or 'SHOW GLOBAL STATUS' (for version 5.0.2 or newer of mysql)
or other query you specify with '-q'. It then allows to select variables
from 'SHOW STATUS' and check them against critical and warning thresholds(s)
Status data can also be used for performance output.
