[[email protected] ~]$ /usr/local/nagios/libexec/check_mysql_health --hostname=IPRFDECSQABD01 --port=3306 --username=mysql_monitor --password="********* " --database=information_schema --mode connection-time --warning 1 --critical 5
CRITICAL - cannot connect to information_schema. Unknown MySQL server host '' (2)

/usr/local/nagios/libexec/check_mysql_health --hostname=IPRFDECSQABD01

The --hostname argument needs to be a resolvable address. Unless you're using some different (NIS+, yp, wins) methods of looking up hosts, this should be set to the fully qualified DNS or IP address of the MySQL server.
