 * Gracewatch 1.0
 * Matthew Boehm <matthew@matthewboehm.com>
 *
 * Gracewatch is a multi-threaded MySQL monitoring solution developed for
 * a client that had no in-house monitoring team.
 * 
 * Using libConfig (http://www.hyperrealm.com/libconfig/), gracewatch reads
 * a list of servers and credentials and spawns a pthread for each server.
 * The thread connects to the host and every minute preforms a mysql_ping()
