the class Agent method startAgent.

/**
     *  This method starts up the monitoring agent from the
     *  common/ConfigMonitoring module (load-on-startup or at the
     *  end of AMSetupServlet/configuration).  Since web-app startup
     *  is sensitive to exceptions in load-on-startup stuff, this has
     *  quite a few try/catch blocks.
     *
     *  If any of HTML, SNMP, or RMI adaptors has a problem getting created
     *  or started, attempts to create/start the others will be made; If
     *  at least one adaptor is started, monitoring will be "active"
     *  (Agent.isRunning() will return true).
     *
     *  @param monConfig SSOServerMonConfig structure of OpenAM configuration
     *  @return 0 (zero) if at least one of HTML/SNMP/RMI adaptors started up;
     *     MON_CONFIG_DISABLED:
     *       if monitoring configured as disabled
     *     MON_MBEANSRVR_PROBLEM:
     *       if MBeanServer problem encountered
     *     MON_RMICONNECTOR_PROBLEM:
