| =head3    start
 | |
|       This function gets called by the monitorctrl module when xcatd starts and 
 | |
|       when monstart command is issued by the user. It starts the daemons and 
 | |
|       does necessary startup process for the Ganglia monitoring. 
 | |
|        p_nodes -- a pointer to an arrays of nodes to be monitored. null means all.
 | |
|        scope -- the action scope, it indicates the node type the action will take place.
 | |
|                 0 means localhost only.
 | |
|                 2 means both localhost and nodes,
 | |
|        callback -- the callback pointer for error and status displaying. It can be null.
 | |
|     Returns:
 | |
|       (return code, message)
 | |
|       if the callback is set, use callback to display the status and error.

| =head3    config
 | |
|       This function configures the cluster for the given nodes. This function is called 
 | |
|       when moncfg command is issued or when xcatd starts on the service node. It will 
 | |
|       configure the cluster to include the given nodes within the monitoring domain. This 
 | |
|       calls two other functions called as confGmond and confGmetad which are used for configuring
 | |
|       the Gmond and Gmetad configuration files respectively.
 | |
|     Arguments:
 | |
|        p_nodes -- a pointer to an arrays of nodes to be added for monitoring. none means all.
 | |
|        scope -- the action scope, it indicates the node type the action will take place.
 | |
|                 0 means localhost only. 
 | |
|                 2 means localhost and nodes, 
 | |
|        callback -- the callback pointer for error and status displaying. It can be null.
