=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.
Returns:
