=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 all nodes (except localhost),
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:
(error code, error message)

=head3 supportNodeStatusMon
This function is called by the monitorctrl module to check
if Ganglia can help monitoring and returning the node status.
Arguments: None
Returns: 1

#--------------------------------------------------------------------------------
=head3 startNodeStatusMon
This function is called by the monitorctrl module to tell
Ganglia to start monitoring the node status and feed them back
to xCAT. Ganglia will start setting up the condition/response
to monitor the node status changes.
Arguments: None
Returns:
(return code, message)
=cut
#--------------------------------------------------------------------------------
sub startNodeStatusMon {
return ( 0, "started" );

#--------------------------------------------------------------------------------
=head3 stopNodeStatusMon
This function is called by the monitorctrl module to tell
Ganglia to stop feeding the node status info back to xCAT. It will
stop the condition/response that is monitoring the node status.
Arguments: None
Returns:
(return code, message)

=head3 getDiscription
This function returns the detailed description of the plugin inluding the
valid values for its settings in the monsetting tabel.
Arguments: None
Returns: The description

=head3 getPostscripts
This function returns the postscripts needed for the nodes.
Arguments: None
Returns:
The the postscripts. It a pointer to an array with the node group names as the keys
and the comma separated poscript names as the value. For example:
{service=>"cmd1,cmd2", xcatdefaults=>"cmd3,cmd4"} where xcatdefults is a group
of all nodes including the service nodes.
