=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:
|
|
(error code, error message)

=head3 deconfig
|
|
This function de-configures the cluster for the given nodes. This function is called
|
|
when mondecfg command is issued by the user. This function restores the original Gmond
|
|
and Gmetad configuration files by calling the deconfGmond and deconfGmetad functions
|
|
respectively.
|
|
|
|
Arguments:
|
|
p_nodes -- a pointer to an arrays of nodes to be removed for monitoring. none means all.
|
|
scope -- the action scope, it indicates the node type the action will take place.
|
|
0 means local host only.
|
|
2 means both local host and nodes,
|
|
callback -- the callback pointer for error and status displaying. It can be null.
