=head3 preprocess_monstart
|
|
This function handles the syntax checking for monstart command,
|
|
turn on the given monitoring plug-in to the 'monitoring' table.
|
|
Arguments:
|
|
callback - the pointer to the callback function.
|
|
args - The format of the args is:
|
|
[-h|--help|-v|--version] or
|
|
name [noderange] [-r|--remote]
|
|
where
|
|
name is the monitoring plug-in name. For example: rmcmon.
|
|
The specified plug-in will be invoked for monitoring the xCAT cluster.
|
|
noderange a range of nodes to be monitored. Default is all.
|
|
-r|--remote indicates that both monservers and the nodes need to be called to start
|
|
the monitoring. The defaults is monservers only.
|
|
Returns:
|
|
(0, $modulename, $nodestatutmon, $scope, \@nodes) for success. scope is the scope of the
|
|
actions. 1 means monervers only, 2 means both nodes and monservers.
|
|
(1, "") for unsuccess. The error messages are returns through the callback pointer.

|
|
This function adds the given module name into the monitoring table and

settings into the monsetting table.
|
|
Arguments:
|

request -- a hash table which contains the command name and the arguments.
|
|
callback - the pointer to the callback function.
|
|
args - The format of the args is:
|
|
[-h|--help|-v|--version] or
|
|
name [-n|--nodestatmon] [-s|--settings ...]
|
|
where
|
|
name is the monitoring plug-in name. For example: rmcmon.
|
|
The specified plug-in will be registered and invoked
|
|
for monitoring the xCAT cluster.
|
|
-n|--nodestatmon indicates that this plug-in will be used for feeding the node liveness
|
|
status to the xCAT nodelist table. If not specified, the plug-in will not be used
|
|
for feeding node status to xCAT.
|
|
-s|--settings settings are used by the plug-in to customize it behavor.
|
|
Returns:
|

=head3 preprocess_moncfg
|
|
This function handles the syntax checking for moncfg command.
|
|
Arguments:
|
|
callback - the pointer to the callback function.
|
|
args - The format of the args is:
|
|
[-h|--help|-v|--version] or
|
|
name [noderange] [-r|--remote]
|
|
where
|
|
name is the monitoring plug-in name. For example: rmcmon.
|
|
The specified plug-in will be invoked for configuring the cluster to monitor the nodes.
|
|
noderange a range of nodes to be configured for. Default is all.
|
|
-r|--remote indicates that both monservers and the nodes need to configured.
|
|
The defaults is monservers only.
|
|
Returns:
|
|
(0, $modulename, $nodestatutmon, $scope, \@nodes) for success. scope is the scope of the
|
|
actions. 1 means monervers only, 2 means both nodes and monservers.
|
|
(1, "") for unsuccess. The error messages are returns through the callback pointer.
