=head3 startmon
|
|
This function registers the given monitoring plug-in to the 'monitoring' table.
|
|
xCAT will invoke the monitoring plug-in to start the 3rd party software, which
|
|
this plug-in connects to, to monitor the xCAT cluster.
|
|
Arguments:
|
|
callback - the pointer to the callback function.
|
|
args - The format of the args is:
|
|
[-h|--help|-v|--version] or
|
|
name [-n|--nodestatmon]
|
|
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.
|
|
Returns:
|
|
0 for success. The output is returned through the callback pointer.
|
|
1. for unsuccess. The error messages are returns through the callback pointer.

=head3 stopmon
|
|
This function unregisters the given monitoring plug-in from the 'monitoring' table.
|
|
xCAT will ask the monitoring plug-in to stop the 3rd party software, which
|
|
this plug-in connects to, to monitor the xCAT cluster.
|
|
Arguments:
|
|
callback - the pointer to the callback function.
|
|
args - The format of the args is:
|
|
[-h|--help|-v|--version] or
|
|
name
|
|
where
|
|
name is the monitoring plug-in name. For example: rmcmon.
|
|
The specified plug-in will be un-registered and stoped
|
|
for monitoring the xCAT cluster.
|
|
Returns:
|
|
0 for success. The output is returned through the callback pointer.
|
|
1. for unsuccess. The error messages are returns through the callback pointer.
