pcmk_controller_status()

int pcmk_controller_status	(	xmlNodePtr *	xml,
		const char *	node_name,
		unsigned int	message_timeout_ms
	)

Get and output controller status.

Parameters

[in,out]	xml	Destination for the result, as an XML tree
[in]	node_name	Name of node whose status is desired (NULL for DC)
[in]	message_timeout_ms	How long to wait for a reply from the pacemaker-controld API. If 0, pcmk_ipc_dispatch_sync will be used. Otherwise, pcmk_ipc_dispatch_poll will be used.

Returns

Standard Pacemaker return code

Definition at line 497 of file pcmk_cluster_queries.c.

pcmk_designated_controller()

Parameters

[in,out]	xml	Destination for the result, as an XML tree
[in]	message_timeout_ms	How long to wait for a reply from the pacemaker-controld API. If 0, pcmk_ipc_dispatch_sync will be used. Otherwise, pcmk_ipc_dispatch_poll will be used.

Returns

Parameters

[in,out]	xml	The destination for the result, as an XML tree
[in]	node_types	Node type(s) to return (default: all)

Returns

Standard Pacemaker return code

Definition at line 887 of file pcmk_cluster_queries.c.

pcmk_pacemakerd_status()

int pcmk_pacemakerd_status	(	xmlNodePtr *	xml,
		const char *	ipc_name,
		unsigned int	message_timeout_ms
	)

Get and output pacemakerd status.

Parameters

[in,out]	xml	Destination for the result, as an XML tree
[in]	ipc_name	IPC name for request
[in]	message_timeout_ms	How long to wait for a reply from the pacemakerd API. If 0, pcmk_ipc_dispatch_sync will be used. Otherwise, pcmk_ipc_dispatch_poll will be used.

Returns

Standard Pacemaker return code

Definition at line 785 of file pcmk_cluster_queries.c.

pcmk_query_node_info()

int pcmk_query_node_info	(	xmlNodePtr *	xml,
		uint32_t *	node_id,
		char **	node_name,
		char **	uuid,
		char **	state,
		bool *	have_quorum,
		bool *	is_remote,
		bool	show_output,
		unsigned int	message_timeout_ms
	)

Get and optionally output node info corresponding to a node ID from the controller.

Parameters

[in,out]	xml	Destination for the result, as an XML tree
[in,out]	node_id	ID of node whose name to get. If NULL or 0, get the local node name. If not NULL, store the true node ID here on success.
[out]	node_name	If not NULL, where to store the node name
[out]	uuid	If not NULL, where to store the node UUID
[out]	state	If not NULL, where to store the membership state
[out]	is_remote	If not NULL, where to store whether the node is a Pacemaker Remote node
[out]	have_quorum	If not NULL, where to store whether the node has quorum
[in]	show_output	Whether to output the node info
[in]	message_timeout_ms	How long to wait for a reply from the pacemaker-controld API. If 0, pcmk_ipc_dispatch_sync will be used. Otherwise, pcmk_ipc_dispatch_poll will be used.

Returns

Standard Pacemaker return code

Note

The caller is responsible for freeing *node_name, *uuid, and *state using free().
