stats_register_alias_counter()

StatsCluster* stats_register_alias_counter	(	gint	level,

		gint	type,
		StatsCounterItem *	aliased_counter
	)

stats_register_and_increment_dynamic_counter()

void stats_register_and_increment_dynamic_counter	(	gint	stats_level,
		const StatsClusterKey *	sc_key,
		time_t	timestamp
	)

stats_register_associated_counter()

void stats_register_associated_counter	(	StatsCluster *	sc,
		gint	type,
		StatsCounterItem **	counter
	)

stats_register_associated_counter: @sc: the dynamic counter that was registered with stats_register_dynamic_counter @type: the type that we want to use in the same StatsCluster instance @counter: the returned pointer to the counter itself

This function registers another counter type in the same StatsCounter instance in order to avoid an unnecessary lookup.

stats_register_counter()

StatsCluster* stats_register_counter	(	gint	stats_level,
		const StatsClusterKey *	sc_key,
		gint	type,
		StatsCounterItem **	counter
	)

stats_register_counter: @stats_level: the required statistics level to make this counter available @component: a reference to the syslog-ng component that this counter belongs to (SCS_*) @id: the unique identifier of the configuration item that this counter belongs to @instance: if a given configuration item manages multiple similar counters this makes those unique (like destination filename in case macros are used) @type: the counter type (processed, dropped, etc) @counter: returned pointer to the counter

This function registers a general purpose counter. Whenever multiple objects touch the same counter all of these should register the counter with the same name. Internally the stats subsystem counts the number of users of the same counter in this case, thus the counter will only be freed when all of these uses are unregistered.

stats_register_dynamic_counter()

StatsCluster* stats_register_dynamic_counter	(	gint	stats_level,
