Data Structure Documentation

◆ fr_stats_entry_t

struct fr_stats_entry_t

Define a statistics mapping between dictionary attribute and a field in an internal structure.

Note that the data types used in the internal structure have to match the fr_type_t.

Definition at line 38 of file stats.h.

Data Fields
struct fr_stats_entry_t.flags	flags
char const *	name	Attribute name.
int	number	attribute number, so that numbers are consistent
size_t	offset	from start of the structure
fr_type_t	type	data type for this statistics

◆ fr_stats_entry_t.flags

struct fr_stats_entry_t.flags

Definition at line 42 of file stats.h.

Data Fields
bool	counter	data type is a counter (can add them)
bool	gauge	data type is a gauge (take the maximum)

◆ fr_stats_struct_t

struct fr_stats_struct_t

Define a statistics mapping between a public name and an entire internal structure.

Definition at line 55 of file stats.h.

Collaboration diagram for fr_stats_struct_t:

Data Fields
char const *	name	of this structure for public consumption
fr_stats_entry_t	table[]	of mappings

Macro Definition Documentation

◆ STATS_ENTRY_TERMINATOR

#define STATS_ENTRY_TERMINATOR { .attr = NULL }

Function Documentation

◆ fr_stats_attr_init()

int fr_stats_attr_init	(	fr_dict_attr_t *	parent,
		fr_stats_struct_t const *	stats
	)

Define dictionary attributes for a given statistics structure.

Parameters

parent	the parent attribute under which statistics are defined
stats	the statistics mapping structure.

Returns

<0 on error
0 on success

◆ fr_stats_pair_add()

int fr_stats_pair_add	(	fr_pair_t *	parent,
		fr_stats_struct_t const *	stats,
		void const *	ctx
	)

Add statistics VPs for a particular struct / context.
