description of a statistics value group
Definition: stat_item.h:43
const struct osmo_stat_item_group_desc * desc
Pointer to the counter group class.
Definition: stat_item.h:61
int osmo_stat_item_discard(const struct osmo_stat_item *item, int32_t *idx)
Skip all values of the item and update idx accordingly.
Definition: stat_item.c:176
int class_id
The class to which this group belongs.
Definition: stat_item.h:49
const char * group_description
The human-readable description of the group.
Definition: stat_item.h:47
struct osmo_stat_item_group * osmo_stat_item_group_alloc(void *ctx, const struct osmo_stat_item_group_desc *desc, unsigned int idx)
Allocate a new group of counters according to description.
Definition: stat_item.c:50
unsigned int num_values
number of values to store
Definition: stat_item.h:38
struct osmo_stat_item_value values[0]
value fifo
Definition: stat_item.h:30
const char * description
description of the item
Definition: stat_item.h:36
int osmo_stat_item_init(void *tall_ctx)
Initialize the stat item module.
Definition: stat_item.c:194
const char * unit
unit of a value
Definition: stat_item.h:37
const unsigned int num_items
The number of values in this group.
Definition: stat_item.h:51
unsigned int idx
The index of this value group within its class.
Definition: stat_item.h:63
int32_t last_value_index
the index of the freshest value
Definition: stat_item.h:26
int osmo_stat_item_get_next(const struct osmo_stat_item *item, int32_t *idx, int32_t *value)
Retrieve the next value from the osmo_stat_item object. If a new value has been set, it is returned. The idx is used to decide which value to return. On success, *idx is updated to refer to the next unread value. If values have been missed due to FIFO overflow, *idx is incremented by (1 + num_lost). This way, the osmo_stat_item object can be kept stateless from the reader's perspective and therefore be used by several backends simultaneously.
