Functions

struct osmo_stat_item_grouposmo_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.
 
static void osmo_stat_item_group_udp_idx (struct osmo_stat_item_group *grp, unsigned int idx)
 
void osmo_stat_item_group_free (struct osmo_stat_item_group *grp)
 Free the memory for the specified group of counters.
 
void osmo_stat_item_set (struct osmo_stat_item *item, int32_t value)
 
int osmo_stat_item_init (void *tall_ctx)
 Initialize the stat item module.
 
struct osmo_stat_item_grouposmo_stat_item_get_group_by_name_idx (const char *name, const unsigned int idx)
 Search for item group based on group name and index.
 
const struct osmo_stat_itemosmo_stat_item_get_by_name (const struct osmo_stat_item_group *statg, const char *name)
 Search for item group based on group name.
 
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.
 
static int32_t osmo_stat_item_get_last (const struct osmo_stat_item *item)
 Get the last (freshest) value.
 
int osmo_stat_item_discard (const struct osmo_stat_item *item, int32_t *idx)
 Skip all values of the item and update idx accordingly.
 
int osmo_stat_item_discard_all (int32_t *idx)
 Skip all values of all items and update idx accordingly.
 
int osmo_stat_item_for_each_item (struct osmo_stat_item_group *statg, osmo_stat_item_handler_t handle_item, void *data)
 Iteate over all items.
 
int osmo_stat_item_for_each_group (osmo_stat_item_group_handler_t handle_group, void *data)
