Function Documentation

hs_metrics_get_stores()

const smartlist_t* hs_metrics_get_stores

(

void

)

Return a list of all the onion service metrics stores. This is the function attached to the .get_metrics() member of the subsys_t.

Definition at line 213 of file hs_metrics.c.

hs_metrics_service_free()

void hs_metrics_service_free

(

hs_service_t *

service

)

Free the metrics store in the given service.

Definition at line 244 of file hs_metrics.c.

hs_metrics_service_init()

void hs_metrics_service_init

(

hs_service_t *

service

)

Initialize the metrics store in the given service.

hs_metrics_update_by_ident()

void hs_metrics_update_by_ident	(	const hs_metrics_key_t	key,
		const ed25519_public_key_t *	ident_pk,
		const uint16_t	port,
		const char *	reason,
		int64_t	n,
		int64_t	obs
	)

Update the metrics key entry in the store of a service identified by the given identity public key. The port, if non 0, and the reason label, if non NULL, are used to find the correct metrics entry. The value n is the value used to update the entry.

This is used by callsite that have access to the key but not the service object so an extra lookup is done to find the service.

Definition at line 190 of file hs_metrics.c.

hs_metrics_update_by_service()

void hs_metrics_update_by_service	(	const hs_metrics_key_t	key,
		const hs_service_t *	service,
		uint16_t	port,
		const char *	reason,
		int64_t	n,
		int64_t	obs
	)

Update the metrics key entry in the store in the given service. The port, if non 0, and the reason label, if non NULL, are used to find the correct metrics entry. The value n is the value used to update the entry.
