m0_net_test_mps_add()

m0_time_t m0_net_test_mps_add	(	struct m0_net_test_mps *	mps,
		unsigned long	messages,
		m0_time_t	timestamp
	)

Add sample to the MPS statistics if time interval [mps->ntmps_last_time, timestamp] is greater than mps->ntmps_interval. This function will use previous call (or initializer) parameters to calculate MPS: number of messages [mps->ntmps_last_nr, messages] in the time range [mps->ntmps_last_time, timestamp].

Parameters

mps	MPS statistics structure.
messages	Total number of messages transferred.
timestamp	Timestamp of messages value.

Returns

Value will not be added to the sample before this time.

m0_net_test_mps_init()

void m0_net_test_mps_init	(	struct m0_net_test_mps *	mps,
		unsigned long	messages,
		m0_time_t	timestamp,
		m0_time_t	interval
	)

Initialize MPS statistics.

Parameters

mps	MPS statistics structure.
messages	Next call to m0_net_test_mps_add() will use this value as previous value to measure number of messages transferred in time interval.
timestamp	The same as messages, but for time difference.
interval	MPS measure interval. m0_net_test_mps_add() will not add sample to stats if time from last addition to statistics is less than interval.
