Function Documentation

fr_stats_bins()

void fr_stats_bins	(	fr_stats_t *	stats,
		fr_time_t	start,
		fr_time_t	end
	)

Sort latency times into bins.

This solves the problem of attempting to keep min/max/avg latencies, whilst not knowing what the polling frequency will be.

Parameters

[out]	stats	Holding monotonically increasing stats bins.
[in]	start	of the request.
[in]	end	of the request.
