27/*
28 * A kernel and user space statistics gathering API + infrastructure.
29 *
30 * Author: Lawrence Stewart <lstewart@netflix.com>
31 *
32 * Things to ponder:
33 * - Register callbacks for events e.g. counter stat passing a threshold
34 *
35 * - How could this become SIFTRv2? Perhaps publishing records to a ring
36 * mapped between userspace and kernel?
37 *
38 * - Potential stat types:
39 * RATE: events per unit time
40 * TIMESERIES: timestamped records. Stored in voistate?
41 * EWMA: Exponential weighted moving average.
42 *
43 * - How should second order stats work e.g. stat "A" depends on "B"
44 *
45 * - How do variable time windows work e.g. give me per-RTT stats
46 *
47 * - Should the API always require the caller to manage locking? Or should the
48 * API provide optional functionality to lock a blob during operations.
49 *
50 * - Should we continue to store unpacked naturally aligned structs in the
51 * blob or move to packed structs? Relates to inter-host
52 * serialisation/endian issues.
