Perhaps publishing records to a ring 38 * mapped between userspace and kernel? 39 * 40 * - Potential stat types: 41 * RATE: events per unit time 42 * TIMESERIES: timestamped records. Stored in voistate? 43 * EWMA: Exponential weighted moving average. 44 * 45 * - How should second order stats work e.g. stat "A" depends on "B" 46 * 47 * - How do variable time windows work e.g. give me per-RTT stats 48 * 49 * - Should the API always require the caller to manage locking? Or should the 50 * API provide optional functionality to lock a blob during operations. 51 * 52 * - Should we continue to store unpacked naturally aligned structs in the 53 * blob or move to packed structs? Relates to inter-host 54 * serialisation/endian issues. 55 */ 56 57 #ifndef _SYS_STATS_H_ 58 #define _SYS_STATS_H_ 59 60 #include <sys/limits.h> 61 #ifdef DIAGNOSTIC 62 #include <sys/tree.h> 63 #endif
